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, 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

Abstract

The invention belongs to the field of polluted water treatment, and particularly relates to a preparation method for a polluted water treatment agent made from natural minerals. By means of controlling and changing the adding sequence of inorganic polymer substances and organic polymer substances in different functional groups and under reaction and non-reaction conditions during compositing, good form distribution and stability of the components can be kept before being added, so that the components are quite fast in form transformation and have high-efficiency coagulated flocculability after being added.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a preparation method of a sewage agent composed of natural minerals. 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 (polyaluminum chlorid...
