Abstract

The invention discloses a multi-stage sewage treatment device. The multi-stage sewage treatment device comprises a sewage treatment device body, wherein an oxidation reaction tank, a filter net, a fiber sphere filler layer, a filter membrane, a biological membrane reaction tank and a disinfection tank are sequentially arranged on the sewage treatment device body from top to bottom; a motor is arranged at the top part of the sewage treatment device body; the lower end of the motor is connected with a stirring rod; the stirring rod extends into the oxidation reaction tank; the upper part of thesewage treatment device body is provided with a water inlet, and the lower part of the sewage treatment device body is communicated with a water drain pipe; a valve is arranged on the water drain pipe. The multi-stage sewage treatment device has the advantages that a plurality of equipment of different functions can be integrated into one device; the functions of multi-stage dirt removal and waterbody precipitation and purification can be realized in the limited space; the land occupation area is small, and the manufacturing cost is low; by utilizing the gravity reduction of water, the pump is not required, and the energy source is saved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a multi-stage sewage treatment device. Background technique [0002] With the continuous development of the economy and the growth of the population, while creating benefits, it also creates various pollutions. The shortage of water resources has become a limiting factor restricting the further development of our country. In order to achieve sustainable development, it is necessary to reuse sewage treatment. The key to achieving this goal is that most of the current sewage treatment devices are composed of multiple devices. However, due to the large area of ​​the device and the high manufacturing and maintenance costs, it cannot be widely used. Contents of the invention [0003] The purpose of the present invention is to solve the problem that most of the current sewage treatment devices are composed of multiple devices, but due to the large area of ​​the device, the h...
