Abstract
The invention discloses a blocking-free sewage filtering tank. The blocking-free sewage filtering tank comprises a tank body, wherein the tank body is sequentially provided with a quartz sand filtering layer, a pebble bed, a filtering brick filtering layer and a clean water channel from top to bottom, wherein the bottom of the filtering brick filtering layer is also provided with a cover plate; a plurality of ventilation holes are uniformly distributed in the cover plate; the filtering brick filtering layer is built of a plurality of filtering bricks which are overlapped mutually. The blocking-free sewage filtering tank provided by the invention is simple in structure, is low in cost, has a good backflushing effect, and solves the blocking phenomenon thoroughly.
Description
Technical field
The present invention relates to technical field of sewage, particularly one exempts to stop up sewage water filtration pond.
Background technology
Along with our industrialization and the aggravation development of urbanization, in recent years between, the water contamination phenomenon of China becomes more and more serious, if these water sources after polluting are directly disposed in rivers, will directly cause serious pollution to rivers.Therefore, concentrated and be drained to sewage treatment plant by pipeline, just can be disposed to after treatment in rivers.
The filtration of sewage is link indispensable in sewage disposal process.Traditional sewage water filtration mode is to adopt the mode of sand filter to filter, and this method has highly stable filter effect.
But aspect the advanced treating for sewage, it exists again filtrate easily half to separate, thereby causes the problems such as sand pond obstruction.
Summary of the invention
For existing problem in above-mentioned prior art, the object of the invention is: propose a kind of sewage water filtration pond of exempting from obstruction, solved deficiency of the prior art.
The technical solution adopted for the present invention to solve the technical problems is:
One exempts to stop up sewage water filtration pond, comprises a pond body, and this pond body is provided with quartz sand filtration layer, boulder bed, filter block filter course and water-dilution channel from top to bottom successively.
Further, described filter block filter course bottom is also provided with a cover plate.
Further, on described cover plate, be evenly distributed with some passages.
Further, described filter block filter course is laid and is formed by the mutual hasp of some filter blocks.
Further, between described filter block, leave the space of 6mm-9mm.
Further, the voidage between described filter block is 7%-8%.
Further, described filter block adopts T-shaped filter block.
Further, the bottom of described water-dilution channel and horizontal direction inclination 10 degree angles.
The invention has the beneficial effects as follows: the present invention is simple in structure, with low cost, backwash effect is good, has thoroughly solved the phenomenon of stopping up.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-pond body, 2-quartz sand filtration layer, 3-boulder bed, 4-filter block filter course, 5-water-dilution channel, 6-cover plate.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, one exempts to stop up sewage water filtration pond, comprises a pond body 1, and this pond body is provided with quartz sand filtration layer 2, boulder bed 3, filter block filter course 4 and water-dilution channel 5 from top to bottom successively.
Further, filter block filter course 4 bottoms are also provided with a cover plate 6; On cover plate 6, be evenly distributed with some passages.
Further, filter block filter course 4 is laid and is formed by the mutual hasp of some filter blocks; Between filter block, leave the space of 6mm-9mm; Voidage between filter block is 7%-8%.
Further, filter block adopts T-shaped filter block.
Further, the bottom of water-dilution channel and horizontal direction inclination 10 degree angles.
Operation principle of the present invention is as follows: sewage flows through from quartz sand filtration layer 2, boulder bed 3 and filter block filter course 4 successively, finally flows out from water-dilution channel 5.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
