Existing similar water treatment device all adopt the light plastic ball of 2-3MM diameter do filtrate last floating aeration biological filter device, because filtering layer is thicker, pile up closely, though low-concentration organic waste water is had reasonable treatment effect, but the resistance to flow of water and gas is big, watt consumption height, the waste water higher to COD concentration, block easily, back flushing is frequent.
The utility model content
The purpose of this utility model is to overcome the problem that prior art exists, and provides a kind of difficult obstruction, the last floating band filtering layer fluidized bed bio reactor that watt consumption is low, effluent quality is good.
The utility model purpose is achieved through the following technical solutions:
Last floating band filtering layer fluidized bed bio reactor comprises reactor shell, water inlet pipe, intake pump, water-distributing device, gas blower, filter, filter plate, effluent weir, water outlet, aeration valve and back flushing outlet valve; Reactor shell is columnar structure or the square structure that has cavity, and the lower end of cavity is provided with water-distributing device, and the upper end of cavity is provided with filter plate, and filter is arranged on the filter plate, and the upper end of filter plate is provided with effluent weir, and effluent weir is connected with water outlet; The water-distributing device lower end is a hollow structure to the reactor shell bottom, and water inlet pipe is connected with intake pump, and intake pump inserts this hollow structure by pipeline; To this hollow structure, the pipeline that connects the gas blower hollow structure is provided with the aeration valve to gas blower by pipe connection; This hollow structure bottom also is provided with the back flushing outlet valve; Filter plate is to filled plastics foam ball filler between the water-distributing device and plastic hoop filler in the reactor shell; Wherein, the plastic hoop packing material size is 8-15mm, is positioned at the water-distributing device upper end, the lower end of plastic hoop filler, and the packing height of plastic hoop filler is 2-3m; The particle diameter of plastic foam ball filler is 2-5mm, is positioned at the filter plate lower end, the upper end of plastic hoop filler, and the packing height of plastic foam ball filler is 0.8-1.2m.
For further realizing the purpose of this utility model, the packing height of described plastic foam ball filler is preferably 1m.
The density of described plastic hoop filler is preferably 0.8-0.9g/cm
3
The density of described plastic foam ball filler is preferably 0.02-0.05g/cm
3
The utility model has following advantage with respect to prior art:
(1) employing size in the utility model top is 2-5mm, density be the plastic foam ball filler of 0.02-0.05g/cm3 as carrier, can increase the specific surface area of filtrate, increase amount attached to the microorganism on the carrier, filtration simultaneously guarantees effluent quality.
(2) the plastic hoop filler is adopted in the utility model bottom, its voidage is very high, greatly reduce the resistance to flow of water and gas, simultaneously, because the voidage height, the dirt-carrying amount is big, also be difficult for blocking,, thereby reduced the frequency of back flushing owing to the antiblocking ability strengthens greatly, also can improve the water environment capacity of fluidized-bed, prolong the periodic duty time of fluidized-bed.Greatly reduce and only use the high shortcoming of upflowing BAF air water resistance to flow now, can reduce the processing energy consumption of waste water.
(3) device of the present utility model can be handled the higher organic waste water of COD concentration of waste water.
Description of drawings
Fig. 1 is last floating band filtering layer fluidized bed bio structure of reactor synoptic diagram.
Embodiment
The utility model is described in more detail below in conjunction with accompanying drawing, but the claimed scope of the utility model is not limited to the scope of embodiment statement.
As shown in Figure 1, last floating band filtering layer fluidized bed bio reactor comprises reactor shell, water inlet pipe 1, intake pump 2, water-distributing device 3, gas blower 4, filter 5, filter plate 6, effluent weir 7, water outlet 8, aeration valve 9, back flushing outlet valve 10, plastic hoop filler 11 and plastic foam ball filler 12.Reactor shell is columnar structure or the square structure that has cavity, and the lower end of cavity is provided with water-distributing device 3, and the upper end of cavity is provided with filter plate 6, and filter 5 is arranged on the filter plate 6, and the upper end of filter plate 6 is provided with effluent weir 7, and effluent weir 7 is connected with water outlet 8; Water-distributing device 3 lower ends are hollow structure to the reactor shell bottom, and water inlet pipe 1 is connected with intake pump 2, and intake pump 2 inserts this hollow structure by pipeline; To this hollow structure, the pipeline that connects gas blower 4 and hollow structure is provided with aeration valve 9 to gas blower 4 by pipe connection; This hollow structure bottom also is provided with back flushing outlet valve 10; Filter plate 6 is to filled plastics foam ball filler 11 and plastic hoop filler 12 between the water-distributing device 3 in the reactor shell; Wherein, plastic hoop filler 12 particle diameters are 8-15mm, and density is 0.8-0.9g/cm
3, be positioned at water-distributing device 3 upper ends, the lower end of plastic hoop filler 11, the packing height of plastic hoop filler 12 is 2-3m; The particle diameter of plastic foam ball filler 11 is 2-5mm, and density is 0.02-0.05g/cm
