Abstract

The invention discloses an integrated sewage treatment device. The integrated sewage treatment device comprises a membrane bioreactor (MBR), a UV pond and a lifting device, wherein the lifting device is arranged at one side of the MBR, and the UV pond is arranged at the other side of the MBR; a membrane assembly is arranged on the inner wall of the MBR and provided with a filler frame; an aerator pipe is arranged at the bottom of the MBR, one end of the aerator pipe is connected with the lifting device, micropore aeration openings are formed in the aerator pipe, a lifting pump is arranged in the lifting device, and a lifting pipe is arranged outside the lifting device and communicated with the MBR; a UV lamp bracket is arranged on the inner wall of the UV pond and provided with UV lamp tubes, and a membrane water outlet pipe is arranged on the inner wall of the side, close to the MBR, of the UV pond and is communicated with the membrane assembly. Using a biological membrane and an ultrafiltration membrane for main sewage treatment, the device is high in treatment efficiency, small in occupied area, efficient and reliable, and sewage retention time is short.

Description

technical field [0001] The invention belongs to sewage treatment equipment, in particular to an integrated sewage treatment device. Background technique [0002] China is a water-scarce country, and sewage treatment and reuse are effective measures to develop and utilize water resources. Sewage reuse is to use urban sewage and industrial sewage for non-drinking purposes such as greening, flushing, and replenishment of ornamental water bodies after being treated by membrane bioreactors and other equipment, while using clean water for drinking and other high-quality water-required purposes. Urban sewage and industrial sewage are available nearby, which can avoid long-distance water transportation and realize the full utilization of water resources through nearby treatment. pollute groundwater sources. Sewage reuse has been widely used in many water-scarce areas in the world, and it is considered the most practical technology for sewage treatment in the 21st century. [0003...
