In the urban operation process, if the phenomenon of the black and odorous water body is serious, the water quality can be polluted, the odor can be emitted, and the quality of the ambient air can be influenced. Black and odorous water is an extreme manifestation of water environments suffering from organic pollution that exceeds their self-cleaning capabilities. The water body is obviously blackened and accompanied with odor, plankton in the water is basically absent, aquatic plants are seriously degraded, a food chain is broken, the water body ecology is unbalanced, and the function is basically lost. The black and odorous water has great damage effect on urban ecology, and further influences the daily life of vast citizens.

In the process of treating black and odorous water, the enhanced flocculation in chemical treatment is the most obvious effect, and by spraying a flocculating agent and adopting a flocculation precipitation technology, water particulate matters and soluble toxic and harmful substances are subjected to natural coagulation precipitation to quickly improve the water, and the water health is gradually recovered by transferring and converting precipitates. However, in the actual process, the cost of spraying the flocculating agent is low, and the construction cost of collecting, transferring and converting sediments is high, so that equipment which specially occupies a large amount of fields is needed. Therefore, in reality, the cleaning of the powder is an urgent chapter in order to deal with the inspection. Some flocculants contain copper sulfate, flocculants and other medicaments, the water is clear quickly, but copper ions and other chemical substances in the flocculants are mixed in flocculating precipitates and settle at the bottom of the water body and sludge, so that the survival of aquatic organisms is influenced, the water ecology is damaged, the water body still has no self-cleaning capacity, and the water body is turbid or black and smelly after a period of time.
