Abstract

The invention discloses a high-efficiency flocculant which is composed of the following components in parts by weight: 15-25 parts of polyaluminum silicate sulfate-aluminum potassium sulfate mixture, 5-10 parts of ferric citrate, 3-5 parts of potassium ferrate, 2-5 parts of polyferric chloride phosphate, 5-10 parts of polyferric phosphate, 5-10 parts of polyaluminum chloride, 10-15 parts of soluble coating and 3-5 parts of flocculant activating component. The flocculant activating component is selected from one or combination of expanded perlite micropowder and fly ash micropowder, wherein the weight ratio of the expanded perlite micropowder to the fly ash micropowder is 3:2-5:3. The flocculant disclosed by the invention has the advantages of wide raw material sources, low production cost, low material input, favorable flocculation activating effect and low flocculation processing cost.

Description

[0001] technical field [0002] The invention discloses a water treatment additive, in particular a high-efficiency flocculant. Background technique [0003] The flocculant is mainly a group with positive (negative) charge and some particles or particles with negative (positive) charge in some water that are difficult to separate, reduce its potential, make it in an unstable state, and use its The aggregated nature allows these particles to be concentrated and separated by physical or chemical means. The agents generally used for this purpose are called flocculants. Flocculants are mainly used in the fields of water supply and sewage treatment. Coagulation and sedimentation of chemical agents is a commonly used method in water treatment technology. The method has the characteristics of low investment, small land occupation, low operating cost and wide adaptability. In water treatment coagulation and sedimentation, the timing of flocculant feeding, feeding environment...
