Description
Technical field
The utility model relates to refuse disposal system, particularly a kind of percolate aeration treatment apparatus.
Background technology
The process of percolated liquid in city refuse landfill is unusual stubborn problem in Landfill Site Design, operation and management always.Percolate is the product that liquid flows at landfill yard gravity, is mainly derived from the interior moisture of precipitation and rubbish itself.Because liquid has many factors may have influence on the character of percolate in flow process, comprise physical factor, chemical factor and biotic factor etc., so the character of percolate changes in a sizable scope.Percolated liquid in city refuse landfill is a kind of high concentrated organic wastewater of complicated component, if do not add process and directly enter environment, can cause serious environmental pollution.For the purpose of protection of the environment, process is carried out to percolate and is absolutely necessary.
And existing percolate process Problems existing is mainly manifested in: 1 capacity of resisting impact load is poor.The metastable sewage water yield of Biochemical method sewage general requirement and water quality, and in waste treatment facility, in the wet season in rainy season, the capacity relative of equalizing tank is not enough, certainly will cause the impact to biological treatment system load, affect treatment effect; In low water season, diafiltration liquid measure is few, and the Pollutant levels such as ammonia nitrogen are high, inhibit microorganism growth.2 single creature treatment process bad adaptability.Along with the prolongation of landfill time, in percolate treating process rear end, occur nutritive element numerous imbalances, percolate carbon-nitrogen ratio declines, the problem of the biodegradability reduction of COD and TN.3 biological process decolourings quite difficulty.Containing a large amount of difficult degradation chromonic material in percolate, biological process is zero for the decolorizing effect of later stage tail water substantially.4 materializing strategy techniques can with the water quality and quantity fluctuation fast timely adjusting process parameter of response, and especially advanced oxidation processes has good treatment effect to the biodegradability aspect improving waste water, but it has shortcomings such as processing costs is high, complicated operation, energy consumption are high.
Summary of the invention
Technical problem to be solved in the utility model is: provide that a kind of coefficient of oxygen utilization is high, energy consumption is low, can efficiently process and the good percolate aeration treatment apparatus for the treatment of effect.
The technical scheme in the invention for solving the above technical problem is: a kind of percolate aeration treatment apparatus, it comprises oxidation reactor, aerating apparatus is provided with in described oxidation reactor, described aerating apparatus comprises and is vertically arranged at the cylindrical shell in the oxidation reactor of the second stage, motor, the elongated multiple aeration heads of the impeller rotated by driven by motor and the oblique both sides being symmetricly set in the bottom of cylindrical shell, described cylindrical shell upper, lower two ends are equipped with opening, described impeller is placed in the top of cylinder lumen, multiple aeration head is connected with the air outlet of two air compressor by the tracheae that two are vertically arranged in cylindrical shell.
Compared with prior art, the utility model has the advantage of: in the oxidation reactor of this percolate aeration treatment apparatus, be provided with aerating apparatus, aerating apparatus comprises upper/lower terminal and is equipped with opening and is vertically arranged at the elongated multiple aeration heads in cylindrical shell in the oxidation reactor of the second stage, motor, the impeller rotated by driven by motor and the oblique both sides being symmetricly set in the bottom of cylindrical shell, impeller is placed in the top of cylinder lumen, and aeration head is connected with the air outlet of two air compressor by the tracheae that two are vertically arranged in cylindrical shell.Second stage oxidation reactor is made up of two kinds of aeration structures, the structure being arranged so that aerating apparatus of cylindrical shell is more compact, the setting of motor and impeller, negative pressure can be formed in cylinder, and air compressor and aeration head the effect that fully can reach aeration aerating is set, and effectively can reduce liquor C OD, this percolate aeration treatment apparatus coefficient of oxygen utilization is high, can efficiently process, cost is low, and treatment effect is good.
As preferably, the quantity of described aeration head 5 is four, and described four aeration heads are uniformly distributed in the both sides of described cylindrical shell 2.Such Air Exposure better effects if.
As preferably, the bottom of described cylindrical shell is provided with the rack base for supporting.Like this, cylindrical shell can be maked somebody a mere figurehead, convenient circulation, better to the treatment effect bottom oxidation reactor.
As preferably, described aeration head and the angle of horizontal direction are 10-20 °.Like this, Air Exposure better effects if.
As preferably, the both sides of described cylindrical shell are equipped with inlet opening.Like this, facilitate the liquid circulation in cylindrical shell, Air Exposure better effects if.
