The Study on the Wastewater Sampling Location of Water Pollution Source Monitoring
Abstract: Wastewater samples are a key link in the process of contaminants determination, and only the sampling process gets a representative sample, can the data be valuable. Therefore, sampling location has significant effect on sampling representative. This paper researches the spatial distribution of typical pollutants in wastewater in different flow states with the relative error method, in order to study the effect of sampling location for sampling representativeness. The results show that the pollutant distribution in laminar state is more heterogeneous than in turbulent state, and there will be more error in laminar flow condition; besides, multipoint samples need to be mixed for obtaining representative samples in the laminar state, which undoubtedly makes workload and difficulty of sampling increase, and is not conducive to field sampling. However, no matter which water layer, sampling in turbulent state can get closer results, and will not produce larger deviation. Therefore, according to the results of this research, turbulent section is preferred in the choice of wastewater sampling location, and avoids laminar flow section. This research is consistent with other research results, and can provide theoretical guidance for the choice of wastewater sampling location.
