Effect of hydraulic conditions on treatment of polluted river water by hybrid constructed wetlands
摘要
Abstract
The effect of hydraulic conditions on the treatment of polluted river water by the hybrid vertical up-flow constructed wetlands was observed by controlling different hydraulic conditions, e.g. hydraulic loading rate and hydraulic retention time (HRT). The results of one year operation indicated that hydraulic conditions have significant effect on the removal efficiencies of other pollutants but total nitrogen. It could improve the removal efficiencies of TP, NH3-H and COD by extending the hydraulic retention time, and it was the same as the increasing of hydraulic loading rate, however, the removal rate of TN decreased slightly in this ease. Under the conditions of shorter HRT and higher hydraulic loading rate, it can achieve good performance for pollutants removal in this study, the concentrations of COD, NH3-N, and TP in the treated effluent could achieve "the Urban Sewage Treatment Plant Pollutant Discharge Class I Standard". Comprehensively considering the removal capability for pollutants and economic effect, suitable operation condition of the integrated constructed wetland in this study was suggested as: 1 d of hydraulic retention time, and 0.66 m3/(m2 · d) of hydraulic loading rate.关键词
