High-turbidity water quality emergency treatment technology

Abstract

The invention belongs to the field of water environment management and relates to a high-turbidity water quality emergency treatment technology. Especially, a synergistic effect of a modified clay mineral material and a microorganism is utilized, and the modified clay mineral material and the microorganism, and pollutants including suspended particles, nitrogen and phosphorus and the like in a water body are subjected to adsorption, flocculation and decomposition, so that the turbidity is rapidly reduced and the water quality is purified; furthermore, the effect of improving the transparency of the water body is achieved; the emergency treatment technology has the advantages of simple management technology, rapid effect, good effect and low cost, can be widely applied to emergency treatment of long-time high turbidity at a management initial period of a black and odorous river channel and after water is drained into a river, and can also be applied to the emergency treatment at a rainwater period after the black and odorous river channel is managed and when river water is turbid and pollutants are increased.

Description

technical field [0001] The invention belongs to the field of water environment treatment, and relates to a high-turbidity water quality emergency treatment technology, which utilizes the synergistic effect of modified mineral materials and microorganisms to reduce the turbidity of river water quickly and at low cost, and purify the water quality. Background technique [0002] With the rapid development of my country's economy and the acceleration of urbanization, the problem of river water pollution in the urban areas of my country has become more and more serious. The black and smelly water body also causes serious adverse effects on the environment. At the same time, the aggravation of water pollution in urban polluted rivers directly affects the urban environment around the rivers and the development of urban social economy. Therefore, the governance of urban rivers, especially the control of water pollution in urban rivers, is urgent. With the publication of the "Water ...

Problems solved by technology

[0004] At present, although there are many technical solutions for the treatment of black and odorous rivers, some of which are relatively mature, there are relatively few researches on new materials and new technologies for the problem of river water turbidity after river treatment, especially for water diversion after river treatment. In the early stage of the river, the river water will be turbid for a long period of time, and the bottom of the river will not have enough light, which is not conducive to the growth of water organisms and the construction of the ecosystem; followed by the rainy period, the rainwater will carry the river (lake) bank sediment into the river, causing the river water to be turbid. Settlement, with a long period, is likely to cause damage to the water ecosystem

At present, most of them simply add flocculants to reduce turbidity. First, the effect is single and only for suspended particles; second, the dosage is large, the cost is high and the load on the environment is large; One process; the fourth is that it cannot provide a carrier for microorganisms
