Environment puricant and using method thereof

Abstract

The invention discloses an environment puricant and a using method thereof. Aluminum sulfate in the environment puricant is used for settlement of suspended matters in sewage, a polyacrylamide hydrolysis product is used for flocculation of impurities, ferrous sulfate is used as a settling promoter, the polyacrylamide hydrolysis product has a stronger nucleation function, and then the aluminum sulfate and the ferrous sulfate are matched, so that not only the nucleation effect is increased, but also the dehydration speed during a flocculation process is greatly increased, and quick dehydration of sludge and other suspended particles in the sewage can be effectively promoted; a water treatment aid is prepared from anhydrite, slaked lime, sodium carbonate, cement, sodium thiosulfate, silicon dioxide and sodium hypochlorite, so that not only bacteria and viruses in the sewage and solid matters can be effectively killed, but also rapid moisture absorption, dehydration and separation can be carried out on water in concentrated sludge, the water can be conveniently separated from the solid matters, the solid matters obtained through separation have stronger hydrophobicity, the separated solid matters are in dry pasty shapes, the solid matters are low in water content and very good in mechanical performance.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an environment purifying agent and a using method thereof. Background technique [0002] Due to the constant changes in climate and address movement, under the action of river and coastal tides, fine rocks and soil particles will deposit and settle to form soft soil layers in slow-flow areas such as river channels, seaports, reservoirs, lakes, etc. And industrial pollutants are carried and mixed to form a wet and soft concentrated sludge layer. [0003] The traditional solidification treatment method for solids in concentrated sludge generally adopts the method of adding a large amount of cement series or lime series products for hydrolysis reaction and fixing them. Generally, cement is used when the objects to be treated are mostly inorganic substances. series, lime series products are used when the objects to be processed are mostly organic matter. The water treatment...

AI Technical Summary

Problems solved by technology

The water treatment of cement series or lime series is mainly based on the self-hardening reaction of absorbing water, and the amount of addition is determined according to the water content of the treatment object; usually 30-40% of the addition amount is required, and the amount of environmental purifier used is too large; concentration Another method of sludge dehydration is to use a dehydrator, but the use of a dehydrator to concentrate sludge not only requires a large amount of environmental purifiers, but also has problems such as dehydration difficulties; Afterwards, it is almost pasty, and the water content of the concentrated sludge is as high as 95%~97%, which makes the volume of the concentrated sludge too large and occupies a large area, which increases the transportation cost of the concentrated sludge
