Description

A sewage treatment equipment with multi-stage filtration function

Technical Field

The invention relates to the technical field of sewage treatment, and in particular to sewage treatment equipment with a multi-stage filtering function.

Background Art

With the rapid development of human economy, environmental pollution is becoming more and more serious, among which water pollution is also becoming more and more serious, especially eutrophication, which seriously affects the water ecological environment. Eutrophication is a water pollution phenomenon caused by excessive content of plant nutrients such as nitrogen and phosphorus. The municipal sewage treatment system collects sewage within the designated discharge range and transports it to the sewage treatment plant through the pipe network system for unified and centralized treatment. For areas with relatively small sewage volume and remote locations, such as rural areas, tourist resorts, etc., decentralized treatment is more economical and effective. At this time, integrated sewage treatment equipment is often required to treat the sewage.

Chinese patent application number 202211214450.1 discloses an integrated village sewage treatment device, including a box body, which is connected with an inlet pipe, a regulating tank, a first water pipe, a sedimentation tank, a second water pipe, an anaerobic tank, a third water pipe, an aerobic tank, a fourth water pipe, a membrane treatment tank, a clean water tank and a drain pipe from left to right, and a water collecting pipe and a mounting frame are arranged on the membrane treatment tank, and a plurality of membrane assemblies are arranged in an array on the mounting frame, and the membrane assembly includes a mounting frame and a filter membrane, and the filter membrane is arranged on the mounting frame, and the mounting frame is detachably mounted on the mounting frame, and the filter membrane, the mounting frame and the filter membrane are arranged on the mounting frame. The mounting frame cooperates to form a water filter cavity, and the mounting frame is provided with a water filter pipe which is connected to the water filter cavity, and the water filter pipe is led out from the bottom end of the membrane treatment tank. Although the prior art can separate and filter the biologically treated sewage through the membrane assembly, it only separates and filters the sewage through the membrane assembly, and does not perform multi-stage filtration on the sewage in different filter tanks, resulting in many impurities in the sewage that are not filtered out, and it is very troublesome to clean these impurities. At the same time, these impurities are easily adsorbed on the membrane assembly, which not only reduces the filtering effect of the membrane assembly, but also easily causes damage to the membrane assembly, ultimately resulting in poor sewage treatment effect.

Therefore, a sewage treatment device with multi-stage filtering function is invented to solve the above problems.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In the prior art, when sewage is separated and filtered by membrane components, the sewage in different filter tanks is not subjected to multi-stage filtration, resulting in many impurities in the sewage that are not filtered out, and it is very troublesome to clean these impurities. At the same time, these impurities are easily adsorbed on the membrane components, which not only reduces the filtering effect of the membrane components, but also easily causes damage to the membrane components, ultimately resulting in poor sewage treatment effect. This embodiment is specially invented to solve the above problems.

As shown in FIGS. 1 to 6 , a sewage treatment device with a multi-stage filtering function according to an embodiment of the present invention comprises a housing 1, wherein an anaerobic tank 4, an aerobic tank 5 and an MBR membrane tank 6 are sequentially arranged inside the housing 1 along the water inlet direction, wherein a filtering mechanism 8 is arranged in each of the anaerobic tank 4, the aerobic tank 5 and the MBR membrane tank 6, wherein the filtering mechanism 8 comprises a filtering block 801, wherein the filtering block 801 is fixedly connected to the pool wall in the water inlet direction, wherein a flow slot 802 extending in the water inlet direction is provided on the filtering block 801, wherein a filter screen 803 is provided at one end of the flow slot 802 away from the water inlet direction, wherein a push block 804 is slidably connected in the flow slot 802, and wherein two adjacent filtering blocks 801 are commonly connected to each other. An inclined pipe 805 is connected to the flow trough 802, and is used to guide sewage to flow in the opposite direction of the water inlet. A guide box 806 is provided at one end of the inclined pipe 805 away from the water inlet direction. The guide box 806 is connected to the corresponding flow trough 802, and the inclined pipe 805 is inclined toward the water inlet direction. An anoxic tank 3 is provided between the box body 1 and the anaerobic tank 4, a grille tank 2 is provided between the box body 1 and the anoxic tank 3, and an end of the box body 1 close to the grille tank 2 is provided with a water inlet 14 located on the upper side thereof. A plurality of aeration pipes 17 are provided at the bottom of the aerobic tank 5, and an equipment room 7 is provided between the box body 1 and the MBR membrane tank 6. A fan 18 is installed in the equipment room 7, and a plurality of aeration pipes 17 are connected to the fan 18.

A water storage tank 19 is provided on the upper side of the MBR membrane pool 6, and a membrane separation assembly 20 is provided in the MBR membrane pool 6. The water production pipe of the membrane separation assembly 20 is connected to the water storage tank 19. A water pump 21 is provided in the equipment room 7. The water inlet pipe on the water pump 21 is connected to the bottom of the water storage tank 19. The exhaust pipe on the water pump 21 extends out of the box body 1. A plurality of sewage outlets 15 distributed along the water inlet direction are provided at the bottom of the box body 1. A plurality of ventilation pipes 16 distributed along the water inlet direction are provided in the box body 1, and the plurality of ventilation pipes 16 are connected to the fan 18.

When in use, firstly, the sewage is injected into the grille pool 2 of the housing 1 through the water inlet 14, and a grille filter is provided in the grille pool 2, which can effectively filter the branches and debris in the sewage. It should be noted that the multiple pools in the housing 1 are connected by the through grooves on the pool wall, and the flow groove 802 on the filter block 801 is connected with the corresponding through grooves on the pool wall. After the sewage flows into the grille pool 2 and flows into the anoxic pool 3 through the through grooves on the pool wall, in the process of the sewage continuously flowing into the housing 1, the sewage in the anoxic pool 3 flows into the flow groove 802 on the filter block 801 through the through grooves on the pool wall, and a filter net 803 is provided in the flow groove 802, which can filter the large particles of impurities in the sewage. In the process of the sewage flowing in the housing 1, activated sludge is added to the anoxic pool 3, the anaerobic pool 4 and the aerobic pool 5, so that the microorganisms in the activated sludge can react with the organic matter in the sewage.

By intermittently starting the fan 18, the fan 18 exchanges the gas in the grid pool 2, the anoxic pool 3, the anaerobic pool 4 and the MBR membrane pool 6 through the ventilation pipe 16, and the aeration pipe 17 aerates the aerobic pool 5, so that the microorganisms can better react with the organic matter, thereby improving the biological filtration efficiency. When the sewage enters the membrane separation component 20 and is filtered, the sewage passing through the membrane separation component 20 is filtered and flows into the water storage tank 19 through the production pipe on the membrane separation component 20. A booster water pump is provided on the production pipe on the membrane separation component 20, which can better inject the generated clean water into the water storage tank 19, and the sewage outlet 15 is provided, which can discharge the sludge in different pools in the box body 1 to the outside. At the same time, under the action of the water pump 21, the clean water in the water storage tank 19 can be disinfected and discharged to the outside of the box body 1 through the water inlet pipe and the drain pipe on the water pump 21, and the impurities in the sewage can be filtered multiple times, reducing the amount of impurities flowing into the MBR membrane pool 6, thereby effectively improving the efficiency of sewage treatment.

When the filter 803 filters the sewage flowing into the box 1, when the impurities accumulated at the filter 803 gradually increase, the impurities at the filter 803 cannot be cleaned and collected in time. At this time, the filter 803 is easily blocked by the impurities, resulting in obstruction of the flow of sewage, which makes it inconvenient to better filter the sewage. Therefore, further improvements are made based on the above embodiment.

As shown in Figures 7 to 11, a blocking plate 807 located at the opening of the guide box 806 is slidably connected in the filter block 801 away from the water inlet direction. The blocking plate 807 can block the corresponding guide box 806. One end of the blocking plate 807 away from the guide box 806 is connected to the filter block 801 through a first elastic member 808. A push rod 809 is provided on each push block 804. The free end of the push rod 809 away from the water inlet direction is fixedly connected to the corresponding blocking plate 807. A transmission mechanism 9 is commonly provided between the multiple filter blocks 801, and the transmission mechanism 9 includes at least two Transmission block 901, two adjacent filter blocks 801 are fixedly connected by a transmission block 901, and a transmission plate 902 is slidably connected to the multiple filter blocks 801 and the transmission block 901. The transmission plate 902 is provided with multiple inclined grooves 903 corresponding to the push blocks 804. Each filter block 801 is slidably connected with a guide rod 904, one end of each guide rod 904 is fixedly connected to its corresponding push block 804, and the other end of each guide rod 904 is fixedly connected to an insertion rod 905, and each insertion rod 905 is inserted into the corresponding inclined groove 903.

A motor 906 is installed in one of the filter blocks 801, and a disc 907 is coaxially provided at the output end of the motor 906. A connecting rod 908 is eccentrically hinged at one end of the disc 907 close to the transmission plate 902, and a free end of the connecting rod 908 is hinged to one end of the transmission plate 902. A collecting box 10 connected to the flow slot 802 is provided on the side of the filter block 801 close to the water inlet direction, and a filter box 11 is detachably connected to the collecting box 10. A baffle 12 located at the opening of the collecting box 10 is slidably connected to the filter block 801, and an end of the baffle 12 away from the flow slot 802 is connected to the filter block 801 through a second elastic member 13. The free end of the push rod 809 close to the water inlet direction is fixedly connected to the baffle 12, and the sliding distance of the push block 804 is less than the distance between the bottom of the flow slot 802 and the guide box 806.

It should be noted that a liquid level sensor is provided on the upper side of the flow trough 802, and the liquid level sensor is electrically connected to the motor 906. When the large particles of impurities filtered on the filter 803 gradually increase, the filter holes on the filter 803 are gradually blocked, resulting in poor flow of sewage in the flow trough 802. The liquid level sensor detects that the water level in the flow trough 802 gradually increases, so that the motor 906 is started, and the motor 906 drives the disc 907 to rotate. When the eccentric point of the disc 907 and the connecting rod 908 is In the process of rotating from the far right to the far left, the disc 907 drives the transmission plate 902 to slide to the left along the filter block 801 and the transmission block 901 through the connecting rod 908. Since the inclined groove 903 is in an inclined state with the left lower and the right higher, the transmission plate 902 drives the guide rod 904 to slide upward along the filter block 801 through the inclined groove 903 and the insertion rod 905, so that the guide rod 904 drives the push block 804 to slide upward along the flow groove 802, so that the push block 804 can clean the residual impurities on the filter net 803.

At the same time, the push block 804 drives the blocking plate 807 to slide upward along the filter block 801 through the push rod 809, and the first elastic member 808 is compressed. At this time, the blocking plate 807 gradually stops blocking the opening of the guide box 806. At this time, when the sewage in the aerobic pool 5 flows into the filter block 801 in the MBR membrane pool 6, since the filter screen 803 is partially blocked by impurities, the sewage can partially impact the filter screen 803 through the flow channel 802, and in the process of the water level in the flow channel 802 rising, the sewage can flow in the opposite direction to the adjacent filter block through the guide box 806 and the inclined pipe 805. 801 is filtered again in the flow groove 802 on 801. When the push block 804 slides upward along the flow groove 802 to the limit position, the connecting port of the inclined tube 805 and the flow groove 802 is higher than the position of the push block 804, and the connecting port of the inclined tube 805 and the flow groove 802 is close to the position of the filter screen 803, so that the reverse-flowing sewage can wash the filter screen 803 and the impurities remaining on the filter screen 803. When the filter screen 803 located in the aerobic pool 5 is not blocked by impurities, the reverse-flowing sewage is filtered again through the filter screen 803 and flows into the aerobic pool 5.

When the filter screen 803 in the aerobic tank 5 is blocked by impurities, the sewage flowing from the anaerobic tank 4 to the filter block 801 in the aerobic tank 5 flows again to the flow channel 802 in the anaerobic tank 4 through the guide box 806 and the inclined pipe 805, so that the sewage flowing in the opposite direction also flows into the flow channel 802 in the anaerobic tank 4. At the same time, the push block 804 drives the baffle 12 through the push rod 809 to no longer block the opening of the collection box 10, and the second elastic member 13 is compressed. At this time, a part of the sewage drives the impurities to flow into the filter box 11 in the collection box 10, so that the filter box 11 filters the impurities inside it through the collection box 10, and the filtered sewage flows into the anaerobic tank 4 through the collection box 10 and the bottom of the filter box 11.

When the eccentric point of the disc 907 and the connecting rod 908 rotates from the leftmost side to the rightmost side, the disc 907 drives the transmission plate 902 to slide rightward along the filter block 801 and the transmission block 901 through the connecting rod 908. At this time, the transmission plate 902 drives the guide rod 904 to slide downward along the filter block 801 through the inclined groove 903 and the insertion rod 905, so that the guide rod 904 drives the push block 804 to slide downward along the flow groove 802, and the push block 804 no longer squeezes the push rod 809. At this time, under the action of the first elastic member 808 and the second elastic member 13, the blocking plate 807 and the baffle 12 block the openings of the guide box 806 and the collection box 10, and during the operation of the motor 906, the weight Repeating the above movement can not only perform multi-stage filtration on the sewage, but also filter the sewage for multiple times under the action of the inclined tube 805, and the sewage can rinse the filter screen 803, and it is also convenient to collect impurities in the reverse-flowing sewage into the filter box 11. When the liquid level sensor detects that the water level in the flow channel 802 drops to the initial position, the motor 906 stops running, and the push block 804 is located at the lowermost position of the flow channel 802, which is convenient for the sewage to flow better in the flow channel 802. Since the filter box 11 and the collection box 10 are disassembled and connected in an interference fit manner, it is convenient to take the filter box 11 out of the collection box 10, and it is convenient to clean the impurities in the filter box 11.

By means of a plurality of filter blocks 801 and filter screens 803 distributed at different positions in the housing 1, the sewage can be filtered in multiple stages from the water inlet direction, thereby improving the efficiency of sewage filtration. When impurities in the sewage block the filter holes of the filter screen 803, the push block 804 slides along the flow channel 802, so that the push block 804 cleans the impurities on the filter screen 803. Under the joint action of the inclined tube 805 and the guide box 806, the sewage can not only flow in the reverse direction, but also flush the filter screen 803, and at the same time, the impurities can flow back to the filter block 801 closest to the water inlet direction, thereby facilitating the collection of the filtered impurities, thereby further improving the efficiency of sewage treatment.

The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
