Abstract
The utility model discloses an upward flowing aeration biological filter of soft filling materials, a filtering device thereof is provided with a bearing layer (1). The biological filter is characterized in that a tilting soft biological filling material layer (2) is arranged on the bearing layer (1). The soft biological filling material layer has the advantages of big surface area, high ability of removing the volume loading of organics, good biological adherence, changeable space, strong adaptability, low price, simple and easy assembly, convenient management and the like, and the filter is not easy to plug. The soft biological filling material layer which is obliquely arranged can cut the upward sewage flow, and enables the sewage to fully contact with biological film, thereby guaranteeing all the sewage to contact with the filling materials, and thereby all the sewage can be processed.
Description
Technical field:
The utility model relates to a kind of upward flow aeration in sewage treatment biological filter, especially a kind of BAF with soft-filler layer.
Background technology:
The filler that uses in the BAF is a lot, is that porosity is big for the requirement of filler, can adsorb more biomass, and density is suitable.At present BAF most of use mineral-type filtrate, organic class filtrate arranged, organic class filler is divided into hard filler and soft-filler again.Wherein there are the shortcomings such as homogeneity that weight is big, be difficult to control filtrate in the mineral-type filtrate.Though soft-filler can address the above problem, generally only can be used in the pulling flow type treatment tank, and be vertical the placement, be of limited application.
Summary of the invention:
The utility model is at the above-mentioned deficiency of prior art, provide a kind of light and handy, be easy to manage, the soft-filler upward flow BAF (biological aerated filter) of good sewage processing effect.
Technical solution of the present utility model is: a kind of soft-filler upward flow BAF (biological aerated filter), its filtration unit is provided with supporting layer, is provided with the soft biologic packing material layer of inclination on supporting layer.
The angle of inclination of described soft biologic packing material layer is in vertical direction with 15 to 30 degree.
Soft biologic packing material layer of the present utility model have surface-area big, remove organism volumetric loading height, advantages such as biological adhesiveness is good, the space is variable, be difficult for stopping up, adaptability is strong, low price, easily assembled, convenient management.And tilted-putted soft biologic packing material layer can cut effluent stream upwards, and sewage is fully contacted with microbial film, can guarantee that so all sewage can both touch filler, makes all sewage can both obtain handling.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of soft-filler upward flow BAF (biological aerated filter), its filtration unit is provided with supporting layer 1, is provided with the soft biologic packing material layer 2 of inclination on supporting layer 1, and the angle of inclination of soft biologic packing material layer 2 is in vertical direction with 15 to 30 degree.
The soft-filler layer is fixed four angles and certain angle that tilts in Up-flow Biological Aerated Filter.Can cut effluent stream upwards, sewage is fully contacted with microbial film, can guarantee that so all sewage can both touch filler, make all sewage can both obtain handling.
Claims (2)
1, a kind of soft-filler upward flow BAF (biological aerated filter), its filtration unit are provided with supporting layer (1), it is characterized in that: the soft biologic packing material layer (2) that is provided with inclination on supporting layer (1).
2, soft-filler upward flow BAF (biological aerated filter) according to claim 1 is characterized in that: the angle of inclination of described soft biologic packing material layer (2) is for spending in vertical direction with 15 to 30.
