【摘要】 剖析了常见的高负荷厌氧氨氧化反应器的构型特点,归纳了颗粒污泥反应器(上流式厌氧污泥床、膨胀颗粒污泥床和气提式反应器)、生物膜反应器和复合式反应器的优缺点。系统总结了高负荷厌氧氨氧化反应器的调控要点,包括操作条件(负荷、回流等)调控、环境条件(pH值、温度、溶解氧等)调控、营养物质(基质比、钙离子浓度、无机碳源等)调控、抑制剂调控和微生物(接种源、优势种、聚集体、生物量和活性等)调控。最后指出,实现高负荷厌氧氨氧化反应器全面应用的关键是突破复杂水质障碍和在低温条件下进行有效调控。更多还原

【Abstract】 This study analyzed the configuration of some common high-loaded ANAMMOX reactors,and dissected merit and demerit of granular sludge bed reactors,including Granular sludge reactors(upflow anaerobic sludge bed,expanded granular sludge bed and gas-lift reactor),biofilm reactors and hybrid anammox reactors.This paper also summarized detailed process control regulations,including operating conditions(load,reflux),environmental factors(pH,temperature,dissolved oxygen and so on),nutrients(the ratio of substrate,the concentration of Ca2+,inorganic carbon) inhibitors and microorganism(the source of sludge,dominant species,aggregation,biomass and the activity).The key factor of extensive application of the high-loaded ANAMMOX reactors is overcoming the barrier of complex wastewater and regulating reaction conditions at low ambient temperature.更多还原
