Abstract

The invention discloses a composite water treatment agent used for treating industrial waste acid. The composite water treatment agent used for treating the industrial waste acid comprises the components: carbide slag, shell powder, plant ash, polyacrylamide, lauryl betaine, a quaternary ammonium salt, a coupling agent, sodium lignin sulfonate, sodium stearate and polyethylene wax. A production method of the composite water treatment agent used for treating the industrial waste acid comprises the following steps of (1) producing modified plant ash, wherein after a sodium hydroxide solution isadopted for conducting alkaline treatment and purification on plant ash, an obtained mixture and the coupling agent are stirred evenly to produce the modified plant ash; (2) conducting pre-treatment on a mixture, wherein high-temperature calcining is conducted on the carbide slag and the shell powder, then an obtained mixture, the sodium stearate, the polyethylene wax and the coupling agent are stirred and mixed to produce a pre-treated mixture; and (3) producing the composite water treatment agent, wherein the produced modified plant ash, the produced pre-treated mixture, the polyacrylamide,the quaternary ammonium salt, the lauryl betaine and the sodium lignin sulfonate are dried after being subjected to a stirring reaction, and grinding is conducted to obtain the composite water treatment agent.

Description

technical field [0001] The invention belongs to the technical field of industrial waste acid treatment, and in particular relates to a composite water treatment agent for industrial waste acid treatment and a preparation method thereof. Background technique [0002] In the chemical industry, it is usually necessary to use acids as reaction raw materials, media or catalysts. After the reaction and washing treatment, a lot of industrial waste acid is usually produced. Such as sulfuric acid titanium dioxide, waste sulfuric acid and waste electrolyte produced by hydrometallurgy (electrolysis) industries; waste hydrochloric acid in titanium tetrachloride, titanium dioxide chloride, sponge titanium and chlor-alkali industries; electroplating, Waste sulfuric acid, waste sulfuric acid / hydrochloric acid mixed acid, waste hydrochloric acid / waste nitric acid mixed acid produced in the pickling process; waste phosphoric acid produced in the phosphorus chemical industry, etc. These indu...
