Description
技术领域technical field
本实用新型涉及一种膜生物反应器，尤其涉及一种一体式膜生物反应器。The utility model relates to a membrane bioreactor, in particular to an integrated membrane bioreactor.
背景技术Background technique
膜生物反应器技术是一项新兴的水处理新技术，是传统生物处理工艺与膜分离技术的有机结合，已成功地应用于水处理。膜生物反应器一般由膜分离组件及生物反应器两部分组成，根据膜组件设置的位置，主要分为分置式和淹没式两种。淹没式的膜生物反应器组合工艺是将膜组件置入生物反应器内，经过膜得到滤液，悬浮物及活性污泥等物质被截留在生物反应器内，对于高氨氮、高有机物的微污染水源水或当污泥浓度过高时使膜的过滤通量降低，阻力增大，增加了能耗，运行管理不便。Membrane bioreactor technology is a new water treatment technology, which is an organic combination of traditional biological treatment process and membrane separation technology, and has been successfully applied to water treatment. Membrane bioreactors are generally composed of membrane separation modules and bioreactors. According to the location of membrane modules, they are mainly divided into two types: split type and submerged type. The submerged membrane bioreactor combination process is to put the membrane module into the bioreactor, and obtain the filtrate through the membrane, and the suspended solids and activated sludge are trapped in the bioreactor, which is suitable for micro-pollution with high ammonia nitrogen and high organic matter. When the source water or the sludge concentration is too high, the filtration flux of the membrane is reduced, the resistance is increased, the energy consumption is increased, and the operation and management are inconvenient.
发明内容Contents of the invention
本实用新型是针对现有技术所存在的缺点，而提供了一种一体式膜生物反应器的技术方案，该方案采用在微污染水经过膜组件之前设置有生物活性炭过滤层的一次净化装置，其结构简单，制造成本低，净化效果好。The utility model aims at the shortcomings of the prior art, and provides a technical solution of an integrated membrane bioreactor, which adopts a primary purification device provided with a biological activated carbon filter layer before the slightly polluted water passes through the membrane module, The structure is simple, the manufacturing cost is low, and the purification effect is good.
本实用新型是通过如下技术措施实现的：它包括滤池，在滤池的底部设置有进水口，在滤池内靠近底部并在进水口的上方设置有生物活性炭滤层，在生物活性炭滤层的上部设置有膜组件。The utility model is realized through the following technical measures: it includes a filter tank, a water inlet is arranged at the bottom of the filter tank, a biological activated carbon filter layer is arranged near the bottom in the filter tank and above the water inlet, and a biological activated carbon filter layer is arranged on the bottom of the filter tank The upper part is provided with a membrane module.
在所述的膜组件的底部，生物活性炭滤层的上部设置有曝气装置。在膜组件底部设曝气管，以对膜组件进行清洗，其曝气强度只需满足清洗的要求。这是因为不需要生物活性炭在水中流化，因此，曝气强度较低。At the bottom of the membrane module, an aeration device is arranged on the upper part of the biological activated carbon filter layer. An aeration pipe is installed at the bottom of the membrane module to clean the membrane module, and the aeration intensity only needs to meet the cleaning requirements. This is because the BAC does not need to be fluidized in the water, therefore, the aeration intensity is lower.
在生物活性炭滤层底部设置有曝气装置和反冲洗装置。这样可以在进水氨氮较高时进行曝气充氧并定期对生物活性炭滤池反冲洗，保持其清洁通畅。具体包括与生物活性炭滤层底部腔体连接的滤池曝气管和滤池反冲气管。在滤池的上部设置有净水出水口。所述的滤池底部设置的进水口与滤池进水管和滤池反冲进水管连接。An aeration device and a backwashing device are arranged at the bottom of the biological activated carbon filter layer. In this way, aeration and oxygenation can be carried out when the ammonia nitrogen in the influent is high, and the biological activated carbon filter can be backwashed regularly to keep it clean and smooth. Specifically, it includes a filter aeration pipe and a filter recoil air pipe connected to the bottom cavity of the biological activated carbon filter layer. A clean water outlet is arranged on the upper part of the filter tank. The water inlet provided at the bottom of the filter is connected with the filter water inlet pipe and the filter backwash water inlet pipe.
该实用新型可以采用如下方式设计装配，将生物活性炭滤池炭层以上的空间加高，将膜组件放在滤层上部的水中，当滤池水位与清水池水位高差较大，可利用水位差出水，降低运行费用，生物活性炭滤池采用向上流方式，池底部进水，并在池底部曝气，曝气量根据进水氨氮浓度，气∶水一般不超过0.5∶1，当有臭氧氧化工艺且采用纯氧为臭氧气源时，可不曝气。通常由于曝气量小，生物活性炭滤层仍保持固定床的状态，经生物活性炭滤层处理的水在上部通过膜组件过滤出水，在膜组件底部设曝气管，以对膜组件进行清洗，曝气强度只需满足清洗的要求。由于不需要生物活性炭在水中流化，因此，曝气强度较低。在生物活性炭滤池底部设置反冲洗装置，定期对生物活性炭滤池反冲洗。虽然对生物活性炭滤池进行曝气，由于膜组件的过滤截留作用，不存在生物活性炭的流失问题，由于对生物活性炭滤层曝气，解决了高氨氮情况下生物活性炭滤池中溶解氧不足的问题，保证了对氨氮的去除。The utility model can be designed and assembled in the following way. The space above the carbon layer of the biological activated carbon filter is increased, and the membrane module is placed in the water above the filter layer. Poor water output, lower operating costs, biological activated carbon filter adopts upward flow method, water enters the bottom of the pool, and aerates at the bottom of the pool, the aeration rate is based on the ammonia nitrogen concentration of the incoming water, and the air: water generally does not exceed 0.5: 1. When there is ozone When the oxidation process is used and pure oxygen is used as the ozone source, no aeration is required. Usually, due to the small amount of aeration, the biological activated carbon filter layer still maintains a fixed bed state, and the water treated by the biological activated carbon filter layer passes through the membrane module to filter the water in the upper part, and an aeration tube is installed at the bottom of the membrane module to clean the membrane module. The aeration intensity only needs to meet the cleaning requirements. The aeration intensity is low because there is no need for bioactivated carbon to be fluidized in water. A backwashing device is installed at the bottom of the biological activated carbon filter to backwash the biological activated carbon filter regularly. Although the biological activated carbon filter is aerated, due to the filtration and interception of the membrane module, there is no loss of biological activated carbon. Due to the aeration of the biological activated carbon filter layer, the problem of insufficient dissolved oxygen in the biological activated carbon filter under the condition of high ammonia nitrogen is solved. problem, ensuring the removal of ammonia nitrogen.
