Problems solved by technology

[0004] The Chinese patent with the application number CN201310481165.0 discloses a flocculant for sewage treatment of animal husbandry farms. The organic matter and antibiotics have good flocculation and sedimentation effects. The flocculant itself can also be gradually decomposed without residual hazards, so that the water quality can reach the standard. The ingredients of the flocculant provided by the invention are easy to obtain and low in price, which reduces the cost of sewage treatment. The flocculant provided by the invention has limited flocculation ability and is not effective in removing heavy metal ions

Embodiment 1

[0028] A sewage treatment flocculant in parts by weight, comprising the following raw materials: 20 parts of 10-30 mesh zeolite powder, 50 parts of celery leaf powder, 6 parts of dendrobium leaf powder, 20 parts of carboxymethyl starch, 1 part of 8-hydroxyquinoline 7.5 parts of chitosan, 6 parts of modified dissolving pulp, 3 parts of tung oil anhydride, 3 parts of modified bio-oxidized oil.

[0029] The concentration of the modified dissolving pulp is 20%. The modified dissolving pulp is obtained by adding cellulase with a mass of 1% of the dissolving pulp to the dissolving pulp and hydrolyzing it at 40° C. for 30 hours. The dendrobium leaf powder is obtained after the production of Dendrobium candidum, the thicker leaves of the mesophyll in the residual discarded dendrobium leaves are crushed to 80 mesh, and 100g of the dendrobium leaf powder is soaked in 200mL of 0.2mol / L sodium hydroxide at 40 degrees Celsius, 0.1mol / L Add 0.2 mol / L hydrochloric acid to neutralize after 2...

Abstract

The invention discloses a sewage treatment flocculating agent and a production method thereof. The sewage treatment flocculating agent comprises 10-30-mesh zeolite powder, celery leaf powder, dendrobium leaf powder, carboxymethyl starch, 8-hydroxyquinoline, chitosan, modified dissolving pulp, tung oil anhydride and modified biological oxidized oil. The production method of the sewage treatment flocculating agent comprises the step of producing the sewage treatment flocculating agent through mixing and the like. According to the sewage treatment flocculating agent and the production method thereof, by adopting the modified dissolving pulp, the tung oil anhydride and the modified biological oxidized oil as a reinforcing system, the flocculation capability and the heavy metal ion removal rateof the sewage treatment flocculating agent are improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment flocculant and a preparation method thereof. Background technique [0002] Flocculation treatment of sewage is one of the most economical and practical methods at present. By adding a flocculant to the water body, the pollutants in the water form insoluble or insoluble substances that float on the water or sink to the bottom of the water, and finally achieve the purpose of removal. [0003] Livestock and poultry manure is not only a valuable organic fertilizer resource, but also a serious source of pollution. If it is discharged into the environment without proper treatment, it will cause serious pollution to surface water, groundwater, soil and air, and endanger the health of livestock and poultry itself and human beings. The content of pollutants in the sewage discharged from livestock and poultry farms is much higher than that of ordinary residents...
