Pressure-bearing filter tank type ultramicro-power sewage treatment device

Abstract

The invention discloses a pressure-containing filter tank type ultra-micro power sewage treatment device, which comprises an anaerobic tank, a pipeline and an anoxic tank. Both the anaerobic tank and the anoxic tank have a rectangular box-like structure. There is a water inlet in the middle of the upper surface of the tank, and a water outlet at the lower right end of the anoxic tank. A pipe is fixed in the middle of the lower surface of the anaerobic tank, and a pipe is also fixed on the upper surface of the anoxic tank. The cleaning plate can clean the anaerobic tank and the The sludge in the anoxic tank is not easy to accumulate sludge in the anaerobic tank and the anoxic tank, which will not cause blockage of the device, and the efficiency of sewage treatment is high. The cleaning plate in the anaerobic tank and anoxic tank also has the function of stirring sewage. , so that the sewage can be fully mixed and flowed, which improves the efficiency of sewage treatment and saves time. It is suitable for a large number of sewage treatment, and does not need to set up multiple anaerobic tanks and anoxic tanks.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a pressurized filter type ultra-micro dynamic sewage treatment device. Background technique [0002] The "micro-power" sewage treatment device currently operating in my country's environmental protection industry is combined with the special conditions of the Qinghai area's topography and severe cold seasons. There are still many deficiencies, specifically high altitude, low air pressure, long cold winter, and thick permafrost. Especially in rural areas there is no three-phase power supply. High investment in environmental protection and high operating costs have brought many difficulties to the normal operation of the sewage station. The pressurized filter type ultra-micro power sewage treatment device can save more than 50%-60% of power, with a daily water volume of 50 tons / day Take the sewage station as an example, only 2.75 kilowatts is enough, an...

Problems solved by technology

High investment in environmental protection and high operating costs have brought many difficulties to the normal operation of the sewage station. The pressurized filter type ultra-micro power sewage treatment device can save more than 50%-60% of power, with a daily water volume of 50 tons / day Take the sewage station as an example, only 2.75 kilowatts is enough, and the discharged clean water can reach the national first-class A label, but it still has the following disadvantages in actual operation:

[0003] 1. Sewage contains a lot of silt, and neither the anaerobic pool nor the anoxic pool is equipped with a device to clean up the silt. The anaerobic pool and the anoxic pool are prone to silt, which will cause blockage of the device for a long time and make the sewage treatment the efficiency drops;

[0004] 2. The anaerobic pool and the anoxic pool are connected through pipelines. When there is sludge in the anaerobic pool and the anoxic pool, it is inconvenient to disassemble and clean up, which will cause difficulties in the maintenance of the device, and it will take time and effort to clean up the sludge;

[0005] 3. The pipeline between the anaerobic pool and the anoxic pool is prone to water seepage after long-term use, and the sealing is poor, which will cause pollution to the outside world, and the effect of sewage treatment will decrease accordingly, which does not meet environmental protection requirements;

[0006] 4. Since the sewage is a cement mixture, which is relatively viscous and difficult to flow, the sewage treatment process inside the anaerobic pool and the anoxic pool is often slow, and the efficiency of sewage treatment is low, which takes a lot of time and requires a lot of sewage treatment. Setting multiple anaerobic pools and anoxic pools is a waste of space and high cost
