Abstract

The invention discloses a treatment agent for chlorine-containing wastewater. The raw materials include waste hydrochloric acid solution, nanometer calcium, nanometer aluminum oxide, demineralized water, sodium dodecylsulfonate, stabilizer and adsorbent. The present invention also proposes a preparation method of a chlorine-containing wastewater treatment agent, which includes the following steps: after uniformly mixing nano-calcium and nano-alumina, calcining to obtain prefabricated material A; adding prefabricated material A and sodium dodecylsulfonate After being stirred and reacted in the waste hydrochloric acid solution, the prefabricated material B is prepared by standing; the desalted water, adsorbent, and stabilizer are added to the prefabricated material B, mixed evenly, shaken and dried to prepare the chlorine-containing waste treatment agent. The chlorine wastewater treatment agent of the invention has high chlorine removal efficiency, good removal ability for pollutants such as heavy metals and phosphorus, simple preparation process, low cost and wide market prospect.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a chlorine-containing wastewater treatment agent and a preparation method thereof. Background technique [0002] There are two types of sources of chloride in surface water: natural sources and anthropogenic sources. Natural sources include water flowing through chloride-containing formations, causing salt deposits and other chloride-containing deposits to dissolve in water and rivers or rivers close to the ocean that are blown by tides and seawater. The impact of incoming winds leads to an increase in chloride content in water; man-made sources mainly include mining, petrochemical, food, metallurgy, leather (tanning), chemical pharmaceuticals, papermaking, textiles, paints, pigments, and machinery manufacturing industries. Industrial wastewater and domestic sewage generated by human life, of which industrial discharge is the main source. [0003] The chloride content in...
