For the ease of observing inner case, 1 porthole of the filter tank arranged outside of said packing layer.
Preferred filter tank shape, said filter tank xsect is rounded, square or rectangle.
Preferably, the spacing between the said adjacent thief hole is 300mm.
Preferably, said ceramics filling layer and mixolimnion account for more than 50% of packing area height, below 85%.
The utility model principle of work: the air that mixes foul smell arrives in the filter tank through blower fan and inlet mouth; Sewage arrives in the filter tank through peristaltic pump and water-in, and the inboard, filter tank is provided with the air water break plate on inlet mouth and water-in, loads ceramics filling above the air water break plate; The coarse particles gac that mixes and the composite bed of iron filings recharge above the ceramics filling; Owing to the effect of blower fan and peristaltic pump, move to top, filter tank, behind air and the sewage entering filter tank through after the filtration of ceramics filling, coarse particles gac and iron filings; Pass through deodorization carrier grid then; Immobilized spherule is equipped with in deodorization carrier grid the inside, and immobilized spherule carries out deodorization to foul smell to be handled, and the gas of handling is discharged from the air outlet; Discharge from water outlet through triangle effluent weir filtered sewage, understand different heights to sewage treatment effect through thief hole is set.When blower fan and wriggling air pump inoperative, open drain, sewage is discharged from drain owing to the effect of gravity.
The utility model has following advantage and effect with respect to prior art:
1, utilizes the filler (haydite, coarse particles gac and iron filings) of multiple particle size range, avoid stopping up the appearance of hanging down phenomenon with processing efficiency.
2, deodorization carrier grid is set, in the deodorization carrier grid immobilized spherule is housed, carry out gas sweetening when can realize and handle WWT.
3, filtering net is set on thief hole, filler flows out through thief hole when preventing to sample.
4, gas-collecting cap is set, the gas after can effectively collection and treatment.
5, the mikrobe on comprehensive utilization filler and the immobilized spherule can effectively adapt to the variation of inlet gas concentration, improves capacity of resisting impact load.
