Problems solved by technology

[0003] At present, there are many methods such as physics, chemistry, biology, and comprehensive methods to deal with water resource pollution. However, most of the physical methods have problems of poor treatment effect and unstable treatment rate, and the cost of biological methods is too high. Chemical methods are used to treat sewage, but the existing sewage treatment agent, as the name suggests, is an additive that needs to be used in sewage treatment, but the existing sewage treatment chemical reagents have secondary pollution and endanger the environment

Abstract

The invention discloses and provides a chemical reagent for wastewater treatment; wastewater is treated by means of flocculating, coagulation enhancement, conditioning, defoaming, and sterilizing, inorganic and organic components cooperate to act as a coagulant, and therefore the chemical reagent has excellent flocculating effect. The chemical reagent has the advantages of high purifying speed, good effect, good environmental friendliness, low toxicity and the like, is low in production cost and is suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a chemical reagent for sewage treatment. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] At present, there are many methods such as physics, chemistry, biology, and comprehensive methods to deal with water resource pollution. However, most of the physical methods have problems of poor treatment effect and unstable treatment rate, and the cost of biological methods is too high. Chemical methods are used to treat sewage, but the existing sewage treatment agent, as the name sug...
