Description
Technical field
The utility model relates to a kind of waste disposal plant, a kind of biological respinse waste disposal plant that adopts air suction type.
Background technology
In the selection of existing sewage disposal mode, nearly all adopt two kinds in air blast Loss-on-drying gas and mechanical Loss-on-drying gas, some fillers that also add that have are immersed in and carry out bio-film colonization in the sewage.The structure of air blast Loss-on-drying gas includes blower fan, Ventilator Room, air-line system and Loss-on-drying gas head.Machinery Loss-on-drying gas mainly is surperficial Loss-on-drying gas.Use the gas blower air feed and mostly be in existing sewage disposal, its dynamic efficiency is generally 1.6--7.2kgO2/kwh.The power that they not only consume is bigger, and energy dissipation is serious; And system's occupation of land is many, the capital cost height, and using is not that easily accident conditions are many, the effect of sewage disposal is not ideal etc.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provide a kind of use recycle pump to realize the air suction type biological respinse waste disposal plant of the multiple function of ventilation, mixing and dissolved oxygen in the sewage disposal, it includes a hydroecium, hydroecium is provided with air intlet and sewage import, one of one upflow tube is terminated in the hydroecium, and the other end is connected to and two respectively being joined by diffuser tube and collapsible tube of being connected together mutually forms the high-speed mixing turbulator.
Respectively be connected to an aditus laryngis that constitutes by short tube between described upflow tube and high-speed mixing turbulator and the high-speed mixing turbulator.
The length of described upflow tube is L1/D1=10-12 with the ratio that is connected to the upflow tube inlet diameter on the hydroecium.The caliber of described trunnion is Dn/Ln=1 with the ratio of pipe range: 1.2.
High-speed mixing turbulator described in the utility model in addition has three and join by an aditus laryngis separately and form at least.Other geometric parameter of the present utility model is: D1/Dn=2.5--3, and L1/D1=10--12, D/Dn=2--2.2, L1/Dn=2.8--3, Dn/Ln=1: 1.2, V larynx=0.9--0.7m/s.
The utlity model has following technical characterstic: 1, atmospheric oxygen trans-utilization height, volumetric loading and sludge loading height, overflow device below dissolved oxygen keeps 3mg/1--5mg/l, enough dissolved oxygen contents guarantee aerobe treatment system heavy-duty service condition, biomass is big in the reactor, determined its load value inevitable high, the engineering operation result shows that volumetric loading reaches 18kgcOd/m3d.2, system takes up an area of fewly, and capital cost is low, and the system design compactness is rational in infrastructure, and hydraulic detention time is short in the reactor, and the volumetric loading height has reduced the volume of reactor.3, good effect of separating solid from liquid, surplus sludge volume is few, thereby has significantly reduced mud handling capacity.The major cause that surplus sludge volume is few has two, one, and strong air feed makes microbial metabolism speed fast, and the biological respinse that causes therefrom may strengthen endogenous consumption, and surplus sludge volume is few relatively; It is two because combined sewage is sheared by the high speed circulating fluid, and the granule of microorganism is constantly cut apart refinement, and an inner pore reduces, and its density is increased relatively, and total volume reduces.4, capacity of resisting impact load is strong, former water is mixed by the circulation of piece speed immediately, during the high concentration COD impact system, they are in fact diluted before entering reactor, after entering reactor, by rapid uniform mixing, the concentration of impacting liquid is lowered greatly again, thereby improve the anti-shock loading of reactor.In addition, strong oxygen supply Loss-on-drying gas also may reduce the some effects that impact causes after the metabolism of microorganism is accelerated.5, system operation is easy to be flexible, and treatment effect is secure, and system adopts quantity of circulating water, and mud quantity of reflux etc. can be regulated as required, is convenient to select best combined effect, adopts this plenum system to guarantee higher COD clearance.6, this system starts piece, convenient operation and management, and the envrionment conditions of adaptation is loose, in servicely seldom breaks down, and therefore, it has higher popularization and application values.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: the utility model includes a hydroecium 1, and this hydroecium 1 is provided with airport 2 and sewage import 3.Sewage import 3 is communicated in sewage (waste water) recirculating pump, and it is constantly imported sewage from this sewage import 3, simultaneously, under the effect of air negative pressure in hydroecium, constantly sucks from airport 2, carries out preliminary gas-vapor mix in hydroecium 1.One end of one upflow tube 4 stretches in hydroecium 1 and is fixed on the hydroecium 1, and upflow tube 4 is the contraction tubulose, its pipe range with stretch into nozzle diameter in the hydroecium 1 than L1/DL=10-12, another mouth of pipe of upflow tube 4 is connected to one section aditus laryngis 5 that is made of short tube.The caliber of this aditus laryngis 5 is Dn/Ln=1 with the ratio of pipe range: 1.2.And then aditus laryngis 5 back have the high-speed mixing turbulator 8 that is joined and formed by diffusion type pipe 6 and contraction-like pipe 7, gentle the flowing to into upflow tube 4 of current can thereunder form high-speed mixing turbulent shear district, enter high-speed mixing turbulator 8 immediately, the gas dispersion that sucks is become tiny bubble, make sewage form the combined sewage that is rich in dissolved oxygen.Described high-speed mixing turbulator 8 external phases are connected to three, all have aditus laryngis 5 to join between them.The combined sewage that is rich in dissolved oxygen is through several times high speed changed course blending dispersion, arrive in the sewage reactor, operation so moves in circles, sewage is by oxygenation repeatedly, bubble and microbial strains are constantly sheared refinement, and form fine and close tiny flocs unit, thereby organic oxygen requirement and organic oxygen-consumption are degraded, the general 3.0--3.5Kg02/kwh that only needs of its dynamic efficiency.The utility model is taken all factors into consideration from the raising of dissolved oxygen speed and the attenuating of energy consumption, and each geometric parameter of device is selected as follows: D1/Dn=2.5--3, L1/D1=10--12, D/Dn=2--2.2, L1/Dn=2.8--3, Dn/Ln=1: 1.2, V larynx=0.9--0.7m/s.
