技术领域technical field
本实用新型属于生物填料曝气池技术领域，涉及一种生物填料固定式HMBR工艺曝气池。The utility model belongs to the technical field of biological filler aeration tanks and relates to a biological filler fixed HMBR process aeration tank.
背景技术Background technique
在普通膜生物反应器(CMBR)的曝气池中安装生物填料，运行一定时间后，填料上会生长一定厚度的生物膜，这种形式的膜生物反应器称之为复合式膜生物反应器(HMBR)。与CMBR相比，HMBR的曝气池中不仅具有悬浮性微生物(活性污泥)，还同时具有附着性微生物(生物膜)。试验结果表明，与CMBR相比，由于生物量明显提高，HMBR具有更好的生物降解能力。另外，与CMBR相比，HMBR还具有良好的膜污染控制能力，膜组件的运行周期大大延长。使用的生物填料是移动式生物填料，填料在曝气池中呈流化状态，HMBR的脱氮除磷能力并不理想。Install biological filler in the aeration tank of a common membrane bioreactor (CMBR), and after a certain period of operation, a certain thickness of biofilm will grow on the filler. This form of membrane bioreactor is called a composite membrane bioreactor. (HMBR). Compared with CMBR, there are not only suspended microorganisms (activated sludge) but also adherent microorganisms (biofilm) in the aeration tank of HMBR. The test results show that compared with CMBR, HMBR has better biodegradability due to the obvious increase of biomass. In addition, compared with CMBR, HMBR also has a good ability to control membrane fouling, and the operating cycle of the membrane module is greatly extended. The biological filler used is a mobile biological filler, and the filler is in a fluidized state in the aeration tank. The denitrification and phosphorus removal capabilities of HMBR are not ideal.

具体实施方式Detailed ways
下面结合具体实施方式对本实用新型进行详细说明。The utility model will be described in detail below in conjunction with specific embodiments.
本实用新型曝气池如图1所示，包括曝气池1，曝气池1内设有若干堵导流墙2，导流墙2与池壁之间设有膜组件3，膜组件3连接外部的自吸泵4，膜组件3下方设有曝气头5，曝气池1底部设有排泥管6，曝气池1内安装固定式生物填料7，原水通过格栅8被原水泵9抽入曝气池1内。As shown in Figure 1, the aeration tank of the utility model includes an aeration tank 1, a number of diversion walls 2 are arranged in the aeration tank 1, a membrane module 3 is arranged between the diversion wall 2 and the pool wall, and the membrane module 3 Connected to an external self-priming pump 4, an aeration head 5 is provided under the membrane module 3, a mud discharge pipe 6 is provided at the bottom of the aeration tank 1, a fixed biological filler 7 is installed in the aeration tank 1, and the raw water passes through the grill 8 The water pump 9 is drawn into the aeration tank 1.
在HMBR的曝气池1中安装导流墙2，将生物填料7固定安装在导流墙2与池壁之间。膜组件3安装在曝气池1的一侧靠近池壁处，下方设置曝气头5。曝气的作用有两个：一是提供微生物所需的溶解氧；二是上升气泡可以冲刷膜丝表面，有效控制膜污染。另外，气泡上升时会产生气提作用，使曝气池1中的混合液沿图中箭头方向流动。混合液流经生物填料7时，由于生物填料7固定安装，填料间的孔隙较小，容易截留、积聚大量的微生物(活性污泥和生物膜)，氧的传质阻力较大。在氧传质阻力的作用，混合液中的溶解氧浓度会逐渐降低，最终呈现缺氧甚至厌氧状态。因此，沿水流流动方向会交替出现好氧区、缺氧区和厌氧区。好氧区主要位于图中膜组件3所处的曝气池1右侧区域，运行时可将该区域上部混合液的溶解氧浓度控制在1mg/L左右。缺氧区主要位于生物填料7固定床的上部，厌氧区主要位于生物填料7固定床的下部。由于好氧区、缺氧区和厌氧区的交替出现，反应器可进行好氧条件下的硝化反应和吸磷反应，以及缺氧条件下的反硝化反应和厌氧条件下的释磷反应。因此，与安装流化态生物填料的HMBR相比，安装固定式生物填料的HMBR具有更好的脱氮除磷能力。The diversion wall 2 is installed in the aeration tank 1 of the HMBR, and the biological filler 7 is fixedly installed between the diversion wall 2 and the pool wall. The membrane module 3 is installed on one side of the aeration tank 1 close to the tank wall, and the aeration head 5 is arranged below. Aeration has two functions: one is to provide the dissolved oxygen needed by microorganisms; the other is that rising air bubbles can scour the surface of the membrane filaments to effectively control membrane fouling. In addition, when the air bubbles rise, an airlift effect will be generated, so that the mixed liquid in the aeration tank 1 will flow in the direction of the arrow in the figure. When the mixed liquid flows through the biological filler 7, because the biological filler 7 is fixedly installed, the pores between the fillers are small, and a large amount of microorganisms (activated sludge and biofilm) are easily retained and accumulated, and the mass transfer resistance of oxygen is relatively large. Under the effect of oxygen mass transfer resistance, the dissolved oxygen concentration in the mixed solution will gradually decrease, and finally present anoxic or even anaerobic state. Therefore, aerobic zones, anoxic zones and anaerobic zones alternately appear along the direction of water flow. The aerobic zone is mainly located in the area on the right side of the aeration tank 1 where the membrane module 3 is located in the figure. During operation, the dissolved oxygen concentration of the mixed liquid in the upper part of this area can be controlled at about 1mg/L. The anoxic zone is mainly located in the upper part of the fixed bed of biological filler 7, and the anaerobic zone is mainly located in the lower part of the fixed bed of biological filler 7. Due to the alternate appearance of aerobic zone, anoxic zone and anaerobic zone, the reactor can carry out nitrification reaction and phosphorus absorption reaction under aerobic conditions, as well as denitrification reaction under anoxic conditions and phosphorus release reaction under anaerobic conditions . Therefore, compared with the HMBR installed with fluidized biological filler, the HMBR installed with fixed biological filler has better nitrogen and phosphorus removal capacity.
以上所述仅是对本实用新型的较佳实施方式而已，并非对本实用新型作任何形式上的限制，凡是依据本实用新型的技术实质对以上实施方式所做的任何简单修改，等同变化与修饰，均属于本实用新型技术方案的范围内。The above description is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any simple modification made to the above implementation method according to the technical essence of the utility model is equivalent to changes and modifications. All belong to the scope of the technical solution of the utility model.
