Abstract
The invention provides a filter material cutting device and a biological aerated filter provided with the same. The filter material cutting device comprises a frame of which the shape is fitted with that of the cross section of a body of the biological aerated filter, and a plurality of cutting strips which are fixedly connected to the inside of the frame. By the filter material cutting device, when a filter material is hardened, the cutting strips can effectively cut the hardened filter material to make the filter material recover to a loose state, so that the treatment effect of the filter cannot be influenced, and the operating efficiency of the filter is improved. The filter material cutting device is arranged in the biological aerated filter, so the washing period of a backwashing system can be shortened, the consumption of energy such as water, electricity and the like is reduced, and operating cost is also reduced under the conditions of a good treatment effect and high operating efficiency.
Description
Technical field
The present invention relates to a kind of for the filtrate cutting unit, and the BAF that this filtrate cutting unit is installed.
Background technology
As shown in Figure 1, traditional BAF that is used for sewage disposal comprises pond body and back-purge system.The bottom is equipped with filter plate 8 in the body of pond, and some filters are installed on the filter plate 8, is provided with filtrate 5 on filter plate 8.Sewage is processed by filtrate 5 in filter enters the pond body.In order to keep the processing power of BAF, need regularly with back-purge system filtrate to be carried out back flushing.Back-purge system comprises air purge system 6 and water wash system 7.
If enter that the sewage of BAF belongs to calcified material, phosphide content is high or the water quality such as viscosity ratio is larger, be easy to cause filtrate 5 to harden.Although can improve the situation that filtrate 5 hardens by regular backwash mode, but because the back flushing air purge system 6 in the back-purge system or the parameter designing of water wash system 7 have a threshold value, when surpassing backwash volume, even filtrate 5 is carried out back flushing, can not avoid the harden generation of phenomenon of filtrate 5 fully.In a single day filtrate 5 hardens, just can whole float, and has had a strong impact on treatment effect and the operational efficiency in filter tank.
Summary of the invention
The present invention will solve that filtrate easily hardens in the existing BAF, thereby makes BAF poor processing effect, technical problem that operational efficiency is low.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
Filtrate cutting unit of the present invention is used for BAF.The framework that matches comprising the pond body shape of cross section of shape and BAF and be fixedly connected on some cutting rods in the described framework.
Wherein, also comprise described framework is fixed to web member on the BAF pool wall.
Preferably, described web member is several expansion bolts.
Described framework is rectangular.
Crisscross being evenly arranged of described some cutting rods reticulates.
Wherein, the distance between two adjacent described cutting rods is 350-600mm.
Described cutting rod is reinforcing bar.
BAF of the present invention comprises the pond body with pool wall and the filtrate that is installed in bottom in the described pool wall.Wherein, filtrate cutting unit of the present invention is installed, this filtrate cutting unit is installed in the filtrate.
Preferably, described filtrate cutting unit is installed in the middle part of filtrate.
As shown from the above technical solution, advantage and the positively effect of filtrate cutting unit of the present invention and BAF are: because filtrate cutting unit of the present invention comprises framework and some cutting rods, therefore simple in structure, cost is low; Simultaneously, when filtrate hardened, cutting rod can cut the filtrate that hardens effectively, makes filtrate return to loose condition (of surface), can not affect the treatment effect in filter tank, was conducive to improve the operational efficiency in filter tank.
BAF of the present invention, because filtrate cutting unit of the present invention being installed in the filter tank, can reduce the flushing cycle of back-purge system, be conducive to conserve water, electric equal energy source consumption, in the situation that treatment effect is good, operational efficiency is high, also help reduction running cost.
By referring to the accompanying drawing description of a preferred embodiment, above-mentioned and other objects, features and advantages of the present invention will be more obvious.

Fig. 1 represents the structural representation of traditional BAF;
Fig. 2 represents filtrate cutting unit of the present invention is installed to vertical view after the BAF, for the clear structure that filtrate cutting unit of the present invention is shown, has removed the filtrate that is arranged on above the filtrate cutting unit;
Fig. 3 represents to be equipped with the side-view of the BAF of filtrate cutting unit of the present invention.
Embodiment
Describe specific embodiments of the invention in detail below in conjunction with accompanying drawing.Should be noted that the embodiments described herein only is used for illustrating, be not limited to the present invention.
As shown in Figures 2 and 3, filtrate cutting unit of the present invention is used for BAF.Comprise framework 2 and be fixedly connected on some cutting rods 3 in the framework 2.
BAF of the present invention comprises the pond body with pool wall 4 and the back-purge system that is comprised of air purge system 6 and water wash system 7.The bottom is equipped with filter plate 8 in the body of pond, is installed in some filters on the filter plate 8, is provided with filtrate 5 on filter plate 8.Filtrate cutting unit of the present invention is installed in the filter tank.The framework 2 usefulness expansion bolts 1 of filtrate cutting unit are fixed in filter tank pool wall 4 ponds, and the fixed position exceeds at the bottom of the pond approximately 1m of filter plate 8, namely roughly corresponding to filtrate 5 medium positions, certainly is not limited to this position, if interior at filtrate 5 all be feasible.Cutting rod 3 is welded on the framework 2, laterally with vertically respectively laying welding.Distance is 350-600mm between the cutting rod 3.
BAF of the present invention, the back-purge system function that has namely kept traditional filter tank, can regularly wash filtrate 5, in normal water quality situation, move, guaranteed that filtrate 5 is difficult for hardening, in the special water quality situation, move simultaneously, when filtrate hardens, when moving hardening the filtrate floating, particularly under the instant impact effect when back flushing begins, on the filtrate that hardens is violent, lower when mobile, namely by cutting rod 3 cuttings in the filtrate cutting unit, thereby make filtrate 5 return to loose condition (of surface), namely recovered the processing power to sewage, therefore the operational efficiency of BAF of the present invention is high.In addition, the filtrate cutting unit is installed in BAF, can be reduced the flushing cycle of back-purge system, be conducive to conserve water, electric equal energy source consumption, be conducive to reduce running cost.
Although described the present invention with reference to several exemplary embodiments, should be appreciated that used term is explanation and exemplary and nonrestrictive term.Because the present invention is implementation and do not break away from spirit or the essence of invention in a variety of forms, so be to be understood that, above-described embodiment is not limited to any aforesaid details, and should be in the spirit and scope that the claim of enclosing limits explain widely, therefore fall into whole variations in claim or its equivalent scope and remodeling and all should be the claim of enclosing and contain.
