Abstract
The invention relates to a polyferric chloride water purifying agent and a preparation method. Iron is added into a waste hydrochloric acid solution for a reaction, and the waste hydrochloric acid solution reaching the certain 1.5-1.6 molar ratio of [H+]/[Fe2+] is added into a reaction kettle through a metering tank; under the normal temperature, 2-5% of sulfuric acid, 3-6% of sodium silicate and 0.1-0.6% of borax are added during stirring, and a reaction is performed for 25-35 min; and when it is detected that the specific gravity of ferrous ions is 1.3: 10, a mixed material is placed into a storage tank to be subjected to ageing for 24 h, and then the product is obtained. According to the polyferric chloride water purifying agent and the preparation method, waste hydrochloric acid is adopted as a raw material and is made to be capable of cyclically utilized again, because the sulfuric acid, the sodium silicate and the borax are added, the water purifying effect is good, various pollution components in water can be effectively treated, the adsorbing capacity is high, and no secondary pollution is generated.
