With the increasing attention to water quality safety, water quality testing has become an important task. So, what are the common water quality testing items?
First, let's take a look at the routine items of water quality testing. These items include pH, water temperature, turbidity, total suspended solids, chromaticity, odor and taste, conductivity, suspended solids, turbidity, total color measurement, and more. These indicators are important parameters that reflect the basic status of water quality, and by testing these indicators, we can understand the basic situation of the water body and judge whether it meets the standards for drinking water, industrial water or agricultural water.
In addition to the routine items, water quality testing includes many other important indicators. For example, total coliforms, heat-stable coliforms, and Escherichia coli are important indicators to reflect the bacterial content in water bodiesTotal residual chlorine is an important indicator of disinfectant residues in water bodiesHeavy metals such as lead, cadmium, and mercury are important indicators to reflect the content of heavy metals in waterNitrate is one of the important indicators of organic matter pollution in water bodiesChemical oxygen demand (COD) is one of the important indicators to reflect the organic matter pollution in the water bodyBiochemical oxygen demand (COD) is one of the important indicators to reflect the organic matter pollution in the water body.
In addition, the items of water quality testing will vary depending on the application and field. For example, for swimming pools and other water entertainment venues, water quality testing will pay more attention to the detection of turbidity, residual chlorine, total coliform bacteria and other indicators;For industrial water, water quality testing will pay more attention to the detection of pH, hardness, total organic carbon, chloride and other indicators.
In short, water quality testing is an important means to ensure the safety of water resources, and different water quality testing items can reflect the different conditions of water bodies. When conducting water quality testing, it is necessary to select appropriate testing items according to actual needs, so as to better understand the status of water bodies and ensure people's health and the safety of the ecological environment.
