Abstract

The invention discloses a preparation method of a sewage treatment flocculant. The preparation method comprises the following steps: (1) preparing an aqueous solution of chitosan acetic acid and iridium chloride, stirring, adding an ethanol solution of span-80 and polyethylene glycol into the solution, carrying out water bath treatment at constant temperature, and adding glutaraldehyde; (2) adjusting the pH value to 9-10, carrying out solid-liquid separation, and washing and drying the obtained solid phase; (3) preparing a black brin-kiwi fruit extract, adjusting the pH value to 13-14, addingthe solid phase prepared in step (2), heating in a nitrogen atmosphere, cooling, filtering, washing and drying to obtain a solid phase B; (4) adding the solid phase B and aluminum phosphate into 2,3-dihydropyran, keeping the temperature constant, carrying out solid-liquid separation, and washing and drying to obtain a solid phase C; (5) sequentially soaking the solid phase C in an aqueous solutionof hydrogen peroxide and sodium acrylate, and adding epoxy chloropropane to obtain a solid phase D; and (6) performing acid soaking, filtering, washing and drying on the solid phase D to obtain the sewage treatment flocculant. The flocculant prepared in the invention has an obvious sewage treatment effect and stable performance.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a sewage treatment flocculant and a preparation method thereof. Background technique [0002] In order to effectively alleviate the impact of water pollution on people's lives and social and economic development, researchers around the world are trying to solve various freshwater pollution problems, and effectively solve polluted water resources through advanced water treatment methods and technologies The regeneration of water resources and the reuse of water resources have become the key to the sewage treatment and water resources regeneration in our country. Water resource regeneration is mainly through the advanced treatment of polluted water to convert polluted water into usable fresh water resources. At present, there are many methods and means of wastewater treatment, mainly including adsorption method, ion exchange method, imbibition method, floccula...
