Abstract

The invention belongs to the technical field of sewage and wastewater treatment agents, and discloses a composite water treatment agent as well as a preparation method and a use method thereof. According to the agent, the wide adsorption effect of activated carbon in the agent, the netting effect of long-chain colloid formed by polymeric ferric sulfate in a water body and colloid precipitation formed by the colloid and metal salt in the water body are utilized to precipitate suspended solids, organic matters and orthophosphate, and then precipitation of various pollutants is achieved. The sewage treatment agent has the effects of efficient adsorption and rapid flocculation, can rapidly decolor a water body, reduce COD, reduce the total phosphorus content and the like, and is simple to add and operate. The sewage treatment agent has the characteristics of environmental protection, high efficiency, small addition amount, no special requirements on dosing equipment, fast reaction, fast sedimentation, stable effluent, no secondary pollution and the like. The raw materials in the composite reagent are nontoxic and harmless. The treatment effect on total phosphorus in wastewater is higher than that of a Fenton reaction method; the color reversion phenomenon does not exist after chromaticity treatment, but the agent is simple to add and has low requirements on facilities.

Description

technical field [0001] The invention belongs to the technical field of sewage and wastewater treatment agents, and in particular relates to a compound water treatment agent and its preparation method and use method. Background technique [0002] Water is the most precious natural resource for human survival and development. As the shortage of water resources intensifies, water pollution has drawn more and more attention from all countries in the world. [0003] Countries all over the world have invested a lot of manpower and material resources in sewage treatment. The research on sewage treatment has become more and more in-depth, and the sewage treatment technology has been developed rapidly. Especially in the vast developing countries, the changes in sewage treatment technology are changing with each passing day in recent years. [0004] There are many methods of sewage treatment, which are divided into physical treatment, chemical treatment, biological treatment and compr...
