当前，我国水环境问题突出，治理形势严峻。国务院强化了节能减排政策的实施力度，许多敏感地区将强制实施国家一级A甚至更高的排放标准。
强化脱氮除磷膜生物反应器工艺（3AMBR），可以将高浓度有机污水一次处理成超一级A标准的优质再生水，在完全达到国家一级A标准的同时，还可进一步重复利用，实现节约水资源的目标。这一技术的成功开发和应用对解决我国水污染控制和水资源短缺双重难点带来信心和希望。
3AMBR，即Anoxic-Anaerobic-Anoxic Membrane Bio-Reactor，是根据生物脱氮除磷机理，结合膜生物反应器技术特点而形成的具有高效脱氮除磷性能的新型污水处理工艺。其基本原理是，膜生物反应器内高浓度硝化液和高浓度活性污泥经过智能回流系统形成良好缺氧、厌氧条件，实现系统的高效脱氮除磷。
3AMBR工艺具有如下九个特点。首先，出水水质标准高，品质稳定，超过国家一级A标准，出水COD小于30，BOD小于5，氨氮小于2，悬浮物和浊度接近于零。其次，占地面积小。3AMBR工艺占地面积只有传统工艺的1/3~1/2。另外，对水质变化适应力强，耐冲击负荷高。膜生物反应器MLSS浓度高，达到8000~12000mg/L，大大提高了系统对水质变化的抗冲击性。再有，污泥产量少，由于系统MLSS浓度高，污泥产率系数比传统方法小1/4~1/3。
3AMBR具有突出的脱氮性能，脱氮率可达80%以上。3AMBR 工艺实现了SRT与HRT完全分离，有利于增殖缓慢的硝化细菌的截留、生长和繁殖，系统硝化效率高；MLSS浓度高，反硝化基质利用速率高。3AMBR还具有突出的生物除磷性能，除磷率可达80%以上。3AMBR 工艺实现了好氧排泥，没有磷的释放；膜的完全截留作用，出水SS接近于零，SS中的磷被彻底截留。因此，污泥含磷率高，是传统方法的1.2~1.5倍。
另外，3AMBR易于旧厂改造升级。在传统工艺基础上改造升级，在保证更高出水标准的前提下，可使原系统实现水量扩容50%以上。
3AMBR模块化设计，工艺设备相对集中，易于实现自动化控制，智能化管理。
技术经济性较好是3AMBR的第九个特点。对于新建的污水处理厂（万吨以上），3AMBR工艺的吨水投资成本为1500~2000元，与同水质传统工艺相当；直接运行费用为0.5~0.65元/吨，较传统三段工艺低。
3AMBR是目前世界上最先进的污水资源化工艺，代表了污水处理的方向。目前，该技术已实现了大规模工程应用，并取得了令人满意的效果。这些工程包括：北京密云再生水厂（4.5万吨/天）、怀北污水处理厂（5000吨/天）、怀柔再生水厂（3.5万吨/天）。
3AMBR技术是北京碧水源科技股份有限公司研究开发的专利技术。北京碧水源科技股份有限公司是世界上最大的MBR系统装备制造供应商之一。

The Apex System, added to existing activated sludge systems, increases the effective Mixed Liquor Suspended Solids (MLSS) inventory of the system without increasing solids loading to the clarifier. This economical, easy-to-install system upgrades a wastewater treatment facility without increasing tankage. The Apex system requires no additional maintenance and installs with little or no disruption to plant operations.
Increased Capacity
The flexible, high-surface-area media is submerged in the activated sludge tanks to provide extensive surface area for biomass growth. The attached biomass population can increase the effective MLSS concentration by over 3000-4000 mg/l, increasing organic load capacity. This also reduces F/M ratios, improving process control and stability
Higher MLSS Without Higher Clarifier Solids Loading
Because a significant portion of the active biomass remains attached to the Apex rather than suspended in the mixed liquor, organic removal increases without overloading secondary clarifiers with higher solids loads. For activated sludge systems with clarifier solids loading problems, treatment performance can be maintained or even improved while reducing MLSS loading to the secondary clarifier.
Resistant to Organic and Hydraulic Shock Loads
An “Achilles Heel” of activated sludge technology is the potential for peak hydraulic surges to “wash out” the suspended biomass from the aeration basins. With Apex, a significant amount of biomass is fixed in place and is available to treat the incoming organic load that accompanies hydraulic surges
Enhanced Nitrification
The biomass living on the Apex media increases MCRT (Sludge Age), promoting nitrification. During cold weather and where lower compliance limits are imposed, the added biomass improves the performance of nitrifying plants, or even allows non-nitrifying plants to nitrify.
Active Media Surface
Apex media has a tensile strength in excess of 1000 lbs. per lineal foot, yet is flexible enough to move like “reeds in a stream.” This movement creates localized turbulence that constantly renews surface areas and promotes oxygen transfer.
The total surface area available for biomass attachment at startup is up to 800 sq. ft. per cubic foot of installed media module. However, dry surface area does not tell the whole story. From those 800 sq. ft. of attachment points, the biomass grows underwater in 3 dimensions, creating flexible “branches” of non-blinding active surface area that can be measured in pounds per cubic foot, while still allowing for free flow of oxygenated wastewater through the media.
Economical
By improving wastewater treatment without adding aeration tankage or clarifiers, the Apex System is a low-cost solution to upgrading activated sludge plants.
Easy to Install
The entire Apex system can be installed without dewatering the aeration basin or modifying the aeration diffusers. The custom-sized/constructed Apex modules are lowered into the aeration basin with a crane and supported by the tank walls or on legs above the tank floor.
Durable and Long-Lasting
Apex is designed for durability and long life under the harsh conditions of an activated sludge aeration tank. The Apex media uses high-strength polyester. Even if a strand is cut or broken, the fabric will not fray or unravel.
