Purifying agent for water purification equipment and preparation method thereof

Abstract

The invention provides a purifying agent for water purification equipment and a preparation method thereof. The purifying agent is prepared from the following components: attapulgite, zinc oxide, silicon oxide, alumina and nickel. The preparation method comprises the following steps: 1, drying attapulgite, grinding into particles, and respectively grinding the zinc oxide, silicon oxide, alumina and nickel into particles; 2, adding the particles in the step 1 into a stirrer, stirring for 30-50 minutes to obtain mixture 1, and adding water which is 30-40 percent of the weight of the mixture 1 for wetting to obtain mixture 2; 3, rolling the mixture 2 for 3-5 times with a roller, and controlling the thickness to be 1-3mm to obtain flakes; 4, roasting the flakes at 600-800 DEG C for 40-60 minutes to obtain a semi-finished product; and 5, grinding the semi-finished product in a grinder to obtain powder having a particle fineness of less than 50mu m, and packaging for molding. The purifying agent has relatively strong adsorbability, and can be used for effectively removing impurities in water; and the preparation process is simple, is easy to operate, and has low requirements for processing equipment.

Description

technical field [0001] The invention belongs to the technical field of purifying agents, and in particular relates to a purifying agent used in water purification equipment and a preparation method thereof. Background technique [0002] Aluminum and iron polymer inorganic polymer water purifiers are a new type of chemical industry researched and developed from the 1970s to the 1990s, which has played a great role in improving people's quality of life and improving the environment. There are many types of water purifiers, and the production processes are different. At present, the waste residue of the sulfuric acid plant is discharged randomly, causing environmental pollution, which urgently needs to be treated. Chinese patent CN1219507A discloses a "one-step production process of polymeric ferric sulfate solid water purifying agent", which uses iron oxide-containing waste residues from iron and steel plants and sulfuric acid plants to react with oxidants to produce iron-bas...

Problems solved by technology

This patent application is only in the stage of laboratory testing. In the embodiment, sulfuric acid should be added to the beaker containing iron oxide waste residue in stages, and the reaction temperature should be controlled at 40-70°C, which is difficult to grasp in actual production. In addition, the production process is not Adding oxidant, ferrous iron cannot be converted into ferric iron, and the polymerization effect cannot be achieved, and the substances in iron slag are impure, solid and liquid are not separated, and the water insoluble content is too high, which affects the water purification effect, and does not have industrial production
