Dongshan Lake Water Quality Improvement Project (secondary effluent standard)
Entering Guangzhou's famous Dongshan Lake Park, with lush green eyes, the mirror-like Dongshan Lake reflects the color of the sky. In the clear lake, the fish chased and played in the water and grass, watching along the lakeside path, and relaxing. As everyone knows, not long ago, the water quality was turbid. The Dongshan Lake water quality improvement project works mainly through comprehensive management of bottoms transformation, water grass domestication, water purification, ecological stocking, landscape effects, ecological cultivation, etc., and implements water body ecological restoration and waterscape construction on the water area of Dongshan Lake 335,000 square meters. Before October 31, 2017, the quality of Dongshan Lake was improved from surface water inferior to Class V to Class IV, and the water quality of Koi Lake had been raised to the regional water standard.
