MBR is usually applied to secondary biological treatment. Due to its biological treatment and membrane filtration properties, its treatment water quality can reach the performance of tertiary treatment.
由污水與微生物反應後所產生的累積在反應器底端的污泥，其中含有高化學需氧量(Chemical oxygen demand,COD)、高濃度的微生物菌，可供回收再利用。然而，目前並無適當的回收技術，因此具有可改善的空間。 The sludge accumulated at the bottom of the reactor produced by the reaction of sewage and microorganisms, which contains high chemical oxygen demand (COD) and high concentration of microorganisms, can be recycled and reused. However, there is currently no suitable recycling technology and therefore there is room for improvement.

The foregoing structure is a common device in a general membrane bioreactor (MBR), and is not a creative feature of the present case, and is not described in detail herein.
本創作的特徵在於：該污水處理槽體30的底壁32設有一污泥出口11，位於該底壁32的一角落；一管體12，連接於該污泥出口11；一第一斜板13，設於該底壁32的內側，環繞於該污泥出口11並銜接該污泥出口11；以及一第二斜板14，設於該底壁32的內側，環繞於該第一斜板13並銜接該第一斜板13，而該第二斜板14的另端則連接至該等側壁31。該第一斜板13朝向該污泥出口11傾斜並具有一第一斜度；該第二斜14板朝向該污泥出口11傾斜並具有一第二斜度，其中該第一斜度大於第二斜度。 The present invention is characterized in that: the bottom wall 32 of the sewage treatment tank 30 is provided with a sludge outlet 11 at a corner of the bottom wall 32; a pipe body 12 is connected to the sludge outlet 11; a first inclined plate 13. disposed on the inner side of the bottom wall 32, surrounding the sludge outlet 11 and engaging the sludge outlet 11; and a second slanting plate 14 disposed on the inner side of the bottom wall 32 to surround the first slanting plate 13 and the first swash plate 13 is connected, and the other end of the second slanting plate 14 is connected to the side walls 31. The first inclined plate 13 is inclined toward the sludge outlet 11 and has a first inclination; the second inclined 14 plate is inclined toward the sludge outlet 11 and has a second slope, wherein the first slope is greater than the first slope Two slopes.
在本實施例中，該第一斜板13是由複數個板體拼接組成，該第二斜板14亦是由複數個板體拼接組成。一第一連接件15，設於該第一斜板13與該第二斜板14之間，用以連接該第一斜板13與該第二斜板14。在本實施例中，該第一連接件15係為一L型角鐵，除連接該第一斜板13與該第二斜板14，更連接該底壁32。一第二連接件16，設於該第一斜板13與該管體12之間，用以連接該第一斜板13與該管體12。在本實施例中，該第二連接件16係為一L型角鐵，除連接該第一斜板13與該管體12，更連接該底壁32。 In this embodiment, the first slanting plate 13 is composed of a plurality of slabs, and the second slanting plate 14 is also composed of a plurality of slabs. A first connecting member 15 is disposed between the first slanting plate 13 and the second slanting plate 14 for connecting the first slanting plate 13 and the second slanting plate 14. In this embodiment, the first connecting member 15 is an L-shaped angle iron, and the first inclined plate 13 and the second inclined plate 14 are connected to the bottom wall 32. A second connecting member 16 is disposed between the first slanting plate 13 and the tubular body 12 for connecting the first slanting plate 13 and the tubular body 12. In this embodiment, the second connecting member 16 is an L-shaped angle iron, and the bottom wall 32 is connected to the first inclined plate 13 and the tubular body 12.
在該污水處理槽體30中，污水經過複數薄膜過濾裝置(MBR)的反應作用後，利用膜微孔截留的作用，將厭氧或好氧系統的污泥截留在反應器中，通過提高污泥濃度、延長泥齡，達到排放標準或更高的水回收標準。由污水與微生物反應後所產生，累積在反應器底端的污泥，會掉到該污泥出口11、該第一斜板13、或該第二斜板14。該污泥掉落於該污泥出口11的，會直接排出；掉落於該第一斜板13的，經由自重及斜度作用，滑落至污泥出口11，然後排出；掉落 於該第二斜板14的，亦經相同作用，由斜度小的該第二斜板14進入斜度大的該第一斜板13，之後經由污泥出口11排出。 In the sewage treatment tank body 30, after the sewage is subjected to the reaction of the plurality of membrane filtration devices (MBR), the sludge of the anaerobic or aerobic system is trapped in the reactor by the action of the membrane micropores, and the sewage is enhanced. Mud concentration, prolonged mud age, meet emission standards or higher water recovery standards. The sludge accumulated at the bottom end of the reactor generated by the reaction of the sewage with the microorganisms may fall to the sludge outlet 11, the first slanting plate 13, or the second slanting plate 14. The sludge falls to the sludge outlet 11 and is directly discharged; the drop to the first sloping plate 13 is slid to the sludge outlet 11 by its own weight and inclination, and then discharged; The second swash plate 14 also enters the first slanting plate 13 having a large inclination by the second inclined plate 14 having a small inclination, and is discharged through the sludge outlet 11 .
由於該第一斜板13之斜度大於該第二斜板14之斜度，所以污泥會因自重的重力加速度漸增，而使滑落速度變快，使滑落動作作動順暢。最後致使污泥由該第二斜板14至該第一斜板13，滑落至該污泥出口11，然後從該污泥回收裝置中排出，不用另外再費工清潔該污水處理槽體30，達成省時、省工之功效。而其中含有高化學需氧量(Chemical oxygen demand,COD)、高濃度的微生物菌，可供回收利用。本發明即是利用此一特性，加上物理中斜面、萬有引力及自重之概念，使得在經過薄膜過濾裝置(MBR)作用後之污泥及含有高化學需氧量(Chemical oxygen demand,COD)、高濃度的微生物菌，得以回收利用。 Since the inclination of the first slanting plate 13 is greater than the inclination of the second slanting plate 14, the sludge will gradually increase in gravity due to its own weight, so that the sliding speed is increased, and the sliding action is smoothed. Finally, the sludge is caused to slide from the second slanting plate 14 to the first slanting plate 13 to the sludge outlet 11 and then discharged from the sludge recovery device without separately cleaning the sewage treatment tank 30. Achieve the effect of saving time and labor. It contains high chemical oxygen demand (COD) and high concentration of microbial bacteria for recycling. The present invention utilizes this feature, plus the concept of physical slope, gravitation and self-weight, so that the sludge and the chemical oxygen demand (COD) after being subjected to the membrane filtration device (MBR), High concentrations of microbial bacteria can be recycled.
