Although a very comprehensive data analysis can be obtained through a laboratory through a periodic sampling detection mode, under the condition of relatively strong fluidity, pollutants are possibly washed away in sampling interval time, so that the pollution of rivers in the later period is difficult to find a source, and responsibility tracing is difficult to perform. In addition, for key water areas, such as water source areas or key lake pollution treatment areas, the pollution treatment areas are generally far away and have large areas. If the sampling period is too long, a great hidden danger obviously exists, particularly in a water source area, once the sampling period reaches below two times in a month, the water quality problem is found later, and thousands of drinkers are damaged healthily at this time.
