Abstract
The invention discloses a flocculant and preparation method thereof. The flocculant is prepared from the following formula components in parts by mass: 6 to 8 parts of polyvinylpyrrolidone, 2 to 6 parts of aluminium polychlorid, 1 to 2 parts of sodium carbonate, 7 to 9 parts of natural organic acid, 5 to 7 parts of sodium thiosulfate pentahydrate, 6 to 10 parts of polyacrylamide, 6 to 7 parts of calcium aluminate, 3 to 7 parts of chlorine dioxide, 4 to 6 parts of aluminum ammonium sulfate, 6 to 10 parts of sodium hypochlorite, 5 to 9 parts of sodium carbonate, 6 to 8 parts of calcium disodium versenate and 1 to 3 parts of lubricant. The flocculant provided by the invention has the advantages that the flocculating efficiency is high, the effect is good, the flocculant is specially suitable for dyeing wastewater treatment, the decolorization rate is over 90 percent, and the removal rate of CODcr is more than 78 percent.
Description
Technical field [0001] The invention relates to the field of sewage treatment, in particular to a flocculant and a preparation method thereof. Background technique [0002] In the sewage treatment process, flocculants are often used to quickly condense the harmful components in the sewage to form a precipitate, and then filter to achieve the purpose of water purification. There are various flocculants in the prior art, but they generally have problems of low coagulation efficiency and unsatisfactory effects. [0003] Therefore, the existing technology needs to be improved. Summary of the invention [0004] The invention provides a flocculant and a preparation method thereof. The flocculant of the invention has high coagulation efficiency and good effect, and is particularly suitable for treating printing and dyeing wastewater, with a decolorization rate of more than 90% and a CODcr removal rate of more than 78%. [0005] In order to achieve the above objectives, the present inventio...
