Description
Technical field
The present invention relates to field of environment engineering, more particularly to a kind of basin water ecological original position dredging repair system and side
Method.
Background technique
The ecological functions and regulatory function in present water system basin are with industrial development, mankind's activity, shortage of water resources, water
Pollution is seriously damaged, and forms polluted-water, or even form black and odorous water.Caused by black and odorous water is mainly water hypoxia,
Also related with water eutrophication and bed mud deposition simultaneously.The great water special project correlative study of country the result shows that, when dissolved oxygen is low
When to 2.0mg/L, water body will be in anaerobic condition.When dissolved oxygen is 3mg/L~5mg/L, organic matter and ammonia nitrogen contain in water body
General amount also can be more than ground Table V class standard, and presentation is coloured taste state, but with the presence of aquatile；When dissolved oxygen is greater than 6 mg/
When L, water body is in aerobic state, and organic matter degradation and ammonium oxidation rate dramatically increase, and water body starts with self-purification capacity.When
After water body is contaminated, some of the contaminants are accumulated over a long period, and enter water body bottom by settlement action or with particulate matter suction-operated
In mud.Under acid, reducing condition, pollutant and ammonia nitrogen are discharged from bed mud, and the methane and nitrogen that anaerobic fermentation generates cause
It is also the one of the major reasons of black and odorous water that bed mud, which floats,.Studies have pointed out that in some polluted-waters, pollutant in bed mud
Burst size is suitable with foreign aid's total amount of pollutants discharge.Furthermore there is a large number of nutrients in city river, lead to algae excessive propagation in river.
These algae are water body supplemental oxygen in early growth period, decompose mineral formation oxygen consumption organic and ammonia nitrogen after death, lead to season
The black smelly phenomenon of the section property fishy taste extremely strong with generation.Meanwhile lose the water body of ecological functions, often mobility reduce or
It completely disappears, directly results in the decline of water reoxygenation ability, it is serious that local waters or water lose oxygen problem, and it is quickly numerous to form matters algae
The hydrodynamic condition grown increases algal bloom risk, causes water quality and deteriorates.
In conclusion the method for prevention black and odorous water is mainly the dissolved oxygen content for increasing water body, however it is long-term contaminated
Water body self-purification ability it is low, even completely lost self-purification capacity formed black and odorous water water body will be unable under the conditions of oxygenation
Achieve the purpose that administer black smelly, is generally adopted for this kind of black and odorous water polluted at present and cut a dirt and receive pipe, dredging of shutting off, original position
Dredging etc. carries out cleaning bed mud, rebuilds ecosystem mode and is handled.Either shut off dredging, or desilting mode in situ is clear
Bed mud is managed, economic input amount is big, bed mud can only be shifted, the ecosystem rehancement difficulty big time is long, and mud generates
Secondary pollution needs to be further processed.
