Integrated sewage treatment device and process

Abstract

The invention discloses an integrated sewage treatment device, which comprises a shell, wherein the shell is internally provided with a regulating tank, an aerobic tank, a hypoxic tank and a sedimentation tank in sequence, the top of the shell is provided with a first conveying pump, a circulation pump, a solar heating device, a second conveying pump and a water filter in sequence, the regulatingtank is connected to the aerobic tank by the first conveying pump, a circulating water outlet of the aerobic tank is connected to the solar heating device by the circulation pump, and a drainage outlet of the solar heating device is connected to a circulating water inlet of the aerobic tank by a pipeline, the bottom of the aerobic tank is provided with a first aeration pipe, a drainage outlet of the aerobic tank is connected to the hypoxic tank through a pipeline, a second aeration pipe is arranged at the bottom of the hypoxic tank, the hypoxic tank is connected to the sedimentation tank by apipeline, and a water outlet of the sedimentation tank is connected to the filter by the second conveying pump. The integrated sewage treatment device has the beneficial effects that the aerobic reaction effect is improved, the water treatment time is reduced, the water treatment effect is improved, the utilization effect of solar energy is improved, and the cost of the device is reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an integrated sewage treatment device and a treatment process. Background technique [0002] With the continuous development of human society and the continuous expansion of the city, the water consumption and drainage of the city are increasing, which aggravates the tension of water use and the pollution of water quality, and the environmental problems are becoming more and more prominent. The resulting water crisis has become a socio-economic important constraints to development. [0003] In recent years, although the efficiency of sewage treatment in my country has been continuously improved, the problem of eutrophication caused by nitrogen and phosphorus pollution has not only not been solved, but has become increasingly serious. With the intensification of water eutrophication, the main contradiction of sewage treatment has changed from the removal of organic pollu...
