Sewage treatment device

Abstract

The invention discloses a sewage treatment device. The device comprises a filtering precipitation chamber, the inside of the filtering precipitation chamber is separated into a filtration chamber and a precipitation chamber through a first filter screen, a central position at the top of the filtering precipitation chamber is provided with a sewage inlet pipe, a first telescopic motor is fixedly arranged on a side wall of the filtration chamber, the output end of the first telescopic motor is connected to a first telescopic rod, and one end of the first telescopic rod far from the first telescopic motor is inserted into the filtration chamber. According to the sewage treatment device provided by the invention, sewage can enter from the sewage inlet pipe, passes through the filtration chamber, the precipitation chamber, an anaerobic chamber, an aerobic chamber, a PH regulating chamber and a sterilization chamber in order, and clean purified water with moderate pH value can be obtained by a purified water outlet pipe, then the follow-up purified water is utilized, thus achieving the purpose of sewage treatment. At the same time, the sewage treatment device is convenient for cleaning and replacement of parts in the equipment, has no need for shutdown, greatly improves the sewage treatment efficiency, and saves the cost.

Description

technical field [0001] The invention relates to the technical field of environmental engineering, in particular to a sewage treatment device. Background technique [0002] With the process of industrialization and urbanization in our country, the increasingly serious water pollution not only reduces the use function of water, but further exacerbates the contradiction of water shortage, which has a serious impact on the sustainable development strategy that China is implementing, and also seriously It threatens the drinking water safety of urban residents and people's health. The common sewage treatment equipment in the prior art is to pass the sewage through the anaerobic chamber, the aerobic chamber and the sterilization chamber in sequence, and remove the impurities and various bacteria in the sewage, so as to obtain pollution-free clean water, and then reach the sewage level. Purpose of processing. However, there are still many problems in the existing sewage treatment ...

AI Technical Summary

Problems solved by technology

However, there are still many problems in the existing sewage treatment devices. For example, in the sewage treatment process, if the pH value of the sewage is not adjusted, it is easy to make the pH value of the purified water not meet the requirements, which is not conducive to the use of purified water. After a long period of use inside the equipment, it is easy to accumulate various pollutants, so that the parts of the sewage treatment equipment need to be shut down for cleaning or replacement, which seriously affects the efficiency of sewage treatment
