Sewage treatment agent

Abstract

The invention belongs to the field of sewage treatment and particularly relates to a sewage treatment agent which is prepared from natural mineral substances as well as a preparation method thereof. By controlling and changing the adding sequences of inorganic macromolecules and organic macromolecules with different functional groups, and the reacting and unreacting conditions in a compounding process, the good shape distribution and the stability of the inorganic macromolecules and the organic macromolecules before being added are kept, and the inorganic macromolecules and organic macromolecules are rapid in shape conversion and high-efficiency in flocculation after being added.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a sewage agent composed of natural minerals and a preparation method thereof. Background technique [0002] At present, the main treatment method for water pollution is chemical treatment, that is, water pollutants are treated by adding drugs. Due to the various and mixed types of water pollutants, and the main water treatment agents currently used have single functions, 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, the operation process is complicated, the dosage of chemicals is large, the cost is high, and various reagents will resist each other through various chemical reactions, resulting in a decrease in drug efficacy. Among the flocculants currently used for sewage treatment, they are the most widely used PAC (polyaluminu...

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, the operation process is complicated, the dosage of chemicals is large, the cost is high, and various reagents will resist each other through various chemical reactions, resulting in a decrease in drug efficacy. Among the flocculants currently used for sewage treatment, they are the most widely used PAC (polyaluminum chloride) generally has problems such as insufficient polymerization degree, weak flocculation and bridging ability, turbidity of effluent and unstable hydrolysis reaction. Different sewage environments will have a relatively large impact on flocculation. The effect of different sewage environments will vary greatly
