Composite water treatment agent and preparation method thereof

Abstract

The invention discloses a composite water treatment agent and a preparation method thereof. The composite water treatment agent comprises the following raw materials in parts by weight: 20-40 parts of aluminizing zinc slag, 15-25 parts of coal ash, 10-20 parts of plant fibers, 5-10 parts of sulfuric acid, 30-50 parts of sodium hydroxide, 2-4 parts of barium sulfide, 3-5 parts of iron sulfate, 4-6 parts of poly-silicon aluminum sulfate, 5-10 parts of maleic anhydride, 3-5 parts of 2-acrylamide-2-methylpropane sulfonic acid powder, 2-4 parts of sodium tungstate and 20-40 parts of hydrogen peroxide. The composite water treatment agent disclosed by the invention has a very good corrosion and scale inhibition effect, is wide in range of application, is high in universality, and has good effects in treating industrial wastewater of metallurgy, heavy metals, mines, printing and dyeing, spinning, building, casting, chemistry, power, leather, paper-making and the like as well as urban comprehensive sewage, is good in purifying quality, and is low in treatment cost; and after the composite water treatment agent is added into the sewage, coagulation reaction is quick, floc strength is high, precipitation is quick, clarifying and layering are easy, and efficiency is high.

AI Technical Summary

Benefits of technology

This technology can be used effectively with various industries' effluents like metal-processing or manufacturing processes that produce harmful materials during their production process. It works well even at different stages but it needs to have some type of agents added beforehand to prevent scaling on equipment parts due to acidic conditions caused by these reactions. By doing this, cleaned waters from all types of wastes will become more effective than untreatable ones without any treatments.

Problems solved by technology

This technical issue addressed in this patents relates to the development of efficient methods for treatments against harmful materials like metal scales (metal) without causing severe damages to sensitive components inside the process units' facilities due to their presence during operation. Existing techniques involve either applying acid solutions alone or combining different types of acids based on specific needs. However these conventional ways may be limited because they often result in significant amounts of residual organics entering the facility' s waters through effluence onto surrounding areas.
