Abstract
The invention discloses a method for the in-situ control of phosphorus release from eutrophic water bottom sediment, which comprises: allowing solution of ozone and calcium chloride to act on an eutrophic water bottom sediment-overlying water interface, so that the calcium chloride can quickly react with phosphorus on the surface interface of lake bottom sediment under a strong oxidizing condition formed by the ozone to reduce the phosphorus content of the overlaying water and form a physical covering layer on the surface of the lake bottom sediment for further inhibiting the phosphorus release from the bottom sediment. Thus, the in-situ control of the phosphorus release from eutrophic lake bottom sediment is realized. Compared with the prior art, the method of the invention has the advantages of convenient operation, low cost and obvious and long-lasting effect. The method can be widely used in water with relatively small flowability such as water in lake and pond. The method represents a new approach for the in-situ remediation of eutrophic water bottom sediment.
Description
(1) technical field
The present invention relates to water environment pollution and administer the field, be specifically related to a kind of original position that is used for and administer the method that the eutrophic water body sedimentary phosphate discharges.
(2) background technology
Studies show that in a large number phosphorus is the restricted factor of body eutrophication, how to reduce the content of phosphorus in the water body effectively and be one of key that eutrophication water administers.Phosphorus in the water body can be divided into external source phosphorus and endogenous phosphorus according to the source.External source phosphorus comprises the phosphorus element of multiple movable input such as runoff, atmospheric precipitation, industry and sanitary sewage discharging; Endogenous phosphorus refers to the phosphorus element of water body inside, mainly comes from the residual body after water body bed mud and the aquatic animals and plants death.Because the content of phosphorus is bigger in the eutrophic water body bed mud, therefore, bed mud often is called as " phosphorus storehouse ", is the key of endogenous phosphorus control.
For the endogenous phosphorus such as phosphorus in the bed mud, the main at present technology such as chemical precipitation method, biological process, physisorphtion that adopt.Biological process mainly is to utilize polyP bacteria to absorb phosphorus, removes phosphorus in the water by the method for spoil disposal, and this method is little, effective to the benthic environment influence, but this method exist the polyP bacteria growth be subjected to the bed mud environmental influence big, be difficult for shortcoming such as inoculation.Chemical precipitation method mainly is to form the insoluble phosphate throw out by adding chemical agent, phosphorus is fixed, the oxidated reductive condition influence of this method is bigger, the eutrophication water dissolved oxygen content is lower usually, especially interface, bed mud top layer anaerobic environment often is unfavorable for the generation of chemical precipitation reaction.Physisorphtion is to utilize the absorption avidity of the solid matter of some porous or large specific surface to phosphate radical in the water, realize the dephosphorization process, this method is subjected to the bottom-dwelling disturbing influence easily, the bed mud interface that the bottom-dwelling activity is stronger, traditional physisorphtion can't be controlled the bed mud that causes because of bioturbation effectively and discharge.At present, be badly in need of lasting, the easy to operate bed mud of a kind of effect and discharge control techniques.
(3) summary of the invention
The technical problem to be solved in the present invention be to provide a kind of operate facility, with low cost, effect is remarkable and the plain control method that discharges of persistent original position bottom mud in lake phosphorus.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of original position that is used for is administered the method that the eutrophic water body sedimentary phosphate discharges, described method is: make ozone and calcium chloride solution act on eutrophic water body bed mud-overlying water interface, calcium chloride under the strong oxidizing condition that ozone forms with the phosphorus rapid reaction on bed mud surface, thereby phosphorus content and form the physics tectum on bed mud surface in the reduction overlying water, further suppress sedimentary phosphate and discharge, thereby realize the original position of eutrophic water body sedimentary phosphate release is administered.
The action principle of technique scheme of the present invention is: carry out the strong oxidizing condition of ozonation aerated formation, ozone can impel various form phosphorus efficiencies in calcium chloride and the bed mud, combine fast, reduces the overlying water total phosphorous; And unreacted calcium chloride completely can form one deck physics tectum on the bottom mud in lake surface with the precipitated product that reaction back forms, and both can isolate water sludge interface, and performance physics presses down the effect of phosphorus, can continue again with bottom mud in lake in the phosphorus reaction that discharges; In addition, ozonation aeratedly also can suppress the bottom-dwelling perturbation action, and then suppress the release that sedimentary phosphate causes because of bioturbation.
Among the present invention, need make ozone and calcium chloride solution need act on bed mud-overlying water interface, can be accomplished in several ways, as ozone being provided by ozonizer and importing at bed mud-overlying water interface aeration, use dosing pump to bed mud-overlying water interface injection calcium chloride solution, as long as make the active position of ozone and calcium chloride solution at bed mud-overlying water interface.In mechanism, can be carry out earlier ozonation aerated, and then the injection calcium chloride solution; Also can be ozonation aerated and the injection calcium chloride solution carry out simultaneously.The preferred elder generation of the present invention carries out ozonation aerated to bed mud-overlying water interface, aeration finishes the back at once to bed mud-overlying water interface injection calcium chloride solution.The present invention specifically recommends to use a kind of aeration dosing all-in-one, comprise a framework movably, air aeration unit, ozone generating unit, dosing pump, soup hold-up vessel are installed on the described framework, the ozone effusion pipeline of described ozone generating unit is connected with the composite aeration head with the unitary air effusion of air aeration pipeline serial connection back, described soup hold-up vessel is communicated with dosing pump by pipette, the soup of described dosing pump overflows pipeline and is connected to the composite aeration head, and the surface of described composite aeration head is provided with the soup escape orifice.
Further, described ozone effusion pipeline, air effusion pipeline, soup overflow pipeline and all dispose under meter and valve.
Further, described framework is the stainless steel support body that has roller, which is provided with pushing hands and gas-liquid pipe hanger hook.
Further, described soup hold-up vessel is the cylindrical hollow plexi-glass tubular.
Further, described composite aeration head is a stainless steel component.
