| 摘 要： | 本研究采用混凝、超滤联用处理工艺对某厂生活污水站出水进行试验。试验结果表明，投加混凝剂会大大降低膜过滤阻力。混凝剂投加量为11mg／L时，具有良好的沉降性能，膜过滤阻力最小，去除浊度、CODcr、UV254效果最佳。

CHARACTERISTICS OF RESISTANCE IN FILTERING DOMESTIC WASTEWATER BY COAGULATION-UF PROCESS |
| |
| Abstract: | The influent water from a plant's domestic sewage station was tested by a combining coaglation-ultrafilter. The results showed that dosing coagulant would greatly lower the resistance of membarane filtering;when the dosing quantity of coagulant was 11mg/L, the resistance of membrane filtering was the smallest;the effects of turbidity, CODcr, UV252 removals were the optimium, possessing better sedmenting performance. |
