- Abstract:
- Shanghai Disneyland comprehensive water treatment plant is the first comprehensive water treatment plant in China that simultaneously completes lake and irrigation water treatment. It operates in two modes: lake water internal circulation treatment and make-up water treatment. The main process of the comprehensive water treatment plant consists of biological aerated filter, sanding high efficiency sedimentation tank, filter, ultrafiltration and ultraviolet disinfection. During the afforestation irrigation, the comprehensive water treatment plant operates in make-up water treatment mode to make the closed Xingyuan Lake in an external circulation state through external consumption and external water replenishment. The combined treatment mode of lake water and irrigation water greatly reduces the total treatment scale and breaks the internal circulation closed state of the lake water. Years of operation show that the water quality of Xingyuan Lake and irrigation water meets the global Disneyland water quality standards and is much higher than the conventional domestic standards.
