Embodiment 1

[0022] The composition of the sewage flocculant: 6 parts of polyacrylamide, 2 parts of citric acid, 4 parts of composite microorganisms, 2 parts of polyferric chloride, 5 parts of bentonite and 0.3 parts of microbial accelerator hesperidin. Composite microorganisms are powders of mixed strains, including bacillus licheniformis, actinomycetes and rhizobacteria. The content of each strain in the composite microorganism is 1×10 7 cells / gram.

[0023] When in use, add 0.7kg of the above-mentioned sewage flocculant per 100kg of sewage.

Embodiment 2

[0025] The composition of the sewage flocculant: 5 parts of polyacrylamide, 1 part of citric acid, 3 parts of compound microorganism, 1 part of polyferric chloride, 4 parts of bentonite and 0.2 part of microbial accelerator hesperidin. Composite microorganisms are powders of mixed strains, including bacillus licheniformis, actinomycetes and rhizobacteria. The content of each strain in the composite microorganism is 1×10 5 cells / gram.

[0026] When in use, add 0.5kg of the above-mentioned sewage flocculant per 100kg of sewage.

Embodiment 3

[0028] The composition of the sewage flocculant: 7 parts of polyacrylamide, 3 parts of citric acid, 5 parts of composite microorganisms, 3 parts of polyferric chloride, 6 parts of bentonite and 0.4 parts of microbial accelerator hesperidin. Composite microorganisms are powders of mixed strains, including bacillus licheniformis, actinomycetes and rhizobacteria. The content of each strain in the composite microorganism is 1×10 9 cells / gram.

[0029] When in use, add 1kg of the above-mentioned sewage flocculant per 100kg of sewage.

Abstract

The present invention discloses a sewage flocculant, which comprises, by weight, 5-7 parts of polyacrylamide, 1-3 parts of citric acid, 3-5 parts of a composite microorganism, 1-3 parts of polymerization ferric chloride, 4-6 parts of bentonite, and 0.2-0.4 part of a microorganism accelerator hesperidin. According to the present invention, the sewage flocculant has effects of good flocculation effect, effective removal of organic matters and heavy metal ions in water, sewage turbidity reducing, and sewage treatment efficiency improving; the composite microorganism provides important effects in the fields of organic matter removal and heavy metal ion removal, and the added accelerator hesperidin can significantly improve the removal ability of the composite microorganism on organic matters and heavy metal ions; and with the matching of the sewage flocculant and the existing sewage treatment system, the sewage treatment effect achieves the national emission standard, and the ecological and efficient urban industrial and domestic sewage treatment is achieved.

Description

technical field [0001] The invention relates to sewage treatment, in particular to a sewage flocculant. Background technique [0002] A flocculant is a coagulant that can make the sol into a flocculent precipitate. The flocculant can separate the dispersed phase from the dispersion medium to separate the flocculent precipitate, and its coagulation is called flocculation. Common flocculants used to promote the sedimentation, filtration and clarification of waste in waste liquid, including inorganic substances and organic polymers, are used to promote the settlement, filtration and clarification of waste in waste liquid. The two can be used alone or in combination, but the combination is more effective than the use alone. [0003] The flocculation process mainly includes 4 stages: [0004] ①Add flocculant to wastewater; [0005] ② The flocculant diffuses in the liquid; [0006] ③Stir to make the flocculant and suspended particles contact; [0007] ④ Stirring to make the ...
