Description

Technical Field

[0001] The invention relates to the technical field of sewage and wastewater treatment, and in particular to an improved biochemical sewage treatment system. Background Art

[0002] CASS is the abbreviation of cyclic activated sludge method, also known as circulating activated sludge process, which is a new type of sewage treatment process.

[0003] In the pre-reaction zone of the CASS sewage treatment process, microorganisms can quickly absorb most of the soluble organic matter in the sewage through the rapid transfer mechanism of enzymes, and undergo a high-load rapid accumulation process of the substrate, which has a good buffering effect on the influent water quality, water volume, pH and toxic and harmful substances, and inhibits the growth of filamentous bacteria, which can effectively prevent sludge swelling; then it undergoes a low-load substrate degradation process in the main reaction zone. The CASS sewage treatment process integrates reaction, sedimentation, drainage and functions. The degradation of pollutants is a plug flow process in time, while the microorganisms are in aerobic, anoxic and anaerobic periodic changes, thereby achieving the removal of pollutants. At the same time, it also has good denitrification and phosphorus removal functions, so it is widely used.

[0004] Sewage enters the main reaction zone through the pre-reaction zone, and the main reaction zone is the main place for the final removal of organic substrates. In the operation process of the existing technology, the aeration intensity of the main reaction zone and the dissolved oxygen intensity in the aeration tank are usually controlled to make the main solution in the reaction zone in an aerobic state, ensuring that there is an aerobic environment outside the sludge flocs for nitrification, and the inside of the activated sludge structure is basically in an anoxic state, and the transfer of dissolved oxygen into the sludge flocs is limited, while the higher nitrate concentration (gradient) can better penetrate into the flocs and effectively carry out denitrification, so that the degradation of organic pollutants and synchronous nitrification and denitrification occur simultaneously in the main reaction zone.

[0005] However, in the prior art, when the CASS pool is inspected and repaired, the sludge in the CASS pool needs to be pumped into another CASS pool manually through a submersible pump. However, the submersible pump is generally fixed at the same position, and the sludge that can be pumped out can only be pumped out within a certain range. The sludge in other positions cannot be pumped out, and the position of the submersible pump needs to be adjusted manually, which is very inconvenient and has low work efficiency. Summary of the invention

[0006] The purpose of the present invention is to provide an improved biochemical sewage treatment system to solve the above-mentioned problems.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] The present invention discloses an improved biochemical sewage treatment system, comprising two CASS pools arranged side by side and movable frames respectively arranged on the top of the two CASS pools, wherein the two ends of the movable frames are controlled to move by longitudinal movement components, a transverse movement vehicle is arranged on the top surface of the movable frame, and the transverse movement vehicle is controlled to move by the transverse movement component installed on the movable frame, a sludge pump is installed on the transverse movement vehicle, an inlet pipe is connected to the inlet end of the sludge pump, and the other end of the inlet pipe penetrates through the strip hole provided on the movable frame and then penetrates into the CASS pool, an outlet end of the sludge pump is connected to a transverse pipe, and the other end of the transverse pipe is connected to a telescopic pipe, and the other end of the telescopic pipe is connected to an outlet pipe, and the other end of the outlet pipe penetrates into the adjacent CASS pool.

[0009] Furthermore, the longitudinal movement assembly includes two symmetrically arranged longitudinal movement plates arranged on the top edge of the CASS pool and a moving wheel mechanism installed on the longitudinal movement plates. The moving wheel mechanism is driven by a driving motor, and the moving wheels in the moving wheel mechanism roll in a track arranged on the top edge of the CASS pool. Both ends of the moving frame are respectively installed on the longitudinal movement plates.

[0010] Furthermore, the outlet pipe is connected to the longitudinal movement plate on the adjacent CASS pool through a first support frame.

[0011] Furthermore, baffles are provided at both ends of the track.

[0012] Furthermore, the transverse movement assembly includes a transverse frame connected to the front end of the mobile frame, the transverse frame is rotatably connected to a screw rod, the screw rod is driven by a transverse movement motor, a driving plate is threadedly connected to the rod body of the screw rod, the driving plate is slidably connected to the transverse frame, and the driving plate is connected to the transverse movement vehicle.

[0013] Furthermore, the transverse tube is installed on the movable frame through a second supporting frame.

[0014] Furthermore, a partition plate is provided inside the CASS tank to separate the CASS tank into a pre-reaction zone and an aerobic zone.

[0015] Furthermore, a connecting hole is provided on the partition plate.

[0016] Compared with the prior art, the beneficial technical effects of the present invention are:

[0017] When the CASS pool is inspected and repaired, the present invention transfers the sludge through a sludge pump that can be moved at any time, and the range of sludge extracted is expanded, which reduces manual participation, greatly improves work efficiency, facilitates the complementation of nitrifying bacteria, improves the efficiency of sewage treatment, reduces environmental risks, and two-way entry into the anaerobic tank improves the reproduction capacity of denitrifying bacteria, providing a strong guarantee for sewage treatment.

[0025] The two ends of the movable frame 2 are controlled to move by a longitudinal movement assembly. A transverse movement vehicle 3 is provided on the top surface of the movable frame 2. The longitudinal movement assembly includes two symmetrically arranged longitudinal movement plates 10 arranged on the top edge of the CASS pool 1 and a moving wheel mechanism 11 installed on the longitudinal movement plates 10. The moving wheel mechanism 11 is a prior art, including a moving wheel installed at the bottom of the longitudinal movement plate 10.

The moving wheel mechanism 11 is driven by a driving motor 12, and the moving wheel in the moving wheel mechanism 11 rolls in a track 13 arranged on the top edge of the CASS pool 1. The two ends of the movable frame 2 are respectively installed on the longitudinal movement plates 10.

[0026] Baffles 15 are provided at both ends of the track 13 to prevent the moving wheel mechanism 11 from rushing out of the track 13 .

[0027] The transverse shifting vehicle 3 is controlled to move by a transverse shifting assembly installed on the mobile frame 2.
