Abstract
Based on the turbidity, the lower temperature and micropollution of cellar water in villages and towns in Northwest China, and the removal efficiency of turbidity, CODMn, NH3 -N, UV254 was analyzed in this integrate technology by simulating Northwest cellar rainwater for raw water. Results showed that the turbidity, CODMn, NH3 -N, UV254 in yielding water became stable and the average removal rate reached 92%, 30%, 32%, 32% respectively after integrate technology was operating for 25 days. The above indexes after rough filtration plus slow biological filtration technics all accord with the standards of drinking water quality. So, this integrate technology can be used to retreat the diminutive and scattered cellar water of villages and towns in Northwest China.
