Abstract

The invention discloses a composite sewage treatment material, which is prepared from the following raw materials by weight: 12-20 parts of macroporous adsorption resin, 5-8 parts of silica, 3-5 partsof attapulgite, 7-11 parts of ferrous chloride, 14-22 parts of bentonite, 8-11 parts of sodium fluorosilicate, 5-10 parts of porous starch, 2-5 parts of tourmaline, 8-11 parts of ammonium persulfate,0.2-0.8 parts of ethanolamine, 10-20 parts of corn cob and 0.5-1 part of magnesium aluminosilicate. The invention also discloses a preparation method of the composite sewage treatment material. The composite sewage treatment material has good mechanical strength and large specific surface area by composite of the macroporous adsorption resin and the silica, and has good purification sewage performance, good treatment effect and high speed, is capable of flocculating and adsorbing larger particles in sewage, at the same time reduces metal ions, and is low in cost of use.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a composite sewage treatment material and a preparation method. Background technique [0002] With the rapid development of industry and agriculture, the problem of water pollution is becoming more and more serious, which directly threatens the sustainable development of human health and social economy. The quality of water directly affects the environment and people's health, especially organic pollutants, which accelerate the growth and reproduction of algae in the water and accelerate the deterioration of the water. The existing industrial and urban wastewater treatment methods include physical treatment, chemical treatment and biological treatment. Among them, the chemical treatment method is to use treatment agents to treat pollutants, but the treatment efficiency is low, and it is difficult to meet the emission standards. [0003] The existing sewage treatment ma...
