Description
Technical field
The utility model belongs to the Industrial Wastewater Treatment device, particularly relates to 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 bio embrane method sewage treatment process that grows up the America and Europe end of the eighties, obtain large development the beginning of the nineties, maximum-norm reaches the hundreds of thousands of tpd, and this technology has the effect of removing SS, COD, BOD, nitrated, denitrogenation, dephosphorization, removal AOX objectionable impurities.BAF collection bio-oxidation and hold back the suspended solids one has been saved post precipitation pond (second pond), has volumetric loading, hydraulic load is big, hydraulic detention time is short, required initial cost is few, and effluent quality is good: operation energy consumption is low, the characteristics that working cost is few.But existing BAF exists intrinsic shortcoming, for example after using BAF for a long time, needs a large amount of clear water that BAF is carried out back flushing, has so just wasted the clear water resource greatly.Simultaneously, temperature is uncertain in the existing BAF, can not reach the reaction effect of expection sometimes under the situation of low temperature.
Summary of the invention
At the problems referred to above, the utility model provides a kind of Industrial Wastewater Treatment spiral-flow aeration biological filter.
Industrial Wastewater Treatment spiral-flow aeration of the present utility model biological filter, be to be constituted by reaction tank, agitator and light suspended filler, the reaction tank inner bottom part is provided with agitator and is connected with the variable-frequency motor of outside, be provided with two-layer baffle plate in the reaction tank of agitator top, be thick with through hole above it, between two-layer baffle plate, filled light suspended filler.
As further improvement of the utility model, the below of described light suspended filler, the sidewall of reaction tank are provided with more than one heating tube.
As further improvement of the utility model, the sidewall of light suspended filler below, reaction tank is provided with inlet valve and back flushing inlet valve; The sidewall of light suspended filler top, reaction tank is provided with flowing water Valve and back flushing flowing water Valve.
As further improvement of the utility model, the bottom of reaction tank is provided with vent valve.
The beneficial effect of Industrial Wastewater Treatment spiral-flow aeration of the present utility model biological filter is:
1, Industrial Wastewater Treatment spiral-flow aeration of the present utility model biological filter has less filtering layer resistance; Adopt the air water concurrent, the relative counteracting of flow velocity and gas velocity when having avoided the air water reverse flow and cause the waste of energy, in addition, particle diameter of filter medium is more even, increases the porosity of filtering layer greatly, the head loss when reducing the filter tank operation.
2, Industrial Wastewater Treatment spiral-flow aeration of the present utility model biological filter is selected the light suspended filler that price is low, performance is excellent for use; Filtrate has that wide material sources, filtrate specific surface area are big, the suitable microorganism growth in surface, low price, chemical stability are good; The filtrate specific surface area is big, is conducive to the mass transfer of oxygen, has improved oxygen-transfer efficiency greatly, and gas distribution can adopt the perforated pipe gas distribution to get final product, and saves construction investment.
3, the unique speed change agitator water washing form of Industrial Wastewater Treatment spiral-flow aeration biological filter employing of the present utility model; The recoil of traditional water, air water back washing all are difficult to prove effective, and unique pulse backwashing mode is adopted in this filter tank, does not need special backwash pump and gas blower, are a kind of back flushing forms of efficient, less energy-consumption.
4, inside, Industrial Wastewater Treatment spiral-flow aeration biological filter of the present utility model is provided with heating tube, and sewage is carried out certain heating, and makes the reaction conditions of sewage and filtrate more desirable, reaches the effect of accelerating speed of reaction.
