Technical Field

The utility model relates to a water purification treatment equipment, especially a special equipment is administered to black smelly water in city inland river.

Background

With the improvement of the modern industrialization level, the pollution of urban inland river water bodies is increasingly serious. Among them, black and odorous water is a common pollution phenomenon in which the self-purification function is lost. Investigation shows that a large amount of organic matters contained in the industrial wastewater are main pollution sources of black and odorous water, and the organic matters generate malodorous after complex anaerobic fermentation and putrefactive decomposition under the condition of insufficient oxygen supply to the water, so that the ecological environment and the human health are harmed.

At present, treatment measures for black and odorous water mainly comprise control of pollution sources, improvement of purified water quality, ecological restoration in water and the like. Among them, the principle of action of repair can be divided into physical, chemical and biological methods. Most pollution sources can be timely and effectively removed by using physical methods such as filtration, precipitation and adsorption, but nitrogen and phosphorus nutrient salts in the water body are not completely removed. The chemical treatment agent can be used for coagulating and neutralizing pollutants and further converting the pollutants into nontoxic and harmless substances, and secondary pollution is caused to a greater or lesser extent. The biological agent is a relatively extensive water body remediation mode in recent years, and has multiple advantages of high efficiency, radical treatment, avoidance of secondary pollution and the like.

Inland river clarification plant based on above-mentioned prior art exists that the volume is great, and the structure is complicated, with high costs, and medicament recycle is relatively scarce, and nitrogen phosphorus nutritive salt gets rid of thoroughly scheduling problem inadequately in the water.
