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.

Abstract

The invention discloses an industrial wastewater treating agent. The industrial wastewater treating agent is mainly prepared from raw materials in parts by weight as follows: 15-30 parts of polymeric silicate-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 zinc sulfate, 4-11 parts of diatomite, 20-40 parts of modified lava stone, 10-20 parts of calcium hydroxide, 10-20 parts of activated carbon, 5-15 parts of polymeric aluminium, 1-5 parts of menthone and 5-20 parts of lignin. The industrial wastewater treating agent is prepared from widely sourced raw materials, can effectively remove pollutants in water, treats sewage thoroughly, and is low in treatment cost, non-toxic and pollution-free, and treated wastewater meets the requirements of national integrated wastewater discharge standard. Besides, the preparation method is simple, and production is facilitated.

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...
