Abstract

The invention discloses a sewage filter material and a preparation method of the sewage filter material. The sewage filter material comprises, by weight, 7-11 parts of styrene sulfonic acid, 20-30 parts of silica gel, 8-20 parts of polyacrylamide, 5-8 parts of dimethyl malonate, 7-14 parts of azodicarbonamide, 10-18 parts of nano-modified activated carbon, 10-15 parts of zeolite, 5-8 parts of straw fibers, 2-6 parts of alum and 0.8-2.0 parts of sepiolite. According to the preparation method of the nanometer modified active carbon, bamboo charcoal and titanium dioxide are mixed for modification, then polyepichlorohydrin and ethyl acetate are added, and the nanometer modified active carbon is obtained after stirring and drying. By the adoption of the sewage filter material and the preparation method, the physicochemical indexes of seriously-contaminated sewage are made to reach the GB18918-2002 standard; and the treatment process is simple, the dosage is small, the treatment effect is good, the performance is stable, the cleaning degree of the contaminated sewage is high, the cost of the treatment agent can be reduced effectively, and the sewage filter material and the preparation method have the very good economic benefits and a wide range of social benefits.

Description

technical field [0001] The invention relates to the technical field of sewage, in particular to a sewage filter material and a preparation method thereof. Background technique [0002] The industrial development in the last century brought a dramatic increase in population. caused a sharp deterioration of the current environment. In the 21st century, mankind is facing many crises, and the shortage of water resources is the biggest crisis facing mankind. The shortage of water resources has intensified, and the problem of water pollution has become increasingly serious and continuously threatens human beings. In order to solve this crisis, scientists from all over the world are looking for effective methods and ways to obtain pure water resources. Desalination of seawater and reuse of sewage treatment are two effective methods. At present, many countries have obtained pure drinking water and domestic water through seawater desalination technology. Thus partially solving t...
