- Abstract:
- Pipeline direct drinking water (pipeline purified water) is currently the most economical and effective method to improve the drinking water health of urban residents in China. A comprehensive pipeline direct drinking water production and distribution system was constructed throughout the entire campus of a domestic university, so as to ensure the health and safety of drinking water for teachers and students staff. The scale of the direct-drinking water system is 60 m3/d, and the main water purification process consists of nanofiltration, micro-electrolysis and UV sterilization. The total investment of the project is approximately 4.8 million yuan, and the direct cost is 15 yuan/m3. The turbidity in effluent is less than 0.05 NTU, the CODMn in effluent is less than 0.5 mg/L, the trichloromethane in effluent is less than 0.01 mg/L, and the total dissolved solids (TDS) is approximately 50 mg/L, indicating that all indicators are better than the limit specified in Water Quality Standards for Fine Drinking Water (CJ 94-2005).
