Abstract

The invention provides a water purifying agent composition and application thereof. The water purifying agent composition is mainly prepared from the following components by weight percent, which are 100 percent of the weight of the water purifying agent: 5 to 10 percent of chitosan, 20 to 30 percent of polymeric ferric sulfate, 10 to 20 percent of iron chloride, 40 to 50 percent of active carbon and 10 to 20 percent of aluminum sulfate. When the water purifying agent composition is applied to the waste water treatment, when the feeding amount is 200mg / L, the removal rate for the turbidity of waste water can reach up to 95 percent or more, the total phosphorus removal rate can reach up to 90 percent or more, the COD removal rate can reach up to 35 percent or more, and the BOD removal rate is 80 percent or more; and moreover, the water purifying agent composition is rich in source of raw materials, low in cost and good in market application prospect.

Description

technical field [0001] The invention belongs to the field of water treatment, and relates to a water purifying agent composition and an application thereof. Background technique [0002] Water is the source of life, water pollution and shortage of water resources force people to pay more attention to the protection of water resources and the treatment of wastewater. How to make wastewater meet the national discharge standards is an urgent problem to be solved. [0003] At present, in the wastewater treatment process, flocculants are often used to treat wastewater. The traditional four-stage coagulation-sedimentation-filtration-disinfection water treatment process can no longer cope with the current water pollution problems. Therefore, it is necessary to develop a coagulation A water purifying agent with dual functions of adsorption and adsorption, so as to carry out advanced treatment of water pollution. [0004] CN 101979328A discloses a chitosan composite gel water purif...
