The invention provides a process system and method for deep purification of eutrophic water body, which is mainly composed of four parts connected in sequence: a pretreatment unit, an algae removal unit, a floating bed purification unit and a coagulation purification unit. Algae density on-line monitors, ammonia nitrogen concentration on-line monitors and turbidity on-line monitors are installed at the front end of the algae removal unit, floating bed purification unit and coagulation purification unit respectively, and the operating parameters of the main purification devices of each unit are adjusted according to the change of the influent index Or perform transcendence diversion, which can realize the dynamic control of the deep purification process system of eutrophic water body. On the premise of ensuring the stable removal of main water index pollutants such as algae density, ammonia nitrogen, and total phosphorus, it reduces energy consumption and operating costs, and effectively improves the efficiency of deep purification. At the same time, the system has a short hydraulic retention time, which is especially suitable for landscape or ecological utilization after large-flow purification and regeneration of urban eutrophic water bodies.
Description
technical field [0001] The invention relates to the technical field of eutrophic water treatment, in particular to a process system and method for deep purification of eutrophic water. Background technique [0002] The eutrophication of rivers and lakes in the lower reaches of the city has seriously affected the urban landscape and the lives of surrounding residents, forming a bottleneck that restricts the image and development of the city. Therefore, the deep purification of eutrophic water body can not only reduce the nutrient load of the water body, but also use the purified water for landscape and ecological replenishment, forming a double-line virtuous cycle of water quality and hydraulic power. [0003] Compared with general urban sewage, eutrophic water body has pollution characteristics such as low pollution concentration, low C / N ratio, high nitrogen and phosphorus content, and easy algae breeding. Therefore, its water body treatment belongs to the category of deep ...
