Abstract

The invention relates to an environment-friendly flocculant with a natural high polymer as a major component and belongs to the technical field of water treatment flocculants. The flocculant is prepared from the following components in parts by weight: 60-75 parts of chitosan-lignin or chitosan-fulvic acid grafted copolymer, 15-30 parts of carboxymethyl starch, 5 parts of montmorillonite and 5 parts of activated carbon. The flocculant is mainly prepared from natural high polymers and has the characteristics of environmental protection and no secondary pollution; and besides, the flocculant is low in price, high in removal rates of heavy metal ions and organic pollutants, and high in flocculating and settling speeds.

Description

technical field [0001] The invention relates to an environment-friendly flocculant mainly composed of natural polymers, belonging to the technical field of flocculants for water treatment. Background technique [0002] Under the highly developed modern civilization, industrial wastewater and urban sewage are increasingly harmful to the environment. Prevention and control of industrial waste water and urban sewage pollution has become a common concern of the people. Years of research and practice have shown that adding flocculants to coagulate pollutants in sewage is one of the generally effective methods, and it has the characteristics of simple process and low cost. At present, the flocculants commonly used in the industry mainly include inorganic and organic flocculants, and there are many varieties. The price of inorganic flocculant is low, but the dosage is high. Organic synthetic polymer flocculants are used in small amounts and have good flocculation effects, and ar...
