Abstract

The invention discloses an efficient composite high molecule flocculant. The flocculant is prepared from polyacrylamide, polysilicic acid, polymerization aluminium oxide, polyester rubber powder, a microbial agent, natural clay, sodium starch octenyl succinate, microcrystalline cellulose, polyvinyl pyrrolidone, calcium peroxide, potassium permanganate, a silane coupling agent and a titanate coupling agent. A preparation method of the flocculant comprises the steps that (1) the natural clay is subjected to high-temperature activation and soaked in the microbial agent, and through compounding, acomposite microorganism material is obtained; (2) under the effect of the silane coupling agent, the polymerization aluminium oxide, polyacrylamide and polysilicic acid are compounded to prepare a composite material; (3) the composite microorganism material, the composite material and the remaining raw materials are evenly mixed to obtain the composite high molecule flocculant. The prepared composite high molecule flocculant is high in stability, capable of achieving quick sedimentation and high in treatment efficiency.

Description

technical field [0001] The invention belongs to the technical field of flocculants, and in particular relates to a high-efficiency composite polymer flocculant and a preparation method thereof. Background technique [0002] Water is the source of life, and water pollution is the most important aspect of environmental pollution, which will directly or indirectly lead to the death of people and other living things. At present, water pollution is very serious and has become one of the major problems faced by countries all over the world. With the increase of population and the continuous development of industry, we use more water resources, but due to climate change and environmental damage, our country can use less and less water resources, if no measures are taken, our country will face more serious problems This will bring a very unfavorable situation to the development of our country's society and economy and people's lives. [0003] The total amount of sewage discharged ...
