Abstract
The utility model relates to the technical field in filter tank, particularly relates under one to stream BAF.This lower to stream BAF comprise sewage water inlet pipe, aeration tube, process rising pipe, packing layer, anti-gas-filled valve, washback drainpipe and backflushing water intake pipe, sewage water inlet pipe is placed in the upper end in filter tank, the side in filter tank is provided with aeration tube and process rising pipe, the bottom of filter tank opposite side is provided with anti-gas-filled valve and backflushing water intake pipe, the upper end of filter tank opposite side is provided with washback drainpipe, in filter tank, be provided with packing layer.This lower structure to stream BAF is simple, has the function retaining suspended substance and the biological sludge come off in raw waste water, therefore, without the need to establishing settling tank, floor space is few, can keep a large amount of biomasss in pond, again due to crown_interception, good sewage processing effect.
Description
Technical field
The utility model relates to a kind of biological filter, particularly relates under one to stream BAF.
Background technology
In prior art, the process of sewage uses microbial film, sewage and biofilm contact, dirty organic pollutants is as nutritive substance, and absorbed by the Institute of Micro-biology on microbial film, sewage is purified, microorganism self is also bred, technique filter tank structure for treating sewage by using biological membrane is various, but mostly there is complex structure, safeguards inconvenient problem.
Utility model content
The utility model is intended to address the aforementioned drawbacks, and provides under one to stream BAF.
In order to overcome the defect existed in background technology, the utility model solves the technical scheme that its technical problem adopts: thisly comprise sewage water inlet pipe, aeration tube, process rising pipe, packing layer, anti-gas-filled valve, washback drainpipe and backflushing water intake pipe to stream BAF down, sewage water inlet pipe is placed in the upper end in filter tank, the side in filter tank is provided with aeration tube and process rising pipe, the bottom of filter tank opposite side is provided with anti-gas-filled valve and backflushing water intake pipe, the upper end of filter tank opposite side is provided with washback drainpipe, in filter tank, be provided with packing layer.
According to another embodiment of the present utility model, comprise the bottom that described process rising pipe, anti-gas-filled valve and backflushing water intake pipe are placed in packing layer further.
The beneficial effects of the utility model are: this lower structure to stream BAF is simple, there is the function retaining suspended substance in raw waste water and the biological sludge come off, therefore, without the need to establishing settling tank, floor space is few, can a large amount of biomasss be kept in pond, then due to crown_interception, good sewage processing effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Wherein: 1, sewage water inlet pipe, 2, aeration tube, 3, process rising pipe, 4, packing layer, 5, anti-gas-filled valve, 6, washback drainpipe, 7, backflushing water intake pipe.
Embodiment
Fig. 1 is structural representation of the present utility model, figure comprises sewage water inlet pipe 1, aeration tube 2, process rising pipe 3, packing layer 4, anti-gas-filled valve 5, washback drainpipe 6 and backflushing water intake pipe 7, sewage water inlet pipe 1 is placed in the upper end in filter tank, the side in filter tank is provided with aeration tube 2 and process rising pipe 3, the bottom of filter tank opposite side is provided with anti-gas-filled valve 5 and backflushing water intake pipe 7, the upper end of filter tank opposite side is provided with washback drainpipe 6, is provided with packing layer 4 in filter tank.Process rising pipe 3, anti-gas-filled valve 5 and backflushing water intake pipe 7 are placed in the bottom of packing layer 4.
Place the small-particle of 3-5mm in packing layer 4 as filler, its surface-area is large, and microorganic adhesion power is strong, and gas-liquid fully contacts in the gap of packing layer 4, and because gas, liquid, solid three contact, oxygen transfer rate is high, and power consumption is low; Without the need to sludge reflux, also without the filter of sludge bulking, integrally-built maintenance management is also very convenient.
