CN105621558A - Novel sewage treatment agent - Google Patents

Abstract

The invention relates to a chemical reagent and particularly relates to a novel sewage treatment agent for sewage treatment. The novel sewage treatment agent is prepared from the following ingredients in parts by weight: 25-35 parts of composite iron, 15-20 parts of polyacrylamide, 8-12 parts of polyaluminum chloride, 30-43 parts of bentonite and 3-5 parts of heavy-metal precipitant. According to the novel sewage treatment agent, the selected composite iron is readily soluble in water, the coagulation effect is excellent, the product stability is good, the applicable pH value range is wide, and the pH of treated water is not greatly lowered; meanwhile, inorganic and organic ingredients serve as a coagulant in a synergistic manner, so that the novel sewage treatment agent has an excellent flocculation effect; and the novel sewage treatment agent has the advantages of high purifying speed, good effect, environment-friendliness, no toxicity and the like.

Description

A kind of novel sewage treatment agent

Technical field

This invention belongs to industrial chemical, environmental technology field.

Background technology

Along with people's raising to water quality requirement, our factory, according to various places, China north and south, the erosion of high temperature height, the low erosion of low temperature, the raw water quality monitoring files containing algae and trace level chemical substance of holding concurrently, special invents this patent.

Summary of the invention

The present invention relates to a kind of chemical reagent, relate particularly to the novel sewage-treating agent of a kind of sewage disposal aspect. The present invention is formed by the configuration of following ratio of weight and number, compound iron 25 35; Polyacrylamide 15 20; Aluminium polychlorid 8 12; Bentonite 30 43; Heavy metal precipitator: 3-5. The deficiencies such as the compound iron coagulation effect soluble in water that the present invention selects is excellent, product stability is good, are suitable for pH value range wide, and after process, the pH of water reduces little, the present invention has the effect of the flocculation of excellence, the advantages such as it is fast that the present invention has purification speed, effective, environment-protecting asepsis.

Detailed description of the invention

1. scheme one: by compound iron 25; Polyacrylamide 15; Aluminium polychlorid 12; Bentonite 43; The ratio of heavy metal precipitator 5 is mixed to get.

2. scheme two: by compound iron 35; Polyacrylamide 20; Aluminium polychlorid 8; Bentonite 30; The ratio of heavy metal precipitator 3 is mixed to get.
