微氧水解强化复合型人工湿地中试反应器的性能研究

     

摘要

Two pilot-scale facilities combined with a micro-aerobic hydrolysis functional section and a horizontal subsurface flow (HSF) constructed wetland cell were established for investigation of the performance of pollutant removal from malodorous black water.In this paper,such two kinds of plants were introduced as Alteruifolius and Calamus.The reactors were performed at a loading rate of 0.2 m3 (m2.d)-1.The results showed that the CW planted with Alternifolius (system A) was slight better than that planted with Calamus (system C) in the contaminant removal.The mean removal efficiencies of system A were 69.65% for COD,75.2% for BOD5,58.33% for TN,38.46% for NH4+-N,59.8% for TP and 82.1% for TSS.The data indicated that micro-aerobic hydrolysis established high degradation efficiency of TSS and therefore enhanced the infiltration capacity of porous and prevented media from clogging.Data analysis showed that there was a correlation between the removal ratio of COD,NH4+-N and TN and DO concentrations and temperature in the effluent.%考察两组微氧水解强化复合型人工湿地(MA-HCW)组合的中试反应器,对城市黑臭水体的净化处理效果.两组反应器分别种植风车草和菖蒲两种植物,运行的水力负荷为0.2 m3/ (rn2·d).结果表明,种植风车草的人工湿地系统(A系统)的总体净化效果略优于种植菖蒲的人工湿地系统(C系统).A系统的COD、BOD5、TN、NH4+-N、TP、TSS平均去除率分别为69.65%、75.2%、58.33%、38.46%、59.8%、82.1%.研究表明,微氧水解功能段有效降低了进水中TSS的浓度,起到预防湿地系统堵塞的作用.数据分析显示COD、NH4+-N和TN的去除率与溶解氧和温度有相关性.
