Embodiment
The present invention provides a kind of deposit retracting device of sewage disposal system, please refer to shown in Fig. 1 to Fig. 3, wraps
Contain：
One sewage disposal cell body 30, it is made up of four side walls 31 and a bottom wall 32, wherein forming a processing space 33.Should
Processing space 33 can be equiped with the sewage disposal devices such as membrane filtration device (not shown), aerator (not shown).Foregoing
Structure belongs to device common in general membrane bioreactor (MBR), the creation characteristic of non-category this case, holds be not described in detail herein.
This creation is characterised by：The bottom wall 32 of the sewage disposal cell body 30 is provided with deposit outlet 11, positioned at the bottom
One corner of wall 32；One body 12, it is connected to deposit outlet 11；One first swash plate 13, located at the inner side of the bottom wall 32, ring
It is around in deposit outlet 11 and is connected deposit outlet 11；And one second swash plate 14, located at the inner side of the bottom wall 32, ring
It is around in first swash plate 13 and is connected first swash plate 13, and the another end of second swash plate 14 is then connected to such side wall 31.Should
First swash plate 13 tilts towards deposit outlet 11 and has one first gradient；Second oblique 14 plate exports towards the deposit
11 tilt and have one second gradient, and wherein first gradient is more than the second gradient.
In the present embodiment, first swash plate 13 is made up of the splicing of a plurality of plate bodys, and second swash plate 14 is also by multiple
Several plate body splicing compositions.One first connector 15, between first swash plate 13 and second swash plate 14, to connect this
First swash plate 13 and second swash plate 14.In the present embodiment, first connector 15 is a L-type angle bar, except connect this first
Swash plate 13 and second swash plate 14, are also connected with the bottom wall 32.One second connector 16, located at first swash plate 13 and the body 12
Between, to connect first swash plate 13 and the body 12.In the present embodiment, second connector 16 is a L-type angle bar, is removed
First swash plate 13 and the body 12 are connected, is also connected with the bottom wall 32.
In the sewage disposal cell body 30, sewage utilizes film after plural membrane filtration device (MBR) reagentia
The effect of microporous entrapment, by the retention of the deposit of anaerobism or aerobic system in the reactor, by improving deposit concentration, extending
Sludge age, reach the Water Sproading standard of discharge standard or higher.Produced by after sewage and microbial reaction, accumulate at reactor bottom
The deposit at end, deposit outlet 11, first swash plate 13 or second swash plate 14 can be dropped to.The deposit drops in this
Deposit outlet 11, it can be expelled directly out；Drop in first swash plate 13, acted on via deadweight and gradient, slid to deposition
Thing outlet 11, is then discharged out；Drop in second swash plate 14, also through phase same-action, entered by small second swash plate 14 of gradient
Enter big first swash plate 13 of gradient, afterwards via the discharge of deposit outlet 11.
Because the gradient of first swash plate 13 is more than the gradient of second swash plate 14, so deposit can be because of the gravity of deadweight
Acceleration is cumulative, and slip velocity is accelerated, and makes landing action start smooth.Finally cause deposit by second swash plate 14 to
First swash plate 13, slide to deposit outlet 11, then discharged from the deposit retracting device, without taking a lot of work again in addition
The sewage disposal cell body 30 is cleaned, the effect of reaching time saving, saving of labor.And wherein contain high chemical oxygen demand (Chemical
Oxygen demand, COD), the microbial bacteria of high concentration, be available for recycling.The present invention is using this characteristic, is added
Inclined-plane, gravitation and the concept of deadweight in physics so that in the deposit after membrane filtration device (MBR) effect and contain
There are high chemical oxygen demand (Chemical oxygen demand, COD), the microbial bacteria of high concentration, recycled.
