          【MBR工艺】

                

               - 生物反应器工艺(Membr  ane  Bio-Reactor,简称MBR)是膜分离技术与生物技术有机构成之新星废水处理技术。其它应用膜分离设备将生化反应池中的活性污泥和大分子有机物质截留住,节约二沉池及不需三级处理过程。结构性污泥浓度因此大大加强,电力停留时间(HRT)和污泥停留时间(SRT)可以分别控制,而艰难降解的现实在新石器中不断反应、降解。因而,膜 - 生物反应器工艺通过膜分离技术大大强化了生物反应器的力量。与民俗的古生物处理办法相比,具有生化效率高、抗负荷冲击能力强、出水水质稳定、占地面积小、彩排泥周期长、易实现自动控制等优点,是现阶段最有前途的废气处理新技术之一。

           

                MBR的亮点

              1、迅速地展开固液分离,她分离效果远好于传统的沉淀池,出水水质良好,出水悬浮物和浊度接近于零,可直接回用,贯彻了活水资源化。 
              2、膜的迅猛截留作用,使微生物完全截留在生物反应器内,贯彻反应器水力停留时间(HRT)和污泥龄(SRT)的完整分离,运作控制灵活稳定。 
              3、鉴于MBR名将传统污水处理的曝气池与二沉池合二为一,并取代了三级处理的任何工艺设备,因而可大幅削减占地面积,节约土建投资。   
              4、利于硝化细菌的遏止和繁殖,系统硝化效率高。穿越运行方式的改观亦可有脱氨和除磷功能。   
              5、鉴于泥龄得以非常长,因而大大加强难降解有机物的降解效率。
              6、玉器在高容积负荷、低污泥负荷、长泥龄下运作,剩下污泥产量极低,鉴于泥龄可无限长,理论上可实现零污泥排放。
              7、系统实现PLC控制,借鉴管理方便。

                                               MBR process

             Membrane bioreactor process (Membr ane Bio-Reactor, referred to as MBR) is a new wastewater treatment technology and the organic combination of membrane separation technology and biological technology. It will be the pool of activated sludge biochemical reactions andmacromolecular organic matter trapped by the membrane separation equipment, saves two sedimentation tank and does not need to be level three process. Activated sludge concentration thus greatly improved, hydraulic retention time (HRT) and sludge retention time (SRT) can be controlled separately, while the refractory material continuous reaction, degradation in the reactor.Therefore, the membrane bioreactor process through the membrane separation technology has greatly enhanced the function of bioreactor. Compared with the traditional biological treatment method, has high purification efficiency, anti shock loading ability is strong, stable water quality of effluent, small occupation area, mud cycle is long, easy to realize automatic control and other advantages, is one of the new wastewater treatment technology is currently the most promising.

                The advantages of MBR:

            one, efficient solid-liquid separation, the separation effect is far better than the conventional sedimentation tanks, good quality of effluent, the effluent suspended solids and turbidity are close to zero, can be reused directly, realize the sewage resources.

                two, retention function of membrane, the microbial completely retained in the bioreactor, realize thereactor hydraulic retention time (HRT) and sludge age (SRT) are completely separated, flexible control stability.

                there, because the MBR will be the traditional sewage treatment aeration tank and two sedimentation tank Become, and replaces the three stage treatment of all process facilities, thus can greatly reduce the occupied area, save construction investment.

               four, in favor of nitrifying bacteria and nitrification efficiency of interception breeding, high. Through the change of operation mode can also be off the ammonia and phosphorus removal function.

               five, because the sludge age can be very long, thus greatly improving the efficiency of refractoryorganic matter degradation.

              six, the reactor operated at high volume load, low sludge load, long sludge age, excess sludge yield is very low, because the sludge age can be infinitely long, in theory, can realize zero discharge of sludge.

              seven, the realization of PLC control system, convenient operation and management.

             

             The scope of application

             one, in the small town, wastewater treatment and reuse;

             two, domestic sewage, car washing wastewater treatment and reuse;

             there, the high concentration organic wastewater treatment and reuse;

             four.The treatment and reuse of organic wastewater, printing and dyeing 

              pharmaceutical,slaughter wastewater etc.
