某净水工程位于黄河兰州段下游,原水不仅浊度高,且受兰州市排出的石油、化工等工业废水污染,其有害成分大大超过国家规定的标准(原水水质资料略),用常规的净化方法水质达不到国家规定的饮用水水质卫生标准。经试验研究采用了如图1所示的处理工艺流程,通过实际生产运行,取得理想的处理效果。现简介如下:
A clean water project is located in the lower reaches of the Lanzhou section of the Yellow River. The raw water is not only highly turbid, but is also polluted by industrial wastewater discharged from Lanzhou City, such as petroleum and chemical industries. The harmful components of the water purification project greatly exceed the national standards (the raw water quality data is omitted), and conventional purification is used. Methods Water quality does not meet national drinking water quality standards. The experimental study adopted the process flow shown in Figure 1, through the actual production and operation, to achieve the desired treatment effect. The brief introduction is as follows:
