Problems solved by technology

[0004] However, the above-mentioned treatment process only does simple filtering, and there are still serious problems in the subsequent discharge
For example, sewage discharged through underground pipelines still contains small solid pollutants (less than 0.25cm), which tend to accumulate and block pipelines after long-term discharge
At the same time, the treatment in the prior art does not treat the components of the discharged sewage, and the sewage still contains many toxic substances, and the direct discharge does not meet the national discharge standards

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a sewage treatment system. Background technique [0002] With the acceleration of industrialization and urbanization in our country, environmental protection issues have become more and more prominent. For example, the impact of garbage dumps on the surrounding environment, the impact of factory sewage discharge on surrounding rivers, and the random discharge of domestic waste. These issues have been paid more and more attention as the news has been exposed. In real life, the common pollutions include sewage and sewage discharge from small factories, as well as large amounts of domestic garbage and excrement in cities and towns, all of which bring serious pollution to people's living environment. Among them, the common feature of these pollutants is that solid pollutants are mixed with liquid sewage, which is difficult to handle. [0003] The existing technology has done...
