深度处理工艺应用于黄河源水的中试研究

Pilot Study on Advanced Treatment Process of Source Water from Yellow River

研究了北京市备用水源黄河水进京后对北京水厂现有工艺的适应性。通过比较黄河水源与北京本地密云水源的水质区别,发现黄河源水的氨氮和耗氧量较密云源水要高。针对这一水质特点,在郑州建立一套中试系统,模拟北京现有水厂工艺,考察该工艺对黄河水源的适应性。结果显示,深度处理工艺对氨氮和亚硝酸盐氮有良好的去除效果,炭池出水中两者浓度大幅下降。黄河源水中主要有机物有两类,分别是色氨酸类芳香族蛋白质和溶解性微生物代谢物,臭氧-活性炭工艺对色氨酸类芳香族蛋白质的去除率很高,且对溶解性微生物代谢物达到100%完全去除。

The adaptability of current drinking water treatment processes in Beijing to its emergen- cy water source （ from Yellow River） was investigated. Water from Yellow River and Miyun Reservoir was compared in terms of water quality, and the concentrations of ammonia nitrogen and COD in water from Yellow River were higher than those in water from Miyun Reservoir. In Zhengzhou a pilot system based on the current treatment processes in drinking water plants in Beijing was established to study their adaptability to water source from Yellow River. The results showed that ammonia nitrogen and nitrite nitrogen could be efficiently removed by advanced treatment processes. Moreover, O3/PAC treatment could significantly remove amino acid protein and soluble microbial metabolites, two dominating organics in water from Yellow River.
