Description
Technical field
The present invention relates to river regulation technical field, more particularly to a kind of river bottom mud administering method on the spot.
Background technology
With《City black and odorous water renovation guide》Issue, the improvement of black and odorous water in China exists
In progress like a raging fire, the areas such as bigger Haikou, Foochow are especially influenceed in recent years.In governance process, desilting is dredged
The river bottom mud for dredging out increasingly attracts people's attention.The polluted bed mud quantity in waters is quite big, and constant real estate
It is raw, if do not cleared up, it will gradually spread whole river course waters.It is contemplated that forthcoming years river lake and offshore waters comprehensive improvement
And substantial amounts of Dredged bed mud will be produced in water environment engineering turn into and be difficult to the reality avoided.
Because the riverbed sludge moisture content of dredging out is high, low intensity, also contain poisonous and harmful substance sometimes, its is rational
Processing is increasingly paid close attention to by each side.With the horizontal raising of urban industry and resident, river, channel, pipeline, lake,
In the waters such as reservoir and coastal waters import sewage quantity increase year by year, carried in these sewage many heavy metals, organic matter, N,
The pollutants such as P, under a series of physical chemical thermogenesis, a part of accumulation of pollutants causes bed mud dirty into riverbed sludge
Dye.When being handled using conventional method the river bottom mud that these dredge out, the poisonous and harmful substance that bed mud contains is such as
What is killed, and how the heavy metal pollution problem in river bottom mud is controlled, and is increasingly taken seriously.
The content of the invention
The purpose of the present invention is intended at least solve one of described technological deficiency.
Therefore, it is an object of the invention to propose a kind of river bottom mud administering method on the spot, solves river training bed mud
The problem of refractory reason, effectively administered on the spot.
