Study on Water Pollution Control Technology for Dongda Reservoir Water Source Protection
Dongpu Reservoir and Dafangying Reservoir (hereinafter referred to as Dongda Reservoir) in Luyang District,Hefei,as important drinking water sources in Hefei,bear the important task of drinking water safety for many people in the urban area.In 2023,Dongda Reservoir Supplied more than 2 million m3 of water per day to Hefei urban area,and the daily water supply will continue to increase.However,with the increase of water supply,the water source protection area also has problems such as the difficulty of daily supervision of the water source,the unstable water quality of the main storage ditches,the incomplete collection and treatment of rural domestic sewage in the protection area,and the failure to achieve normalization of the ecological treatment project of the water source,which seriously threaten the water supply safety of the reservoir.To completely eliminate the above problems,the paper puts forward the corresponding control measures for the effective control of pollution sources in the basin where Dongda Reservoir is located.Through the implementation of these technical measures,the water supply safety of the reservoir can be effectively guaranteed,and finally the goal of supplying high-quality water source and ensuring the safety of cities and towns can be achieved.
