摘要:
针对陡河水库微污染水源，分析了臭氧活性炭-超滤膜双深度处理核心工艺的净水效能、组合工艺效果及运行成本。结果表明，臭氧活性炭-超滤膜核心工艺适合处理微污染水库水，超滤膜出水浊度在0.03 NTU以下，高锰酸盐指数达到地表水Ⅰ类。其中，使用次氯酸钠对超滤膜进行维护性清洗（周期约为16 d），跨膜压差通过维护性清洗即可稳定在4~12 kPa，说明炭滤布置在超滤膜前的组合工艺运行效果稳定，超滤膜可截留活性炭以保证出水水质。炭滤布置在超滤前活性炭消耗较快，可通过活性炭碘值的变化来调整。分析该工艺和短流程超滤膜工艺的运行成本发现，次氯酸钠单耗分别为2.5、4.9 mg/L，制水单耗分别为0.18、0.19 kW·h/m3，该工艺药耗和制水电耗较低，长期运行性价比较高。
Abstract:
An analysis was conducted on the purification efficiency, integrated process performance, and operating costs of the core process involving ozone-activated carbon coupled with ultrafiltration membrane for treating the micro-polluted source water from Douhe Reservoir. The core process of ozone-activated carbon coupled with ultrafiltration membrane technology was suitable for the treatment of micro-polluted reservoir water. The ultrafiltration membrane effluent exhibited a turbidity of less than 0.03 NTU, and the permanganate index met the class Ⅰ limit for surface water quality specified in the standard. Sodium hypochlorite was employed for periodic maintenance cleaning of the ultrafiltration membrane, conducted approximately every 16 days, which effectively stabilized the transmembrane pressure difference within the range of 4 kPa to 12 kPa. This outcome demonstrated that the integrated process, featuring a granular activated carbon filter positioned upstream of the ultrafiltration membrane, operated with high stability. Furthermore, the ultrafiltration membrane effectively retained residual activated carbon particles, thereby ensuring consistent effluent quality. When the carbon filter was placed before the ultrafiltration membrane, the activated carbon consumption was rapid and could be replenished based on changes in its iodine value. The analysis of the operating costs between the present process and the short-process ultrafiltration membrane process indicated that the unit sodium hypochlorite consumption was 2.5 mg/L and 4.9 mg/L, respectively, while the specific energy consumption for water production was 0.18 kW·h/m3 and 0.19 kW·h/m3, respectively. The present process exhibited lower chemical usage and reduced energy consumption, demonstrating superior long-term operational cost-effectiveness.
