Description

Black and odorous water body improves processing apparatus in lake

Technical Field

The invention belongs to the field of sewage treatment, and particularly relates to a treatment device for improving black and odorous water in lakes.

Background

Water resources are indispensable important resources for human life and work, but as the urban development speed in China is increased continuously, partial sewage is discharged into lakes to cause serious black and odorous phenomena to the lakes, and the ecology is seriously influenced.

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.
