一、MBR工艺的特点
1、 对污染物的去除效率高
MBR对悬浮固体(SS)浓度和浊度有着非常良好的去除效果。由于膜组件的膜孔径非常小(0.01~1µm)，可将生物反应器内全部的悬浮物和污泥都截留下来，其固液分离效果要远远好于二沉池，MBR对SS的去除率在99%以上，甚至达到100%；浊度的去除率也在90%以上，出水浊度与自来水相近。
由于膜组件的高效截留作用，将全部的活性污泥都截留在反应器内，使得反应器内的污泥浓度可达到较高水平，最高可达40~50g/L。这样，就大大降低了生物反应器内的污泥负荷，提高了MBR对有机物的去除效率，对生活污水COD的平均去除率在94%以上，BOD的平均去除率在96%以上。
同时，由于膜组件的分离作用，使得生物反应器中的水力停留时间(HRT)和污泥停留时间(SRT)是完全分开的，这样就可以使生长缓慢、世代时间较长的微生物(如硝化细菌)也能在反应器中生存下来，保证了MBR除具有高效降解有机物的作用外，还具有良好的硝化作用。研究表明，MBR在处理生活污水时，对氨氮的去除率平均在98%以上，出水氨氮浓度低于1mg/L。
此外，选择合适孔径的膜组件后，MBR对细菌和病毒也有着较好的去除效果，这样就可以省去传统处理工艺中的消毒工艺，大大简化了工艺流程。
另外，在DO浓度较低时，在菌胶团内部存在缺氧或厌氧区，为反硝化创造了条件。仅采用好氧MBR工艺，虽然对TP的去除效率不高，但如果将其与厌氧进行组合，则可大大提高TP的去除率。研究表明，采用A/O复合式MBR工艺，对TP的去除率可达70%以上。
2、具有较大的灵活性和实用性
在城市污水或工业废水处理中，传统的处理工艺(格栅+沉砂池+初沉池+曝气池+二沉池+消毒池)流程较长，占地面积大，而出水水质又不能保证。而MBR工艺(筛网过滤+MBR)则因流程短、占地面积小!处理水量灵活等特点，而呈现出明显优势#MBR的出水量根据实际情况，只需增减膜组件的片数就可完成产水量调整，非常简单、方便。
对于传统的活性污泥法工艺中出现的污泥膨胀现象，MBR由于不用二沉池进行固液分离，可以轻松解决。这样，就大大减轻了管理操作的复杂程度，使优质!稳定的出水成为可能。
同时，MBR工艺非常易于实现自动控制，提高了污水处理的自动化水平。
3、解决了剩余污泥处置难的问题
剩余污泥的处置问题，是污水处理厂运行好坏的关键问题之一#MBR工艺中，污泥负荷非常低，反应器内营养物质相对缺乏，微生物处在内源呼吸区，污泥产率低，因而使得剩余污泥的产生量很少，SRT得到延长，排除的剩余污泥浓度大，可不用进行污泥浓缩，而直接进行脱水，这就大大节省了污泥处理的费用。有研究得出，在处理生活污水时，MBR最佳的排泥时间在35d左右。
由上述可知，MBR工艺所具有的优越性，是目前其他处理工艺无法比拟的#该工艺在城市污水或生活污水处理!高浓度有机废水、难降解有机废水以及中水回用等方面都具有广阔的应用前景。

Membrane bioreactor (Membrane Biological Reactor, MBR) is a new and efficient sewage treatment technology composed of membrane separation and biological treatment. Membrane separation technology was first applied in microbial fermentation industry. With the development of membrane materials and film making technology, its application field is expanding, and it has been involved in chemical industry, electronics, light industry, textile, metallurgy, food, petrochemical industry and sewage treatment and other fields. Chinese enlightenment can export MBR domestic sewage treatment equipment, the following small series will introduce MBR integrated domestic sewage treatment equipment in detail.
1. Characteristics of the MBR process
1. High removal efficiency of pollutants
MBR has a very good removal effect on the concentration and turbidity of suspended solid (SS). Because the membrane aperture of the membrane component is very small (0.01~1 µ m), all the suspended matter and sludge in the bioreactor can be trapped, and the solid-liquid separation effect is much better than that of the secondary sedimentation tank. The SS removal rate of MBR is above 99% or even 100%; the removal rate of turbidity is above 90%, and the turbidity of effluent is similar to that of tap water.
Due to the efficient interception of membrane components, all the activated sludge is trapped in the reactor, so that the sludge concentration in the reactor can reach a high level, up to 40~50g / L. In this way, the sludge load in the biological reactor is greatly reduced, and the removal efficiency of MBR for organic matter is improved. The average removal rate of COD of domestic sewage is more than 94%, and the average removal rate of BOD is more than 96%.
At the same time, due to the separation of membrane components, makes the biological reactor in the water stay time (HRT) and sludge stay time (SRT) is completely separated, so can make slow growth, generation long microorganisms (such as nitrification bacteria) can survive in the reactor, ensure the MBR in addition to the effect of efficient degradation of organic matter, also has a good nitrification. The study shows that when MBR treats domestic sewage, the average removal rate of ammonia nitrogen is more than 98%, and the concentration of ammonia nitrogen in the effluent is less than 1 mg/L.
In addition, after selecting the membrane component with the appropriate aperture, MBR also has a good removal effect on the bacteria and viruses, so as to eliminate the disinfection process in the traditional treatment process and greatly simplify the process process.
In addition, at low DO concentrations, there are hypoxic or anaerobic zones within the bacterial micelle, creating conditions for denitrification. Using aerobic MBR process only, although the removal efficiency of TP is not high, the TP removal rate is greatly improved. The study shows that the A / O composite MBR process can remove more than 70% of TP.
2. Enterprise introduction
2, with greater flexibility and practicality
In the treatment of urban sewage or industrial wastewater, the traditional treatment process (grille + sand sedimentation tank + primary sedimentation tank + aeration tank + two sedimentation tank + disinfection tank) has a long process, covers a large area, and the effluent water quality can not be guaranteed. The MBR process (screen filter + MBR) is due to the short process, small footprint! According to the actual situation, the water output of # MBR can be adjusted only by increasing or decreasing the number of pieces of membrane components, which is very simple and convenient.
For the sludge swelling phenomenon appeared in the traditional activated sludge process, MBR can be easily solved without solid-liquid separation in the secondary sedimentation tank. In this way, greatly reduce the complexity of management operation, so that high quality! Stable effluent becomes possible.
At the same time, the MBR process is very easy to achieve automatic control, improve the level of automation of sewage treatment.
3. Solved the problem of difficult disposal of surplus sludge
Residual sludge disposal problem, is one of the key problems of sewage treatment plant operation # MBR process, sludge load is very low, the reactor relative lack of nutrients, microorganisms in endogenous respiratory area, sludge yield is low, thus making the production of residual sludge, SRT extended, eliminate the surplus of the sludge concentration, can not for sludge concentration, and direct dehydration, this will greatly save the cost of sludge treatment. Some studies have concluded that the best mud discharge time for MBR is about 35d when treating domestic sewage.
From the above, the advantages of MBR process is incomparable to other treatment process in urban sewage or domestic sewage treatment! High concentration organic wastewater, difficult to degrade organic wastewater and reclaimed water reuse have broad application prospects.
