Material used for purifying wastewater from chemical industry

Abstract

The invention discloses a material used for purifying wastewater from chemical industry. The material comprises, by weight, 9 parts to 17 parts of concentrated hydrochloric acid, 3 parts to 10 parts of kieselguhr, 7 parts to 9 parts of conch shell powder, 2 parts to 7 parts of soybean molasses, 3 parts to 11 parts of sodium humate, 2.4 parts to 8 parts of actinomyces, 2 parts to 6 parts of rare earth, 6 parts to 14 parts of nanometer titania, 3 parts to 9 parts of polyethylene glycol serving as slow-release agents, 1.2 parts to 5 parts of activated aluminum oxide, 2 parts to 5 parts of golden cypress wood, 6 parts to 13 parts of sodium dodecyl benzene sulfonate, 4 parts to 9 parts of ethyl alcohol, 6.5 parts to 11 parts of chlorine dioxide, 9 parts to 16 parts of pine wood and 5 parts to 8 parts of surface active agents. The material used for purifying the wastewater from the chemical industry has the advantages that eutrophication of the water can be reduced, toxic and harmful substances in the water can be adsorbed, particles suspended in the water can be flocculated, and the water quality can be improved.

Description

technical field [0001] The invention relates to a chemical wastewater treatment material. Background technique [0002] Chemical wastewater is the process wastewater, cooling water, waste washing water, equipment and site washing water and other wastewater discharged in chemical production. If the waste water is discharged without treatment, it will cause different properties and different degrees of pollution of the water body, thereby endangering human health and affecting industrial and agricultural production. Chemical wastewater pollution has the following characteristics: 1. Toxic and irritating. Some chemical wastewater contains toxic or highly toxic substances such as cyanide, phenol, arsenic, mercury, cadmium or lead, which have toxic effects on organisms and microorganisms at a certain concentration. In addition, it may also contain irritating and corrosive substances such as inorganic acids and alkalis. 2. High concentration of organic matter. In particular, t...

AI Technical Summary

Problems solved by technology

2. High concentration of organic matter

[0003] 3. The pH is unstable

4. More nutrients

Wastewater with high phosphorus and nitrogen content will cause eutrophication of the water body, causing algae and microorganisms to multiply in the water, and in severe cases, it will cause "red tide" and affect the growth of fish

5. Recovery is more difficult

Especially the heavy metals concentrated by microorganisms, it is still difficult to eliminate the discharge
