中文摘要 | 台灣地區由於污水下水道建置未臻完成,家庭生活污水未妥善收集與處理,排放量已逾 55%。環境保護署自2008 積極辦理推動淨化河川水質、促進社區發展及提升居民生活品質, 在適當地點,規劃建置人工溼地處理受污染的河川或社區生活污水。本研究以大林鎮三疊溪橋 下之明華人工濕地,探討其對生活汙水污染物之削減率。經分析各類水質參數,水質處理後pH 值略為提昇;惟pH 值之月變化不大。溶氧量除100 年2 月之測值無明顯改善外;其餘放流水 之測值均較進流水測值高。BOD 去除率之月變化雖大,但皆達設計目標(去除率50%)以上。 NH3-N 去除率之月變化亦大,其平均NH3-N 去除率約11%。SS 於98/7、98/10 及99/7,放流 水之SS 測值反而比進流水之測值為高,應為颱風季節,水生植物受風雨破壞, SS 因流水捲 揚而上升;其餘時段SS 之平均去除率約為26%。因氣象及水生植物生長狀況會影響明華人工 濕地淨化成效,NH3-N 及SS 去除率未達設計目標, 僅 BOD 有達到水質淨化效益與處理目標。 |
英文摘要 | Due to the construction of sewerage in Taiwan is not fully completed; the domestic wastewater is not well collected and treated. More than 55% of wastewater belongs to domestic wastewater. Environmental Protection Administration (EPA) has been strenously done on purifying river water, helping to develop communities, and raising residents’ life qualities since 2008. EPA had marked out several constructed wetlands in proper places and set them up to deal with those polluted rivers and domestic wastewater from communities. In this study, domestic wastewater from Sun-Dia brook in Da-lin town has been purified through Min Hua constructed wetland. The water pH is slightlyincreased after treatment, and the dissolved oxygen of effluents except in Feb. 2011 were higher than those of the intake water. Although monthly changes in removal of BOD was huge, they were higher than 50%, and all of them reached the designed goals. Monthly changes in removal of NH3-N were also huge, and the average removal rate was about 11%. The SS of effluents were higher than those of the intake water in Jul. 2009, Oct. 2009, and Jul. 2010 due to the aquatic plants might be damaged by wind and torrential rain during the typhoon seasons, the average removal rates of SS was about 26% calculated from the data except the months mention above. Because climate and the aquatic plant growth conditions can both influence the water-purification, the removal rates of NH3-N and SS didn’t achieve the designed goals. Only the BOD removal rate achieved the goal of purification and treatment. |
