As shown in fig. 1-5, the present invention provides a sewage treatment system, which includes a sewage blending device and a sewage monitoring device 100, wherein the sewage blending device may include a raw slurry tank 210 and a blending tank 230.

The sewage monitoring device is communicated with the allocation tank 230, and the sewage concentration in the allocation tank 230 can be accurately measured continuously in real time. Specifically, with reference to fig. 3 and 4, the sewage monitoring apparatus includes: a steady flow container 10 and a weighing scale.

The flow stabilizing container 10 is provided with a first water inlet 11, a flow stabilizing port 12 and a first overflow port 13. The first water inlet 11, the steady flow port 12 and the first overflow port 13 are all communicated with the cavity of the steady flow container 10. The first water inlet 11 is communicated with the blending pool 230, and sewage in the blending pool 230 enters the flow stabilizing container 10 from the first water inlet 11. The steady flow port 12 is positioned below the first overflow port 13 and used for allowing the sewage in the steady flow container 10 to flow out. The first overflow port 13 is used for overflowing the sewage when the sewage level in the flow stabilizing container 10 rises to the position of the first overflow port 13, so that the sewage in the flow stabilizing container 10 is in an overflowing state. Specifically, the flow rate of the sewage in the blending tank 230 entering the flow stabilizing container 10 from the first water inlet 11 is larger than the flow rate of the sewage flowing out from the flow stabilizing port 12, so that the sewage level in the flow stabilizing container 10 can rise to or exceed the first overflow port 13 to overflow from the first overflow port 13. The processes of sewage entering from the first water inlet 11, overflowing from the first overflow port 13 and flowing out from the steady flow port 12 are performed simultaneously (in real time), so that the sewage in the steady flow container 10 can be always in an overflow state, and further, when the sewage in the steady flow container 10 is in the overflow state, the sewage flows out from the steady flow port 12 at a constant flow rate by utilizing the self gravity, namely, the flow rate of the sewage flowing out from the steady flow port 12 is almost stable and does not change suddenly.

The weigh scale is used to measure the weight of the weigh receptacle 20 and the sewage therein, such as from the blending tank 230. The weighing container 20 is provided with a second water inlet 21, a water outlet 22 and a second overflow port 23, and the second water inlet 21, the water outlet 22 and the second overflow port 23 are all communicated with the cavity of the weighing container 20. The water outlet 22 is positioned below the second water inlet 21 and the second overflow port 23, and the second water inlet 21 is positioned below the steady flow port 12 and is used for receiving the sewage flowing out of the steady flow port 12. The water outlet 22 is used for discharging the sewage in the weighing container 20. The second overflow opening 23 is used for overflowing the sewage when the sewage level in the weighing container 20 reaches the position of the second overflow opening 23. Wherein the flow rate of the sewage flowing out of the steady flow port 12 is larger than that of the sewage flowing out of the water outlet 22, so that the sewage in the weighing container 20 is in an overflow state.

Specifically, sewage flowing out of the constant flow port 12 at a constant flow rate enters the weighing container 20 through the second water inlet 21 of the weighing container 20, the flow rate of the sewage flowing out of the constant flow port 12 is greater than that of the sewage flowing out of the water outlet 22, so that the sewage level in the weighing container 20 can rise to the second overflow port 23 so as to overflow from the first overflow port 13, and the processes of the sewage entering the weighing container 20 from the second water inlet 21, overflowing from the second overflow port 23 and flowing out of the water outlet 22 are performed simultaneously (in real time), so that the sewage in the weighing container 20 can be in an overflow state all the time. Moreover, since the sewage flowing out of the steady flow port 12 flows out at a constant flow rate, that is, the flow rate of the sewage entering the weighing container 20 from the second water inlet 21 is constant, and the flow rate is uniform, the sewage level in the weighing container 20 can be always in a stable state, and the sewage level in an overflow state in the weighing container 20 hardly changes, so that the volume of the sewage in the weighing container 20 hardly changes, the measured weight of the sewage in the weighing container 20 is more accurate, and the calculated sewage concentration in the blending tank 230, for example, is more accurate.

The above-mentioned sewage concentration calculation method may be that, the weight of the weighing container 20 carrying clear water is checked by introducing clear water into the sewage monitoring device, and then the sewage to be measured is introduced into the sewage monitoring device, and the weight difference between the weighing container 20 carrying sewage and the above-mentioned weight difference can obtain the sewage concentration to be measured, and the sewage concentration may be the sewage solid content. Specifically, first, the weighing container 20 is filled with clear water in the sewage monitoring apparatus to obtain a first weight. Then, the sewage to be detected is introduced into the sewage monitoring device, and the program starts to operate concentration (density) calculation after the program set weight reaches the first quality, so that meaningless data of the program are reduced, and the efficiency is higher. The above-mentioned sewage concentration calculation method may also be that the sewage concentration (density) is directly obtained by measuring the weight of the sewage in the weighing container 20 in the sewage monitoring device, and since the volume of the weighing container 20 is constant, the sewage concentration (density) can be obtained by the ratio of the weight (mass) of the sewage in the weighing container 20 to the volume of the weighing container 20.

The sewage detection device can be connected with a digital display to directly display the concentration value, and the concentration value can also be calculated by directly measuring the weight.

Specifically, the inventors found that in the sewage monitoring apparatus of the related art, if the flow rate of sewage flowing into the weighing container 20 is not uniform, sometimes fast or slow, even if the sewage in the weighing container 20 is in an overflow state, the sewage level in the weighing container 20 changes, the sewage level in the weighing container 20 cannot be kept constant, that is, the sewage volume in the weighing container 20 changes, and the measurement is not accurate. Especially in the scene of measuring concrete thick liquid weight, weighing container 20 capacity is great, and weight can reach tens tons when full load, and the liquid level in weighing container 20 is little change, also can lead to weighing container 20 weight to take place great change, leads to the sewage concentration measurement inaccurate. Specifically, when the flow rate of the sewage flowing into the weighing container 20 is not uniform, that is, when the flow rate is fast or slow, even if the sewage in the weighing container 20 is in an overflow state, because the sewage has tension, when the flow rate of the sewage flowing into the weighing container 20 is fast, the second overflow port 23 on the weighing container 20 does not overflow in time, even the liquid level exceeds the second overflow port 23, so that the liquid level of the sewage in the weighing container 20 rises, the liquid level of the sewage changes, and the measurement is inaccurate; similarly, when the sewage flowing into the weighing container 20 flows at a slow speed, the sewage level in the weighing container 20 is lower than the sewage level when the flow speed is higher, which also causes the sewage level to change and the measurement is inaccurate.

In conclusion, the inventors found that the stability of the flow rate of the sewage flowing into the weighing container 20 has a great influence on the accuracy of the measurement result. According to the invention, the flow speed of sewage from the steady flow port 12 of the steady flow container 10 is kept constant by the steady flow container 10 which is in an overflow state in real time (continuously), and sewage with a constant flow speed flows into the weighing container 20 which is in an overflow state in real time (continuously), so that the sewage liquid level in the weighing container 20 is almost kept in a constant state, and the liquid level is almost not changed, therefore, the sewage volume is almost kept unchanged, further, the weight of the weighing container 20 carrying the sewage can be accurately measured in real time continuously, and further, more accurate sewage concentration can be calculated.

Next, referring to fig. 1 and 2, the raw slurry tank 210 serves to accommodate a source of sewage, which may be sewage generated after the mixer truck is washed, sewage from the defective concrete waste, and the like. For example, a cleaning wastewater recycling tank may be installed in a site, and the cleaning wastewater in the tank is transferred to a sand separator and recycled to the slurry tank 210 by a water pump.

In one example, a filter plate may be disposed in the raw slurry tank 210, and the raw slurry tank 210 may be divided into two receiving areas, such as a feeding area and a filtering area, wherein the sewage source may be poured into the feeding area, filtered by the filter plate, and then flowed into the filtering area, so as to filter out larger particulate matters in the sewage.

A first water pump 211 may be provided in the raw stock tank 210 to deliver the sewage in the raw stock tank 10 to a desired location.

The blending tank 230 is used for blending the sewage concentration. The sewage monitoring device 100 is communicated with the blending tank 230 and is used for detecting the sewage concentration in the blending tank 230 in real time. For example, the sewage monitoring device 100 may be located above the blending tank 230. If the sewage concentration in the blending tank 230 meets the set standard concentration, the sewage in the blending tank 230 can be delivered to the finished product tank 240 for the sewage utilization of the mixing plant.

When the concentration of the sewage in the primary pulp tank 210 is lower than the first set concentration, the first water pump 211 delivers the sewage in the primary pulp tank 210 to the blending tank 230. The first set concentration value may be lower than the set standard concentration. In the embodiment of the present invention, a water pump may not be used, and the sewage in the raw slurry tank 210 may flow into the blending tank 230 by its own weight. For example, the outlet of the stock tank 210 is higher than the blending tank 230. The first set concentration can be set according to actual needs on site, for example, a concentration value is preset in a program, or a required concentration value is manually input.

During the use, can detect the sewage in the magma pond 210 earlier, if the sewage concentration in the former magma pond 210 is less than when first settlement concentration, the explanation can directly be utilized, can directly carry the sewage in the former magma pond 210 to the allotment pond through first water pump 211 this moment.

According to the invention, the sewage in the primary pulp tank 210 is conveyed to the blending tank through the first water pump 211 or by utilizing the self gravity of the sewage, the sewage concentration of the blending tank is accurately detected in real time through the sewage monitoring device 100, and blending is carried out while detection is carried out. Namely, the sewage treatment system can accurately detect the sewage concentration and can be rapidly allocated.

It should be noted that in the embodiments of the present invention, the flow direction of the wastewater in each wastewater tank (the primary slurry tank 210, the blending tank 230, and the thick slurry tank 220) may be conveyed by pumping with a water pump, or by using the gravity of the wastewater itself. In the following description, the sewage is delivered by pumping with a water pump, but it is not limited thereto, and it is understood that in some possible embodiments, the sewage may not be pumped with a water pump, i.e. the sewage is delivered to a desired sewage pool by its own weight.

In one example, as shown in fig. 1, fig. 2 and fig. 4, the raw slurry tank 210 is selectively communicated with the sewage monitoring device 100 through the first water pump 11, specifically, the raw slurry tank 210 is selectively communicated with the flow stabilizing container 10, and the sewage monitoring device 100 is further configured to detect the sewage concentration in the raw slurry tank 210. The selective communication herein means that the communication passage can be opened or closed. For example, the channel of the first water pump 211 communicating with the flow stabilizing container 10 of the sewage monitoring device 100 can be switched between on and off, i.e., the channel of the first water pump 211 communicating with the sewage monitoring device 100 may be communicated or not communicated. For example, the first water pump 211 is communicated with the sewage monitoring apparatus 100 through a first pipeline L1, an electromagnetic valve is disposed on the first pipeline L1, and the selective communication between the first water pump 11 and the sewage monitoring apparatus 100 is realized through the opening and closing of the electromagnetic valve. The invention can use electromagnetic valve to control the switch of the pipeline, and can also use pneumatic butterfly valve.

Detect the sewage in the magma pond 210 through sewage monitoring device 100, if the sewage concentration in the magma pond 210 is lower, be less than below the standard concentration, then can be continuous open first water pump 11, at the testing process, carry the sewage in the magma pond 210 to allotment pond 230.

In another example, the sewage concentration in the raw pulp tank 210 is intermittently measured using the sewage monitoring apparatus 100, and if the sewage concentration is less than the first set concentration, the tank truck can be flushed using the sewage in the raw pulp tank 210, thereby increasing the sewage concentration in the raw pulp tank 210. This reduces the use of fresh water when flushing the tanker. When the sewage concentration in the raw pulp tank 210 is equal to or higher than a set value, the tank car can be cleaned with clean water, so that the sewage concentration in the raw pulp tank 210 is reduced. Then the sewage in the primary pulp tank enters a blending tank for further blending. The concentration of the primary pulp tank is increased to be close to the set value, and then the primary pulp tank enters the blending tank, so that the sewage blending speed is increased.

In another example, the first water pump 211 is communicated with the blending tank 230 through a second pipeline L2, and a solenoid valve is disposed on the second pipeline. The electromagnetic valve on the first pipeline L1 may be opened first to detect the sewage in the raw stock tank 210, and if the standard is met, the electromagnetic valve on the first pipeline L1 is closed. Then, the electromagnetic valve on the second pipeline L2 is opened, the sewage in the primary pulp tank 210 is conveyed to the blending tank 230 through the first water pump 11, and in the process, the sewage monitoring device 100 in the blending tank 230 can be opened to continuously detect the sewage in the blending tank 230, so as to ensure that the sewage concentration meets the standard.

The following describes a specific structure of the sewage monitoring apparatus 100 and a specific principle of the sewage monitoring apparatus for accurately measuring the sewage concentration.

In one example, as shown in fig. 4 and 5, the cross-sectional area of the flow stabilizing opening 12 of the flow stabilizing container 10 is larger than that of the water outlet 22 of the weighing container 20, so that the flow of sewage flowing out of the flow stabilizing opening 12 is larger than that of the sewage flowing out of the water outlet 22, the sewage in the weighing container 20 is always in an overflow state, and the sewage level is kept stable. In another example, the flow rate of sewage at the flow stabilizing port 12 of the flow stabilizing container 10 is greater than that at the water outlet 22, so that the flow rate of sewage flowing out of the flow stabilizing port 12 is greater than that of sewage flowing out of the water outlet 22, and therefore the sewage in the weighing container 20 is always in an overflow state, and the sewage level is kept stable. In yet another example, the cross-sectional area of the flow stabilizing port 12 of the flow stabilizing container 10 is larger than the cross-sectional area of the water outlet 22 of the weighing container 20, and the flow rate of the sewage at the flow stabilizing port 12 of the flow stabilizing container 10 is larger than the flow rate of the sewage at the water outlet 22, so that the flow rate of the sewage flowing out of the flow stabilizing port 12 is larger than the flow rate of the sewage flowing out of the water outlet 22, and the sewage in the weighing container 20 is always in an overflow state, and the sewage level is kept stable. Either way, the flow rate of the sewage flowing out of the flow stabilizing port 12 can be larger than that of the sewage flowing out of the water outlet 22, so that the sewage in the weighing container 20 is always in an overflow state, and the sewage level is kept stable, and thus the sewage can be continuously and accurately measured. For example: the flow of the steady flow port or the water pump with large flow can be roughly calculated according to the section of the steady flow port 12, so that the sewage in the steady flow container is ensured to be in an overflow state. The section size of the water outlet 22 can be set according to the section size of the flow stabilizing port 12, so that the section of the water outlet 22 is slightly smaller than the section of the flow stabilizing port 12. The method ensures that the inlet flow is large and the outlet flow is small. Or valves are arranged at the water outlets of all levels, and the water flow is controlled by adjusting the size of the valves.

In some embodiments, the second water inlet 21 of the weighing container 20 may be disposed at the top of the weighing container 20, the water outlet 22 may be disposed at the bottom of the weighing container 20, the second overflow port 23 may be disposed at a side wall of the weighing container 20, the second overflow port 23 is communicated with a second overflow pipe 24, and the sewage overflowing from the second overflow port 23 flows out through the second overflow pipe 24. As an example, the weighing container 20 may have a substantially cylindrical shape, and the cylindrical weighing container 20 has an opening, which forms the second water inlet 21 of the weighing container 20 for receiving the sewage flowing out of the flow stabilizing port 12 of the flow stabilizer 10. The bottom of the cylindrical weighing container 20 forms a conical structure, a water outlet 22 is formed in the bottom of the conical structure, the water outlet 22 can be open, solid matters (adhesion matters) in sewage can be easily guided to the water outlet 22 smoothly by the conical structure, deposition is prevented, and the accuracy of sewage measurement is improved. Two second overflow ports 23 may be formed on the side wall of the cylindrical weighing container 20, and a second overflow pipe 24 is connected to each second overflow port 23. The second overflow outlet 23 may be rectangular in shape, or may be circular or other shape. The second overflow mouth 23 of rectangle compares in circular shape overflow mouth, and convenient the washing more, and the rectangle overflow mouth is followed down than circular overflow mouth along with liquid level contact range bigger, and the overflow effect is more obvious.

The inventors have found that if the sewage is deposited in the weighing container 20, the monitoring of the sewage concentration is affected, resulting in inaccurate measurement. According to the sewage monitoring device provided by the embodiment of the invention, the second water inlet 21 and the second water outlet 22 are respectively positioned at the top and the bottom of the weighing container 20, namely the second water inlet 21 and the second water outlet 22 are distributed up and down, most of sewage in the weighing container 20 can flow out through the second water outlet 22 by adjusting the size of the water outlet 22, and a small part of sewage flows out through the second overflow port 23, so that the deposition of fixed substances in the sewage is reduced or avoided to the maximum extent, the sewage in the weighing container 20 is always in a state of uniform concentration (density), and the sewage concentration obtained by final measurement and calculation is more accurate. Meanwhile, the sewage flowing in the weighing container 20 can also reduce the sewage deposition, and the sewage concentration is more uniform.

The inventors have also found that the adhesion of solid matter to the inner and outer walls of the weighing container 20 also affects the monitoring of the sewage concentration, resulting in inaccurate measurement. According to the sewage monitoring device provided by the embodiment of the invention, the second overflow pipe 24 is communicated with the second overflow port 23, so that the sewage overflowing from the second overflow port 23 flows out through the second overflow pipe 24, and the influence of the sewage overflowing to the outer wall surface of the weighing container 20 and adhering to the outer wall surface to influence the measurement precision is avoided.

In one example, the inner wall surface of the weighing container 20 is smooth, such as the weighing container 20 made of stainless steel material, to minimize or avoid solid matter in the contaminated water from adhering to the inner wall surface. In another example, the inner wall surface of the weighing container 20 may be provided with a smooth plastic plate, which also minimizes or prevents solid matter from adhering to the contaminated water. In yet another example, a release coating may also be applied to the inner wall surface of the weighing container 20.

In order to reduce the influence of the fixed matter attached or deposited to the weighing container 20 on the measurement, a vibration device may be provided on the weighing container 20 in addition to the above-described various ways, the vibration device being used to detach the solid matter attached to the surface of the weighing container 20. In the cylindrical weighing container 20, the solid substances on the surface of the weighing container 20 are separated by vibration, and the effect is more obvious.

In yet another example, a cleaning device, such as a spraying device 52, may be added at the inlet 21 of the weighing container 20, and the inner wall of the weighing container 20 is washed by the spray head of the spraying device. For example, an annular cleaning pipeline 52 may be fixedly disposed on the outer peripheral wall of the bottom of the flow stabilizing container 10, and the inner peripheral wall of the weighing container 20 is flushed by a water spraying port on the annular cleaning pipeline 52, so as to prevent the adhesion of solid matters from affecting the weighing precision of the weighing container 20. A spray head 50 may also be provided at the inlet of the flow stabilizer 10 to flush the flow stabilizer 10. Furthermore, the spraying device 50 and the annular cleaning pipeline 52 are communicated through the same clean water pipeline 51, so that the weighing container 20 and the flow stabilizing container 10 can be simultaneously washed, and the washing efficiency is improved.

In some embodiments, the flow stabilizing port 12 of the flow stabilizing container 10 is arranged at the bottom of the flow stabilizing container 10, the first water inlet 11 and the first overflow port 13 are arranged at the side wall of the flow stabilizing container 10, the first overflow port 13 is communicated with a first overflow pipe 14, and the sewage flowing out of the first overflow port 13 flows out through the first overflow pipe 14. Specifically, the flow stabilization container 10 may be disposed above the weighing container 20, for example, both the flow stabilization container 10 and the weighing container 20 are supported by a bracket. The flow stabilizing container 10 can also be cylindrical, and the bottom can also be a conical structure, so that the deposition of fixed substances in the sewage is avoided. The top of the cylindrical flow stabilizing container 10 can be of an open structure, the first water inlet 11 is arranged on the side wall of the flow stabilizing container 10, the top of the flow stabilizing container 10 is prevented from being open, and a cleaning device, such as a spraying device, is conveniently arranged.

The flow stabilizing port 12 of the flow stabilizing container 10 may be located at a position intermediate above the top opening (the second water inlet 21) of the weighing container 20, corresponding to the water outlet 22 of the weighing container 20. During the process of cleaning the flow stabilizing container 10 by the cleaning device at the top of the flow stabilizing container 10, the weighing container 20 is cleaned by the cleaning water discharged from the flow stabilizing port 12 of the flow stabilizing container 10.

In some embodiments, the weigh scale may weigh the weigh receptacle 20 and the wastewater therein via the weight monitor 25. In one example, the weighing receptacle 20 is suspended from the support frame 30 by a weight monitor 25, and weighing measurements are performed by suspending the weighing receptacle 20.

In another example, a weight monitor 25 is provided between the stand and the weighing receptacle 20, and weighing measurement is achieved by way of the weighing receptacle 20 being supported by the weight monitor 25. Specifically, can set up the three supporting shoe of equipartition at the periphery wall of weighing container 20, set up weight monitor 25 between support and every supporting shoe, weight monitor 25 through three equipartition supports the mode of weighing container 20, compares the mode that hangs and supports more steadily, weighs and measures more accurately.

The weighing of the weighing container 20 and the sewage therein according to the present invention is not limited to the above-mentioned manner, but may be measured by being supported at the bottom of the weighing container 20, or other possible manners may be possible.

In some embodiments, the first overflow pipe 14 communicated with the first overflow port 13 of the flow stabilizing container 10 and the second overflow pipe 24 communicated with the second overflow port 23 of the weighing container 20 are both communicated with the blending tank 230, the first water inlet 22 of the flow stabilizing container 10 is communicated with the blending tank 230 through the water inlet pipe 15, and the third water pump 232 connected with the water inlet pipe 15 is arranged in the blending tank 230 and used for pumping the sewage in the blending tank 230 to the flow stabilizing container 10.

Specifically, the third water pump 232 continuously pumps the sewage in the blending tank 230 into the flow stabilizing container 10 through the water inlet pipe 15, the sewage flows in from the first water inlet 22 and flows out through the flow stabilizing port 12, because the flow of the sewage flowing into the first water inlet 22 of the flow stabilizing container 10 is greater than the flow of the sewage flowing out of the flow stabilizing port 12, the sewage level in the flow stabilizing container 10 can reach the first overflow port 13 and overflow, the overflowing sewage flows back into the blending tank 230 through the first overflow pipe 14, at this time, the sewage in the flow stabilizing container 10 can be continuously in an overflow state, and the sewage flowing out of the flow stabilizing port 12 can be kept at a constant flow rate in real time. Then, sewage flowing out of the constant flow port 12 at a constant flow rate enters the weighing container 20 from the second inlet 21 and flows out of the water outlet 22 of the weighing container 20, the sewage level in the weighing container 20 can reach the second overflow port 23 and overflow out due to the fact that the flow rate of the sewage flowing out of the constant flow port 12 is larger than the flow rate of the sewage flowing out of the water outlet 22 of the weighing container 20, the overflowing sewage flows back to the blending tank 230 through the second overflow pipe 24, at the moment, the sewage in the weighing container 20 can be in an overflowing state continuously, and the sewage flowing out of the constant flow port 12 flows into the weighing container 20 at a constant flow rate, so that the sewage level in the weighing container 20 is in an almost stable state and cannot be overlooked, the sewage volume in the weighing container 20 can be kept at a constant value continuously, the measured weight of the weighing container 20 and the sewage in the overflowing state is more accurate, and the calculated sewage concentration is more accurate. Therefore, the sewage monitoring device of the present invention can accurately measure the sewage in the blending tank 230 without interruption in circulation. In addition, most of the sewage flowing into the weighing container 20 from the top second water inlet flows out from the bottom water outlet 22, a small amount of sewage overflows from the second overflow port 23, the sewage in a flowing state is hardly deposited in the weighing container 20, the concentration (density) of the sewage in the weighing container 20 is more uniform, and the measurement accuracy is further improved. In addition, in order to further avoid the influence of solid matter adhered to the inner and outer walls of the weighing container 20 on the measurement precision of the sewage concentration, the weighing container 20 adopts various modes such as a stainless steel plate, an additional smooth plastic plate or an anti-sticking layer coated on the inner wall surface to reduce the influence of the attachment of the inner wall surface of the weighing container 20 on the measurement precision to the maximum extent or adopts a mode that the overflow sewage is guided into the blending tank 230 through the second overflow port 23 and communicated with the second overflow pipe 24 to eliminate the influence of the attachment of the outer wall surface of the weighing container 20 on the measurement precision.

Furthermore, the steady flow port 12 at the bottom of the steady flow container 10 can extend into the weighing container 20 and is located below the second overflow port 23, so that when the weighing container 20 is in an overflow state, the steady flow port 12 is located below the sewage liquid level, thereby reducing the impact of sewage flowing out of the steady flow port 12 on the sewage liquid level in the weighing container 20, ensuring the sewage liquid level to be constant, and improving the sewage concentration measurement accuracy.

The blending tank 230 is connected with the clear water replenishing pipe 41 and is used for replenishing clear water into the blending tank 230 when the water amount of the blending tank 230 is insufficient.

Next, a fast sewage disposal system is described, in which the sewage allocating device and the sewage monitoring device are matched together.

In some embodiments, with reference to fig. 1, fig. 2 and fig. 3, the sewage blending device further includes: a thick liquid tank 220 and a separation device. The separation device is used for separating sewage into low-concentration sewage and high-concentration sewage. The separating device comprises a liquid inlet, a first outlet and a second outlet, sewage enters from the liquid inlet and is separated by the separating device, the sewage with low concentration is discharged from the first outlet and flows to a required sewage pool, and the sewage with high concentration is discharged from the second outlet and flows to the thick slurry pool 20. The separation device may be located at a position above the thickener tank 220. The separation device may be a system having a cyclone settling function such as a centrifuge, a cyclone, or the like to separate sewage into low-concentration sewage and high-concentration sewage. In the embodiments of the present invention, the cyclone 221 is used as an example of the separation device, but the present invention is not limited thereto. For example, a liquid inlet of the cyclone 221 is selectively communicated with the first water pump 211 in the raw stock tank 210, and an overflow port of the cyclone 221 is selectively communicated with the raw stock tank 210; and/or the overflow of the cyclone may be in selective communication with the blending tank 230. When the sewage concentration in the primary pulp tank 210 is higher than a first set concentration, the liquid inlet of the cyclone 221 is communicated with the first water pump 211, the overflow port of the cyclone is communicated with the primary pulp tank 210 and/or the blending tank 230, the sewage in the primary pulp tank 210 is conveyed to the cyclone 221 through the first water pump 211, so that the low-concentration sewage discharged from the overflow port of the cyclone 221 from the sewage in the primary pulp tank 210 is conveyed to the primary pulp tank 210 and/or the blending tank 230, and the high-concentration sewage settled from the sewage in the primary pulp tank 210 through the cyclone 221 is left in the thick pulp tank 220.

In one example, the cyclone 221 is connected to the first water pump 211 through a third line L3, a solenoid valve is disposed on the third line L3, an overflow port of the cyclone 221 is connected to the raw slurry tank 210 through a fourth line L4, and a solenoid valve is disposed on the fourth line L4. When the sewage concentration in the primary pulp tank 210 is higher than a first set concentration, the electromagnetic valve on the L3 pipeline is opened, so that the liquid inlet of the cyclone 221 is communicated with the first water pump 11; the solenoid valve on the fourth pipeline L4 is opened to communicate the overflow port of the cyclone 221 with the raw pulp tank 210, and the sewage in the raw pulp tank 210 is transferred to the cyclone 221 by the first water pump 211, so that the low-concentration sewage discharged from the sewage in the raw pulp tank 210 through the overflow port of the cyclone 221 is returned to the raw pulp tank 210, and the concentration of the sewage in the raw pulp tank 210 is adjusted. Meanwhile, the electromagnetic valve on the first pipeline L1 may be opened, so as to detect the sewage in the primary pulp tank 210 until the sewage in the primary pulp tank 210 is lower than a first set concentration value.

In another example, the overflow port of the cyclone 221 is further communicated with the blending tank 230 through a fifth pipeline L5, and a solenoid valve is disposed on the fifth pipeline L5. Similarly, when the sewage concentration in the primary pulp tank 210 is higher than a first set concentration, the solenoid valve on the third pipeline L3 is opened, so that the liquid inlet of the cyclone 221 is communicated with the first water pump 11; the electromagnetic valve on the fifth pipeline L5 is opened to communicate the overflow port of the cyclone 221 with the blending tank 230, and the sewage in the raw slurry tank 210 is delivered to the cyclone 221 by the first water pump 211, so that the low-concentration sewage discharged from the sewage in the raw slurry tank 210 through the overflow port of the cyclone 221 is delivered to the blending tank 230, and the concentration of the sewage in the blending tank 230 is blended. Meanwhile, the sewage monitoring device 100 communicated with the blending tank 230 can be started to continuously detect the sewage in the blending tank 30.

It can be understood that the electromagnetic valve on the fifth pipeline L5 is opened to communicate the overflow port of the cyclone 221 with the blending tank 230, and the electromagnetic valve on the fourth pipeline L4 is also opened to communicate the overflow port of the cyclone 221 with the raw slurry tank 210, that is, the first water pump 211 is used to deliver the sewage in the raw slurry tank 210 to the cyclone 221, so that the low-concentration sewage discharged from the overflow port of the cyclone 221 from the sewage in the raw slurry tank 210 is delivered to the blending tank 230 and the raw slurry tank 210, and the sewage in the raw slurry tank 210 is blended while the concentration of the sewage in the blending tank 230 is blended.

Further, as shown in fig. 2 and 3, the sewage blending device further includes a settling vessel 222 (a concentration settling tank), and the settling vessel 222 is provided with a top inlet 2221, a bottom outlet 2222, and a discharge port 2223 between the top inlet and the bottom outlet. The overflow port of the cyclone 221 is communicated with the top inlet 2211, the bottom outlet 2222 is communicated with the thick slurry tank 220, and the discharge port 2223 is communicated with the raw slurry tank 210 and/or the blending tank 230. The settling container 222 is used for further settling the sewage discharged from the overflow port of the cyclone 221 to perform liquid-solid separation, so that the larger-particle sewage (sewage with higher concentration) is located at the bottom of the settling container 222 and discharged from the bottom outlet 2222 into the thick slurry tank 220, and the cleaner sewage (sewage with lower concentration) is delivered from the discharge port 2223 to the primary slurry tank 210 and/or the blending tank 230, thereby performing sewage blending on the primary slurry tank 210 and/or the blending tank 230.

It will be appreciated that in some of the examples described above and below, the effluent settled and separated via the overflow of the cyclone 221 may be directly sent to the primary pulp tank 210 and/or the blending tank 230, or may be settled again in the settling vessel 222 and then sent to the primary pulp tank 210 and/or the blending tank 230.

In some embodiments, a third liquid level detection device is disposed in the blending tank 230 for detecting the sewage level in the blending tank 230. The third liquid level detection means may be, for example, a liquid level sensor. When the sewage concentration in the raw pulp tank 210 is higher than the first set concentration and the sewage level in the blending tank 230 is higher than the third set level, it indicates that the liquid level in the blending tank 230 is higher, at this time, the liquid inlet of the cyclone 221 is communicated with the first water pump 211, the overflow port of the cyclone 221 is communicated with the raw pulp tank 210, and the sewage in the raw pulp tank 210 is conveyed to the cyclone 221 through the first water pump 211, so that the low-concentration sewage discharged from the overflow port of the cyclone 21 from the sewage in the raw pulp tank 10 is conveyed to the raw pulp tank 210. That is to say, the sewage concentration in the primary pulp tank 210 is high, the liquid level of the blending tank 230 is high, the blending tank 230 does not need to be filled with sewage, the high-concentration sewage in the primary pulp tank is settled and separated, and the low-concentration sewage is returned to the primary pulp tank 210 through the cyclone 221, so that the sewage in the primary pulp tank 210 is blended.

When the sewage concentration in the primary pulp tank 210 is higher than the first set concentration and the sewage level in the blending tank 230 is lower than the third set level, which indicates that the liquid level in the blending tank 230 is lower, at this time, the liquid inlet of the cyclone 221 is communicated with the first water pump 211, the overflow port of the cyclone 221 is communicated with the blending tank 230, and the sewage in the primary pulp tank 210 is conveyed to the cyclone 221 through the first water pump 211, so that the low-concentration sewage discharged from the overflow port of the cyclone 221 from the sewage in the primary pulp tank 210 is conveyed to the blending tank 230. That is to say, the sewage concentration in the primary pulp tank 210 is high, the liquid level of the blending tank 230 is high, the blending tank 230 does not need to be filled with sewage, the high-concentration sewage in the primary pulp tank is settled and separated, and the low-concentration sewage is returned to the primary pulp tank 210 through the cyclone 221, so that the sewage in the primary pulp tank 210 is blended.

In some embodiments, a first liquid level detection device is further disposed in the raw slurry tank 210 for detecting a sewage liquid level in the raw slurry tank 210. The first level detection means may be, for example, a level sensor. When the sewage concentration in the primary pulp tank 210 is higher than a first set concentration and the sewage level in the primary pulp tank 210 is higher than a first set liquid level, the liquid inlet of the cyclone 221 is communicated with the first water pump, the overflow port of the cyclone 21 is communicated with the blending tank 230, and the overflow port of the cyclone 221 is not communicated with the primary pulp tank 210, so that the low-concentration sewage discharged from the sewage in the primary pulp tank 210 through the overflow port of the cyclone is conveyed to the blending tank 230.

When the sewage concentration in the raw pulp tank 210 is high and the sewage level is also high, the sewage with the high concentration in the raw pulp tank 210 is settled through the cyclone 221 to obtain the sewage with the low concentration, and then the sewage is conveyed into the blending tank 230 to blend the sewage in the blending tank 230.

In some embodiments, the thick stock tank 220 is provided with a second water pump 223, and the thick stock tank 220 is selectively communicated with the blending tank 230 through the second water pump 223. When the sewage monitoring device 100 detects that the sewage concentration in the blending tank 230 is lower than the set standard concentration, the second water pump 223 transfers the sewage in the thick liquid tank 220 to the blending tank 230. Illustratively, the second water pump 223 is communicated with the blending tank 230 through a sixth pipeline L6, and an electromagnetic valve is disposed on the sixth pipeline L6. When the sewage monitoring device 100 detects that the sewage concentration in the blending tank 30 is lower than the set standard concentration, the electromagnetic valve on the sixth pipeline L6 is opened, and the sewage in the thick slurry tank 220 is conveyed to the blending tank 230 through the second water pump 223, so that the high-concentration sewage in the thick slurry tank 20 is utilized, and the zero discharge of the sewage is realized.

In some embodiments, the slurry tank 220 is provided with a second water pump 223, the slurry tank is also in selective communication with the sewage monitoring device 100 through the second water pump 223, specifically, the slurry tank is also in selective communication with the flow stabilizing container 10 through the second water pump 223, and the sewage monitoring device is also used for detecting the sewage concentration in the slurry tank 220. Illustratively, the second water pump 223 communicates with the sewage monitoring apparatus 100 through a seventh pipeline L7, and an electromagnetic valve is disposed on the seventh pipeline L7. The second water pump 223 is selectively connected to the liquid inlet of the cyclone 221. Illustratively, the second water pump 223 is communicated with the liquid inlet of the cyclone 221 through an eighth pipeline L8, and an electromagnetic valve is disposed on the eighth pipeline. When the sewage concentration in the thick slurry tank 220 is lower than the second set concentration, the second water pump 223 is communicated with the liquid inlet of the cyclone 221 (for example, the electromagnetic valve on the eighth pipeline L8 is opened), the overflow port of the cyclone 221 is communicated with the blending tank 230 and/or the raw slurry tank 210, the sewage in the thick slurry tank 220 is conveyed to the cyclone 221 through the second water pump 223, so that the low-concentration sewage discharged from the sewage in the thick slurry tank 220 through the overflow port of the cyclone 221 is conveyed to the blending tank 230 and/or the raw slurry tank 210, and the high-concentration sewage settled by the sewage in the thick slurry tank 220 through the cyclone 221 is left in the thick slurry tank 220. When the sewage concentration in the thick stock tank 220 is higher, the sewage concentration is reduced by the cyclone 221 and then enters the blending tank 230 and/or the primary stock tank 210, so that the sewage concentration in the blending tank 230 and/or the primary stock tank 210 can be blended.

In some embodiments, the thickener tank 220 is provided with a second water pump 223, and the second water pump 223 is selectively communicated with the liquid inlet of the cyclone 221. A second liquid level detection device is arranged in the thick liquid tank 220 and used for detecting the sewage liquid level in the thick liquid tank 220. The second liquid level detection means may be, for example, a liquid level sensor. When the sewage level in the thick liquid tank 220 is higher than the second set liquid level, the liquid inlet of the cyclone 221 is communicated with the second water pump 223, and the overflow port of the cyclone 221 is communicated with the blending tank 230, so that the low-concentration sewage discharged from the sewage in the thick liquid tank 220 through the overflow port of the cyclone 21 is conveyed to the blending tank 230. And/or when the sewage level in the thick slurry tank 220 is higher than a second set liquid level and the sewage level in the primary slurry tank 210 is lower than a first set liquid level, the liquid inlet of the cyclone 221 is communicated with the second water pump 223, and the overflow port of the cyclone 221 is communicated with the primary slurry tank 210, so that the low-concentration sewage discharged from the sewage in the thick slurry tank 220 through the overflow port of the cyclone 221 is conveyed to the primary slurry tank 210.

In some embodiments, the blending tank 230 is provided with a fourth water pump 233, and the fourth water pump 233 is selectively communicated with the liquid inlet of the cyclone 221. Illustratively, the fourth water pump 233 is connected to the liquid inlet of the cyclone 221 through a ninth pipeline L9, and an electromagnetic valve is disposed on the ninth pipeline. When the concentration in the blending tank 230 is higher than the predetermined standard concentration, the third water pump 232 is communicated with the liquid inlet of the cyclone 221 (for example, the electromagnetic valve on the ninth pipeline L9 is opened), and the overflow port of the cyclone 221 is communicated with the raw slurry tank 210 and/or the blending tank 230, so that the low-concentration sewage discharged from the overflow port of the cyclone 21 in the blending tank 230 is delivered to the raw slurry tank 210 and/or the blending tank 230.

In some embodiments, a cleaning pipeline may be introduced into the blending tank 230 and/or the sewage monitoring apparatus 100, and the blending tank 230 and/or the sewage monitoring apparatus 100 may be cleaned by clean water.

In summary, the sewage treatment system of the present invention can accurately monitor the sewage concentration in the blending tank 230 in real time through the sewage monitoring device 100, and is also beneficial to the sewage monitoring device 100 to monitor the sewage concentrations in the raw slurry tank 210 and the thick slurry tank 220, and the sewage concentration values in the sewage tanks are rapidly blended according to the sewage concentration values in the sewage tanks. Further, through a separating device (such as a cyclone 221), the sewage in the primary pulp tank 210, the thick pulp tank 220 and the blending tank 230 can be separated into low-concentration sewage and high-concentration sewage, the high-concentration sewage is left in the thick pulp tank 220, and the low-concentration sewage is conveyed according to needs, such as the primary pulp tank 210 and the blending tank 220 are conveyed, that is, the cyclone 221 can be used for blending and diluting the sewage in the primary pulp tank 210, and the sewage in the blending tank 220 can be blended and diluted, and the sewage monitoring device 100 is matched for accurate measurement, so as to achieve the purpose of blending the required sewage concentration.
