The content is generally in the industry sewage treatment will encounter the problem of biochemical oxygen demand, if the high value cannot meet the national requirements of sewage, why high cannot discharge?

Biochemical oxygen demand refers to a certain period, microbial decomposition of a volume of water some can be oxidized material, especially the amount ofdissolved oxygen consumption of organic matter. It is a comprehensive index reflecting the content of organic pollutants in water. Biochemical oxygen demandin water is high, the high consumption of oxygen, dissolved oxygen in waterdecreased, water quality of various animal, plant, microorganism and so on will die, the water will produce odor, produce toxic and harmful substances and so on, if the people eating the contaminated animal or plant, will cause harm to the human body can not be a.
