Sewage treatment agent

Abstract

The invention discloses a sewage treatment agent, which mainly comprises the following raw materials in weight part: 15-30 parts of aluminum sulfate, 15-30 parts of ferric sulfate, 1-5 parts of polyacrylamide, 1-5 parts of microorganisms, 15-30 parts of potato starch, 3-13 parts of sodium polyacrylate, 7-17 parts of bentonite, 5-10 parts of tannin, 4-11 parts of potassium permanganate and 20-40 parts of modified vesuvianite. The sewage treatment agent is wide in the source of raw materials, and can effectively remove pollutants in water. Meanwhile, by means of the sewage treatment 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

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...
