Abstract

The invention discloses a sewage treatment method. A pre-treatment pond, a biological treatment pond and a chemical treatment pond are included. The treatment method comprises the following steps of S1, precipitating municipal sewage in the pre-treatment pond, and removing suspended solids; S2, guiding the municipal sewage into the biological treatment pond through a water pump by the pre-treatment pond, and utilizing microorganisms for degrading organic matters and biodegradable pollutants in the municipal sewage in the biological treatment pond, thus meeting an emission standard; S3, guiding the municipal sewage into the chemical treatment pond through the water pump by the pre-treatment pond, utilizing chemical substances for oxidative-precipitating pollutants in the municipal sewage in the chemical treatment pond, and treating the pollutants difficult to be degraded in the municipal sewage. The sewage treatment method provided by the invention has the beneficial effects that a sewage treatment process is simplified, sewage treatment steps and the method are simplified, impurities and nitrogen and phosphorus contents in the municipal sewage are simply and effectively reduced, and the emission standard can be quickly met.

Description

technical field [0001] The invention relates to the technical field of municipal sewage treatment, in particular to a sewage treatment method. Background technique [0002] With the development of the economy and the continuous improvement of people's living standards, the quality of sewage water is also undergoing constant changes. Wastewater produced continuously in life, and some sewage discharged illegally, will eventually flow to municipal sewage treatment projects, and impurities and nitrogen in municipal sewage Phosphorus content is relatively large, and the sewage treatment needs to meet the discharge standard before it is allowed to be discharged. The current sewage treatment method is cumbersome and complicated, and the efficiency is relatively low. Contents of the invention [0003] The purpose of the present invention is to provide a sewage treatment method to solve the problems raised in the above background technology. [0004] In order to achieve the above ...
