[0002] At present, the domestic sewage treatment mode of small towns in Chongqing basically adopts the centralized treatment mode. Due to factors such as poor municipal pipe network construction and weak operation and management capabilities in small towns, the treatment effect is often unsatisfactory, causing serious damage to surrounding water bodies. Threats, even threats to the safety of water bodies in the Three Gorges Reservoir area

Embodiment 1
[0014] A kind of urban domestic sewage treatment system of the present invention, it comprises collection well 1, anaerobic pond 2, aerobic pond 3, diatom concentrate reaction unit 4, wherein collection well 1, anaerobic pond 2, aerobic pond 3 1. The diatomite reaction unit 4 is connected successively, and the diatomite reaction unit 4 is provided with two outlets, one is a water outlet, and the other is a mud outlet. The aerobic pool 3 is connected with an air explosion pump. The anaerobic tank 2 is provided with a push-flow pump. The sludge outlet of the diatomite reaction unit 4 is connected to the aerobic pool 3 . A return pump is provided between the sludge outlet of the diatomite reaction unit 4 and the aerobic tank 3 . The bottom of the diatomite reaction unit 4 is conical, and the angle of the conical bottom is 35 degrees.

Abstract
The invention relates to a municipal domestic sewage treatment system which comprises a water gathering well, an anaerobic pool, an aerobic pool and a purified diatomite reaction unit, wherein the water gathering well, the anaerobic pool, the aerobic pool and the purified diatomite reaction unit are sequentially connected. The purified diatomite reaction unit is provided with two outlets, one is awater outlet, and the other one is a sludge discharge outlet. According to the municipal domestic sewage treatment system, the sludge inoculation cycle is obviously shorter than that of a traditionalactivated sludge process, nutrient substances are not required to be added, microorganisms can grow well, sludge backflow and mixed liquid backflow have little effect on the water quality of effluentof the system, and clear water backflow has obvious treatment effect on the system.
Description
technical field [0001] The invention relates to an urban domestic sewage treatment system. Background technique [0002] At present, the domestic sewage treatment mode of small towns in Chongqing basically adopts the centralized treatment mode. Due to factors such as poor municipal pipe network construction and weak operation and management capabilities in small towns, the treatment effect is often unsatisfactory, causing serious damage to surrounding water bodies. threats, and even threaten the water safety of the Three Gorges Reservoir area. In the prior art, in order to meet the requirements of domestic sewage treatment in small towns, from the perspective of decentralized treatment and reuse, and according to the characteristics of urban domestic sewage, a "composite A / O diatom concentrate" process small town domestic sewage DESAR treatment system was designed , its main features are: combined with the characteristics of diatom concentrate water treatment process, the A...
