Description
Technical field
The present invention relates to the field of purification of water body, and in particular to suitable for preventing or river training, the black and odorous waters such as lake
Method and this method use cleanser.
Background technique
Under the modern civilization of high development, the discharge of industrial wastewater and municipal sewage and domestic water is a large amount of to pollute
The untreated inflow rivers of substance, lake make river water become eutrophic water body by organic contamination, and microorganism is in the water body
Oxygen consumption mass propagation, the oxygen in water made are consumed totally, lead to water hypoxia, large amount of organic is by anaerobic biological decomposition shape
At odorants such as a large amount of sulfide, organic amine and organic acids, water body is caused to foul, under anoxic and anaerobic condition, in water body
The metal ions such as iron, manganese and water in sulphion form ferrous sulfide, the compounds such as manganese sulfide cause water body blackening.Urban black
Smelly water body not only brings very poor sensory experience to the masses, and directly affects the protrusion water environments of masses' production and living and ask
Topic.Black and odorous water, reply self-purification of water function how is effectively inhibited to have become urgently to be resolved in water environment pollution control ask
Topic.
The regulation of city black and odorous water should be according to " dirty, endogenous improvement is cut in control source；Running water circulation, clear water supply；Water quality is net
The basic fundamental route specific implementation of change, restoration of the ecosystem ", wherein it is selection other technologies type that dirt and endogenous improvement are cut in control source
Basis and premise.However, at present in terms of the regulation of black and odorous water research is concentrated mainly on improvement, although having more report
Road, such as the technology of common inhibition black and odorous water includes Sediment Dredging, biological prosthetic, artificial aeration etc..However, the prior art
In Treatment process be constantly present such or such problem, such as Sediment Dredging is controlled by excavating the polluted bed mud on surface layer
With reduce black smelly source, but Sediment Dredging engineering amount is big, at high cost, will cause certain destruction to water ecosystem；
Microorganism remediation preparation is at high cost, and the shelf-life is short, and effect slowly, is also limited by water environment conditions, it is difficult to a wide range of to use；Plant
The repairing growth period is long, needs timing to gather in, practical function is unobvious, and artificial aeration can quickly increase content of oxygen dissolved in water, right
Inhibit black and odorous water to have a good result, but the technical costs is high, oxygen utilization efficiency is lower, phytal zone using when be also possible to make
It is turned at bed mud, discharges certain pollutant.If can effectively realize that dirt is cut in control source, being bound to can be greatly reduced the later period is controlled
The difficulty and cost of reason.However so far, the technology that dirty aspect is cut for how effectively to control source is rarely reported.
Summary of the invention
