The MBR membrane bioreactor technology advantages

Under high MLSS and microfiltration membrane filtration, the effluent is stable and high quality. High volume load, short stay time, MBR process than traditional system is simple, covers an area of less completely replace the sedimentation tank, sand filter unit, covers an area of 30% less than traditional way, no sludge settling problem reaction pool MLSS concentration can reach more than 10000 mg/L, resistance to impact load ability strong, effective treatment of high concentration organic wastewater Under the microfiltration membrane filtration, separation effect is far superior to the traditional sedimentation tank and the sand filter processing units, such as good effluent water quality stability, suspended solids and turbidity is low, the general low pollution in municipal wastewater treatment, can be directly used as ZhongShuiDao water or on-site recycling water use for slow proliferation, interception of nitrifying bacteria growth and reproduction,Low waste sludge quantity is lower than the traditional activated sludge process, mud, long cycle, large elasticity of operation, biological membrane tube system belongs to the absolute filtration system and high MLSS, to overcome the large variability of wastewater of PLC control system design, operation and maintenance easy, it can realize automatic control, easy to manage high biological sludge concentration operation; MLSS = 6000 ~ 10000 mg/l, can reduce the volume of biological aerobic sludge pool Can make enclosed design, low pollution, low noise, low odor of macromolecular membrane separation has greatly increased the sewage of the refractory material processing efficiency standard mobile modularization design, quick and easy installation, easy installment expansion is suitable for the for the modification of old sewage treatment plant, only add the MBR membrane group equipment.
  The original program to join the MBR
The process change Two original program in sedimentation tank, fast, slow mixing pool, pool pressurized except, upflow filter a set, such as activated charcoal tower two programs. Can all be replaced by the MBR are almost. Put one pool tank instead of flat, in MBR module. Can replace the original other programs.
Dealing with water quality is better Originally to pressurized float in addition to discharge water quality after:
COD = 182 mg/l, SS = 6.5 mg/l,
NH4 - N = 0.4 mg/l, NO3 -- N = 31.4 mg/l water quality after the MBR treatment:
COD = 165.5 mg/l, SS = 5.7 mg/l,
NH4 - N = 0.19 mg/l, NO3 -- N = 25 mg/l
Operation and maintenance easier and cheaper Original program complex and numerous pool body with mechanical, technical personnel operation and high complexity. Manpower needs. After replaced by MBR pool, backwashing by PLC automatic control. Chemical cleaning program ? alone
