High-stability sewage treating agent and preparation method thereof

Abstract

The invention discloses a high-stability sewage treating agent and a preparation method thereof. The sewage treating agent comprises following materials by weight: 10-15 parts of citric acid, 50-70 parts of sodium carbonate, 10-15 parts of magnesium carbonate, 8-20 parts of ferric trichloride, 7-20 parts of calcium oxide and 10-15 parts of polyacrylamide. The preparation method includes uniformly mixing the materials in sequence and stirring. Compared with the prior art, the sewage treating agent and the preparation method has characteristics of multifunction, high efficiency, environment protection, high sewage treating speed, short treating time, capability of efficiently removing various pollutants and toxic materials with broad spectrum, high adaptability to high dirty concentration, wide pH value range and wide temperature change range of sewage, capability of effectively reducing odour of various types of sewage, high degree of alkalization, low corrosion, convenience for production, no pollution in production processes, simple product package, convenience for transportation, and low comprehensive cost.

Description

technical field [0001] The invention belongs to a sewage treatment agent 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 separate the first flocculants, corrosion inhibitors, fungicides and other agents in 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, it is the most widely used The common PAC (polyaluminum chloride) tablets have problems such as insufficient p...

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 separate different agents such as flocculants, corrosion inhibitors, and fungicides in 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 The common PAC (polyaluminum chloride) tablets have 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 same flocculant The effect in different sewage environments will vary greatly. Among them, the temperature, pH value and pollution concentration of the water body have the greatest influence on the flocculation effect. It is difficult for general flocculants to adapt to different sewage conditions. Therefore, in the process of sewage treatment, it is necessary to Check the water temperature and pH value at any time, and manually adjust it to the suitable range of the treatment agent to continue the reaction, resulting in complicated process flow and simple and cumbersome operation
