摘要
某制药集团公司对现有的污水处理设施进行升级改造,以达到新的出水水质标准,其主体生物处理工艺为“厌氧十好氧膜生物反应器”组合工艺。目前,废水处理站改造工作已基本完成。膜生物反应器(MBR)处理制药废水试验研究的目的是能够为建成后的污水处理站好氧膜生物反应器提供可靠的运行控制条件,包括生物系统控制参数(如污泥浓度、溶解氧、停留时间等)和膜组件性能参数(如运行周期、膜通量、反冲洗等)。膜生物处理器处理制药废水膜组件性能试验研究是膜生物反应器处理制药废水试验研究的一部分。
     本试验通过三组不同的膜生物反应器(PVDF微滤膜生物反应器、PVC超滤膜生物反应器、PVDF超滤膜生物反应器)处理某制药集团公司污水处理站的厌氧池出水,试验其处理效果,并分析膜生物反应器运行过程中的各项参数对膜污染的影响,还进行了MBR的运行周期试验,得到以下结论:
     (1)试验比较了三组膜生物反应器的出水效果,膜生物反应器的出水水质主要受生物系统影响。综合比较三组膜组件,PVC超滤膜组件较为适用于诺氟沙星制药废水的处理。
     (2)在膜污染影响因素试验研究中,通过对运行方式、温度、曝气量和生物系统操作条件的试验,得出膜生物反应器在间歇反冲洗运行方式、较高的水温和较高的曝气量下运行膜压差上升的缓慢。在长时间的试验实际操作过程中,随着运行时间的不断增长,膜通量会出现一定范围的下降,其中PVDF微滤膜的膜通量下降最为明显。
     (3)根据试验数据确定了三组膜生物反应器的运行反冲洗周期,即PVDF微滤膜的反冲洗周期为10d, PVC超滤膜的反冲洗周期为12d, PVDF超滤膜的反冲洗周期为14d。试验了PVC超滤膜和PVDF超滤膜化学维护周期,即PVC超滤膜每经过1-2次反冲洗后进行化学维护,PVDF超滤膜每经过2-3次反冲洗后进行化学维护。
A pharmaceutical company is upgrading the existing wastewater treatment station, in order to reach a new water quality standards. Its main biological treatment processes is the combined process of anaerobic and aerobic membrane bioreactor. At present, the wastewater treatment station renovation work has been almost completed. The purposes of this study, using membrane bioreactor to treat pharmaceutical Wastewater, is provide some reliable conditions to run and control MBR after the completion of the sewage treatment station renovation. The conditions include biological system control parameters (such as concentration of activated sludge; dissolved oxygen; hydraulic retention time etc.) and membrane module operational control parameters (such as operation cycle; membrane flux; backwash etc.). The study of membrane module performance on the treatment of pharmaceutical industry wastewater by using MBR is a part of the MBR test.
     In this test, the waste water comes from the company sewage treatment station anaerobic tank. Using three different groups of membrane bioreactor (PVDF microfiltration membrane bioreactor; PVC ultra-filtration membrane bioreactor; PVDF ultra-filtration membrane bioreactor) treat the wastewater, then emission the water. Study the effect of some parameter to membrane fouling when the MBR is running. And also take a operating cycle and backwash test. Through the test, we have these following conclusions.
     (1) The test compared the effluent effects of three groups of membrane bioreactor, the MBR effluent quality is related with the biological systems operate. Comprehensive comparison of three groups of membrane, the PVC Ultra-filtration MBR is more suitable for treating Norfloxacin pharmaceutical wastewater.
     (2) With the test of membrane fouling factors experimental study, and through the operation mode, temperature, aeration and biological systems operating conditions test, the results were obtained that with a intermittent backwashing operation mode, higher water temperatures and higher aeration rate can delay the trans-membrane pressure rise. In the long testing process, there will be a range decline of flux, and PVDF microfiltration membrane decreased is most obvious.
     (3) Determine the three membrane bioreactor run backwash cycle based on the test data. The backwash cycle of PVDF microfiltration membrane is10d, PVC ultra-filtration membrane is12d, and PVDF ultra-filtration membrane is14d. It also determine the chemical maintenance cycle of ultra-filtration membrane, PVC membrane after1to2backwash need a chemical maintenance and PVDF after2to3times.
