采用杨树浦水厂新建的组合工艺(预臭氧氧化→高密度澄清池→砂滤→后臭氧氧化→生物活性炭)处理有机物和氨氮含量较高的黄浦江原水,研究水力负荷对该工艺处理黄浦江原水效果的影响,并分析该工艺在最佳水力负荷下长期运行时处理效果的变化情况.结果表明:该工艺能够长期稳定运行,出水水质达到国家饮用水标准,适宜作为微污染水源水的有效处理工艺;在设计水力负荷范围内,适当增加处理水量可更好地发挥该工艺的效用,且对有机污染物的去除率不会有明显降低;杨树浦水厂调试运转中该工艺流程的最佳水力负荷定为1 200m3/h.
The new combination process (pre-ozone oxidation → high-density clarifier → sand filtration → post-ozonation → bio-activated carbon) was used to treat Huangpu River raw water with high ammonia nitrogen content and the new combination process of Yangshupu Water Treatment Plant. The results show that the process can be operated stably for a long time and the effluent quality meets the national drinking water standard and is suitable for the effective treatment of micro-polluted source water Process; in the design of the hydraulic load range, the appropriate increase in the amount of water treatment can better play the role of the process, and the removal of organic pollutants will not be significantly reduced; Yangshupu water plant commissioning operation of the process of optimal hydraulic The load is set at 1 200m3 / h.
