Biochemical water purifier

Abstract

The invention discloses a biochemical water purifier. The biochemical water purifier comprises a machine body, a water inlet pipe at the left end of the machine body and a water outlet pipe at the right end of the machine body. A hydrolysis acidification tank and a multi-stage aerobic tank are orderly arranged in the machine body from left to right. The right side of the multi-stage aerobic tank is provided with a filtering tank. A fiber turntable filter is arranged in the filtering tank. The right side of the fiber turntable filter is provided with a clear water tank. The clear water tank iscommunicated with a rotation drum of the fiber turntable filter. The biochemical water purifier realizes the integration of sewage treatment, solves the technical problem of the existing combined device composed of single devices, greatly reduces the space occupied by the device, reduces the use and maintenance costs and increases the efficiency of wastewater treatment.

Description

technical field [0001] The invention belongs to the field of sewage treatment equipment, in particular to a biochemical water purifier. Background technique [0002] In the traditional biochemical sewage treatment process, the removal of SS and the removal of total phosphorus are all achieved by the sedimentation of the secondary sedimentation tank, but the SS content of the effluent is difficult to meet the requirements, especially to increase the SS content (≥10mg / L) After the request, it must go through a multi-level process. That is to say, advanced filtration treatment must be carried out. Flocculation and filtration facilities include V-shaped filter tank, active sand filter, fiber turntable filter, etc., and the above-mentioned filter facilities such as fiber turntable filter are independent of each other, and need to build steel structures or For the civil construction of the pool, the input cost and floor area are greatly increased.

Problems solved by technology

[0002] In the traditional biochemical sewage treatment process, the removal of SS and the removal of total phosphorus are all achieved by the sedimentation of the secondary sedimentation tank, but the SS content of the effluent is difficult to meet the requirements, especially to increase the SS content (≥10mg / L) After the request, it must go through a multi-level process

That is to say, advanced filtration treatment must be carried out. Flocculation and filtration facilities include V-shaped filter tank, active sand filter, fiber turntable filter, etc., and the above-mentioned filter facilities such as fiber turntable filter are independent of each other, and need to build steel structures or Civil construction pool body, input cost and floor area are greatly increased

[0003] Secondly, the ordinary A2O process has serious sludge run-off, and many small sewage treatment stations, due to neglect of management, the sludge concentration in the pool is getting lower and lower, and the effect is getting worse

[0004] Furthermore, when dealing with domestic wastewater and biochemical wastewater with a small amount of water, the MBR process is usually selected. There is no problem with the water output of the process equipment, but the operation of the MBR process is difficult, the operation cost is high, and the maintenance cost is high. The above are all recognized by the industry, especially It cannot be applied to rural wastewater treatment where the economy and management are relatively weak

[0005] In order to efficiently, conveniently and cost-effectively solve the problems of high SS and total phosphorus content in A2O effluent, the applicant proposed a new technical solution, which provided a biochemical water purifier
