Description
Technical field
The present invention relates to technical field of sewage, and in particular to a kind of activity bacterium mud screening washer.
Background technology
The conventional active sludge of biological treatment of existing sewage disposal system and biological contact oxidation process.Activated sludge process
Chi Rong great, sludge reflux is big, and sludge bulking easily occurs, and sludge flows back from second pond, because second pond main function is
Mud-water separation, hydraulic detention time length are carried out, the aerobic bacterium mud of backflow often enters simultaneous oxygen because long in the second pond residence time
Even anaerobic state, causes activated sludge strain poor activity, and after backflow, sludge self-dissolving, treatment effect is deteriorated, and has
The shortcomings of easy oxygen consumption；But activated sludge process small investment, it is simple in construction, it is easy to maintenance, turn into a kind of biological treatment generally used
Sewage method.Biological contact oxidation process, routine operation do not need sludge reflux, are less likely to occur sludge bulking, treatment effect phase
To preferable；Due to the debugging domestication operation reason before success biofilm, it is also necessary to which a large amount of sludge refluxes, biomembrane is because of sludge concentration
It is too high, easy oxygen consumption, reduce treatment effect；Increase the density of filler, investment is big, structure in design in order to increase contact surface simultaneously
Complexity, filler is more easy to aging and caking, maintenance are changed difficult；The active mycoderm of aging in contact oxidation method departs from filler and carried
Body, due to high-density packing, the technical problem such as separation difficulty.It is big sludge output to be all present in the operation of two kinds of technique, activated sludge with
Inactivated sludge is difficult to separate, and excess sludge easily causes the technical problems such as secondary pollution, poor processing effect.
So the problems such as mud-water separation, activated sludge separate with inactivated sludge, is to pass for the discharge capacity for reducing sludge
Important, mud-water separation is all using the sedimentation basin of cube point bucket, the mud-water separation effect of this sedimentation basin in existing technique
Time length bad, that sludge settling expends, is easily accessible simultaneous oxygen even anaerobic state, causes activated sludge strain poor activity；It is special
It is not that the poorer sludge settling of sludge activity is poorer, it is difficult to separate.
The content of the invention
In place of overcoming above shortcomings in the prior art, it is an object of the invention to provide a kind of activity bacterium mud
Screening washer.
The present invention is achieved through the following technical solutions：A kind of activity bacterium mud screening washer, include the reaction chamber of box-shaped body, it is described
Bottom in reaction chamber is provided with lambdoid swash plate base and the sludge parallel with the inclined-plane of herringbone swash plate base water inlet row
Mud mouth, the bottom surface of herringbone swash plate base and the bottom of reaction chamber are equal in magnitude, and the top in reaction chamber is provided with the production mouth of a river, described
Both sides in reaction chamber are sequentially provided with the one-level being obliquely installed and skim gas plate and two level slash gas plate from lower to upper, are gone back on the reaction chamber
Provided with one-level exhaust outlet and secondary exhaust, one-level exhaust outlet is arranged on one-level and skims gas plate and reaction chamber inside outer wall junction,
Secondary exhaust is arranged on two level and skims gas plate and reaction chamber inside outer wall junction.
Preferably, two-stage of the present invention skims gas plate in inside, downwardly-sloped shape and reaction chamber inside outer wall junction
Into angle.
Preferably, angle of the present invention is acute angle.
Preferably, the bottom surface of herringbone base of the present invention and the bottom of reaction chamber are equal in magnitude.
The present invention compared with prior art, has advantages below and beneficial effect：Due to living provided with above structure, the present invention
Property bacterium mud screening washer the water outlet of activated sludge aeration reaction tank band mud concentration it is low, active poor, the sludge of the activated sludge of discharge
Easily separated with sewage, it is few to discharge water to the activated sludge that sedimentation in secondary sedimentation tank is got off, and increase activated sludge aeration reaction tank sludge is dense
Degree, good sewage processing effect.
