Embodiment Construction

[0013] The present invention will be further described below in conjunction with embodiment.

[0014] An industrial sewage treatment agent, the mass parts of the industrial sewage treatment agent are as follows: 1.2-2.8 parts of polyacrylamide, 30-50 parts of alum, 4-6 parts of ferric chloride, 1.2-3 parts of polyferric sulfate , coagulation aid 1.2-2.5 parts, potassium persulfate 3-8 parts, starch 12-28 parts, urea 1.2-2.5 parts, hydrogen peroxide 5-10 parts, solvent-type lignin 5-20 parts, sodium phosphate-phosphoric acid Sodium dihydrogen buffer system 10-15 parts, bentonite 10-20 parts.

[0015] The polyacrylamide is selected from at least one of anionic polyacrylamide and nonionic polyacrylamide.

[0016] The coagulation aid is made of bamboo shoot skins, and the preparation method is as follows: put the bamboo shoot skins into 12% potassium hydroxide solvent, soak for 2 hours, then put the soaked bamboo shoot skins into the modification solution at 50°C, and simultaneou...

Abstract

The invention relates to the technical field of sewage treatment, particularly an industrial sewage treating agent. The industrial sewage treating agent is composed of the following components in parts by mass: 1.2-2.8 parts of polyacrylamide, 30-50 parts of alum, 4-6 parts of iron trichloride, 1.2-3 parts of polyferric sulfate, 1.2-2.5 parts of coagulant aid, 3-8 parts of potassium persulfate, 12-28 parts of starch, 1.2-2.5 parts of urea, 5-10 parts of hydrogen peroxide, 5-20 parts of solvent-type lignin, 10-15 parts of sodium phosphate-sodium dihydrogen phosphate buffer system and 10-20 parts of bentonite. The industrial sewage treating agent has the advantages of wide pollutant treatment range, favorable effect, wide production raw material sources, environment friendliness, no toxicity, good effluent water quality, short technical process and high technical operation safety. The treating agent can treat various types of sewage, such as chemical wastewater in oilfields, mines, iron and steel, electroplating, dyes, pesticides, wine making, chemical industry and the like, and domestic sewage, paper mill wastewater, rivers and lakes, garbage seep water, tanning wastewater and the like. The treating agent has favorable treatment effect.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an industrial sewage treatment agent. Background technique [0002] my country is a country with a shortage of water resources, how to alleviate the shortage of water resources and pollution has become an urgent problem. [0003] At present, the coagulants commonly used in sewage treatment agents mainly include inorganic flocculants and organic polymer flocculants. Inorganic flocculants are a new type of water treatment agents developed on the basis of traditional aluminum salt and iron salt flocculants. With more and more types and quantities of wastewater discharged from factories, and the water quality becoming more and more complex, pure aluminum and iron salt inorganic polymer flocculants can no longer meet the increasingly high requirements in the wastewater treatment process. Therefore, the research on polysilicate iron aluminum coagulant, polyaluminum iron silic...
