AB  - Two groups of integrated vertical-flow constructed wetland (IVCW) microcosms were 
      established for treating two types of representative wastewater: domestic and 
      nitrified wastewater under two loading rates (LRs) over about two years. Their 
      removal capacities of organic substance and nitrogen as well as the effects of 
      loading rate (LR), outflow temperature and dissolved oxygen (DO) concentration 
      were investigated and compared. Efficient chemical oxygen demand (COD) 
      eliminations were achieved by the IVCWs, with the mass removal rates increasing 
      linearly with the increasing LRs strongly, achieving average value of 56.07 g 
      m(-2) d(-1) at the highest loading rate. Nevertheless, the effluent COD 
      concentrations also increased, with the average value exceeding Class I A 
      discharge standard (< 50 mg L(-1)) for municipal wastewater treatment plants in 
      China at the highest loading rate. Greater total nitrogen (TN) mass removal rates 
      but lower efficiencies were obtained at the high LR for both types of wastewater, 
      and better removal was achieved for nitrified wastewater (NW) in comparison to 
      domestic wastewater (DW), probably due to the prevailing anoxic conditions inside 
      the IVCW beds restricted nitrification process of DW. The influences of LR, 
      temperature and DO on COD removal were slight, but all remarkable on TN 
      reduction. As compared to DO, temperature was more crucial for nitrogen removal, 
      and the temperature dependence coefficient for TN removal of low LR of NW was 
      significantly greater than others.
