Why is there a black odor water body?
When urban water bodies can be effectively protected, economic development can get a more solid foundation, the city's sustainable development goals can be effectively achieved. To black smelly water treatment then, you have to know the reason, black smelly water produced by more reasons, mainly from the following aspects of its generalization:
Why there will be black odor water body?
1, hydrodynamic conditions lead to factors
As one of the more important factors in the water body, hydrodynamic conditions often lead to the emergence of black odor phenomenon of water bodies, mainly due to poor water circulation, directly affecting the water samples of the water body, the water body caused by different degrees of pollution, when the water quality of the water body deterioration of the water body will be black odor.
2, metal element pollution
When a large number of iron and manganese elements and other substances in the water, in the case of insufficient oxygen will appear reduction phenomenon, making iron and manganese substances and sulfur substances in the water to react to form ferrous sulfide and manganese sulfide and other substances, resulting in black odor of the river water phenomenon.
3、Organic pollution factors
For the black odor phenomenon in the water body, the root cause of the black odor phenomenon is a biochemical reflection of the phenomenon, the organic matter in the water body in the state of oxidative decomposition, the rate of oxygen consumption rate is significantly higher than the rate of oxygen reoxygenation, resulting in more and more pronounced hypoxia phenomenon within the body of water, and anaerobic microorganisms in the water body in the state of decomposition will produce hydrogen sulfide, methane or ammonia and other malodorous pollutants, will lead to the body of water in the course of time. Blackening and odor phenomenon is obvious.
