1、MBBR工艺
MBBR工艺中以填料为载体，可以为细菌提供附着点，从而使菌群更丰富多样，生物量增加。在好氧反应阶段，由于空气的进入使悬浮填料在曝气的过程均匀分布在系统中，整个系统就会产生由空气、填料和水组成的一个三项环境。悬浮填料在曝气过程会受气体推动从而进行不规则运动，整个三项环境固液气相互混合，外界进入的气体可更好地均匀分布于系统中，整个过程都给好氧反应提供了最好的条件。一个MBBR一体化设备由多个系统共同组成如悬浮载体、进出水等。从设计上出发悬浮载体即填料的选择，以及投加量的确定，将影响填料上的生物膜有效面积，另外关于搅拌器选型、曝气量风机选型、滤池方案的设计等都需要酌情考虑。现实相关工程更需要对各项环境要素进行考虑，对生物膜附着生物稳定生长和稳定运行都有相关影响，曝气量的控制、pH的调节，以及溶解氧的浓度都和微生物长成有着极大影响，进而直接影响填料的挂膜和填料是否均匀分布于空间使好氧反应过程得到保证。不断对MBBR系统进行优化以及对MBBR相关组合工艺进行探索创新将是一个极具价值的方向。

（6）中侨启迪通过对反应器流体力学的研究，确定反应器的形状，可达到最优化的反应器结构，从而避免填料堆积，降低能耗。
2、MBBR与组合工艺
组合工艺的提出让MBBR工艺的经济效益和运用价值得到了更进一步的提升，近年MBBR与组合工艺广泛应用于处理城镇生活污水、工业污水、高负荷有机废水以及垃圾渗滤液。例如厌氧生物滤池-好氧移动床工艺对垃圾填埋场渗滤液进行处理，取得较优的氨氮去除效果;通过对化学法与移动床生物反应器组合工艺的脱氮除磷效果优化分析，以及活性污泥组合工艺在废水处理中有着占地省、运作稳、同时处理效率高可取之处。
（1）A/O+MBBR组合工艺
A/O+MBBR组合工艺不仅存在抗冲击负荷的能力，也能同时提高污水日处理量。
组合工艺中MBBR工艺能确保整体生物量的增长，加强整体耐低温性能。和A/O工艺进行对比，相同工况前提下组合工艺可以增加每天的处理量，抗冲击负荷能力强。在节能减排的前提下保证出水水质。相同工况运行下COD、NH3-N和TN的平均除去效果比A/O工艺好。
（2）A2/O+MBBR组合工艺
MBBR+A2/O组合工艺，可提高生化单元微生物总量，对COD、氨氮、TN、TP等污染指标的去除效果显著。值得一提的是实际项目表明在整个组合工艺中厌氧区生物量最大，其次是缺氧区，最后是好氧区，实际设计中，相关容积比也应进行考虑。
（3）MBR+MBBR组合工艺
中侨启迪对某垃圾填埋场渗滤液处理工程进行改造升级通过用“水解-厌氧MBBR-好氧MBBRMBR”为主体的工艺。从新工程正常运行相关数据发现，当垃圾渗滤液中的COD、NH3-N、全盐量处在2000～15000mg/L、50～1000mg/L、2000～20000mg/L阶段时，最后通过设备相关生化处理可以达到渗滤液一级出水标准。
MBBR组合工艺能否推广使用，不仅要考虑其技术可行性，还要考虑经济可行性，要想切实实现水资源循环利用，更应加强污水的深度处理和回用方法的推进。多级MBBR、MBBR和A/O、MBBR和A2/O、MBBR和MBR法联合工艺等都具有各自的可取之处，组合工艺的选取和应用需要结合实际进行考量，让效益最大化，让经济最优化。组合工艺的脱氮效果和除磷效果更强，运行更稳定，污染物处理效率更高，可大幅度使生物污泥产量减少，出水营养物质含量降低在未来很长一段时间里都具有很大的应用价值。

欢迎您来厂考察合作!
Mobile bed biofilm reactor (MBBR) has a history of more than ten years. It is a new and efficient composite sewage treatment process developed on the basis of fixed bed reactor, fluidized bed reactor and biofilter. The following xiaobian will introduce to you the process combination of foreign trade MBBR integrated sewage treatment equipment.
1, the MBBR process
In the MBBR process, filler can provide attachment points for bacteria, thus making the bacterial flora more abundant and diverse and increasing the biomass. In the aerobic reaction stage, because the entry of air makes the suspended packing evenly distributed in the system during the process of aeration, the whole system will produce a three-item environment composed of air, filler and water. In the process of aeration, the suspended packing will be driven by the gas for irregular movement. The whole three environmental solid-liquid gas are mixed with each other, and the gas entering the outside world can be better evenly distributed in the system, and the whole process provides the best conditions for the aerobic reaction. An integrated MBBR equipment is composed of multiple systems, such as suspension carrier, water in and outlet, etc. Starting from the design, the selection of the suspension carrier, namely the filler, and the determination of the loading amount will affect the effective area of the biofilm on the filler. In addition, the selection of the agitator, the selection of the aeration fan and the design of the filter scheme need to be considered as appropriate. Reality related engineering more need to consider the environmental elements, the biofilm attached biological stable growth and stable operation have related influence, aeration control, pH regulation, and the concentration of dissolved oxygen and microorganisms has a great influence, and directly affect the packing hanging film and packing is evenly distributed in the space to the aerobic reaction process is guaranteed. Continuous optimization of MBBR system and exploring and innovating MBBR related combination processes will be a very valuable direction.
Advantages of the Chinese overseas enlightenment MBBR integrated sewage treatment equipment:
(1) Good nitrogen removal capacity: aerobic, hypoxia and anaerobic environment are formed on the packing, and the nitrification and denitrification reaction can occur in a reactor, which has a good effect on the removal of ammonia nitrogen.
(2) Good removal of organic matter: the sludge concentration in the reactor is high, the general sludge concentration is 5~10 times of the ordinary activated sludge method, can be up to 30~40g / L. Improve the treatment efficiency of organic matter, and the impact load resistance capacity is strong.
(3) Easy maintenance and management: there is no need to set up the packing support in the aeration tank, which is convenient to maintain the packing material and the aeration device at the bottom of the pool.
(4) The chemical characteristics of the filler surface and the shedding mechanism of the suspended filler, increasing the specific surface area of the filler, using activated carbon, starch and gelatin as biological active additives, so that the suspended filler can promote the growth and reproduction of microorganisms.
(5) Multi-stage MBBR, MBBR and A / O combined process all have their own advantages, and A series of practical applications of these combined process combinations.
(6) Through the study of reactor hydrodynamics, we determine the shape of the reactor, which can achieve the optimal reactor structure, so as to avoid packing accumulation and reduce energy consumption.
2. MBBR and the combined process
The proposal of combined process has further improved the economic benefit and application value of MBBR process. In recent years, MBBR and combined process are widely used in the treatment of urban domestic sewage, industrial sewage, high-load organic wastewater and landfill leachate. For example, the anaerobic biological filter-aerobic mobile bed process treats landfill leachate and achieve better ammonia nitrogen removal effect, through the optimization analysis of nitrogen and phosphorus removal effect of chemical method and mobile bed bioreactor, and the activated sludge combination process has land space, stable operation and high treatment efficiency in wastewater treatment.
(1) A / O + MBBR combination process
The A / O + MBBR combination process not only has the ability to resist the impact load, but also improves the daily sewage treatment capacity.
The MBBR process in the combined process ensures the overall biomass growth and strengthens the overall low temperature resistance. Compared with A / O process, the combined process can increase the daily processing capacity under the same working condition, and has strong resistance to impact load. Under the premise of energy conservation and emission reduction to ensure the effluent water quality. The average removal effect of COD, NH3-N and TN under the same operating condition is better than the A / O process.
(2) A2 / O + MBBR combination process
The MB BR + A2 / O combination process can increase the total amount of microorganisms in the biochemical unit, and have a significant removal effect on the pollution indexes such as COD, ammonia nitrogen, TN and TP. It is worth mentioning that the actual project indicates that the anaerobic area has the largest biomass in the whole combined process, followed by the hypoxic area, and finally the aerobic area. In the actual design, the relevant volume ratio should also be considered.
(3) MBR + MBBR combination process
Zhongqi Qiao Qi upgraded the leachate treatment project of a landfill site by using the process of "hydrolysis-anaerobic MBBR-aerobic MBBRMBR" as the main body. According to the relevant data related to the normal operation of the new project, when the COD, NH3-N and full salt amount in the landfill leachate are at 2000 ~ 15000 mg/L, 50 ~ 1000 mg/L and 2000 ~ 20000 mg/L, the first level effluent standard of the leachate can be reached through the relevant biochemical treatment of the equipment.
Whether the MBBR combination process can be popularized should not only consider its technical feasibility, but also consider its economic feasibility. In order to effectively realize the recycling of water resources, the depth of sewage treatment and reuse method should be strengthened. The multistage MBBR, MBBR and A / O, MBBR and A2 / O, MBBR and MBR combined processes all have their own merits. The selection and application of combined processes need to be considered in combination with the actual situation, so as to maximize the benefits and optimize the economy. The nitrogen removal effect and phosphorus removal effect of the combined process are stronger, the operation is more stable, and the pollutant treatment efficiency is higher, which can greatly reduce the production of biological sludge, and the reduced content of effluent nutrients will have great application value for a long time in the future.
