- Abstract:
- Compared with the development of the city, the drainage system construction is delayed. Moreover, with large quantity of regional pollution discharge, the Maozhou River basin in Shenzhen had been severely malodorous for a long time. After the first round of water environment comprehensive improvement launched in 2016, the stage goal of preventing sewage from discharging into the river during the dry season was achieved. However, problems such as river pollution during the rainy season, and the sewage system defects still existed. For the long-term cleanliness, it has launched the second phase of drainage system upgrading and perfection. The project was organized according to the investigation of “plant-network-source-river” in the basin, and the countermeasures including rainwater and sewage collection improvement from the sources, transmission system upgrading and the sewage treatment plants connection were proposed. The practice indicated that the stable up-to-standard water quality in the basin and the increase of wastewater concentration in the wastewater treatment plant were achieved. It provided a helpful reference for similar projects.
