Abstract

The present invention discloses a sewage adsorbent and a preparation method thereof, wherein the main raw materials of the sewage adsorbent comprise, by weight, 25-35 parts of sodium-based bentonite, 12-20 parts of polyacrylamide, 5-8 parts of polyvinylpyrrolidone, 2-8 parts of sorbitan trioleate, 17-24 parts of nanometer modified active carbon, 0.7-1.3 parts of a polyoxyethylene ether-based surfactant, 8-12 parts of polyaluminum chloride, and 0.8-2.0 parts of stearate, and the nanometer modified active carbon preparation method comprises: carrying out ultrasonic wave impregnation on active carbon by using nitric acid, magnesium acetate, polyurethane and sodium alginate, and drying to obtain the nanometer modified active carbon. According to the present invention, with the sewage adsorbent, the physical and chemical indexes of the seriously polluted sewage can achieve the GB18918-2002 standard; and the sewage adsorbent has advantages of simple treatment process, less consumption, good treatment effect, stable performance, high polluted-sewage recovery degree, effectively-reduced treatment agent cost, 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 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 the wat...
