- Abstract:
- The construction of intercepted drainage system is an important technical method to solve the problem of black and odorous water. However, it will lead to the low influent concentrations in wastewater treatment plant and severe sewage overflow in rainy days. Taking the area of Yangli sewage treatment plant in Fuzhou City as an example, this paper described the main problems of the intercepted drainage system, and put forward suggestions and improvement measures. Implementation measures that proved to be effective were introduced from three aspects of “intercepting system, municipal drainage system, community source drainage system”. After reconstruction, the concentration of BOD5 in Yangli sewage treatment plant increased by 12%-26%, and the total amount of pollutants collected by the sewage system increased by 29%-53%. This project provides a successful case and reference for improving the efficiency of urban sewage treatment and consolidating the effectiveness of urban river treatment in other cities.
