Problems solved by technology

At present, the common water treatment agent has a single function, so it is necessary to add various agents such as flocculants, corrosion inhibitors, and oxidants in the water treatment system. Reagents are prone to chemical reactions and mutual resistance during the addition process, resulting in reduced efficacy

Abstract

The invention discloses a novel sewage treatment agent and a preparation method thereof. The treatment agent is prepared from components in a raw material formula in parts by weight as follows: 20-30 parts of yeast powder, 20-30 parts of polyethyleneimine, 15-25 parts of polyaluminum chloride, 12-18 parts of silica, 2-6 parts of hydrogen peroxide, 1-4 parts of gum and 1-4 parts of an acidity regulator. The method comprises preparation steps as follows: the yeast powder and polyethyleneimine are weighed, mixed and stirred, a mixture is crushed, crushed powder is dried and left to stand, silica, polyaluminum chloride and the gum are added sequentially while stirring, the solid acidity regulator is added after even stirring, and solid hydrogen peroxide is slowly added and slightly stirred to be even. With the agent, physical and chemical indexes of treated sewage can reach the standard GB18918-2002, COD (chemical oxygen demand), BOD (biochemical oxygen demand) and TOC (total organic carbon) are effectively reduced, the method is simple to operate, and all agents are free of chemical reactions.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a novel sewage treatment agent and its application method. Background technique [0002] Water is one of the most indispensable material resources for the survival and development of human beings. With the rapid acceleration of urbanization and the improvement of people's living standards, the amount of various wastewater such as industrial wastewater and domestic sewage is huge. , The growth rate is astonishing. According to incomplete statistics, my country produces hundreds of millions of tons of industrial wastewater with high heavy metal content every year, among which organic pollutants and heavy metals, such as phenols, dyes, cadmium, chromium, mercury, etc. often contain highly toxic, which makes the water environment in the area heavily polluted. At present, the common water treatment agent has a single function, so it is necessary to add various agents such as...
