Industrial waste water treatment agent and preparation method therefor

Abstract

The invention discloses an industrial waste water treatment agent. The industrial waste water treatment agent is mainly prepared from the following raw materials in parts by weight: 15-30 parts of aluminum sulfate, 15-30 parts of ferric sulfate, 1-5 parts of polyacrylamide, 1-5 parts of microorganisms, 15-30 parts of corn starch, 3-13 parts of chitosan, 7-17 parts of bentonite, 5-10 parts of sodium cellulose, 4-11 parts of montmorillonite powder, 20-40 parts of modified pelelith, 10-20 parts of calcium hydroxide, 10-20 parts of activated carbon, 5-15 parts of polymeric aluminum, 1-5 parts of aluminum ammonium sulfate, 3-7 parts of 3-chloro-2-hydroxypropyl-trimethylammonium chloride, 5-15 parts of barium sulfide and 5-20 parts of lignin. The manufacturing raw materials of the industrial waste water treatment agent are wide in source, pollutants in the waste water can be effectively removed, the sewage treatment is thorough, the treatment cost is low, and the treatment agent is non-toxic and pollution-free; the treated waste water satisfies the requirements of national sewage comprehensive discharge standard. Moreover, the preparation method of the industrial waste water treatment agent is simple and the industrial waste water treatment agent is convenient to produce.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to an industrial wastewater treatment agent and a preparation method thereof. Background technique [0002] Wastewater refers to the general term for water discharged during residents' activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other useless water such as primary rainwater that flows into drainage pipes and canals. It generally refers to water that cannot be recycled after certain technical treatment or that is difficult to purify after primary pollution and cannot meet a certain standard. With the rapid development of my country's chemical industry, various new chemical products are applied to all walks of life, especially in heavy polluting industries such as medicine, chemical industry, electroplating, printing and dyeing. Industrial wastewater flows directly into channels, and rivers and lakes pollute surface water. If it is high...

Problems solved by technology

Due to the various and mixed types of water pollutants, and the main water treatment agents currently used have a single function, it is necessary to add flocculants, corrosion inhibitors, fungicides and other agents to the water treatment system, and the treatment process is complicated.

There are a lot of equipment, complicated operation process, large amount of dosage and high cost, and various reagents will resist each other through various chemical reactions, resulting in a decrease in drug efficacy.

However, the existing water treatment agents often have weak adsorption capacity for some heavy metal ions.
