Abstract

The invention discloses a sewage treatment agent, which is prepared from the following raw materials: organic carboxylic acid, modified sisal fiber porous microspheres, polyamino acid, starch xanthateand aminotris(methylenephosphonic acid). A preparation method of the sewage treatment agent comprises the following steps: preparing the modified sisal fiber porous microspheres; adding organic carboxylic acid and polyamino acid into the citric acid modified sisal fiber crosslinked chitosan porous microspheres, fully and uniformly mixing, adding the starch xanthate and the aminotris(methylenephosphonic acid), and fully and uniformly mixing again to obtain the sewage treatment agent. According to the sewage treatment agent disclosed by the invention, through compounding of the raw materials, asynergistic effect is achieved, various metal ions in a water body can be captured, and meanwhile, the sewage treatment agent also has remarkable corrosion and scale inhibition effects, so that scaling and corrosion of a system can be effectively reduced, and the production cost is reduced; the treated sewage can reach the discharge standard, the flocculation strength is high, and the hydrophobicproperty is good; and the treated water has no problems of secondary pollution and the like.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment agent. Background technique [0002] my country is a country with a shortage of water resources, and the distribution of water resources is seriously uneven. How to alleviate the shortage of water resources and pollution has become an urgent problem. In order to solve the problem of water shortage, in addition to increasing sources of income, reducing expenditure, and comprehensive utilization, pollution control has gradually become one of the basic principles that our country must adhere to for a long time. [0003] At present, there are three common methods of heavy metal wastewater treatment: the first category is the method of removing heavy metal ions in wastewater through chemical reactions, including neutralization precipitation method, sulfide precipitation method, ferrite co-precipitation method, chemical reduction method, Electrochemical red...
