As a result, the Chengdu government is ensuring the quality of the city's wastewater discharges by investing in and constructing sewerage treatment facilities.
Chengdu's sewerage treatment involves many aspects, including sewage collection, sewage treatment and sewage discharge. In the Chengdu metropolitan area, the municipal government has invested a large amount of money in the construction of a sewer network that collects sewage from the city and treats it at a wastewater treatment plant. The sewage treatment plant uses biological treatment technology, physical treatment technology and chemical treatment technology to treat sewage.
Biological treatment technology is mainly through microorganisms to decompose and remove organic matter, chemical substances are removed using chemical reactions, while the removal of nitrogen, phosphorus and other inorganic substances need to be treated using a combination of physical and chemical methods, so as to achieve the purpose of removing all kinds of pollutants in sewage.
While Chengdu's sewer treatment facilities continue to improve, the improvement of the city's ecological environment requires continued efforts. In their daily lives, people should also pay attention to environmental protection, reduce wastewater discharges, strengthen sewage treatment and other aspects of advocacy, so as to *** with the creation of a cleaner, livable urban environment.
