[0002] Water quality is the abbreviation of water quality. It indicates the physical (such as color, turbidity, odor, etc.), chemical (inorganic and organic content) and biological (bacteria, microorganisms, plankton, benthic organisms) characteristics of water and its composition. Water quality is the condition of evaluating the quality of water. It stipulates a series of water quality parameters and water quality standards, such as water quality standards for drinking water, industrial water and fishery water, and the physical and chemical properties and dynamic characteristics of natural water that is not polluted by human activities. The physical properties mainly refer to the temperature, color, transparency, smell and taste of water.
