With the acceleration of urbanization, the construction of urban public toilets has become an important aspect of urban infrastructure construction. The construction of public toilets is of great significance to urban construction, improvement of environmental sanitation and improvement of people's living standards.

However, due to the frequent use of public toilets, sewage treatment is an important issue. At present, the Guangzhou municipal government has taken various measures to solve the problem of sewage discharge from public toilets. The sewage treatment of public toilets in Guangzhou is mainly divided into two ways, one is directly introduced into public sewage treatment plants, and the other is decentralized treatment.

Guangzhou Municipal Government has strengthened the monitoring and management of public toilet sewage that directly flows into public sewage treatment plants to ensure that the treatment effect meets the requirements. The decentralized treatment of public toilet wastewater mainly adopts biochemistry and membrane technology to ensure a high level of wastewater treatment, and the treated wastewater can be used for greening and irrigation.

Generally speaking, the sewage treatment of public toilets in Guangzhou has achieved remarkable results. The continuous improvement of sewage treatment facilities and a more perfect sewage management system will further guarantee the environmental sanitation and the quality of life of residents in Guangzhou.
