Problems solved by technology

However, in the above purification process, the purification cycle of sewage in the sedimentation device, coagulation device, flocculation device and filtration device is longer, especially in the flocculation process, the settling and floating speed of flocs is slow, so the purification of sewage is prolonged. Treatment time, reducing the efficiency of sewage purification treatment
In addition, in related technologies, a large number of settling devices are usually required, which not only occupies a large space, but also increases the cost of the sewage purification system

Abstract

The invention relates to the field of sewage treatment and in particular relates to a sewage purification system. The sewage purification system comprises a first dosing device, a second dosing device, a third dosing device, a coagulation tank, a flocculation tank, a filter device and a liquid storage tank, wherein the first and second dosing devices are communicated with the coagulation tank via pipelines; the third dosing device is communicated with the flocculation tank via a pipeline; the coagulation tank is communicated with the flocculation tank via a pipeline; the filter device comprises a motor, a rotating shaft, adsorption discs, positioning discs, scrapers, sewage tanks, sub-sewage tanks and clear water tanks sleeved outside the sewage tanks; the rotating shaft is arranged on the sewage tanks; a plurality of adsorption discs are arranged on the rotating shaft; each adsorption disc is matched with a scraper; the sub-sewage tanks are fixedly arranged in the sewage tanks; the clear water tanks are communicated with the liquid storage tank via pipelines; the flocculation tank is communicated with the sewage tanks. The system has the beneficial effects that the system can effectively purify sewage and is short in cycle; the purified sewage reaches the discharge standard, can be reused according to the production requirements, and has a wide range of application.

Description

Technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage purification system. Background technique [0002] With the continuous progress of society, mankind produces a large amount of sewage in production and life. Sewage includes domestic sewage, industrial sewage and agricultural sewage. Since sewage contains a large number of pollutants, such as pathogen pollutants, aerobic pollutants, chemical toxic pollutants, petroleum pollutants, radioactive pollutants, etc., the direct discharge of unpurified sewage will affect the environment and ecology. And human health poses a huge threat and causes serious economic losses. [0003] In related technologies, sewage needs to be purified to make the purified sewage meet the discharge standard. Generally speaking, sewage purification systems include sedimentation devices, aerobic biochemical devices, coagulation devices, flocculation devices, filtering devices, etc. By adding different chem...
