Abstract
The utility model provides an aeration biological filter with a hollow porous fiber filler and a flow baffle plate. A water inlet is formed on one side of an aeration biological filter, a water outlet is formed on the other side of the aeration biological filter, a plurality of flow baffle plates (i) are fixedly connected to the bottom end of the aeration biological filter respectively, the height of the flow baffle plates (i) is 4/5 of that of the wall of the aeration biological filter, flow baffle plates (ii) are fixedly connected to the top of the aeration biological filter respectively and arranged between the flow baffle plates (i), the height of the flow baffle plates (ii) is 4/5 of that of the wall of the aeration biological filter, and a filler is arranged inside the aeration biological filter. The utility model has the technical benefit of increasing the sludge concentration in the unit space. The aeration biological filter achieves the effect of bubble-free aeration, greatly improves the mass transfer efficiency of oxygen, and can handle high-concentration organic wasted water. Besides, the filtering medium is kept in a fluid state in water to prevent blockage and reduce the back washing frequency. The aeration biological filter saves energy and reduces the floor area.
Description
Technical field
The utility model relates to a kind of BAF, relates in particular to a kind of hollow multiporous fiber filler baffling BAF.
Background technology
BAF is to integrate bio-oxidation and hold back suspended solids, saved follow-up secondary sedimentation basins, treatment process is simplified, in addition, biological aerated filter process organism volumetric loading height, hydraulic load is big, hydraulic detention time is short, required initial cost is few, energy consumption and running cost is low, this technology effluent quality height simultaneously.Filtrate is the key component of BAF, and the effect of BAF is had direct influence, also has influence on the structure formation and the cost of BAF simultaneously.Because make processing and price reasons, the contact filler of domestic present employing mainly contains glass reinforced plastic or plastic honeycomb filler, three-dimensional wavy filler, soft cellulose filler, semi soft packing and irregular particulate filter (sand, rubble, slag, coke, hard coal) etc.Glass reinforced plastic or plastic filler smooth surface, the microbial film poor adhesive force, easily aging, and often be easy to generate the obstruction of filler in various degree in actual use; Flow-shape in the soft-filler is undesirable, is easily bonded together by microbial film, produces the balling phenomenon, and its effective surface area is greatly reduced, and then produces the anaerobism phenomenon in the inside of balling, influences treatment effect.Irregular particulate filler flow resistance is big, is easy to cause the filter tank obstruction.China has also carried out little Pollution Study of using sheet haydite processing water source in recent years, the sheet haydite belongs to irregular particulate filler, although carrier surface forming biofilm property is good, but have that flow resistance is big, porosity is little, easy obstruction, intensity difference, easy broken, not anti-defective such as wash away, limit it and only can be applied to little pollution processing of source water, and be not suitable for sewage disposal.There is certain defective just because of these traditional contact fillers, limited the application of BAF in wastewater treatment in China, therefore select for use a kind of good filter tank filtrate very crucial.
Summary of the invention
The purpose of this utility model is to provide a kind of hollow multiporous fiber filler baffling BAF, adopting the hollow multiporous fiber is filler, carry out aeration in tubular fibre inside, and traverse baffle is set in the filter tank, overcome the shortcoming that aerating biological filter pool filler easily stops up, needs frequent back flushing, improve oxygen mass transfer efficient, increase current journey and treatment time of water.This BAF is simple in structure, satisfy microorganism to the oxygen demand in the conserve space and the energy, can efficiently remove simultaneously COD and nitrogen, improve effluent quality.
The utility model is achieved like this, it comprises BAF, water-in, water outlet, traverse baffle ⅰ, traverse baffle ⅱ, filler, a side that it is characterized in that BAF has water-in, opposite side has water outlet, the bottom of BAF is fixed with some traverse baffle ⅰ respectively, the height of traverse baffle ⅰ be BAF the pool wall height 4/5, top in BAF between the traverse baffle ⅰ is fixed with traverse baffle ⅱ respectively, the height of traverse baffle ⅱ is 4/5 of a BAF pool wall height, is placed with filler in the BAF.
Technique effect of the present utility model is: current flow in mode up and down, increase current journey and treatment time of water, simultaneously perpendicular to hollow-fibre membrane, are beneficial to holding back of microorganism.In addition, the specific surface area of hollow-fibre membrane is big especially, has improved the sludge concentration in the unit space, and foamless oxygen-supplying is adopted in this invention, and the mass-transfer efficiency of oxygen also improves greatly, can handle high concentrated organic wastewater.In addition, it is flow-like that filtrate is in water, is difficult for stopping up, and can reduce the back flushing frequency, and save energy reduces floor space.

Embodiment
As shown in Figure 1 and Figure 2, the utility model is achieved like this, one side of BAF 1 has water-in 2, opposite side has water outlet 3, the bottom of BAF 1 is fixed with some traverse baffle ⅰ 4 respectively, the height of traverse baffle ⅰ 4 be BAF 1 the pool wall height 4/5, top in BAF 1 between the traverse baffle ⅰ 4 is fixed with traverse baffle ⅱ 5 respectively, the height of traverse baffle ⅱ 5 is 4/5 of BAF 1 a pool wall height, is placed with filler 6 in the BAF 1.During the reactor operation, sewage is flowed into by water-in 2, air or pure oxygen enter the inner chamber of tubular fibre by blast main, by film diffusion oxygen supply, sewage is by traverse baffle ⅰ 4 water distribution uniformities, and current flow through hydrophobicity hollow microporous fibers filler beam 6 between traverse baffle with certain angle, and microorganic adhesion is on the hollow-fibre membrane surface, after oxygen diffused through film, the microorganism that directly is attached at the film outer wall utilized.It is flow-like that filtrate is in water, is difficult for stopping up.In the whole service process, the whole one-tenth of current plug-flow state flows through hollow-fibre membrane at a certain angle, is beneficial to holding back of microorganism.Simultaneously, the microorganism of being held back by hollow-fibre membrane can obtain competent oxygen owing to directly contact with hollow-fibre membrane.In addition, the required nutritive substance of microorganism growth also constantly obtains supply because of entering of sewage.After the certain hour operation, can suitably carry out back flushing to filtrate.
