摘要：

Based on the turbidity, lower temperature and micro-pollution of cellar water in villages and towns in northwest China, removal efficiency of turbidity. Results showed that the turbidity in yielding water became stable and the average removal rate reached 92%, 20%, 32%, 32%, 22% respectively after operating integrate technology for 25 days. After cellar water was treated through rough filtration plus slow biological filtration technics, all indexes above accorded with the standards of drinking water quality. Thus, this integrate technology can be used to reprocess the diminutive and scattered cellar water of villages and towns in northwest China.
