无机高分子絮凝剂对餐饮污水的处理研究

Treatment of restaurant wastewater by inorganic polymer flocculant

采用不同无机高分子絮凝剂对餐饮污水进行处理,发现聚硅硫酸铝(PASS)的絮凝效果较佳。通过试验确定其最佳操作条件,并通过PASS和废水ζ电位的测定及PASS的形貌及处理废水后形成的絮体形态,从电中和以及吸附桥联角度初步探讨絮凝机理。

Treatment of restaurant wastewater is studied by using different inorganic flocculants, and PASS is found to have the best treatment effect. By means of jars test, the best operational conditions are determined, and the zeta potential of PASS and wasterwater are measured with microelectrophoresis. The images of PASS with different ratios and flocs are investigated by an inverted microscope, and the coagulation mechanism is discussed from the perspective of electro-neutralization and adsorption connection.
