Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a sewage treatment device and filtering equipment thereof. Background Art

[0002] Flocculants are widely used in the field of sewage treatment. After flocculants are added to sewage, the suspended matter in the sewage will combine with the flocculants to produce flocs that are easy to filter.

[0003] The existing filtering equipment is provided with an equipment body and a filtering mechanism. The sewage after reacting with the flocculant is injected into the filtering equipment, and the floccules are removed after being filtered by the filtering mechanism. Due to the long-term use of the filtering equipment, a large amount of floccules will accumulate on the surface of the filtering mechanism, causing the filter holes on the surface of the filtering mechanism to be blocked, and the water cannot seep out, resulting in the filtering equipment being unable to filter normally. Therefore, it is necessary to manually replace the blocked filtering mechanism, and the replacement of the filtering mechanism requires the filtration equipment to be shut down to ensure that the sewage injection is stopped during the replacement process, which leads to low filtration efficiency of the existing filtering equipment.

[0033] The extraction mechanism 20 is arranged on a pipe connected to the transition chamber 102, and is used to extract the cleaned sewage in the transition chamber 102 from the pretreatment mechanism 10. Since the sewage chamber 101 is connected to the transition chamber 102 through the through hole 1201, when the extraction mechanism 20 extracts the cleaned sewage in the transition chamber 102, the sewage entering the sewage chamber 101 can actively flow from the sewage chamber 101 to the transition chamber 102.

[0034] In one example, the extraction mechanism 20 is implemented to include a lift pump.

[0035] Furthermore, the sewage treatment device also includes a phosphorus removal mechanism 30.

[0037] Preferably, the dephosphorization mechanism 30 further includes a first supply member 32. The first supply member 32 includes a phosphorus storage tank 321, and the phosphorus storage tank 321 is used to store a dephosphorization agent. The phosphorus storage tank 321 is connected to the first mixing chamber 3101 formed by the first mixing member 31 through a pipeline. The dephosphorization agent stored in the phosphorus storage tank 321 is injected into the first mixing chamber 3101 through a pipeline, so that the dephosphorization agent is mixed with the decontaminated sewage in the first mixing chamber 3101 to reduce the phosphorus content in the sewage.

[0038] Preferably, the first supply member 32 further includes a supply pump 322. The supply pump 322 is installed on a pipeline connecting the phosphorus storage tank 321 and the first mixing member 31, and is configured to transport the dephosphorizing agent stored in the phosphorus storage tank 321 to the first mixing chamber 3101.

The second mixing chamber 4101 formed by the second mixing member 41 is connected to the first mixing chamber 3101 formed by the first mixing member 31 through a pipeline, so that the sewage treated by the phosphorus removal mechanism 30 is injected into the second mixing chamber 4101 through a pipeline, and the flocculant injected into the second mixing chamber 4101 coagulates with the suspended matter in the sewage to form a larger flocculant, which is convenient for subsequent filtration to remove the flocculant.

[0042] Preferably, the suspended matter removal mechanism 40 further includes a second supply member 42. The second supply member 42 includes a storage tank 421, and the storage tank 421 is used to store flocculants. The storage tank 421 is connected to the second mixing chamber 4101 formed by the second mixing member 41 through a pipeline.

The delivery pipe 52 is installed between the second mixing member 41 and the filtering mechanism 53, so that the sewage mixed with the flocculant is injected into the filtering cavity 5301 formed by the filtering mechanism 53 through the delivery pipe 52. The filtering mechanism 53 allows the water in the filtering cavity 5301 to seep out, so that the flocculants generated by the mixing of the suspended matter in the sewage and the flocculant are retained in the filtering cavity 5301 by the filtering action of the filtering mechanism 53, and the water seeps into the gap between the inner wall of the installation cavity 5101 and the filtering mechanism 53.

[0047] Preferably, the device body 51 is formed with a discharge port 5102 connected to the installation cavity 5101, and the discharge port 5102 is used to discharge the filtered water.

[0048] It is worth mentioning that the filtering device 50 further includes at least one control valve 54. The control valve 54 is installed on the delivery pipe 52, and is used to control the flow path of the delivery pipe 52 and the flow rate.

[0049] Preferably, the device body 51 includes a tank body 511 and an opening and closing member 512. The tank body 511 forms the installation cavity 5101, the discharge port 5102 and an operation port 51101 communicated with the installation cavity 5101. The opening and closing member 512 is installed on the tank body 511 in an opening and closing manner to seal and open the operation port 51101. The filter mechanism 53 is detachably installed on the installation cavity 5101, so that when the filter mechanism 53 is blocked by floccules and water cannot seep out of the filter cavity 5301, the staff can replace the filter mechanism 53 blocked by floccules through the operation port 51101, so that the filter device 50 can operate normally.

[0050] Preferably, the filtering mechanism 53 comprises a filter bag 531 and an assembly part 532. The filter bag 531 forms the filter cavity 5301 and an injection port 53101 communicating with the filter cavity 5301. The assembly part 532 is annular and made of a hard material, and is mounted on one end of the filter bag 531 forming the injection port 53101, so that the assembly part 532 keeps the injection port 53101 in an open state.

[0051] In one embodiment, the inner wall of the assembly part 532 forms an internal thread, and the tank body 511 forms a partial top wall of the installation cavity 5101 and extends downward to form at least one connecting portion 5111. The outer periphery of the connecting portion 5111 forms an external thread, and the assembly part 532 is threadedly installed on the connecting portion 5111, so that the staff can disassemble and assemble the filtering mechanism 53.

[0052] It is understandable that the assembly and disassembly method between the assembly part 532 and the connecting part 5111 described in the present application is not limited to threaded connection, and methods such as snap-on connection and connection with fasteners are also applicable to the assembly part 532 and the connecting part 5111.

[0053] Preferably, the filtering device 50 is provided with a plurality of filtering mechanisms 53 and a plurality of control valves 54. The filtering chamber 5301 formed by each filtering mechanism 53 is communicated with the second mixing chamber 4101 formed by the second mixing member 41 through the delivery pipe 52, and each delivery pipe 52 is provided with a control valve 54.

[0054] In a preferred embodiment, when the filtering device 50 is in operation, at least one of the control valves 54 is in a closed state, and the other control valves 54 are in an open state. In this way, the sewage mixed with the flocculant is injected into the filtering mechanism 53 connected thereto through the delivery pipe 52 whose flow path is connected thereto for filtering. When the filtering mechanism 53 is blocked by flocculants, the control valve 54 provided on the delivery pipe 52 connected to the filtering mechanism 53 is closed to facilitate replacement by the staff. The control valve 54 originally in a closed state is opened, so that the other filtering mechanisms 53 can operate normally, so that the filtering device 50 can operate uninterruptedly and the filtering efficiency can be improved.

[0055] Furthermore, the sewage treatment device also includes an aeration tank 60 .

[0056] The aeration tank 60 is connected to the discharge port 5102 through a pipeline, so that the sewage filtered by the filtering device 50 flows into the aeration tank 60 to enter the aeration stage.
