Abstract

Relating to the technical field of water purifying agents, the invention discloses a polyaluminum chloride water purifying agent containing a rare earth element and a preparation method thereof. The polyaluminum chloride water purifying agent containing a rare earth element comprises the following components by weight: 80-100 parts of an aluminum chloride block, 30-65 parts of bauxite, 10-25 partsof hydrochloric acid, 10-25 parts of sodium hydroxide, 10-25 parts of erbium soil and 5-15 parts of calcium chloride. The added rare element erbium can enhance the ductility of alum in water, thus enhancing the turbidity removal rate of wastewater and reducing the consumption of alkali in water, and part of calcium chloride can better stimulate erbium to play a more obvious role. In general, therare element Erbium can improve the turbidity removal rate of wastewater and reduce the alkali consumption in water, and calcium chloride can further improve the effect of erbium element in the polyaluminum chloride water purifying agent.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a polyaluminum chloride water purifier containing rare earth elements 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. Polyaluminum chloride is a water purification material, inorganic polymer coagulant, also referred to as polyaluminum, English abbreviation is PAC, the molecular weight produced due to the bridging effect of hydroxide ions and the polymerization of polyvalent anions Larger, higher charge inorganic polymer water treatment agent. It can be divided into solid and liquid in form. The solid can be divided into brow...
