Water environment protection field.
Background technology
Large-scale step hydraulic engineering can effectively adjust basin flood, reduce economy and ecological disruption of the flood to downstream.
During dam flood-discharge, strong turbulent fluctuation occurs for the lower stream that sluices, and causes the fragmentation of the current water surface, forms the countless globules so that aqueous vapor
Interface is sharply increased, and then the gas such as the nitrogen in air, oxygen is significantly increased by the quantity of aqueous vapor interface into water body, from
And make the content of downstream river course dissolved gas during dam flood-discharge horizontal apparently higher than natural river course.When a certain step dam upstream
When water body dissolved gas content is higher, downstream water dissolved gas is easily in supersaturation (Dissolved Gas
Supersaturation, DGS) state.
Supersaturated oxygen can return to native state by Physical Attenuation, chemistry decay and dilution in water body.And nitrogen
Gas dissolves the active very poor of nitrogen, it is believed that be not involved in typically chemically reacting, its decay then can only as inert gas in water body
Reach natural content by Physical Attenuation and diluting effect.And in the case of being imported at not new water source, dissolve nitrogen thing
It is often very slow to manage release process.Nitrogen supersaturation is dissolved in water body once occurring, returning to normality needs fairly long distance
Or the time.General dissolved gas content is paid close attention in water body compared to change in time and space of the content in water body of certain pure gas, tool
There are stronger science and ecological significance.
The concentration supersaturation of gas dissolved water can produce material impact to aquatile.It can not only destroy aquatile
Original living environment, break original ecological balance, can also directly result in some biologies and produce disease, such as dissolved in water
Nitrogen etc. enters in fish body, fish can be caused to suffer from " bubble illness " and dead.At the same time, fish are oversaturated exposed to gas
In water, its behavior will can be affected.Excessive bubble is attached on around fish body in water, especially into side line, can influence fish
Class causes fish to be disoriented in water and swims alter everywhere to the correct judgement of surrounding environment, and ability of moving about reduces, and
Easily become the food organisms of predacious fish.
The appearance of supersaturated gas problem, cause the concern of numerous domestic experts and scholar, a series of related alleviations
Also be suggested in succession with avoiding measures, a big chunk therein be an attempt to by reservoir operation realize disaster degree reduction or
Person eliminates.But due to the actual effect and complexity of step reservoir flood discharge dissolved gas physics and chemistry monitoring, and it is reliable in situ
Ecological effect is difficult to the problems such as measure, and the domestic early warning work about step reservoir flood discharge dissolved gas supersaturation disaster fails to have
Effect expansion, related basic imagination are also rarely reported.Therefore, step up to carry out basin-wide water body supersaturation study of warning, take conscientiously
Feasible measure avoids or reduced supersaturated gas and adversely affected to caused by the aquatic system of downstream, so as to realize dam downstream spy
There is the protection with economic fish imperative.
