- Abstract:
- By utilization of World Bank loan，black and odorous water of Zhuexi River was treated in two phases by wastewater interception, trenchless pipeline repair, dredging and removing silt, supplying water from natural environment, improving landscape, and implementing the River Chief System Management. Then, the target of eliminating the black and odorous water was gradually realized. The results of river water quality test in the second quarter of 2019 in Guangxi showed that, the average dissolved oxygen of all points of Zhuexi River was 3.97 mg/L, the average transparency was 31 cm, the average oxidation-reduction potential was 140.5 mV, the average ammonia nitrogen was 3.99 mg/L. The evaluation result of Zhuexi Rive was not black and odorous water. The implementation content and key points of the black and odorous water treatment project in Zhuexi River were introduced, and countermeasures and suggestions were put forward for the shortages of the project in order to provide reference for the black and odorous water management in other cities.
