Abstract
The utility model discloses an air-water distribution system capable of avoiding blocking and hardening. A plurality of filter bricks are mutually buckled and laid at the bottom of a filter tank to form the air-water distribution system, high-strength concrete is poured into the filter bricks, the outside of each filter brick is wrapped with hollow nanometer materials, a void ranging from 5mm to 8mm needs to be reserved between the bricks and used for distributing water and air, the void ratio ranges from 3% to 6%, so that the water and the air are uniformly distributed in the single-lattice filter tank. The air-water distribution system is used for a filter system of the filter tank, and has the advantages of simple structure, low cost, high pressure resistance, long service life and the like.
Description
Technical field
The utility model relates to the environmental protection field, particularly a kind of air water distribution system of stopping up, exempting to harden of exempting from.
Background technology
Filtration is the indispensable link of sewage disposal; Traditional sand filter is used to the highly stable effect that feeds water; But be used for there are problems aspect the advanced treatment of wastewater, for example: harden in the filtrate top layer, the inner caking of filtrate and cause the sand filter problems such as being prone to obstruction that is in operation.
Trace it to its cause and mainly be:
One, the water quality characteristic of sewage and feedwater are very different;
Two, remove the difference of the degree of suspension;
Three, traditional filter block hardens easily.
For these reasons, be badly in need of a kind of new technical scheme and solve above problem.
The utility model content
To the above problem of mentioning; The purpose of the utility model is: propose a kind of air water distribution system of stopping up, exempting to harden of exempting from; Can air hose and filtrate be carried out effective physical isolation, and reach the air water uniform distribution, 100% backwash effect and the functional requirement of exempting to stop up.
The utility model solves the technical scheme that its technical problem adopted:
A kind of air water distribution system of stopping up, exempting to harden of exempting from; Be laid on the bottom, filter tank and form by some inner perfusion strong concretes, the outside mutual hasp of filter block that forms by the hollow nano-material parcel; The space that should keep 5mm-8mm between filter block and the filter block; Be used for water and air distributing, voidage is 3%-6%, realizes the uniform water distribution distribution in single lattice filter tank thereby be implemented in.
Said filter block adopts the cellular plane of hexagon, and filter block both sides some hasps that convex to form that are crisscross arranged, and makes filter block can firmly connect each other.
Said filter block bottom surface left-right symmetric is distributed with some support columns to lower convexity, thus in be formed centrally a tracheae groove, tracheae can pass from the tracheae groove of filter block bottom surface, thereby has avoided tracheae to be exposed to the clogging that when outside cause easily effectively.
The beneficial effect of the utility model is: adopt the utility model to possess following advantage:
1, this filter block can effectively lower the effective depth in filter tank, makes filter tank construction cost low (low cost), can reduce investment outlay significantly, and operational management is convenient, operating cost low (low energy consumption);
2, this filter block compression strength is high, and operational effect is stable, and anti-shock loading strong (exempting to stop up) can effectively move more than 30 years;
3, the configuration design of this filter block is reasonable, and is flexible for installation, is suitable for various floor plan, and uniformity of water distribution is good.
Description of drawings
Fig. 1 is the utility model floor plan sketch map;
Fig. 2 is the filtration sketch map of the utility model;
Fig. 3 is the backwash sketch map of the utility model.
Wherein, 1-air water distribution system, the 2-quartz sand filter media, the 3-cobble, the 4-tracheae, 5-sewage cover plate, canal is collected in the 6-water outlet.
The specific embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.
Accompanying drawing 1 is a kind of floor plan sketch map of air water distribution system of exempting to stop up, exempt to harden, and by knowing among the figure: native system is laid on the bottom, filter tank and is formed by some inner perfusion strong concretes, the outside mutual hasp of filter block that is formed by the hollow nano-material parcel;
Should keep the space of 5mm-8mm between filter block and the filter block, be used for water and air distributing, voidage is 3%-6%, realizes the uniform water distribution distribution in single lattice filter tank thereby be implemented in.
Filter block adopts the cellular plane of hexagon, and filter block both sides some hasps that convex to form that are crisscross arranged, and makes filter block can firmly connect each other.
Said filter block bottom surface left-right symmetric is distributed with some support columns to lower convexity, thus in be formed centrally a tracheae groove, tracheae can pass from the tracheae groove of filter block bottom surface, thereby has avoided tracheae to be exposed to the clogging that when outside cause easily effectively.
Tell about down the filtration course of work in the filter tank of adopting the utility model below in conjunction with accompanying drawing 2:
Sewage is injected by the top, filter tank, after quartz sand filter media 2, cobble 3 filter, arrives air water distribution system 1; The gap of water after the filtration between filter block; Flow into uniformly, collect canal 6 through the sewage cover plate 5 inflow water outlets of filter block below then, thereby flow to clear water reserviors.
Tell about the backwash course of work in the filter tank of adopting the utility model below in conjunction with accompanying drawing 3:
In water outlet collection canal 6, inject clear water; Clear water arrives the air water distribution system through sewage cover plate 5, at this moment, and booster air pump; The tracheae 4 that below filter block, runs through oppositely dashes the filter course (cobble 2, English sand filtering material 2) to the filter tank with clear water, thereby accomplishes the process of backwash.
The above-described preferred embodiment of utilizing specifies the utility model, and the scope of unrestricted the utility model.Those skilled in the art can be through after reading the utility model; Make trickle change and adjustment; For example: the spacing in space between the adjustment filter block; Adjustment voidage and simple shape that changes the filter block planar structure or the like, the main idea of the utility model of will can yet be regarded as belongs to, and does not also break away from the spirit and the scope of the utility model.
Claims (5)
1. exempt from the air water distribution system that stops up, exempt to harden for one kind; It is characterized in that; Be laid on the bottom, filter tank and form by some inner perfusion strong concretes, the outside mutual hasp of filter block that forms by the hollow nano-material parcel, leave spacing between filter block and the filter block, thereby form the space.
