碩士 / 國立臺灣大學 / 生物環境系統工程學研究所 / 100 / This study explored Xinhai artificial wetland, biological oxygen demand concentration on long-term treatment results. A basic test data, perform regression analysis to understand the biological oxygen demand concentration removed rate and development time, maintenance jobs, concentration, flow rate correlation.Assessment of artificial wetland system, effectiveness of urban wastewater treatment, as our reference in constructed wetland for long-term maintenance operations.
Long-term average removal rate for biological oxygen demand concentration 68.73 ± 19.63％, but long-term concentration removed rate will decline because of build time increased, estimated about 29 years to build complete, removing low efficiency will be 40%. Maintenance of constructed wetlands have significant effects on treatment effectiveness, maintenance definition, is a wetland and the operation and maintenance of mechanical and electrical equipment for regular. Maintenance period the average removal rate 81.68 ± 6.32%, does not maintain a period average removed rate of 49.6 ± 16.85%. Average removed rate of maintenance period, About 1.65 times that is not the maintenance period times, the result is the difference. Long-term maintenance job description, can remove rates improve concentration. But also human and climate impact.
