Abstract
The invention discloses a rotational-flow fluidized bed biological active carbon filter, relating to the fields of bioengineering and water treatment. The device is used for overcoming the shortcomings that a submerged biological filter is hard to wash backward and has small specific surface area, the power consumption of a quartz sand fluidized bed is high and the contact oxidation time is short. The rotational-flow fluidized bed biological active carbon filter is formed by combining the plastic biological active carbon with the suspension property and advantages of the suspended honeycomb filter material so as to realize fixed-time automatic backflushing and realize efficient and stable operation.
Description
A fluidized bed bio activated carbon filter, relates to biotechnology and water treatment field, and submerged bacteria filter is widely used at water treatment field, but exist back flushing more difficult, water consumption is large, aging microbial film and mud rinse not thorough, easily cause filtration resistance to increase, even stop up.Cause the unstable of operation, although quartz sand fluidized-bed specific surface area is large, start the defects such as power consumption is large, and water flow velocity is large, and the catalytic oxidation time is short.
This filter tank aims at the design of plastic biologic gac composite suspension honeycomb filtrate, and application air water upwelling moves, and utilizes the suspended state of the best proportion formation of filtrate, and water-gas distribution is equal, filtration resistance is little, rotational flow flushing, precipitation, the advantages such as central blow-down, has and rinse easily, and water consumption is few.
This filter tank application plastic biologic gac composite suspension honeycomb filtrate, specific surface area is large, and micropore is flourishing, there is activated carbon adsorptive capacity strong, and the fast biomass of membrane is large, is difficult for aging, having absorption and bio-contact oxidation dual function, is the biological filter that can bear high loading.
This filter tank will be designed with rectangle fillet, Aspect Ratio is that 2:1 floor space is few, underground or semi-underground construction cost is low, dark 3～4.5 meters of pond, at the bottom of pond, to central authorities' inclination 15～35, spend, form central blow-down type, with 1.2 meters of eminences of central blow-down mouth, if one deck stainless (steel) wire grid, mesh be take filtrate can not be by being degree, below Chi Ding, 25～30 centimeters are separately established one deck stainless (steel) wire grid, prevent that filtrate runs off, between two net grid, establish dividing plate one, dividing plate length is 1/2nd of pond length, passage is left at two ends, form ring-like eddy flow road, filtrate loading level is 75% of runner volume, water inlet and inflation system are distributed in lower net grid bottom, runner both sides are provided with road stream plate and the high pressure water jet pipe at multilayer 15 degree inclination angles, both sides water spraying direction is contrary, form relay and under the promotion of eddy flow, complete filtrate flushing process.Wash water is drawn with bottom from off line grid by high-pressure hydraulic pump, and the microbial film coming off and solid concentrate on central blow-down mouth through eddy flow carrying and discharge.This device can be realized timing automatic recoil, reaches steadily efficient operation.
