- Abstract:
- Tangjingsha River is the first river in Guangzhou to realize the separation of rainwater and sewage in the whole watershed. To eliminate river black and odor as the goal, to improve water quality as the core, to investigate the current situation as the basis, to separate clean water and sewage as the support, to construct pipe network as the guarantee, and to monitor the water quality as the starting point, nine technical routes are systematically formulated including source rainwater and sewage separation transformation, public sewage pipe network construction and improvement, wrong mixed connection transformation, drainage network disease repair, internal source reduction, non-point source treatment, pump station expansion and reconstruction, hydrodynamic improvement and ecological restoration. The specific treatment scheme and implementation content are elaborated. The implementation effect of the project is analyzed in combination with the measured water quality data after treatment and finally the treatment effect is reviewed and summarized. The engineering practice shows that the Tangjingsha River watershed treatment technology route is feasible and the effect is reliable for black and odorous water treatment, which can provide reference for the comprehensive treatment of water environment in other cities in China.
