Description
Technical field
The utility model belongs to field of environment engineering technology, relates to a kind of filter tank equipment, is specifically related to a kind of box-type BAF.
Background technology
At present, BAF (biological aerated filter), compared with conventional activated sludge process, has that organic loading is high, floor space is little, is 1/3 of conventional activated sludge process; Less investment, can not produce sludge bulking, oxygen transmission efficiency is high, effluent quality is good advantage, but that it requires water inlet SS is tighter, general requirement SS≤100mg/L, and preferably SS≤60mg/L, therefore need to carry out pre-treatment to water inlet.Meanwhile, its back flushing water yield, head loss are all larger.
The startup of BAF is identical with the Starting mode of general biomembrance process.Three kinds of modes of general employing abroad: 1. intermittently cultivate and also progressively increase flow velocity; 2. under design current velocity or increase gradually flow velocity and carry out cultured continuously; 3. with active sludge inoculation, steady-state operation.In three kinds of Starting mode, the Changing Pattern such as biomembranous growth velocity, distribution and the clearance to pollutent is different, but it is roughly the same to reach the required time of stable state.
Utility model content
In order to overcome defect of the prior art, the purpose of this utility model is to propose a kind of box-type BAF simple in structure.
The utility model is achieved by the following technical solution:
A kind of box-type BAF, comprises casing, described casing open top, and described box house lower end is provided with the first pipeline, arranges to be provided with and revolve mixed aerator on described the first pipeline, and described the first pipeline is connected with outside Aeration fan; In described space of revolving mixed aerator top, be laterally provided with the first support, described casing top cross is provided with the second support, between described the first support and the second support, is provided with vertical supports, and hollow ball filler is installed in described vertical supports.
Further, described the first support and the second support be arranged in parallel.
Further, described two adjacent width between centers of revolving between mixed aerator are 50cm.
Described hollow ball filler adopts acrylic plastering to make, and is spherical, is provided with reinforcing ring at spherical hollow ball filler middle part one along girth, and the above-below direction of reinforcing ring is respectively provided with 12 ball clacks, is radiation arranges along central shaft.
The utility model adopts immobilization technology, described zymin and variation bacterium are attached to the surface of described hollow ball filler, prevent the loss of zymin and variation bacterium, increased with filter tank in the contact area of sewage, described zymin and variation bacterium have been eliminated the stink that sewage produces, drive away pond fly, prevent secondary pollution; A large amount of lands used have been saved simultaneously.
Described variation bacterium and zymin belong to microorganism, after having sewage to enter in casing, in casing, add once make a variation bacterium and zymin, and these variation bacterium and zymin can be attached to the surface of hollow ball filler and breed metabolism, thereby play sewage purification effect.
Described form of revolving the cutting of mixed aerator employing multi-layer helical is carried out oxygenic aeration, in the time revolving mixed aerator described in air-flow enters, air-flow is first by entering lower floor's multilayer zig-zag aeration head after two road helical cut systems, carry out multilayer cutting, make bubble cut into microbubble, the utilization ratio that has so greatly improved oxygen, has aeration even, the feature that oxygen-transfer efficiency is high.
Further, described the first pipeline is UPVC pipe.Described UPVC pipe is existing installation, taking polyvinyl chloride (PVC) RESINS as carrier, in the time weakening the gravitation of molecular resin interchain, have temperature-sensitive accurately, timing melting, the good characteristic of the effective constituent of absorbing additives rapidly, simultaneously, adopt composite type heat stablizer, in being subject to catching in the process of high temperature and melting, suppressing, absorb at resin and the deviating from of hydrogenchloride, carry out two key addition reactions with polyene structure, active and unsettled chlorine atom in displacer molecule, thus catalyzed degradation and the oxygenolysis of resin under molten state effectively controlled.
Further, described bottom half is provided with sewage input tube; Described casing top is provided with output tube.
Compared with prior art, the superior effect of a kind of box-type BAF described in the utility model is: simple in structure, adopt immobilization technology, described zymin and variation bacterium are fixed on to the surface of described hollow ball filler, prevent the loss of zymin and variation bacterium, increased with filter tank in the contact area of sewage, soil removability is more than 95%; The utilization ratio of oxygen is revolved mixed aerator and has greatly been improved in employing, uses simple, with low cost.
