Dispersed domestic sewage ecological purifying system

Abstract

The invention discloses a dispersed domestic sewage ecological purifying system. The dispersed domestic sewage ecological purifying system comprises local sewage treatment systems, sewage sources, a sewer network and a sewage treatment plant. The sewage sources are connected with the local sewage treatment systems. The sewage treatment systems are connected with the sewage treatment plant throughthe sewer network. There are a plurality of the local sewage treatment systems and the sewage sources. The sewer network is a pressure sewer. The local sewage treatment systems are used for treating sewage received from the sewage sources. The sewer network is used for conveying the sewage which cannot be treated by the local sewage treatment systems. The sewage treatment plant is used for treating the sewage which is conveyed from the sewer network and cannot be treated by the local sewage treatment systems. One of the local sewage treatment systems comprises a detecting device, a receiving device, a first treatment device, a second treatment device, a first suction pump, a storage device, a second suction pump, a third suction pump, an air conveying device, and a control device.

Description

technical field [0001] The invention relates to a device in the field of sewage treatment, in particular to a decentralized domestic sewage ecological purification system with various functions. Background technique [0002] With the continuous development of society and economy, the problem of water pollution is becoming more and more serious, and sewage treatment has become a key issue that human beings urgently need to solve. According to surveys, the economic loss caused by water pollution in China accounts for about 1.46% to 2.84% of GDP, and the consequences caused by eutrophication of water bodies are particularly serious. In recent years, although the country and localities have invested huge sums of money every year, the degree of eutrophication of water bodies has not decreased so far. At present, it is well known that the ecological purification system of sewage consists of conveying sewage from multiple local sources (such as individual dwellings) to the sewer n...

Problems solved by technology

[0003] However, both currently known arrangements have significant disadvantages

Providing a sewer network and sewage treatment plant capable of treating all the sewage generated in a given area requires a significant investment of resources, both in terms of the infrastructure required to transport the sewage to the treatment units, and all the associated Both are extremely costly to run and it is undesirable to provide a separate sewage treatment unit for each dwelling to individually treat all the sewage from each dwelling
