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，可使水

Water pollution can often cause deterioration of the sensory properties of the water. For example, certain pollutants at a certain concentration can cause the water to produce odor, color, foam and oil film, etc., which hinder the normal use of water. Copper, zinc, nickel and other substances at a certain concentration will inhibit the growth and reproduction of microorganisms, thereby affecting the decomposition and biological oxidation of organic matter in the water, reducing the self-purification ability of the water body, affecting the sanitary condition of the water body, and causing a certain impact on the water quality.

After water pollution, it can often cause the deterioration of the sensory character of water, such as certain pollutants at a certain concentration, can make water odor, color, foam and oil film, etc. , hindering the normal use of water bodies. Copper, zinc, nickel and other substances in a certain concentration will inhibit the growth and reproduction of microorganisms, thereby affecting the decomposition of organic matter in water and biooxidation, so that the self-purification capacity of water bodies decreased, affecting the health of water bodies, water quality has a certain impact.

After water pollution, the sensory properties of water can be deteriorated. For example, certain pollutants can cause odour and discoloration of water, such as foam and oil film, which will impede the normal utilization of water. Copper, zinc, nickel and other substances in a certain concentration will inhibit the growth and reproduction of microorganisms, thus affecting the decomposition and biological oxidation of organic matter in water, reducing the self purification capacity of water body, affecting the health status of water body and causing certain impact on water quality.<br>
