A kind of vertical container-type intermittent activated sludge process waste disposal plant
Technical field
The present invention relates to a kind of waste disposal plant, be specifically related to a kind of vertical container-type intermittent activated sludge process waste disposal plant.
Background technology
Common sewage disposal device generally adopts skeleton construction in-site installation to build, and applicable situation is the sewage disposal point that treatment sewage site is fixed, sewage load is large.For the occasion that sewage site is unfixing or sewage load is little, adopt the mode of on-the-spot civil engineering to build, have the deficiencies such as laid down cost is high, long in time limit.For this reason, the container type sewage treatment equipment of multiple integration is had in prior art, such as, Authorization Notice No. is the utility model patent disclosed " a kind of container type sewage treatment equipment " of CN204325092U, Authorization Notice No. is the utility model patent disclosed a kind of " container-type MBR integrated equipment for sewage treatment " of CN203256092U, Authorization Notice No. is utility model patent disclosed " a kind of movable integrated MBR sewage disposal device " of CN202156971U etc.Each processing unit is arranged in freight container by these integrated sewage treating apparatus, has transport and easy for installation, the advantage such as floor space is few, can move flexibly.
Existing integrated container formula sewage disposal device is and builds up rear laterally arrangement, and namely ground is pasted on the long limit of freight container; And standard container short height 2.3 meters, if for intermittent activated sludge process (SBR) sewage disposal, constrain available depth (desirable effective submersion depth is 4 ~ 5 meters), when there is biochemical aeration not high, the sludge settling district of oxygen utilization rate and clear water zone distance too short cause to occur during supernatant liquor water outlet that mud mixed flow affect effluent quality, mud collection area is difficult to arrange funnel, supernatant water outlet because of the elevation of water surface deficiency difficult problem such as power pumping possibly, the therefore mostly technique such as application MBR.
Often there is treatment sewage to have the little feature of intermittent water and water outlet, the water yield in reality, such as, throw aside the cleaning sullage produced in plastic cleaning and sorting process, the ground sewage etc. cleaning colony house in the process at the food residual end of aquaculture and livestock culture; Facts have proved the adjustment of existing collection, aeration for many years and be deposited in one, realize in same device water inlet, reaction, precipitation, draining and idle function intermittent activated sludge process (SBR) sewage disposal technology have that flow process is simple, working cost is low, dephosphorization denitrogenation, good effect of separating solid from liquid, stable effluent quality, effectively prevent sludge bulking and anti impulsion load, operation runs the advantages such as simple, and effect comparatively MRB is good, is very suitable for above-mentioned sewage disposal occasion.Therefore develop a kind of container-type, can make in factory, convenient transport has important practical significance with the SBR device installed.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of vertical container-type intermittent activated sludge process waste disposal plant is provided, this waste disposal plant adopts the vertical container main body arranged, for twenty equivalent unit, its overall dimensions are about 6.0 × 2.3 × 2.3 meters, virtual height can reach 4 ~ 5 meters, meets the working conditions of SBR completely; And have be convenient to transport, easy for installation, floor space is few, can move flexibly tear open, structure is simple, is convenient to the advantages such as assembling and maintenance.
