- Abstract:
- In recent years, the ecological protection of plateau lakes is becoming urgent with the rapid development of regional tourism. We expounded a new type of closed and full coverage sewage treatment system from farmers to sewage treatment plants taking Erhai Lake basin sewage treatment as an example, and discussed the problems in system design, construction, operation and maintenance, as well as optimized technology and strengthened technical measures. It was verified by the project that the protection and treatment of Erhai Lake basin have achieved phased results. In 2019, the water quality of Erhai Lake reached the class Ⅱ surface water standard in 7 months and class Ⅲ surface water standard in 5 months. The project not only effectively improved the water quality of Erhai Lake, but also achieved good social and economic benefits, and provided guidelines for the subsequent ecological treatment of plateau lakes.
