| 摘 要： | 研究不同无机絮凝剂对餐饮污水的处理效果,发现Al/Si摩尔比为3∶1的聚硅硫酸铝(PASS)对餐饮废水处理效果较好,确定其最佳操作条件,包括pH值,加药量,搅拌速度及沉降时间。再将最佳絮凝剂与PAM复配,确定最佳复配条件,以期提高COD的去除率。同时通过微电泳仪,倒置显微镜等现代分析仪器对废水和絮凝剂电性特征、絮体的形状进行对比研究,从电中和和吸附桥联角度初步探讨絮凝机理。

| Abstract: | Preparation of the composite flocculant refers to an inorganic coagulant PASS with Al/Si molar ratio 3∶1 mixed with PAM. Experiment concerning flocculation/sedimentation of restaurant wastewater samples includes jar tests and investigations with the instruments such as micro-electrophoresis for ζ potential measurement, and an invert microscope for observing floc. |
