本实用新型的要解决的技术问题是，提供一种膜生物反应器与活性污泥联用污水处理装置。 The technical problem to be solved by the utility model is to provide a sewage treatment device combined with a membrane bioreactor and activated sludge.
为解决上述技术问题，本实用新型的技术方案如下： For solving the problems of the technologies described above, the technical scheme of the utility model is as follows:
一种膜生物反应器与活性污泥联用污水处理装置，包括有配水箱和曝气池，所述的配水箱通过水泵与曝气池相连通，曝气池一侧设置有空气压缩机，空气压缩机的管道上设置玻璃转子流量计，曝气池的右边部分设置有液位计，液位计连接至液位控制器；所述的曝气池分为左和右两个部分，曝气池的左边部分是活性污泥处理系统，活性污泥处理系统由曝气池和与之相连通的沉淀池组成；曝气池的右边部分是膜生物反应器处理系统，属于膜生物反应器处理系统的曝气池中安装有与外接蠕动泵相连接的中空纤维膜组件，蠕动泵与中空纤维膜组件之间安装有真空压力表。 A sewage treatment device combined with membrane bioreactor and activated sludge, including a water distribution tank and an aeration tank, the water distribution tank is connected to the aeration tank through a water pump, and an air compressor is arranged on one side of the aeration tank, The pipeline of the air compressor is provided with a glass rotameter, and the right part of the aeration tank is provided with a liquid level gauge, which is connected to the liquid level controller; the aeration tank is divided into left and right parts, and the aeration The left part of the aeration tank is the activated sludge treatment system, which is composed of the aeration tank and the sedimentation tank connected to it; the right part of the aeration tank is the membrane bioreactor treatment system, which belongs to the membrane bioreactor A hollow fiber membrane module connected to an external peristaltic pump is installed in the aeration tank of the treatment system, and a vacuum pressure gauge is installed between the peristaltic pump and the hollow fiber membrane module.
所述的沉淀池的一侧开有出水口。 A water outlet is opened on one side of the sedimentation tank.
实际使用时，进水采用人工配水至配水箱，经进水泵抽吸到生物反应器CAS系统中，其中的污染物经活性污泥中的微生物分解，处理出水在蠕动泵的负压抽吸作用下经膜组件过滤后获得。反应器的液位由液位控制器进行控制，当水位达到最低进水液位时，水泵自动进水；当水位达到最高进水液位时，停止进水；当水位达到最低出水液位时，从蠕动泵处停止出水；其他状态下保持正常出水。空气压缩机连续运行，曝气方式为连续曝气方式，为曝气池提供充足的氧气。曝气量采用转子流量计进行调节。蠕动泵采取间歇运行方式，抽歇时间为9min/6min。真空压力表监测试验过程中中空纤维膜上的过滤压力变化情况。在曝气池中经活性污泥分解后的混合液溢流到沉淀池，经沉淀后，从出水口得到处理出水。沉淀污泥通过隔板底部的通道或虹吸作用回流到曝气池，利用进水泵的开启来控制反应器内的液位恒定。 In actual use, the influent water is manually distributed to the water distribution tank, and is pumped into the bioreactor CAS system by the influent pump, and the pollutants in it are decomposed by the microorganisms in the activated sludge, and the treated effluent is sucked by the negative pressure of the peristaltic pump obtained after filtration through a membrane module. The liquid level of the reactor is controlled by the liquid level controller. When the water level reaches the lowest water inlet level, the water pump automatically feeds water; when the water level reaches the highest water inlet level, the water inlet stops; when the water level reaches the lowest water outlet level , stop the water output from the peristaltic pump; keep normal water output in other states. The air compressor runs continuously, and the aeration method is a continuous aeration method to provide sufficient oxygen for the aeration tank. The aeration rate is adjusted by a rotameter. The peristaltic pump adopts intermittent operation mode, and the pumping time is 9min/6min. The vacuum pressure gauge monitors the change of filtration pressure on the hollow fiber membrane during the test. The mixed liquid decomposed by the activated sludge in the aeration tank overflows to the sedimentation tank, and after sedimentation, the treated water is obtained from the water outlet. The settled sludge flows back to the aeration tank through the channel or siphon at the bottom of the partition, and the liquid level in the reactor is controlled to be constant by the opening of the inlet pump.
