Problems solved by technology

At present, flocculants are mainly divided into two categories: inorganic flocculants and organic flocculants. Inorganic flocculants have strong applicability to water treatment of various complex components, but the flocs produced are relatively small, with poor settling properties, large dosage, and cost of chemicals. Relatively high; compared with

Abstract

The invention discloses a water body heavy metal ion pollution flocculation sediment preparation and a preparation method thereof. The water body heavy metal ion pollution flocculation sediment preparation is prepared from the following raw materials in parts by weight: 18 to 26 parts of sodium methallyl sulfonate/acrylamide/acrylic copolymer, 15 to 20 parts of sulfonated styrene-maleic anhydridecopolymers, 13 to 19 parts of 2-amino-3-mercaptoyl chitosan, 5 to 10 parts of hydroxyethylenediamine trisodium triacetate, 16 to 22 parts of polymeric aluminum ferric biacid, 6 to 12 parts of sodium alginate sulfate, 4 to 8 parts of starch xanthate, 14 to 21 parts of alum, 3 to 6 parts of tetradecylpyridinium chloride, 5 to 10 parts of Pulullan, 2 to 5 parts of guar hydroxypropyltrimonium chloride, 1 to 4 parts of behentrimonium methosulfate, 17 to 24 parts of beidellite and 15 to 20 parts of amblygonite. The prepared water body heavy metal ion pollution flocculation sediment preparation has the advantages that the flocculation effect is good; the settlement separation is fast; the efficiency is high; the chemical adding quantity is small; the applicable water quality range is wide; organic matters and various heavy metal ions in the water body can be effectively eliminated; certain sterilization, disinfection and decoloring capability are realized.

Description

field of invention [0001] The invention relates to a flocculation deposition preparation and a preparation method thereof, in particular to a water heavy metal ion pollution flocculation deposition preparation and a preparation method thereof. Background technique [0002] Heavy metal wastewater mainly comes from mechanical processing, non-ferrous metal smelting, electroplating, leather processing and some chemical companies. Heavy metal ion pollutants usually have acute or chronic toxicity and cannot disappear through self-purification, but can be enriched through the biological food chain, thereby endangering human health. Water pollution by heavy metal ions has become one of the most serious environmental problems in the world. There are many methods for treating heavy metals in wastewater, including flocculation, adsorption, chemical precipitation, and electrochemical methods. [0003] Flocculation plays an important role in water treatment research at home and abroad....
