Problems solved by technology
Heavy metals cannot be biodegraded, but they are bioaccumulative and can directly threaten higher organisms including humans. Relevant experts pointed out that heavy metal pollution to soil is irreversible, and the contaminated soil has no treatment value, and can only be avoided by adjusting planting varieties

Abstract
The invention relates to a heavy metal sewage treatment agent which is prepared from dodecyl diethylene triamine, dimethyl diallyl ammonium chloride, acrylamide, dibenzoyl peroxide, powdered activated carbon, ethylene diamine tetraacetic acid, tert-butylamine, carbamate, dithiocar-bamate, thiocarbamic acid ester, starch, cellulose, water soluble starch xanthate ester, sodium silicate, potassium peroxodisulfate, sodium hydrosulfite, strong base and water. The heavy metal sewage treatment agent disclosed by the invention is formed by being modified with a high-molecular compound; the mixture contains a plurality of active groups which can be complexed, chelated, absorbed and exchanged with heavy metal, so that heavy metal ions in the aqueous solution can be removed; the heavy metal sewage treatment agent has good removal effect on heavy metal ions, the removal rate is above 97%, and furthermore, the heavy metal sewage treatment agent has stronger Ca2+ and Mg2+ resistant capability; the removal rate of cadmium-containing sewage is 99.8%, which meets the national emission standard; and the removal rate of chromium-containing sewage is above 99.6%.
Description
technical field [0001] The invention relates to a heavy metal sewage treatment agent, which belongs to the technical field of sewage treatment. Background technique [0002] 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. Since heavy metals cannot be decomposed and destroyed, they can only transfer their existing positions and change their physical and chemical forms. [0003] Heavy metal pollution is different from pollution from other organic compounds. Many organic compounds can reduce or eliminate their harmfulness through physical, chemical or biological purification of nature itself. Heavy metals are enriched and difficult to degrade in the environment. At present, due to the mining, smelting, and processing of heavy metals in o...
