Detailed Description
Examples, see fig. 1 to 4: the urban comprehensive sewage treatment system is used for purifying sewage in the river channel 100. The left part of the river 100 has a bank 200, and a sewage pipe 300 is provided in the bank 200, and urban sewage is discharged from the inside of the sewage pipe 300 to the inside of the river 100 from left to right. Obviously, the right part of the river 100 is necessarily provided with a bank, and this embodiment will be described with a bank at the left part only.
Specifically:
the urban comprehensive sewage treatment system also comprises a primary treatment unit, a forced treatment unit and a remediation unit.
The primary processing unit is provided with a water ramp 410, a first temporary storage channel 420, a communication channel 430 and a second temporary storage channel 440 in sequence from left to right. That is, the municipal sewage flowing out of the sewer 300 passes through the water ramp 410, the first temporary storage channel 420, the communication channel 430, and the second temporary storage channel 440 in this order, and then flows into the river 100.
The water ramp 410 is vertically low on the left and right and the left side of the water ramp 410 is connected to the right side of the bank 200. The water ramp 410 is paved with a mixed layer 412 formed by mixing a plain soil layer 411, yellow mud and broken stone and a concrete layer 413 from top to bottom. Wherein the proportion of yellow mud in the mixing layer 412 is preferably higher than the proportion of crushed stone. The concrete layer 413 is integrally formed with a plurality of cement chamfers 4131 extending upward so that the upper ends thereof protrude above the plain soil layer 411. The cement chamfer 4131 may be multi-channel and arranged from left to right. The cement chamfer 4131 is inclined at the upper side to the left and the lower side to the right. An aeration device 4132 is provided to the left of the root of each cement chamfer 4131 as close to that cement chamfer 4131 as possible. Thus, the aeration effect can be improved by times through testing. Meanwhile, the sewage can be primarily purified by each layer of the water slope 410, and the repeated washing and purification of the sewage are equivalent to the cement chamfering 4131. The first aquatic plant 4111 is planted in the plain soil layer 411. The first aquatic plant 4111 may employ a common water-border plant. The root systems of the first aquatic plants 4111 can penetrate into the mixed layer 412, so that the root systems can be well planted, and the root systems can also be used for purifying sewage.
The first temporary storage channel 420 is provided with a water spraying pipe 421. The water inlet of the water spraying pipe 421 is located at the bottom of the first temporary storage channel 420, the water spraying port of the water spraying pipe 421 is upward, and the sprayed water is sprayed to the left part of the water ramp 410. That is, the sewage is replenished with oxygen in the air. Meanwhile, in order to facilitate the removal of impurities, the upper portion of the first temporary storage channel 420 may be covered with a gauze, and the water inlet of the water spray pipe 421 is wrapped by the gauze. Obviously, the spout 421 is provided with a pressurizing pump.
The communication channel 430 communicates the first temporary storage channel 420 with the second temporary storage channel 440. The communication channel 430 is provided with a clamping groove 431, a frame 432 capable of being taken out is clamped in the clamping groove 431, the frame 432 is provided with a biological membrane 433, and the biological membrane 433 can be a common water-permeable ecological membrane. That is, the biofilm 433 purifies water flowing through the communication channel 430 again, and after a while, the biofilm 433 can be conveniently replaced.
The second temporary storage channel 440 is provided with a plurality of bacteria-throwing nozzles 441, and the bacteria-throwing nozzles 441 are connected with a bacteria box (not shown in the figure), and photosynthetic bacteria and/or nitrifying bacteria are arranged in the bacteria box. Meanwhile, the bacteria-feeding nozzle 441 is provided with a switch (not shown) controlled by a first detecting member (not shown) located in the first temporary storage channel 420. That is, the switch is opened to input fungus into the second temporary storage canal 440 for biological purification only when the first detecting means detects that the sewage quality in the first temporary storage canal 420 is still poor and does not reach the set standard. To keep the sewage in the second temporary storage channel 440 for a sufficient time, the second temporary storage channel 440 is at least 2 times as large in volume as the first temporary storage channel 420.
The forced treatment unit includes a number of open-topped sumps 510. That is, the water flowing out of the second temporary storage channel 440 flows into the sump 510. Sump 510 may be cylindrical. A return pipe 511 is provided in the sump 510. The water outlet of the return pipe 511 is connected to an advanced municipal sewage treatment unit 512, and the quality of the water treated by the advanced municipal sewage treatment unit 512 reaches the A standard of the primary standard of reclaimed water. Meanwhile, the water return pipe 511 is provided with a water pump 5111, and the water pump 5111 is controlled by a second detecting component located in the second temporary storage channel 440. That is, if the second detecting means detects that the water quality in the second temporary storage channel 440 meets the requirement, the water in the sump 510 is directly discharged into the river 100; if the second detecting means detects that the water quality in the second temporary storage channel 440 cannot meet the requirement, the water pump 5111 is started, the water in the water storage pit 510 enters the municipal sewage advanced treatment unit 512 for treatment through the water return pipe 511, and the water treated by the municipal sewage advanced treatment unit 512 can directly flow into the river 100. The advanced municipal sewage treatment unit 512 may be a common device, and will not be described herein.
The remediation unit includes a plurality of water replenishment pumps 610, the water replenishment pumps 610 are located in deep wells, and water outlets of the water replenishment pumps 610 are located in the river 100. That is, when the water quality in the river 100 is extremely poor and difficult to treat, clean water can be introduced into the river 100, so that the effect of dilution is achieved, and well water is mixed with sewage at a high cost, but beneficial bacteria, microorganisms, and the like can be added to the sewage, so that the river can be purified again more quickly.
Further, the following is said:
the bottom of the river 100 has a silt layer 110 of 200-300 mm. Volcanic rock fragments 111 are mixed in the silt layer 110, and second aquatic plants 112 are planted in the silt layer 110. The second aquatic plant 112 may employ conventional nutrient and deepwater plants.
Therefore, the urban comprehensive sewage treatment system adopts a mode of combining a plurality of treatment modes, and not all the treatment modes act simultaneously, but are matched with each other selectively, so that the urban comprehensive sewage treatment system not only achieves better sewage treatment capacity, but also saves energy and resources.
Optimizing:
the aeration device 4132 includes an aeration tube. The aeration tube has a double-layer structure so as to have an inner tube 41321 and an outer tube 41322, and both the inner tube 41321 and the outer tube 41322 are connected with an air source. The pressure of the gas in the inner tube 41321 is greater than the pressure of the gas in the outer tube 41322, the upper portion of the inner tube 41321 is provided with an inner hole 413211, the lower portion of the outer tube 41322 is provided with an outer hole 413221, and the aperture of the outer hole 413221 is smaller than the aperture of the inner hole 413211. Thus, in a complex sewage environment, foreign substances are not easy to enter the aeration pipe, and aeration holes including the inner holes 413211 and the outer holes 413221 are not easy to be blocked, so that an excellent aeration effect can be achieved. Compared with a common single-tube type aeration device, the maintenance rate can be reduced by 30%, and the aeration effect is obviously improved.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes using the descriptions and drawings of the present invention or directly or indirectly applied to other related technical fields are included in the scope of the invention.
