【摘要】 以上海城区黑臭河水的生物-生态处理工艺为研究对象,采用灰色理论分析水生植物在黑臭河水治理过程中的生理响应顺序,为科学解释污染物净化机制提供依据.结果显示,植物的生理特性对COD和NH4+-N去除的优先级关联排序均为POD>CAT>Chla>SP>Chlb,表明反应体系对黑臭河水中COD和NH4+-N的去除主要是通过微生物降解和转化途径.但是,植物的生理特性对TP去除的优先级关联排序为Chlb>SP>Chla>CAT>POD,表明反应体系对黑臭河水中P的去除则主要是通过水生植物的吸收作用.更多还原

【Abstract】 The grey relational analysis was initiated to investigate the relationships between the physiological properties of aquatic plants and the performances of the bio-eco-technology for the treatment of malodorous rivers in Shanghai.The main objective of this research was to provide scientific explanation for the water purification mechanisms of the bio-eco-technology.The results indicated that the priority response order of the plants physiological properties for COD and NH+4-N removal was POD>CAT>Chla>SP>Chlb,indicating that the microbial degradation could be mainly responsible for the removal of COD and NH+4-N.However,the priority associated grade of the plant physiological characteristic for TP removal was Chlb>SP>Chla>CAT>POD,demonstrating that the adsorption of aquatic plants played a dominant role in removing total phosphrous from malodorous black water.更多还原
