Description
Technical field
The present invention relates to technical field of water treatment, be specifically related to a kind of complex biological filter of hyperbolic configuration.
Background technology
Biological filter is mainly used in sewage disposal, is the one of biological filter.Traditional biological filter tank generally adopts the columnar structures of relative closure, and the ventilation process of this type of biological filter, air passes through filter bed from bottom to top or from top to bottom.Find by literature search, the patent No. is that the Chinese utility model patent of ZL02215898.7 discloses a kind of Integral biological filtering pool, comprises biological filter, settling tank, the gap ring groove of settling tank, mud discharging mouth, water port, settling tank there is column, be biological filter above column, have filter opening bottom biological filter, between biological filter and settling tank, have Stilt layer, the advantage of this utility model is that floor space is little, runs the lifting not needing waterpower.Although this patented technology improves to some extent on settling tank, but adopt or common biological filter, traditional biological filter tank is difficult to rely on natural ventilation to meet the demand of microorganism to oxygen, cause the stink that anoxic or anaerobic digestion produce, therefore, usual needs, by power ventilation effect, can ensure that air can flow uniformly through fillers all in filter bed, microbiological deterioration is normally played.
Traditional biological filter tank filler adopts the mode successively superposed to be placed in bed of packings, if water inlet pre-treatment is improper, the contained material such as plastics, cloth waste sheet, fiber is easy to the blocking causing filler, therefore, traditional biological filter tank is higher to water inlet pre-processing requirements, only use coarse rack inadequate, also should have the fine fack being less than 1mm or preliminary sedimentation tank.The slight latch up phenomenon of packing layer can be solved by back flushing, as blocking is comparatively serious, then needs manually to draw and digs, cleans and even change filler.The blocking of filtrate bed is biological filter recurrent problem in engineer applied, and the mode that traditional biological filter tank filler successively superposes considerably increases filler back flushing, the workload of replacing and operation easier.
Traditional biological filter tank operational mode is simple, normally carries out designing according to the specific influent quality water yield, needs reserved enough amplification quantity for influent quality water yield larger fluctuation.The microorganism being attached to filler presents the trend reduced gradually along liquid flow direction, limit the further raising of biological filter processing power.The simultaneously apposition growth pattern of fluid flow pattern and microorganism in traditional biological filter tank, accumulation along the biology growth bottom filter bed and biomass is reduced, the corresponding minimizing of biofilm thickness, thus cause filter bed processing power to be successively decreased in bottom, this just inhibits the further raising of biological filter processing power, particularly for ammonia nitrogen in high density water inlet, organic concentration lower bottom filter bed is unfavorable for the generation of denitrification process.
Summary of the invention
In order to overcome the shortcoming and defect existed in prior art, the object of the present invention is to provide a kind of complex biological filter of hyperbolic configuration, this complex biological filter adopts hyperbolic line tower body, be beneficial to nature forced ventilation, maximum ventilation can be reached, under the condition not increasing energy consumption, rely on natural ventilation can to meet in filter bed microorganism to the demand of oxygen.
Object of the present invention is achieved through the following technical solutions: a kind of complex biological filter of hyperbolic configuration, comprise open-topped tower body, the filter bed be fixed in tower body, be fixed on the water distributor above filter bed, the water inlet pipe be communicated with water distributor and the water outlet be opened in bottom tower body and multiple ventilation opening, the bus of the vertical cutting plane of tower body is hyperbola.
