【摘要】 在活性污泥废水处理系统中,合成有机化合物(synthetic organic compounds,简称SOCs)的去除受生物降解、吸附、挥发等因素的影响。在完全混合式反应器中,其出水浓度由降解动力学参数决定,挥发和吸附受污泥浓度的影响。因此,生物降解动力学可用来定量描述这类化合物的生物降解特性。本文综述了合成有机化合物在天然和人工水环境中的生物降解特性及各种影响因素。
【Abstract】 In activated sludge wastewater treatment systems,the removal of synthetic organic compounds (SOCs)was affected by biodegradation,adsorption and volatilization.Their effluent concentrations were determined by the kinetics of their biodegradation in a completely mixed bioreactor.Therefore,biodegradation kinetics can be used to quantitatively describe the biodegradability of these kinds of compounds.This paper reviewed the biodegradation of SOCs in natural and engineered environment.
