- Abstract:
- The effect of a combined process of aeration pond and constructed wetland on the treatment of rural sewage was explored in Guanshan Constructed Wetland, Taidong County, Taiwan Province. From August 2008 to December 2018, a total of 125 groups of data were collected through the data collection for once a month. The removal efficiencies of BOD5, SS, NH4+-N, TN and TP by the constructed wetland system were (61.55±16.71)%, (63.39±11.18)%, (82.21±12.11)%, (67.88±13.89)% and (71.31±12.31)%, respectively, and the average surface pollutant loading rates of BOD5,SS,NH4+-N,TN and TP were (1.23±0.52) g/(m2·d), (2.62±2.36) g/(m2·d), (1.98±0.34) g/(m2·d), (1.78±1.01) g/(m2·d) and (0.13±0.05) g/(m2·d), respectively. The process operated stably with a good treatment performance, and the effluent quality met the requirements of relevant water quality standards of Taiwan Province. The whole system was combined with the ecological landscape to build a hydrophilic environment, and showed good environmental benefits.
