水体污染后，常可引起水的感官性状恶化，如某些污染物在一定浓度下，对人的

Pollution of the water body can often cause deterioration of the sensory properties of the water. For example, certain pollutants at a certain concentration may not directly harm human health, but can cause the water to produce odor, color, foam and oil film, etc. Normal use of water bodies. Copper, zinc, nickel and other substances can inhibit the growth and reproduction of microorganisms at a certain concentration, thereby affecting the decomposition and biological oxidation of organic matter in the water, reducing the self-purification ability of the water body, and affecting the sanitary condition of the water body.

After water pollution, it can often cause the deterioration of the sensory character of water, such as certain pollutants at a certain concentration, although there is no direct harm to human health, but can make water odor, color, foam and oil film, etc. , hindering the normal use of water bodies. Copper, zinc, nickel and other substances can inhibit the growth and reproduction of microorganisms at a certain concentration, thus affecting the decomposition of organic matter in water and biooxidation, so that the self-purification capacity of water bodies decreased, affecting the health status of water bodies.

After water pollution, the sensory properties of water can be deteriorated. For example, certain pollutants have no direct harm to human health under certain concentrations, but they can cause odor, color difference, foam and oil film, which will impede the normal use of water. Copper, zinc, nickel and other substances in a certain concentration can inhibit the growth and reproduction of microorganisms, thus affecting the decomposition and biological oxidation of organic matter in water, reducing the self purification ability of water body and affecting the sanitary condition of water body.
