Biological cage integrated pilot plant

technical field

The invention relates to a sewage treatment system, in particular to an integrated pilot test device for biological cages.

Background technique

At present, the advanced technologies for sewage treatment at home and abroad mainly include biological methods, chemical methods and physical methods. In the treatment of a large amount of industrial sewage or urban sewage, the biological method is the most adopted method. The principle of the biological method is to use microorganisms to decompose organic matter, and supplement the oxygen required for microbial respiration and decomposition of organic matter through mechanical oxygenation.

In the prior art, a biological tumbler is used to purify sewage. The biological tumbler is equipped with biological fillers, and the microorganisms on the biofilm on the surface of the biological fillers have the effect of treating pollutants in the sewage. The problem with the prior art is that the biological fillers are gradually piled up in one place during the rotation process, resulting in insufficient contact between the biological fillers and the pollutants in the sewage.

Contents of the invention

The invention provides a device for fully contacting and reacting biological filler in a biological rotating cage with sewage.

The basic solution provided by the present invention is: a biological tumbler integrated pilot test device, including a sewage inlet pipe connected to a sewage water source, a sewage water pump for pumping out sewage, a regulating tank for storing sewage, a biological tumbler reactor for purifying sewage, a secondary sedimentation tank, The dosing box connected to the secondary settling tank and the sludge drying tank connected to the secondary settling tank;

The bio-rotating cage reactor includes a water inlet pump, a reaction tank, a biological rotating cage, a driving mechanism for driving the biological rotating cage, and a water inlet pipe and an outlet pipe connected to the reaction tank. The water port is connected to the water inlet pipe of the reaction tank, and the water outlet pipe of the reaction tank is connected to the secondary sedimentation tank;

The upper end of the reaction tank is open, and the driving mechanism includes a motor and a transmission assembly. The motor is connected to the input end of the transmission assembly, and the output end of the transmission assembly is connected to the biological rotating cage. Partition boards, some radial partitions and some spherical biological fillers, the biological cage is divided into arc-shaped side walls and two plate-shaped side plates, and a number of permeable holes are opened on the side walls and side plates. The partition is a square plate, the inner side of the axial partition is fixed on the rotating shaft, the outer side of the axial partition is fixed on the inner wall of the side wall of the cage, and the two ends of the axial partition are respectively connected to the side wall; The radial partition is an annular plate, the inner end of the radial partition is connected to the rotating shaft, the outer end of the radial partition is connected to the inner wall of the side wall, and the radial partition is axially distributed along the rotating shaft; The interior of the cage is divided into several compartments by the partition plate and the radial partition plate, and the biological filler is placed in the compartment;

The bottom of the secondary sedimentation tank is provided with a sludge discharge pipe connected to the sludge drying tank;

The sludge drying tank is provided with a filter layer, and the bottom of the filter layer is provided with a sewage pipe connected to the regulating tank.

Principle: The water quality and quantity of the homogenized sewage in the adjustment tank, because the sewage flowing into the sewage treatment system is not always uniform, for example, the water volume is small in the early morning, the water consumption is large during the time period before and after dinner, cooking, washing, etc., and the water quality parameters change It is also relatively large, which requires a pool to temporarily store the inflowing water in it to homogenize the water quality and reduce the impact on the sewage treatment system. The main function of the biological cage is to remove pollutants in sewage through biochemical reactions. In order to speed up the biochemical reaction, let the spherical biological filler with microorganisms be in contact with the sewage, through the rotation of the biological cage, the biological filler will roll, so that the sewage, air and organisms can fully contact, provide conditions for the biochemical reaction, and use the biochemical reaction of microorganisms , such as nitrification, denitrification and other biochemical reaction processes to remove pollutants in sewage. The axial partition plate makes the biological filler roll up and down, and can be separated from the water surface, and the radial partition plate prevents the biological filler from sliding in the axial direction, so that the biological filler is evenly distributed. The sewage treated by the biological cage enters the secondary sedimentation tank. In the secondary sedimentation tank, the sewage is allowed to stand still to settle the sludge, and the sedimentation of the sludge is promoted by adding medicine. These sludges are deposited and removed, and finally the qualified water is discharged. The sludge that has been settled in the secondary settling tank and discharged from the bottom also contains a large amount of water. In order to fully treat it and reduce the amount of sludge disposal, sludge drying is required to separate the sewage contained in the sludge and return it to the regulating tank for recycling treatment, leaving only the dried sludge.

Compared with the prior art, the advantages of this solution are:

1. Efficient treatment of sewage. After the treatment of biological cages and secondary sedimentation tanks, pollutants in sewage can be effectively treated.

2. There are axial partitions and radial partitions in the biological cage. On the one hand, the biological filler is evenly distributed, and the contact area between the biological filler and the sewage is increased. On the other hand, the biological filler can be separated from the sewage environment and Exposure to air accelerates biochemical reactions.

Further, the bottom of the reaction tank is inclined, and the lowest part of the reaction tank is connected with a sludge discharge pipe, and the sludge discharge pipe is connected with a solenoid valve. Beneficial effects: In this design scheme, considering the rotation of the biological cage, the sedimentation performance in the tank of the biological cage reactor is poor, so the slope is increased to 10%. Setting the bottom slope, on the one hand, can make the biological cage have the basic sedimentation function and reduce the burden on the secondary sedimentation tank; At the same time, it can exert the anaerobic digestion function of anaerobic bacteria in the sludge and reduce the overall discharge of sludge.

Further, the filling rate of the biological filler in the biological cage is 68%-72%. Beneficial effects: On the one hand, the filling of high specific surface area fillers greatly increases the surface area of the biological cage for microorganisms to attach; on the other hand, the filling rate prevents the biological filler in the biological cage from being stuck due to too much Turning, but with the running of the biological cage, it is constantly rolling in it, and it is in a fluidized state. The fluidized state of the biofiller not only improves the efficiency of the contact between the air and the biofilm, but also makes the aged and poorly adhered biofilm fall off through the collision between the biofillers, thus carrying out the "survival of the fittest" in the state of the biofilm. Increases the activity of biofilms on biomedia.

Further, there is a regulating pipe between the water outlet of the water inlet pump and the reaction tank, the regulating pipe is provided with an electronic flow meter and an electric valve, and the bio-cage reactor is provided with a return pressure divider, which includes a return pipe and a valve arranged in the return pipe. The cut-off valve, the return pipe is connected to the regulating pipe, and the return pipe is connected to the regulating pool. Beneficial effects: because it is a pilot plant, the processing capacity of the device is limited, and the lowest power of the water inlet pump exceeds the processing capacity of the device. At this time, the stop valve and the electric valve are opened, and the electric valve restricts the flow entering the regulating pipe, and the excess flow passes through The shut-off valve enters the return pipe to achieve the effect of adjusting the flow in the pipe in time.

Further, the regulating tank is provided with a shielding box, the water inlet of the water inlet pump is set in the shielding box, the side wall of the shielding box is provided with an overflow port, and the shielding box is set in the upper part of the regulating pool. Beneficial effect: the slightly clear water in the upper layer of the regulating pool enters the shielding box through the overflow port, and the shielding box blocks the sludge in the regulating pond, so as to prevent the water inlet pump from sucking too much sludge and affecting the service life.

Further, the filter layer is a quartz sand filter layer. Beneficial effects: the middle of the sludge drying tank is covered with a filter layer such as quartz sand, and the sludge flowing out of the secondary settling tank is filtered through the filter layer of quartz sand, the sewage is filtered, and the sludge is intercepted, thereby realizing the separation of mud and water, and the sludge is dried change.

Further, the reaction tank is provided with an overflow prevention pipe above the water outlet pipe. Beneficial effects: when the outlet pipe cannot discharge the treated water in time, the high water level in the reaction tank will affect the contact between the biological filler in the cage and the air, so the anti-overflow pipe is set to raise the reaction tank in time when the water outlet speed of the outlet pipe is insufficient water outlet speed.

Further, the regulating tank is provided with a sewage sampling mechanism, and the sewage sampling mechanism includes a base fixed above the regulating pond, a hoist, a connecting rope, a fixed pulley, a sampling pipe, a sliding sleeve, a sampling valve installed at the bottom of the pond, and a connecting The sampling box of the sampling valve, one end of the connecting rope is connected to the winch, the middle part of the connecting rope goes around the fixed pulley, the other end of the connecting rope is connected to the sampling tube, and the outer wall of the sampling tube is slidably connected to the inner wall of the sliding sleeve. The sliding sleeve is fixedly connected to the base. When sampling, the lower end of the sampling tube extends into the adjustment tank. The lower end of the sampling tube is inclined with the left lower and the right higher; the sampling valve includes a left valve plate and a right valve plate. , the left valve plate and the right valve plate are both pivotally connected to the bottom of the regulating pool through a torsion spring. The contact is divided into a driving end and a driven end. When it is opened, the lower end of the sampling tube pushes the driving end downward. The bottom of the adjustment pool is provided with a rotating groove for the driving end to rotate and a communication hole for the sampling water to pass through. The lower end of the communication hole communicates with the sampling box.

Beneficial effects: when testing water quality, it is necessary to extract sewage from the regulating pool and detect the content of pollutants. However, due to too many substances in the sewage, the sewage will stratify itself after standing for a period of time, and the sewage is simply extracted at one height or one place Water samples cannot represent the overall situation of sewage. The conventional idea is to mix the sewage in the regulating tank and then collect the sewage water samples, so that the uniformly mixed sewage can be collected. However, because the regulating tank will collect a large amount of sewage and leave it still, using a stirring device to stir the sewage will consume too much energy and the cost will be too high. In the sewage sampling process of this scheme, the winch rotates, the connecting rope is loose, the sampling pipe slides down under the action of its own weight, the sampling pipe slides vertically under the restriction of the sliding sleeve, the left side of the lower end of the sampling pipe is lower, and the left valve plate is first pushed Drive end, then the right side of the lower end of the sampling tube pushes the drive end of the right valve plate, the left valve plate and the right valve plate are tilted, the sewage enters the communication hole through the opened sampling valve, and then enters the sampling box through the communication hole. The sewage entering the sampling tank contains sewage at all vertical heights, so after mixing it can be very close to the situation after all the water in the pool is fully mixed. When the sewage flows into the sampling box, it will be mixed to a certain extent. When the mixing is not sufficient, a small stirring device can be installed in the sampling box, because it is only a small amount of stirring, so the energy consumption is less. When the sampling tube was lifted, the left valve plate and the right valve plate respectively re-closed the communicating hole under the action of the torsion spring.

The sludge drying tank 7 is provided with a filter layer, and the bottom of the filter layer is provided with a sewage pipe connected to the regulating tank 3 . The filter layer is a quartz sand filter layer.

There is a sewage sampling mechanism in the regulating tank 3, and the sewage sampling mechanism includes a base fixed on the top of the regulating pond 3, a hoist 91, a connecting rope 92, a fixed pulley, a sampling pipe 93, a sliding sleeve 94, and a sampling valve installed at the bottom of the pond 419 And the sampling box 95 that communicates with the sampling valve, one end of the connecting rope 92 is connected to the winch 91, the middle part of the connecting rope 92 is bypassed by the fixed pulley, the other end of the connecting rope 92 is connected to the sampling tube 93, and the outer wall of the sampling tube 93 is slidably connected to the sliding sleeve 94. The inner wall and the sliding sleeve 94 are fixedly connected to the base. When sampling, the lower end of the sampling tube 93 is inserted into the adjustment pool 3. The lower end of the sampling tube 93 is inclined to the left and the right is high; the sampling valve includes a left valve plate 961 and a right valve plate. Plate 962, left valve plate 961 and right valve plate 962 are all pivotally connected to the pool bottom 419 of regulating pool 3 by torsion springs.

The communication hole 97 through which water passes, and the lower end of the communication hole 97 communicates with the sampling box 95 .

In the implementation process, as shown in Figure 1, the sewage water pump 2 starts to pump sewage from the sewage channel through the sewage water inlet pipe 1, injects the sewage into the regulating tank 3 and stands for a period of time, the sewage water quality is homogenized, and the water level in the regulating pond 3 rises. The water in the upper layer flows into the shielding box 310 through the overflow port 311 . Start the water inlet pump 312 in the shielding box 310, and the sewage flows into the biological cage reactor 4 through the electric valve 313 and the electronic flow meter 314. Because this scheme is a pilot test structure, it needs to be adjusted, so the sewage treatment capacity is limited. When the sewage flow rate in the tumbler reactor 4 is too large, open the shut-off valve and adjust the electric valve 313, and the excess sewage will flow back into the shielding box 310 through the return pipe 315.

As shown in FIG. 2 , when the sewage enters the bio-cage reactor 4 , the water enters the reaction tank 430 through the water inlet pipe 431 . The motor starts, and the motor drives the rotating shaft 412 to rotate through the belt transmission group, and the rotating shaft 412 rotates to drive the biological cage to rotate thereupon. At the same time, sewage enters the reaction tank 430 from the water inlet pipe 431, first enters the leftmost compartment 418 through the permeable holes on the side wall 415 and the side plate 416, and contacts with the spherical biological filler in the compartment 418. At the same time, through the rotation of the biological cage, the axial partition plate 414 shown in Figure 3 continuously drives the biological filler to rotate, so that the sewage, air and biological filler are fully contacted, providing conditions for the biochemical reaction between the biological filler and the pollutants in the sewage , using microbial biochemical reactions, such as nitrification, denitrification and other biochemical reaction processes to remove pollutants in sewage. During the process of sewage flowing from the left water inlet pipe 431 to the right water outlet pipe 432, the sewage will flow through the permeable holes on the side wall 415, the side plate 416, the radial partition plate 413 and the axial partition plate 414. This process is accelerated during the rotation of the biological tumbler. A part of the sludge in the sewage will be deposited in the reaction tank 430, and most of the reacted water will flow out through the outlet pipe 432. If the equivalent is accumulated too much, when the liquid level reaches the anti-overflow pipe 433, the anti-overflow pipe 433 will also prevent the overflow pipe 433 from overflowing as soon as possible. The water is drained to avoid contacting the biological filler with air in the isolation chamber above the rotating shaft 412 . Simultaneously, the silt settled at the bottom 419 of the reaction tank 430 will slide down to the bottom of the slope on the right side along the slope of the bottom 419 of the pond.

At this time, the sewage contains suspended sludge (sludge produced by microbial growth), which needs to be precipitated and removed before the water can be discharged up to the standard. In the secondary settling tank 5, the sewage is allowed to stand still to settle the sludge, and the sedimentation of the sludge is promoted by adding medicine. The clear water after settling in the secondary settling tank 5 is discharged into the river water through the clear water drain pipe to complete the whole treatment of the sewage.

Simultaneously, the sludge in the secondary settling tank 5 needs to be discharged, and the sludge settled in the secondary settling tank 5 and discharged from the bottom also contains a large amount of water. In order to fully treat it and reduce the amount of sludge disposal, sludge drying is required. A filter layer such as quartz sand is laid in the middle of the sludge drying tank 7, and the sludge flowing out of the secondary sedimentation tank 5 is passed through the filter layer of quartz sand. Filtration, the sludge is intercepted, the sewage contained in the sludge is separated, and returned to the regulating tank 3 for circulation treatment, leaving only the dried sludge. Thereby realizing mud-water separation and sludge drying.

The process of sewage sampling in this scheme, as shown in Fig. 4, Fig. 5 and Fig. 6, the winch 91 rotates, the connecting rope 92 becomes loose, the sampling pipe 93 slides under the action of its own weight, and the sampling pipe 93 is vertically vertical under the restriction of the sliding sleeve 94. Sliding, the upper end of the sampling pipe 93 has air holes. During the sliding process of the sampling pipe 93, the sewage in the scope of the sampling pipe enters the range of the sampling pipe 93, and the left side of the lower end of the sampling pipe 93 is lower. First, the driving of the left valve plate 961 is pushed end, and then the right side of the lower end of the sampling pipe 93 pushes the driving end of the right valve plate 962, the left valve plate 961 and the right valve plate 962 are tilted up, and the sewage enters the communication hole 97 through the opened sampling valve, and then enters through the communication hole 97. In the sampling box 95. The sewage entering the sampling box 95 includes sewage at all heights vertically, so after mixing, it can be very close to the situation after all the water in the pool is fully mixed. Sewage can be mixed to a certain extent when flowing into the sampling box 95. When the mixing is insufficient, a small-scale stirring device can be set in the sampling box 95, because it is only a small amount of stirring, so the energy consumption is less. When the sampling tube 93 is lifted, the left valve plate 961 and the right valve plate 962 respectively re-close the communication hole 97 under the action of the torsion spring.
