Problems solved by technology

[0004] Traditionally used detergents include bleaching powder, bleaching essence, copper sulfate, bromogeramine, etc., but most of these detergents are strong acids, strong alkalis and other components, which are highly corrosive, volatile, difficult to operate, and time-consuming. It will adversely affect the physical and mental health of the operators, and the cleaning effect is poor, the cleaning time is long, and the cleaning efficiency is low, which ultimately affects the production operation

Abstract

The invention provides a sewage treatment agent and a preparation method of the sewage treatment agent. The sewage treatment agent comprises the following components: 20 to 30 parts of modified diatomite, 20 to 40 parts of medical stone, 20 to 30 parts of slag, 20 to 30 parts of sodium lignosulfonate, 10 to 15 parts of chitosan, 10 to 20 parts of seabed mineral mud, 5 to 10 parts of polymeric silicate aluminum sulfate, 10 to 20 parts of polyferric chloride, 10 to 20 parts of phosphonate, 10 to 20 parts of ethylenediamine tetramethylene phosphonic acid, 10 to 20 parts of microbial agents and 100 to 160 parts of deionized water. The treatment agent disclosed by the invention can effectively adsorb particles in sewage, and further remove pathogenic bacteria and heavy metals in the sewage.

Description

Technical field [0001] The invention belongs to the technical field of treatment agents, and specifically relates to a sewage treatment agent for treating domestic sewage and a preparation method thereof. Background technique [0002] Sewage treatment plants are the main function bearers of water pollution control and play a key role in purifying water pollution. As of the end of 2014, nearly 4,000 urban sewage treatment facilities have been put into operation nationwide, with a total designed treatment capacity exceeding 50 billion m2 3 / d. An outstanding feature of the sewage treatment plant is that there are many types of pools and large areas: adjustment tanks, acid hydrolysis tanks, primary sedimentation tanks, aeration grit sedimentation tanks, biochemical tanks, secondary sedimentation tanks, high-density sedimentation tanks, sand filter tanks, UV Disinfection pool, etc. In the production process, due to the complex composition of pollutants, the interaction of metal ion...
