Abstract

The invention discloses a sewage adsorbent. The sewage adsorbent is mainly prepared from, by weight, 25-35 parts of sodium bentonite, 12-20 parts of sodium acetate, 5-8 parts of xylene, 2-8 parts of sorbide trioleate, 17-24 parts of nano modified activated carbon, 0.7-1.3 parts of polyoxyethylene ether series surfactant, 8-12 parts of sodium polyacrylate and 0.8-2.0 parts of stearate; the preparing method of the nano modified activated carbon comprises the steps of conducting ultrasonic impregnation on activated carbon by adopting nitric acid, magnesium acetate, polyurethane and sodium alginate, and performing drying to obtain the nano modified activated carbon. Through the sewage adsorbent, physicochemical indexes of sewage which is seriously polluted can reach GB18918-2002 standard; the treatment technology is simple, the dosage is little, the treatment effect is good, the performance is stable, the recovery degree of the polluted sewage is high, the cost of treating agents can be effectively reduced, and the sewage adsorbent has good economic benefits and wide social benefits.

Description

technical field [0001] The invention relates to the technical field of sewage, in particular to a sewage adsorbent. Background technique [0002] Industrial development in the last century brought about a sharp 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 the water crisis. However, if the proble...
