Embodiment 1

[0018] Mix solid sodium chlorite, ferric sulfate, borax and itaconic acid uniformly in a certain proportion to obtain the reaction composite multifunctional water treatment agent of the present invention. When in use, according to the water quality, add it to the water to be treated in a certain proportion, and at the same time stir rapidly for 3-5s to make the medicine and water fully mixed, then stir slowly (about 20-30min), and finally let it stand for 30-60min , the supernatant is the treated water. The water treatment effects in both cases are as follows:

[0019] A same medicament formula——sodium chlorite: ferric sulfate: borax: itaconic acid=1:1:0.015:0.07 weight ratio, and the dosage of medicament is different.

Abstract

The invention provides a reactive compound multi-functional water treatment agent and a preparation method and an application method thereof. The multi-functional water treatment agent comprises the following components sodium chlorite, ferric sulphate, borax and itaconic acid, wherein the weight ratio of the components is 1: 0.8-1.5:0.01-0.03:0.05-0.1. The agent is used in waste water, the components react with each other, the reaction products or the intermediate products thereof have the functions of sterilization, flocculation and adsorption; by combining with the compound effect of othercomponents, the water treatment agent of the invention can enjoy quadruple functions of sterilization, flocculation, adsorption and scale inhibition at the same time.

Description

technical field [0001] The invention provides a reaction composite multifunctional water treatment agent and its preparation method and application method. Background technique [0002] Flocculation is an ancient water treatment method with a long history. Flocculant plays a very important role in wastewater treatment. It can be used to reduce sensory indicators such as turbidity and chromaticity of raw water, and remove various high-molecular organic substances, some heavy metals and radioactive substances. It can be treated independently The system can be combined with other treatment unit processes as a pretreatment, intermediate treatment and final treatment process, and is often used in the thickening process before sludge dewatering to improve the dewatering performance of sludge. At present, domestic industrial water supply, urban water supply, and sewage treatment demand millions of tons of flocculants every year, so it is of great significance to study flocculants....
