Abstract
The utility model relates to a sewage treatment filtering tank based on a grid wall material-bearing water-distribution method. In the utility model, material-bearing water-distribution grid walls (3) are poured at intervals by utilizing concrete at the bottom part of a filtering tank, and a back-flushing vapor-water pipeline (4) is arranged between the every two adjacent grid walls; a filtering material bearing plate (2) arranged horizontally at the upper part of the grid walls (3) is supported by the grid walls; and filtering materials are uniformly paved on the filtering material bearing plate (2) in a stacking manner. In the utility model, the material-bearing water-distribution grid walls with different widths and distances are designed according to the water conservation load, the reasonable configuration of gas, water and solid is realized by utilizing the material-bearing water-distribution grid walls, so that the gas, the water and the solid are separated by the grid walls, so as to realize uniform air inflation, unblocked flow and stable solid phase configuration; and the sewage treatment filtering tank can effectively prevent blind angle for the filtering materials, layering and disordering of the filtering materials owning to partial strong flushing of the gas and the water, falling off of surface biomembranes, so as to achieve the purposes of reducing power loss and the running away of the filtering materials when a sewage plant is operated.
Description
Technical field
The present invention relates to the improvement of sewage disposal filter tank structure.
Background technology
Gas, moisture are joined uniformity coefficient wastewater treatment efficiency are played an important role in the sewage disposal filter tank.Especially backwash, moisture are joined evenly, can prevent effectively that filtrate from producing the dead angle, prevent that the surface biological film comes off owing to gas, water section washed and cause filtrate layering disorder by force.Power loss and filtrate when reasonably the support structure also can reduce the Sewage Plant operation simultaneously run off.
Summary of the invention
The invention provides a kind of lattice wall bearing material water distribution structure that can the support filtrate in the sewage disposal filter tank, its purpose is intended to prevent that filtrate from producing the dead angle, prevent owing to gas, water section washed and cause filtrate layering disorder by force, the surface biological film comes off, the purpose that power loss and filtrate run off when reaching the operation of minimizing Sewage Plant.
In order to achieve the above object, the invention provides a kind of sewage disposal filter tank, be positioned at filter tank bottom and utilize concrete to pour into a mould bearing material water distribution lattice wall at interval, and make and be provided with a backwash steam-water pipe between adjacent two described lattice walls based on lattice wall bearing material water distribution method; The filtrate supporting plate that the top that is positioned at described lattice wall utilizes lattice wall support level to be provided with is positioned at that the conforming layer lay-up is provided with filtrate on the described filtrate supporting plate.
The present invention is based on the sewage disposal filter tank of lattice wall bearing material water distribution method, main spacing, thickness and the paving mode that is the lattice wall, the layout of backwash system dative wall improved.And lattice wall bearing material water distribution method is to be used for support filtrate in the reactor of V-type filter tank in the sewage disposal, a kind of support structure of mean allocation backwash water, gas.According to the bearing material water distribution lattice wall of water conservancy load design different in width and spacing, utilize bearing material water distribution lattice wall to play the reasonable disposition of gas, water, solid three-phase, make and bring about the desired sensation, liquid, solid three phase objects split with the lattice wall, reach inflation evenly, current are unimpeded, the effect that the solid phase configuration is firm.Can prevent effectively that filtrate from producing the dead angle, prevent that the surface biological film comes off owing to gas, water section washed and cause filtrate layering disorder by force, the purpose that power loss and filtrate run off when reaching the operation of minimizing Sewage Plant.
Description of drawings
Fig. 1 is the top plan view structural representation in sewage disposal of the present invention filter tank;
Fig. 2 be among Fig. 1 A-A to the sectional structure schematic diagram.
The specific embodiment
As depicted in figs. 1 and 2, at the bottom of the pond, sewage disposal filter tank of building up, complete the backwash pipeline, according to predefined spacing and width with concrete cast bearing material water distribution lattice wall 3, treat that strength of wall body reaches requirement after, lay filtrate supporting plate 2, the spacing of filtrate supporting plate 2 will be laid in strict accordance with requiring.At last filtrate 1 in layer is layered on the filtrate supporting plate 2, the water flowing operation gets final product.Among Fig. 2, be provided with a backwash steam-water pipe 4 between adjacent two lattice walls.
Under a kind of optimal way, according to the design in V-type filter tank load, at the bottom of the pond along wide to the concrete bearing material water distribution lattice wall of making the constant spacing fixed thickness.If the backwash water yield is 500m
3/ h, tolerance is 100m
3/ s, supporting layer particle diameter of filter medium 35mm, fine filtering material be 3mm then, lattice wall spacing is set at 250mm, lattice wall thickness degree is 120mm.Lay concrete filtrate supporting plate on the lattice wall, adjacent supporting plate gap is 5mm.
The above; only be the preferable specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
