Problems solved by technology

At present, the method of dosing, precipitation and filtration is mostly used for treatment, and the dosing is mostly polyaluminum. The common problem is that the treatment effect is not good, and the biochemical method is often used later.

Abstract

The invention discloses a sewage treating agent. The treating agent is characterized by comprising, by weight, 30% to 40% of polyacrylamide, 20% to 30% of carbon, 5% to 10% of tert-butyl hydroperoxide, 2% to 6% of ethylene diamine tetraacetic acid, 1% to 3% of potassium persulfate, 1% to 3% of dimethyl diallyl, 1% to 3% of mineral acid, and the balance water. The sewage treating agent has the advantages of being wide in application range, high in precipitation rate, low in treating cost, free from corrosion, toxicity and pollution, and safe in usage. The sewage treating agent can be widely applied to the sewage treatment of oil fields, coal mines, textile mills, printing and dyeing mills and the like.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an industrial sewage treatment agent. Background technique [0002] The chemical precipitation method is widely used in sewage treatment. It is to add some chemical agents to the waste water to make it chemically react with the pollutants in the waste water to form insoluble solid products, and then separate the solid and liquid to remove the water. A method of contamination. At present, the chemicals used in some industries, such as coal slime water, oily wastewater, printing and dyeing wastewater, papermaking wastewater, etc., have poor treatment effect, slow settling speed, high cost of chemicals, and some enterprises have caused serious corrosion of equipment. During the production of coal mines, a large amount of slime water is produced, and if the water is not treated in time, it will cause serious pollution. Existing coal slime water treatment method...
