Gongye shui chuli, 2005 采用曝气生物滤池工艺对燕化公司西区污水处理场的二级出水进行了处理，研究了进水NH3-N浓度、COD浓度、m(COD)∶m(NH3-N)、碱度及气水比对NH3-N去除效果的影响。试验结果表明，当进水NH3-N质量浓度小于30mg/L时，曝气生物滤池对NH3-N具有良好的去除作用，平均NH3-N去除率达到90.4%，出水NH3-N质量浓度可降至1mg/L以下。NH3-N去除率随进水m(COD)∶m(NH3-N)的增加而降低；当进水m(COD)∶m(NH3-N)小于2.0时，NH3-N去除率达到90%以上 ...

Advanced Materials Technologies, EarlyView.A multi‐point oxygen‐sensing ultra‐fine needle (MO‐UFN) is developed by conformally integrating a lithographically patterned flexible electrochemical sensor array onto a clinical acupuncture needle. The platform preserves an approximately 0.3 mm diameter while enabling spatially resolved oxygen profiling along the insertion pathway.
