为提高传统净水工艺下的处理出水水质，通过对水厂原水的烧杯混凝试验，采用多种混凝剂，以及投加助凝剂，改变水力条件等，取得了进一步提高水质的操作条件。试验发现，增加投药量，有机物的去除率伴随浊度去除率的提高而提高。投放助凝剂可得同样效果，并可使药耗降低。pH值的降低有利于有机物的去除，但生产上不易实现。

To improve the water quality treated by conventional facilities, the operative p arameters to further improve the water quality are gained by the test on the sou rce water of a water plant. In the test, several kinds of coagulant and one coag ulant aids are added and hydraulic conditions are varied. The test results show that when increasing the coagulant dosage the removal ratio of organic carbon ge ts higher with the improving of the removal ratio of turbidity. The same effect and decreasing the dosage used may approach by using the coagulant aids. The dro pping of the pH is benefit for the removal of the organic substance, but it is hard to be applied.
