Description
Technical Field
The invention belongs to the technical field of environmental protection, and particularly relates to a green alga and sludge recovery device.
Background
The water staying in a certain space for a certain time forms a lake, a marsh, a wet source and a river with slow flow rate, the concentration of nutrient salts in the water body is low at the initial formation stage, the growth and consumption of the water system are balanced, and the water system can be maintained in a stable state.
The eutrophication is usually derived from decayed plants, fertilizers used in farming lands, livestock excrements, and nitrogen, phosphorus and other nutrient components in synthetic detergents, and thus algae are likely to actively grow.
Meanwhile, with the rapid development of urban modernization and the continuous improvement of the living standard of people, a large number of urban sewage treatment plants are built and put into operation, which certainly plays a positive role in preventing and treating the water pollution problem in China, but a potential problem also arises, namely the problem of sludge treatment and disposal, the sludge is an accessory after sewage treatment, the increase of the sludge amount is inevitably caused due to the obvious increase of the sewage treatment amount, the sludge contains a large number of harmful substances (such as heavy metals), bacteria, various parasitic ova, a large number of pathogenic microorganisms and the like, and the large number of sludge not only influences the environmental sanitation, but also occupies a large area of land.
After sewage is discharged to an external water source, a large amount of green algae are generated in the water source due to eutrophication, the green algae not only can influence the growth and development of other organisms in the water, but also can influence the health of human beings through a food chain, the products of secondary metabolism of the green algae can damage the liver, have a cancer promotion effect, can directly threaten the health and survival of human beings, are lethal germs for part of fishes, and the 'bloom phenomenon' formed by the large amount of green algae can also induce the toxicity of nitrite and sulfide, can prevent toxic gas from escaping, deteriorate the water quality of the water body, emit fishy smell and influence the normal function of the water body.
At present, the traditional method for treating algae and sludge is to adopt purse seine manual ship salvage and ship suction cleaning to clear algae and purify sludge, namely, after pollutants such as algae are gathered by using the purse seine, the ship suction cleaning is to use a water pump suction filtration mode to recover sludge, and the method has low working efficiency and high labor cost. And adopt the water pump to inhale and filter this kind of method, because the debris such as pasture and water, branch exist in the water, easily block up the water pump, lead to the device fault rate to rise, the rate of recovery to reduce, simultaneously, a large amount of water in the recovery is retrieved together, still need to go through the process dehydration of secondary dehydration, can show improvement treatment cost.
