上述反应器的运行过程如下所述：The operation process of the above-mentioned reactor is as follows:
废水由废水管13进入各个布水器3中，沿布水支管13通过布水喷头14喷出，向四周呈辐射状喷出，产生不间断的旋转式液流，废水能在整个反应器内实现均匀的分布，并且在进水动力的推动下，颗粒污泥与废水朝同一个方向运动，在同样推力作用下由于废水与颗粒污泥的密度不同，其流速也会有所不同，这就使得废水与污泥更充分的接触与传质。The waste water enters each water distributor 3 through the waste water pipe 13, and is sprayed out through the water distribution nozzle 14 along the water distribution branch pipe 13, and is sprayed radially to the surroundings, generating an uninterrupted rotating liquid flow, and the waste water can flow in the entire reactor. Achieve uniform distribution, and under the impetus of water inlet power, granular sludge and wastewater move in the same direction. Under the same thrust, due to the different density of wastewater and granular sludge, their flow rates will also be different, which is Make the wastewater and sludge more fully contact and mass transfer.
同时，压缩空气通过曝气管6进入各曝气装置4，通过曝气分配体15进入各曝气支管16，由曝气支管16上水平方向及竖直方向的曝气头喷入泥水混合液中，一方面为微生物提供空气，一方面搅动泥水混合液，剧烈传质。At the same time, the compressed air enters each aeration device 4 through the aeration pipe 6, enters each aeration branch pipe 16 through the aeration distribution body 15, and sprays the mud-water mixture from the horizontal and vertical aeration heads on the aeration branch pipe 16. In the process, on the one hand, air is provided for the microorganisms, on the other hand, the mud-water mixture is stirred, and the mass transfer is violent.
旋转式的布水以及全方位的曝气使得泥水混合更加充分，反应器内废水自下至上全程参与传质，传质更为剧烈，大大提高了传质效率。高浓度的有机废水在短时间内与微生物充分接触，为颗粒物的快速繁殖提供充足的营养物质，促进生物繁殖，同时借助高速剪切和冲刷，大大提高了混合效率和传质效率，快速形成好氧颗粒污泥，微生物与有机污染物充分吸附降解，参与污染物的去除。The rotating water distribution and all-round aeration make the mud water mix more fully, and the wastewater in the reactor participates in the mass transfer from bottom to top, and the mass transfer is more intense, which greatly improves the mass transfer efficiency. High-concentration organic wastewater is in full contact with microorganisms in a short period of time, providing sufficient nutrients for the rapid reproduction of particulate matter, and promoting biological reproduction. At the same time, with the help of high-speed shearing and scouring, the mixing efficiency and mass transfer efficiency are greatly improved. Oxygen granular sludge, microorganisms and organic pollutants are fully adsorbed and degraded, and participate in the removal of pollutants.
泥水混合液上升到气液分离罩10后实现气液分离，处理后的废水由气液分离罩10与池体1内壁之间的升流缝上升，多余气体由排气口11排出，同时大颗粒污泥被气液分离罩10阻挡落下。清液经沉淀区过滤区7过滤进入出水堰9，然后沿出水管8排出池体外，污泥在重力的作用下向池底沉降，经排泥管2定期排出池外。After the muddy water mixture rises to the gas-liquid separation cover 10, the gas-liquid separation is realized, and the treated waste water rises from the upflow gap between the gas-liquid separation cover 10 and the inner wall of the tank body 1, and the excess gas is discharged from the exhaust port 11, and the large The granular sludge is prevented from falling by the gas-liquid separation cover 10 . The clear liquid is filtered into the outlet weir 9 through the filtration area 7 of the sedimentation area, and then discharged out of the pool along the outlet pipe 8, and the sludge settles to the bottom of the pool under the action of gravity, and is regularly discharged out of the pool through the mud discharge pipe 2.
