Industrial wastewater adsorbing agent

Abstract

The invention relates to an industrial wastewater adsorbing agent, which is prepared from the following ingredients in parts by weight: 8 to 14 parts of polyaspartic acid, 6 to 11 parts of amino trimethylene phosphonic acid, 5 to 8 parts of chitosan, 7 to 10 parts of 45-percent H2O2, 6 to 11 parts of acrylic acid macromolecule water-absorbent resin, 4 to 10 parts of maleic anhydride grafted polypropylene, 2 to 6 parts of PET (polyethylene terephthalate), 5 to 8 parts of hydroxyethyl methylacrylate, 4 to 10 parts of ethyl methacrylate, 1 to 3 parts of high-abrasion-resistant carbon black and 4 to 9 parts of hydroxyl cellulose solution. The industrial wastewater adsorbing agent has the beneficial effects that the industrial wastewater adsorbing agent has a good adsorption effect, can be used for removing suspended substances and a great number of toxic substances in the water, and cannot cause secondary pollution to the water quality.

Description

technical field [0001] The invention relates to an industrial waste water adsorbent. Background technique [0002] With the continuous improvement of human life, the eutrophication of water bodies such as ammonia nitrogen, phosphorus and other nutrient salts, and the step-by-step improvement of the sewage discharge standards of the National Environmental Protection Agency, industrial sewage discharge is currently the main source of pollution. The polluted water contains pesticides, heavy metal ions, radioactive elements and other substances that are harmful to humans, causing human diseases; at the same time, industrial wastewater generally contains a large amount of chemical toxic elements, which has a greater impact on the soil and the environment. However, the current net Generally, the main function of water materials is to control the formation of scale and sludge, reduce foam, and reduce corrosion of materials in contact with water. The current sewage treatment situati...

Problems solved by technology

The polluted water contains pesticides, heavy metal ions, radioactive elements and other substances that are harmful to humans, causing human diseases; at the same time, industrial wastewater generally contains a large amount of chemical toxic elements, which has a greater impact on the soil and the environment. However, the current net Generally, the main function of water materials is to control the formation of scale and sludge, reduce foam, and reduce corrosion of materials in contact with water. The current sewage treatment situation is not optimistic. Sewage treatment generally prevents heavy metal ions from being added to wastewater by adding reducing agents. Reduction to remove those metal ions that exist in the wastewater, iron powder, etc. are used as reducing agents, the material consumption is large, and it is easy to cause secondary pollution
