Problems solved by technology

[0006] However, most of the current preparation processes simply consider the physical effects of minerals in the water treatment process, and mainly rely on the adsorption on the surface of mineral particles in the entire decontamination reaction, ignoring the chemical effects and synergistic effects of mineral components in water treatment. , so the product’s removal of pollutants is limited
In addition, the waste water produced by the original preparation process will cause secondary pollution to the environment, which cannot really achieve the purpose of environmental protection

Abstract

The invention discloses a treating agent for sodium bentonite mineral complex water, which comprises: sodium bentonite, ferric sulfate, aluminium sulphate and magnesium sulphate. This product has obvious dirt-removal effect for COD and heavy metal, and can be used in wide range, such as paper-making, dyeing and electroplating sewage.

Description

technical field [0001] The invention belongs to the field of environmental protection and relates to a water treatment agent. More specifically, the invention relates to a sodium-bentonite mineral composite water treatment agent and its preparation and application. Background technique [0002] Bentonite, also known as bentonite, bentonite, etc., is a clay rock-montmorillonite clay rock with montmorillonite as the main component. The target mineral of bentonite is montmorillonite (Montmorillonite), also known as microcrystalline kaolinite or kaolinite, which is a hydrous aluminosilicate mineral containing a small amount of alkali and alkaline earth metals. Its general chemical formula is: [0003] Na x (H 2 O) 4 {(Al 2-x Mg x )[Si 4 o 10 ](OH) 2} [0004] Bentonite is one of the main non-metallic minerals in my country, with reserves reaching 2.46 billion tons. It is widely used in chemical industry, casting, metallurgy and other fields. It has also been valued an...
