Problems solved by technology

Due to the various and mixed types of water pollutants, and the main water treatment agents currently used have a single function, it is necessary to add flocculants, corrosion inhibitors, fungicides and other agents to the water treatment system, and the treatment process is complicated.
There are a lot of equipment, complicated operation process, large amount of dosage and high cost, and various reagents will resist each other through various chemical reactions, resulting in a decrease in drug efficacy.
However, the existing water treatment agents often have weak adsorption capacity for some heavy metal ions.

Abstract

The invention discloses a sewage treating agent, which mainly comprises the following raw materials in weight part: 15-30 parts of polymerized aluminium chloride, 15-30 parts of ferric sulfate, 1-5 parts of polyacrylamide, 1-5 parts of microorganisms, 15-30 parts of corn starch, 3-13 parts of sodium polyacrylate, 7-17 parts of bentonite, 5-10 parts of tannin, 4-11 parts of potassium permanganate, 20-40 parts of modified vesuvianite, 10-20 parts of citric acid, 10-20 parts of activated carbon, 10-25 parts of polymerized ferric chloride, and 5-20 parts of sodium acetate. The sewage treating agent is wide in the source of raw materials, and can effectively remove pollutants in water. Meanwhile, by means of the sewage treating agent, the sewage can be completely treated, and the treatment cost is low. Moreover, the sewage treating agent is free of poison and pollution. The treated sewage can meet the requirements of a national comprehensive sewage drainage standard.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a wastewater treatment agent. Background technique [0002] Wastewater refers to the general term for water discharged during residents' activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other useless water such as primary rainwater that flows into drainage pipes and canals. It generally refers to water that cannot be recycled after certain technical treatment or that is difficult to purify after primary pollution and cannot meet a certain standard. With the rapid development of my country's chemical industry, various new chemical products are applied to all walks of life, especially in heavy polluting industries such as medicine, chemical industry, electroplating, printing and dyeing. Industrial wastewater flows directly into channels, and rivers and lakes pollute surface water. If it is highly toxic, it will lead to the death or even e...
