Prechlorination synergist for source water

Abstract

The invention relates to a prechlorination synergist for source water whose components include potassium permanganate 60-75 wt%, aluminium sulphate 3-5 wt%, aluminium chloride 4-6 wt%, ferric chloride 4-6 wt%, ferrum sulphate 3-6 wt%, ferrous sulphate 4-6 wt%, manganese sulphate 6-9 wt%, organic macromolecular flocculating agent 1-2 wt%, wherein anionic polyacrylamide or non-ionic polyacrylamide can be selected as the organic macromolecular flocculating agent.

Description

technical field [0001] The invention relates to decontamination and purification treatment of source water, in particular to a prechlorination synergist for source water. Background technique [0002] At present, due to the discharge of urban sewage and industrial wastewater into rivers, a large amount of organic matter and nutrients enter the water body, resulting in eutrophication of the water body, especially lakes and reservoirs, and the proliferation of algae and odor. It has become a common water pollution. problem. [0003] When the urban water source is polluted, the waterworks often adopt the method of pre-chlorination, that is, adding chlorine to the water to purify the water. Acetic acid, etc., many of which have toxic effects on the human body, thus causing secondary pollution of water sources. Domestic studies have found that long-term drinking of chlorinated tap water will increase the risk of digestive and urinary system cancers. However, due to its suffici...

Problems solved by technology

[0004] Pre-ozonation, ozone-activated carbon and other advanced treatment technologies for source water are widely used abroad, but they require huge infrastructure, equipment investment and high operation investment. At the same time, ozone can also produce toxic substances or mutagenic substances. Tail gas treatment improper air pollution

[0005] One of the inventors once applied for a Chinese patent in 1993 on the relevant subject, and the title of the invention was "Permanganate Composite Agent Pollution Removal Technology for Drinking Water" and the application document publication number was CN 1103628A. The scope of the disclosure involved is quite different from that of the present invention, and the selected components are too complicated, and the content ratio of the components is not given, etc.
