Description
Technical field
The utility model relates to technical field of waste water processing, especially a kind of Industrial Wastewater Treatment spiral-flow aeration biological filter.
Background technology
BAF is called for short BAF, it is a kind of New biological membrane method sewage treatment process growing up America and Europe the end of the eighties, obtain large development the beginning of the nineties, maximum-norm reaches hundreds of thousands of tpd, and this technique has the effect of removing SS, COD, BOD, nitrated, denitrogenation, dephosphorization, removal AOX objectionable impurities.There is volumetric loading, hydraulic load is large, hydraulic detention time is short, required initial cost is few, effluent quality good, operation energy consumption is low, working cost is few feature.But BAF need to regularly be carried out backwash, existing back washing device exists the backwash time long, the shortcoming that filler loss amount is large.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of Industrial Wastewater Treatment spiral-flow aeration biological filter, can solve the deficiencies in the prior art, is keeping, on the constant basis of backwash effect, having reduced the loss of backwash time and filler.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of Industrial Wastewater Treatment spiral-flow aeration biological filter, comprise pond body, pond body is provided with at least two screen plates, each screen plate below is provided with an aeration plate, screen plate comprises that two components are from the filter core of crossing arranging, the two ends up and down of crossing filter core are respectively arranged with train wheel bridge and lower plate, between train wheel bridge and lower plate, be provided with filter packing, on train wheel bridge, be fixed with hydraulically extensible bar, lower plate is arranged on hydraulically extensible bar, cross between filter core for two and be arranged with several eccentric cylinder backwash devices in parallel, the surface of eccentric cylinder backwash device is staggeredly equipped with water outlet and air outlet, eccentric cylinder backwash device is connected with rotating machine, between screen plate and pond body, being provided with spring formation elasticity is connected, on screen plate, be also provided with ultrasonic oscillator, the bottom of pond body is provided with water-in and backwash sewage draining exit, body top, pond is provided with water outlet and backwash sewage draining exit, on pond body sidewall between adjacent two screen plates, be provided with backwash sewage draining exit.
As preferably, on described aeration plate, be evenly distributed with several back taper production wells, in back taper production well, be provided with ball sealer.
As preferably, the exit diameter of described back taper production well is 5～10mm.
As preferably, the exit diameter of described back taper production well is 9mm.
The beneficial effect that adopts technique scheme to bring is: the utility model arranges multiple screen plates, each screen plate has the filter core of crossing of two separation, can, excessively adding different filter packings in filter core, realize the concentrated adsorption treatment to pollutents different in waste water.Hydraulically extensible bar can be adjusted the distance between train wheel bridge and lower plate, and then changes the stuffing pressure of filter packing.In the time filtering, improve stuffing pressure, improve filter effect, in the time of backwash, reduce stuffing pressure, the space between filter packing is strengthened, accelerate backwash speed.The air-flow that backwash is used and current go out ejection from eccentric cylinder backwash device, outwards carry out backwash from the inside of screen plate, compared with traditional backwash mode, backwash region have been divided into some layers, have reduced the loss of backwash region to backwash pressure.In the process of eccentric cylinder backwash device rotation, the centrifugal force producing drives screen plate to produce vibration, makes the bulk dirt in filter packing rely on centrifugal force to separate with filter packing.The high frequency concussion that ultrasonic oscillator produces can make small dirt particle depart from filter packing.Multiple backwash sewage draining exits are set on the body of pond, are convenient to the dirt that backwash goes out and discharge in time.Ball sealer in back taper production well can prevent that aeration plate is blocked, and after air-flow blows afloat ball sealer, air-flow forms annular flow and flows out, and improves the homogeneity that aeration plate is given vent to anger.The exit diameter of back taper production well is preferably 9mm, can ensure under the prerequisite of single hole treatment capacity, improves to the full extent the homogeneity of giving vent to anger.
