Abstract

The invention relates to a method for preparing a multi-copolymerization diacid water purifying agent from aluminum alloy sludge, which is characterized by comprising the following production steps of: preparing mother liquor A, mother liquor B, mother liquor C, basifier K, polyion mono-acid system M and a multiple diacid system N by treating the sludge; adding the multiple diacid system N, zinc chloride, magnesium chloride and the basifier K into a reaction kettle f; and rapidly stirring and regulating a Ph value to obtain the product, i.e. the multi-copolymerization diacid water purifying agent PAMZ. Intermediate products and final products in the treatment process of the multi-copolymerization diacid water purifying agent PAMZ obtained by copolymerization can be used as sewage treatment water purifying agents for treating the sewage. Due to the adoption of the method, the difficult problem of treating the aluminium alloy sludge is effectively solved, the considerable economic benefits are created and the pollution risk of heavy metal sludge on the environment is eliminated.

Description

technical field [0001] A method for preparing a multi-component copolymerized di-acid water purifier from aluminum alloy sludge. The multi-component copolymerized di-acid water purifier PAMZ is produced by utilizing the useful metals and removing the harmful heavy metals. It has an excellent effect in treating wastewater and belongs to Environmental technology field. Background technique [0002] Since a large amount of sludge is produced in the processing and production of aluminum alloys, the sludge contains utilizable components (aluminum, zinc, magnesium) and harmful components (heavy metals and other impurities), can it be dissolved and the useful components Make full use of it, adjust the content of various metals, separate harmful components, and make the products made of them have qualified and stable quality, which has become the key to the treatment and reuse of aluminum alloy sludge. In the existing technologies for treating this type of sludge, there is no techn...
