Sealing portion can be covered by soil.
In addition, as shown in fig. 1, bottom 13b has the 13c of hole portion and 13d at each side end place. Pump 15a and 15b are arranged on respectively in the 13c of hole portion and 13d. Pump 15a and 15b can be described after a while.
The pipes for sewage being directed into xoncrete structure 13 inside through the 13a of wall portion the water inlet pipe 17 that extends up to xoncrete structure 13 inside. Term " sewage " comprises various sewage, comprises the initial rainwater that comprises pollutant, sanitary sewage and waste water.
This pretreatment portion is made up of the first handling part 21 and the second handling part 29, and the first handling part 21 and the second handling part 29 are separated by barrier walls 25. This pretreatment portion has preliminary dimension or larger sized pollutant for screening out in the pollutant that is blended in sewage.
For this purpose, coarse net sieve 23 is equipped with in the inside of the first handling part 21. Coarse net sieve 23 is the basket-like member with inner idle space, and it screens out the various alloys of introducing by water inlet pipe 17 with sewage. Various alloys comprise stub, fallen leaves, rubbish etc.
Coarse net sieve 23 inner spaces that are arranged on are towards the unlimited Vertical Channel of the 13c of hole portion, and the inner wall surface of this coarse net sieve 23 and the first handling part is spaced apart. Thus, even also not cleaned and while making water be excreted to outside smoothly due to the pollutant stopping up when coarse net sieve 23, flow out in the gap that sewage also can sieve between 23 outer surface and this inner wall surface by coarse net. Thus, can not occur by the backflow phenomenon of water inlet pipe 17.
Below barrier walls 25, flow downward and enter the second handling part 29 through the water of this coarse net sieve.

The internal diameter of guiding diffuser 37 increases towards the upper end of guiding diffuser 37. Thus, the flow velocity of the sewage of introducing by guiding diffuser 37 reduces towards upper end, makes effluent stream still in upper end, and prepares to be filtered by filter module part 39.
The support plate 49 that is fixed to guiding diffuser 37 upper ends is supporting members of along continuous straight runs supporting filter device module section 39. The lower end of support plate 49 blocking filter module sections 39, makes to flow and the sewage that passes can not flow out by the lower end of filter module part 39 along the radial direction of filter module part 39.
Comprise that the outside area that is positioned at the inner area in guiding diffuser 37 and the space of support plate 49 tops and the space of the second fine mesh filter 45 inside and is different from this inner area is respectively contraminated zone and clean pool. Contraminated zone is to store the sewage not yet removed of pollutant and the region of pollutant, and outside area is the region of storing cleaning water, i.e. treated water.
Support plate 49 is equipped with bleed valve (in Fig. 4 57) and has two porus excretoriuses (49a in Fig. 4). Porus excretorius 49a is opened and closed by the switching device illustrating after a while. Porus excretorius 49a opens wide during backwash filter module section 39. Illustrate in greater detail porus excretorius 49a and bleed valve 57 with reference to accompanying drawing 4 after a while.
Filter module part 39 is fixed to the upper surface of support plate 49. Filter module part 39 allows the sewage upwards flowing by guiding diffuser 37 radially to pass along it, purifies waste water thus.
Filter module part 39 comprise have predetermined thickness cylindrical shape curtain formula filter portion 41, be arranged on the inner and cylindrical shape mesh filters 47 working as framework of this curtain formula filter portion 41, the second fine mesh filter 45 that is arranged on the first fine mesh filter 43 of these curtain formula filter portion 41 outsides and is arranged on the first fine mesh filter 43 outsides.
Mesh filters 47, curtain formula filter portion 41 and the first fine mesh filter 43 and the second fine mesh filter 45 have respectively different diameters, but their center is identical. That is to say, in the time seeing from top, they are coaxially arranged. The first fine mesh filter 43 is less than the size of curtain formula filter portion 41 along the size in short transverse, and the second fine mesh filter 45 is less than the size of the first fine mesh filter 43 along the size in short transverse.
Curtain formula filter portion 41, the first fine mesh filter 43 structure different with the height of the second fine mesh filter 45 are designed to prevent filter blocks. That is to say, in the time that abnormal the obstruction occurs filter 41,43 and 45, the water overflowing from curtain formula filter portion 41 can flow through the first fine mesh filter 43 and then flow through the second fine mesh filter 45, thereby is excreted.
Fiber medium is arranged in curtain formula filter portion 41. Fiber medium is made up of fiber, and in order to filter the pollutant in sewage. Fiber medium is made up of multiple fibrages, and multiple fibrages comprise for example spaced and high-density fiber medium, intermediate density fiber medium and low-density fibre medium from the most inboard to outermost arranged in sequence. The gross thickness of curtain formula filter portion 41 is larger, and filter efficiency is higher.
The first fine mesh filter 43 is the filter members that have than curtain formula filter portion 41 less mesh openings. The first fine mesh filter 43 filters out passes the pollutant of curtain formula filter portion 41 and allows water to pass.

The second fine mesh filter 45 has than the thinner mesh openings of the first fine mesh filter 43, and finally filters out pollutant. The water being filtered out by the second fine mesh filter 45 is the substandard water of contained pollutant levels. Processed water is full of the main treatment region 67 in filter module portion 139 outsides, then flows through excretion weir plate 53, to be excreted to outside by tapping pipe 19.
Although sewage is processed by above-mentioned processing procedure, if flowed into because rain stops no longer including sewage, the treated water of so main treatment region 67 interior storages can not be flow through excretion weir plate 53. That is to say, processed hydropexis is in main treatment region 67.
Be arranged on the pump (15b in Fig. 4) in the 13d of hole portion by operation, in main treatment region 67 store clean water by clean water outflow manage 16a discharge xoncrete structure 13. The process of being discharged water by pump 15b is continued until that bottom 13b exposes.
Be arranged on the top of filter module part 39 in order to the cleaning filtration equipment 51 of backwash filter module section 39. In the time that main treatment region 67 is sky, cleaning filtration equipment 51 moves. That is to say, when rain stops or during arid season, cleaning filtration equipment 51 moves with cleaning and filtering module section 39.
Cleaning filtration equipment 51 rotates by the reaction force of the expulsion pressure of the clean water by nozzle 51d and 51e injection, and the whole region that thus clean water is ejected into filter module part 39 rotates around this filter module part 39 simultaneously.
Fig. 5 is according to the stereogram of the cleaning filtration equipment 51 for water processing establishment of an embodiment, and Fig. 6 is the plane of describing the operation of Fig. 5 middle filtrator cleaning equipment 51. Fig. 7 is the partial sectional view that has schematically shown the internal structure of cleaning filtration equipment 51.
As shown in Figures 5 to 7, comprise for the cleaning filtration equipment 51 of water processing establishment 11: cylindrical bearing seat 51m, it is fixed to the upper middle part of filter module part 39, and is communicated with clean water supply pipe 51a; Water supply cover (hub) 51f, it is connected to the bottom of supporting base 51m in axial revolvable mode; Multiple clean water playpipe 51n, it has the respective rear ends that is fixed to water supply cover 51f, and extends longitudinally the inside of filter module section 39; And multiple nozzle 51e and 51d, it is arranged on clean water playpipe 51n.
Supporting base 51m is fixed by bearing support (not shown). Water by clean water supply pipe 51a supply is downward through the linkage path in supporting base 51m. Supporting base 51m is that supporting water supply cover 51f makes the axial revolvable member of water supply cover 51f. Use hold-down nut 51k supporting base 51m to be fixed to the lower end of clean water supply pipe 51a.
Water supply cover 51f is the cup-shaped member with closed lower end, and the water that flows through supporting base 51m is directed into clean water playpipe 51n.
In the time that water supply cover 51f support by supporting base 51m, water supply overlap 51f can be under the effect of external force axial-rotation. This external force is the reaction force of the expulsion pressure of the nozzle that will illustrate after a while. Can between supporting base 51m and water supply cover 51f, carriage be set on demand.
In this case, multiple cyclic lug 51t are formed on the outer surface of lower end of supporting base 51m, and are formed in order to support the support slot 51v of any protuberance 51t in the interior perimeter surface of water supply cover 51f.
Protuberance 51t has predetermined diameter and predetermined thickness. Protuberance 51t rotates along support slot 51v. Can be arranged on demand in this support slot 51v carriages such as bearing.
Clean water playpipe 51n comprises: the 51b of horizontal-extending portion, and its rear end is connected to water supply cover 51f and is communicated with water supply cover 51f; Multiple vertical extension 51c, it vertically extends and is communicated with the 51b of horizontal-extending portion; And multiple nozzle 51e and 51d, it is arranged in water extension 51b and vertical extension 51c.
The 51b of horizontal-extending portion is made up of two hollow tubes, and two hollow tubes extend in opposite direction and its rear end is fixed to water supply cover 51f. The 51b of horizontal-extending portion being positioned in a side of water supply cover 51f is longer than the 51b of horizontal-extending portion on opposite side. The relatively long 51b of horizontal-extending portion is configured to backwash the second fine mesh filter 45, and the relatively short 51b of horizontal-extending portion is configured to clean curtain formula filter part 41 and the first fine mesh filter 43.
Vertically extension 51c is the hollow tube that is connected to the 51b of horizontal-extending portion by T-connecting piece or elbow part. As shown in Figure 4, vertically extension 51c extends towards support plate 49.
The horizontal-extending portion being positioned in water supply cover 51f mono-side equates with the gross weight of vertical extension with the horizontal-extending portion on opposite side with the gross weight of vertical extension, and the 51b of this horizontal-extending portion is not tilted along a direction. That is to say, water supply cover 51f is as center of gravity.
Nozzle 51e and 51d comprise the top nozzle 51e being arranged in the 51b of horizontal-extending portion and are arranged on the side nozzle 51d in each vertical extension 51c.
