摘要

Natural treatment systems are gaining preference as a wastewater treatment option since it is a form of ecosystem-based adaptation to climate change. The study investigated the performance of a laboratory scale horizontal, subsurface flow constructed wetland (SSFCW)planted with cogon grass (Imperata cylindrica)in reducing the pollutant concentration of slaughterhouse wastewater in Zamboanga City, Philippines. Results showed that the mean efficiency of BOD_5 removal at seven (7)and 14 days detention time were 94.49 percent and 89.31 percent, respectively; while the average TSS removal efficiency were 97.8 percent and 99.9 percent, respectively. Statistical analysis of the BOD_5 removal efficiencies revealed significant difference; which means that higher BOD_5 removal is achieved at seven (7)days detention time. Analysis of the TSS removal efficiencies likewise revealed a significant difference, proving that longer detention time results in higher suspended solids removal. Therefore horizontal, SSFCW planted with cogon grass can be used to treat slaughterhouse wastewater at seven (7)days detention time. A pilot study is recommended to validate laboratory-scale finding. Future reseach should also investigate the performance of horizontal, SSFCW using other wastewater sources, different parameters, other endemic hydrophytic grasses, and to consider meteorological and climatological factors.
