Problems solved by technology

The existing heavy metal sewage treatment machine still has many shortcomings, the treatment method is cumbersome, the treatment cost is high, and the cost is increased, and the water quality after treatment is poor, which cannot be recycled, and the extensive use of the existing sewage treatment agent is also harmful. Soil and water sources have caused some irreparable damage, which does not meet the requirements of green environmental protection

Abstract

The invention discloses a sewage treating agent for heavy metal pollution. The sewage treating agent is prepared from raw materials in parts by weight as follows: polyethyleneimine, carbon disulfide,sodium hydroxide, starch xanthate, bacillus mucilaginosus, concha haliotidis powder, modified zeolite powder, modified bentonite, sodium alginate, humic acid, ferric trichloride, nanometer titania, cellulose, ferrous sulfate, a photocatalyst, an efficient nickel remover, a chitosan modified polymeric flocculant, a coagulant aid, sephadex and deionized water. A preparation method of the sewage treating agent comprises steps as follows: material preparation, preparation of a mixed liquor A, preparation of a mixed liquor B and forming of the sewage treating agent. Through addition of polyethyleneimine, carbon disulfide and the coagulant aid, the sewage treating agent has a good flocculation effect on various heavy metal ions; through addition of starch xanthic acid, bacillus mucilaginosus, the concha haliotidis powder, the modified zeolite powder and the modified bentonite, the sewage treating agent has a good adsorbing effect, and the heavy metal ions in sewage are effectively removed bydouble cooperation of adsorption and flocculation.

Description

technical field [0001] The invention relates to the technical field of preparation of sewage treatment agents, in particular to a sewage treatment agent for heavy metal pollution. Background technique [0002] Heavy metal wastewater refers to wastewater containing heavy metals discharged from industrial production processes such as mining and metallurgy, machinery manufacturing, chemical industry, electronics, and instrumentation. Heavy metal wastewater mainly comes from wastewater discharged from mining, smelting, electrolysis, electroplating, pesticides, medicines, paints, pigments and other enterprises. The type, content and existing form of heavy metals in wastewater vary with different production enterprises. Heavy metal wastewater is one of the most serious environmental pollution and one of the most harmful industrial wastewater to humans, and its water quality and quantity are related to the production process. Heavy metals in wastewater generally cannot be decompo...
