The relationship between the removal rate of effluent treated with anionic polyacrylamide and the settling velocity
The use of polyacrylamide in the treatment of various industrial wastewater, the removal of impurities in water is a very important indicator, is to determine the processing results of the important factors. Xiaobian today to explain: anionic polyacrylamide treatment of sewage removal rate and the relationship between the settlement speed.
Anionic polyacrylamide dissolved in the course of the use of the first chemical reaction occurs in the reaction of insoluble in the solution of the solution of the material, that is, under the action of gravity can be quickly settled, suspended solids in the sewage is important to sewage treatment One of the technical, technical staff found that: according to the nature of suspended matter, precipitation can be divided into natural set, flocculation sedimentation, regional precipitation, the use of anionic polyacrylamide products for flocculation settlement can be clearly seen with clarified water There is a clear interface for muddy water separation!
Anionic polyacrylamide products in the flocculation settlement, the suspended solids and colloidal particles in the product of the molecular force of mutual assistance under the action of a floc in the settlement process of anionic polyacrylamide products produced by the floc collide with each other , The quality and size of the floc at this time are constantly changing, the speed of sedimentation is also increasing, so the removal rate of suspended solids depends not only on the settling rate of amide, with the depth of precipitation has a relationship!
