Sewage purification flocculant

Abstract

The invention relates to the field of sewage purification and discloses a sewage purification flocculant which comprises 30-45% of iris ensata thumb fiber bundles, 5-12% of polyethylene pyridine, 0.4-0.9% of polyaluminum sulfate, 1.3-1.7% of magnesium hydrate, 11-15% of chitosan, 13-17% of bacillus subtilis and the balance of zeolite powder. The sewage purification flocculant is prepared by preteating the iris ensata thumb fiber bundles with hydrochloric acid, and further boiling and bleaching with a mixed liquid of an alkali, a bleaching agent, a surfactant and an accelerant for 6-8 hours. The sewage purification flocculant disclosed by the invention is used for providing microorganisms to degrade pollutants in sewage, moreover, undegraded pollutants, particularly heavy metals, can be flocculated, and the purpose of efficient water purification can be achieved.

Description

Technical field [0001] The invention relates to the field of sewage purification, and specifically discloses a sewage purification flocculant. Background technique [0002] The odor of water is the result of the anaerobic decomposition of organic matter in the water. The organic matter consumes a large amount of oxygen during the anaerobic decomposition process, causing the water to become hypoxic, causing anaerobic microorganisms to multiply and decompose to produce ammonia, hydrogen sulfide, etc. to escape the water surface And the lack of oxygen in the water body inhibits the growth and reproduction of beneficial microorganisms, aquatic animals and plants, and greatly weakens the aerobic effect of microorganisms. At the same time, it causes the reduction of heavy metals such as iron and manganese in the water, and the formation of ferrous sulfide with sulfur in the water makes the water appear black. [0003] There are chemical methods, bioreactor methods, filter membrane method...

AI Technical Summary

Problems solved by technology

[0003] There are chemical methods, bioreactor methods, membrane filtration methods, etc. for the purification of sewage, but the above sewage purification methods are not capable of treating heavy metals in reclaimed water, and cannot meet the current needs of sewage treatment.
