ABSTRACT
The water body of the Y River in China is seriously black and odorous. The Water Affairs Bureau of Z District has set up a water purification station to treat the Y River. The water purification station adopts the “coarse grid + fine grid + magnetic microfiltration treatment + two-stage aeration biological filter” process. The effect of this process is stable, and the effluent can reach the quasi-IV class water standard. The correlation analysis of the water quality parameters of the influent water shows that the pH of the influent water is correlated with COD, NH4+-N and other parameters. The influent water quality can be predicted by detecting pH, which provides parameters for the process debugging of the water purification station
