Description
Technical field
The invention belongs to pollution waters restoration technical fields, and in particular to a kind of black and odorous water bed mud dry powder renovation agent and its
Preparation method and application.
Background technique
The reason of black and odorous water, is mainly from sanitary sewage, industrial wastewater, livestock and poultry cultivation containing a large amount of organic pollutants
The excessive emissions of waste oil in the xenobiotic pollutants such as waste water matter and shipping process.Excessive organic pollutant is discharged into water body, by water
Raw biological metabolism decomposition, the rapid oxygen consumed in water, make overlying water anoxic, after dissolved oxygen content is lower than 0.2mg/L,
Water body enters anaerobic state, and anaerobe mass propagation in water body has decomposed the organic pollutant in water, and then generated tool
The escaping gas such as ammonia, hydrogen sulfide, the mercaptan of foul smelling smell, and the objects such as a large amount of humus absorption FeS and MnS in water body
Suspended matter is formed after matter, and results in water body nigrescence.Meanwhile suspended matter is in floating-upward process, and by bottom black bed mud band
Enter in overlying water, causes overlying water nigrescence, smelly phenomenon more prominent.The appearance of black and odorous water exacerbates current water quality
Type water shortage status causes more serious water resources crisis.
The reparation of black and odorous water bed mud can be divided into peripheral doses, chemical remediation and biological prosthetic three classes according to reaction mechanism,
Usually in combination using these three types of restorative procedures.
The peripheral doses of bed mud mainly desilt and dredge, diversion dilution is washed away, the methods of stability material covering.Traditional
Improving the most direct way of black and odorous water phenomenon is to carry out bed mud to desilt and dredge, but the bed mud with water is desilted and dredged construction work amount
Greatly, moisture content is high, volume is big, importantly, dredging will also destroy the original ecological balance of water bottom, has seen in the short time
Black smelly to eliminate, still, due to causing black smelly water condition and bottom mud microbe not to change, bed mud is black after a period of time
Smelly phenomenon will reappear, and the case where field disturbance and strange land pollution occur.Masking cover be polluted bed mud and overlying water it
Between using covering material keep apart muddy water interactive interface, and utilize the physical absorption between covering material and deposit, waterpower screen
The physical actions such as barrier, passivation cover the polluter in bed mud can not directly up again in water body and dissolve, spread, can effectively prevent
Only bed mud is to overlying water secondary pollution, to reach repairing effect, but the repair mode for sheltering covering will also change raw water
The ecological environment of body damages the balance of original aquatic ecosystem.
The chemical remediation technology of bed mud is mainly by adding chemical agent into bed mud, by changing the oxidation of water body also
The environmental factors such as former current potential, pH value influence the release of polluter, or by directly generating redox, blunt with chemical agent
The chemical reaction such as change, makes the polluter in deposit be removed or be stabilized, but adding for chemical agent is possible to change
The characteristics such as the oxidation-reduction potential of water body destroy original ecological environment to a certain extent, long-term inappropriate add instead
It will lead to bed mud thickening, and constantly add chemical agent and be also required to put into a large amount of rehabilitation expense.
The bioremediation technology of bed mud is by outer in water body plus screening microorganism or water plant etc., artificially by force
The intensity for changing microorganisms in water, water plant and the quantity of animal and proliferation and metabolism, so that the pollutant in water body gradually be divided
Solution is the substance of small molecule and progressively reaches water remediation, constructs the purpose that new water ecology balances, therefore the effect repaired
Duration is long and expense is relatively low.But it is added in the past since the microorganism of black and odorous water reparation is mainly liquid bacterial agent
Into water body due to the fixation matrix of shortage microorganism, additional microorganism is easy to be lost as water flow flows, and largely effects on
The effect repaired, needs to be continuously replenished and adds microbial inoculum to maintain preferable repairing effect.
Summary of the invention
It is an object of the invention to by preferably having degradation to organic pollutants such as nitrogen phosphorus in black and odorous water etc.
Microorganism, and cooperate special preparation, porous light microbe carrier, microorganism is fixed on carrier, and dry powder is made
The form of preparation.Dry powder is applied in water body and bed mud to be repaired, in the process that preparation is gradually settled, contacted with water body
In, so that Immobilized Growing is gradually bred in water body in the microorganism on carrier.It is prepared into porous carrier-microorganism composite dry
The form of powder will substantially reduce the cost that microorganism formulation is saved and transported, and since repair vector is special porous material,
With denitrogenation dephosphorizing and other effects, after entering bed mud, by the organic contamination of the microorganism Synergistic degradation water body with apposition growth
Object, to achieve the purpose that the good ecological environment of building, the black smelly bed mud of successive elimination and its overlying water.
The technical scheme is that：
