Abstract
The invention relates to a layered oxygen-supply aeration bacteria filter, which is capable of balancing oxygen-supply quantity of an aeration tank and comprises a filling layer, an aeration device, a water inlet and outlet device and a back flush device. The layered oxygen-supply aeration bacteria filter integrates the characteristics including layered aeration, high filtering velocity, suspended matter interception, regular back flush and the like, and is capable of performing secondary treatment and advanced treatment to waste water, performing the layered aeration, balancing the oxygen-supply quantity, enabling the oxygen supply of the filling layer in the aeration bacteria filter to be even and overcoming the defect that a conventional aeration bacteria filter is provided with an aeration pipeline only on a bottom layer so as to enable the oxygen supply for microorganism in an upper filling layer to be insufficient, and further pollution cleaning efficiency is influenced.
Description
Technical field
The invention belongs to novel water technology.Specifically; It is through the layered arrangement aerated conduit; Make the interior packing layer oxygen supply of BAF even; Overcoming conventional BAF only has bottom that aerated conduit is set to make in the filler of upper strata the mikrobe oxygen supply not enough, can effectively reduce filler simultaneously and latch up phenomenon occur, and then influence the defective of scrubbing efficient; In addition, can also make the microbial nutrition supply even.
Background technology
BAF (Biological Aerated Filter) is called for short BAF, is a kind of new bio embrane method sewage treatment process that grows up the America and Europe end of the eighties.This technology has the effect of removing SS, COD, BOD, nitrated, denitrogenation, dephosphorization, removal AOX (objectionable impurities); Be characterized in integrating bio-oxidation and hold back suspended solids; Saved post precipitation pond (second pond); With other secondary biochemical treatment compared with techniques, have that volumetric loading height, capacity of resisting impact load are strong, treatment effect, to carbon source pollutent and nitrogenous source pollutent have all that good removal effect, floor space are little, treatment scheme is simple, capital cost, running expense is saved and management simply, the level of automation advantages of higher.But in long-term practice, also find it owing to oxygen supply skewness in the packing layer that causes in the bottom anoxic, treatment effect is bad, can occur filler hole blockage problem simultaneously, has reduced the advantage of processing efficiency and this equipment greatly.
Summary of the invention
In order to overcome the defective that above-mentioned technology exists, the object of the present invention is to provide the BAF of a kind of ability balance aeration tank oxygen-supplying amount.This technology can also be carried out the balance oxygen supply to the aeration tank except having the advantage of ordinary biofilter, has improved the contradiction between mikrobe oxygen supply speed and aerobic speed, makes the microbial nutrition supply even; Also have an advantage be mud along the pond high uniform distribution, improved the adaptive faculty of aeration tank to waste water quality and impact load, effectively reduce the generation of filler latch up phenomenon.
Be to realize above-mentioned purpose, this technology layered arrangement aerating apparatus, the balance oxygen-supplying amount.It is cylindric that equipment integral is; Open two circular apertures near symmetry on the right cylinder of below; Two hole pars intermedias are separately one than aperture, lean on a little upward to fill up filtrate for spreading filter plate that one deck has an aperture above the coarse net trellis steelframe above again, having square beneficial tank from upper area and an aperture is arranged.Layering oxygen supply BAF comprises Inlet and outlet water device, packing layer, aerating apparatus, back-purge system four parts.All devices are all in circular tank; The Inlet and outlet water device is in the entire equipment bottom; By supporting plate itself and filler being separated, is packing layer on Inlet and outlet water device top, and aerating apparatus evenly is divided into and is distributed in the packing layer; Back-purge system and Inlet and outlet water device are positioned at same one deck, and the back flushing water-in is on Inlet and outlet water water-in opposite.Sewage gets into reactor drum by the water inlet pipe in the Inlet and outlet water device; Through the filler of the packing layer that separated by supporting layer, wherein supporting layer is on filter plate from bottom to top, and filter plate is supported by filter plate and holds; Aerator even laminating cloth on the layering aeration tube is placed in the filler; Sewage gets in the bodies of BAF pond through filler 4, finally gets into rising pipe through filler and pond body and the upper strata sewage that obtains certain biopurification by effluent weir, and finally through the rising pipe discharge.Aerator even laminating in the aerating apparatus on the layering aeration tube is distributed in the filler.The back flushing inlet pipe is between inlet pipe and water inlet pipe in back-purge system; Water purification is got into by water inlet pipe; Behind strainer head water distribution, gas, filler is carried out back flushing, the water after the last back flushing enters the back flushing braiding channel by the back flushing posticum and is discharged by the back flushing water shoot.In the operational process, air from bottom to top advanced filler mikrobe was carried out oxygen supply, and the aerating apparatus of layered arrangement makes the bubble uniform distribution.Waste water gets into the biological filter by water inlet pipe, is discharged by rising pipe through behind the filler from bottom to top.
Characteristics such as key of the present invention is to integrate layering aeration, high filtering velocity, holds back suspended substance, back flushing regularly can be carried out second-stage treatment and advanced treatment to waste water, can also layering aeration balance oxygen-supplying amounts, and make the microbial nutrition supply even.
