The system comprises a submersible sewage pump, an electromagnetic flowmeter, a pipeline mixer, a coagulation channel, a magnetic seed reaction chamber, a flocculation reaction chamber, a sedimentation tank, a vertical low temperature ionized water treatment unit, a first booster pump, a second booster pump, a coagulant soaking machine, a flocculant soaking machine, a first electromagnetic diaphragm metering pump, a second electromagnetic diaphragm metering pump, a mortar pump, a sludge shearer, a magnetic drum, a sludge concentration tank, a sludge dehydrator, a filtrate storage tank, a dryer, a biomass carbonization furnace, a cooling device, a sewage pipeline, a circulating water pipeline, a medicating pipeline and a sludge pipeline; the method comprises sewage coagulation, sewage magnetization, sewage flocculation, sewage separation, water body purification, sludge shear, magnetic powder separation, sludge concentration, sludge dehydration, sludge drying, sludge carbonization and biomass carbon collection. Closed ring system design is adopted, and system functions are subjected to coordination control by a series connection-parallel connection process.

Description

technical field [0001] The invention relates to a water body purification system, in particular to a magnetic separation water body purification system and a separation and purification method thereof. Background technique [0002] China is short of water resources and is one of the 13 water-scarce countries in the world. About half of the 670 cities in the country are currently short of water, and the water pollution is serious. The urban waters in China are seriously polluted, and 60%-70% of the total water shortage in southern cities is caused by water pollution. my country's water pollution mainly comes from industrial wastewater discharged beyond the standard, and a large amount of urban domestic sewage that directly enters the water body without treatment. Urban domestic sewage is becoming one of the biggest "public hazards" of water pollution. Therefore, the treatment of urban domestic sewage is of great significance for improving the quality of urban environment and...

AI Technical Summary

Problems solved by technology

[0004] At present, there are only a handful of technologies successfully developed at home and abroad that use magnetic separation water purification systems to treat sewage, and they all use conventional gravity sedimentation methods for mud-water separation. However, most of the existing magnetic separation water purification systems adopt open-loop design, and the degree of equipment integration is low. , low utilization rate of magnetic species, poor impact load resistance, and high operating costs; at the same time, the existing magnetic separation water purification system does not integrate a thorough sludge treatment process, which leads to an increase in sludge treatment sites and operating costs for users
