摘要 介绍了废水厌氧处理系统中微量金属营养元素生物有效度的概念,分析了影响微量金属营养元素生物有效度的诸多因素。厌氧生物处理系统存在微量金属营养元素并不等于存在微量金属营养元素生物有效度;对厌氧生物处理系统进行微量金属营养元素生物有效度的检定是非常必要的;微生物的螯合作用对微量金属营养元素生物有效度起非常重要的作用;微量金属营养元素必须直接加入反应器内才能充分保证其生物有效度。 The concept of bioavailabiblity of trace metals in anaerobic wastewater treatment system is introduced and the factors affecting the bioavailability are analyzed.The presence of trace metals is not equal to the bioavailability of trace metals in the system.It is necessary to determine the bioavailability of trace metals in the system.Biochelation plays an important role in the bioavailability of trace metals.Trace metals must be supplemented directly into anaerobic reactor for keeping their bioavalability.
