Xintai Group: the application of polymeric aluminum chloride scenario

XINTAI Group Xiaobian tells you that the industrial paper wastewater discharge is very large, the black liquor produced by the paper industry will be mixed with the middle section of water after pretreatment, thus increasing the harmful substances in the paper wastewater, polymeric aluminum chloride used in the middle section of paper water treatment, COD and SS removal rate will also increase with the increase in alkalinity, but when the alkalinity reaches 75%, the removal rate will not increase but will decrease, when the temperature When the temperature is 250 and the salt content of polymeric aluminum chloride is 75%, the effluent can reach the national discharge standard. When paper wastewater is treated with polymeric aluminum chloride, the price of polymeric aluminum chloride is low, and the precipitate formed can be returned to the paper making process as raw material, which does not cause secondary pollution and can also produce actual economic benefits. Aluminum chloride, the removal rate of suspended matter can reach more than 95%, CODCr removal rate can reach 20-50%.

Xintai Group Xiaobian tells you that polymeric aluminum chloride can treat wastewater generated from daily life water and washing wastewater, oil stains, dust particles, etc., react with a large number of surfactants in water, thus forming negatively charged colloidal particles, which are easy to be fixed in water. Adding the right amount of polymeric aluminum chloride in wastewater will produce positive cations and multinuclear highly charged coordination ions, so that the charge suspended on the surface of colloidal particles has The adsorption and neutralization ability and the ability to compress the double electric layer, so that the colloidal particles destabilized adsorption precipitation and separation of water bodies.

Printing and dyeing wastewater contains a large amount of COD, PH value and chromaticity, although the coagulation effect of polymeric aluminum chloride in the use of good, low dosage, but the polymeric aluminum chloride to high alkalinity printing and dyeing wastewater neutralization ability is poor, its application will be limited, the use of two coagulant advantages of complementary and synergistic effect of the same ion, treatment of printing and dyeing wastewater can not only reduce treatment costs, but also improve the treatment effect.

Xintai Group Xiaobian tells you that oil-containing wastewater treatment oil-containing wastewater refers to the oil-containing wastewater produced by oilfield mining, oil refineries and petrochemical plants, which can be treated by oil separation and sedimentation, air floatation, biochemical and other methods. modified cationic polyacrylamide and polymeric aluminum chloride are used together, and the treatment effect is especially obvious. the relative molecular weight of modified cationic polyacrylamide should not be too high, and it is easy to be compounded with polymeric aluminum chloride in order to achieve ideal effect.

The above is the Xintai Group Xiaobian explained the "application of polymeric aluminum chloride scene" of the content, we all understand? I hope that the content of my explanation can help you, if you want to know more related knowledge, welcome to contact us Xintai Group, thank you for watching.
