中文摘要 | 摘 要 近年,隨著氣候變遷與全球暖化議題,在國際間「省能源、省資源」的社會低碳 經濟與低碳社會的新趨勢已經悄然形成。本研究係針對綠色永續的校園推動雨水貯 留、污水處理後水資源回收再利用,藉由節約能源、節水、省電、減碳過程之相關分 析結果,進行雨水貯留、污水回收處理後等水資源再利用,探討可節省用水量、用電 量,並推估可能削減CO2排放量。 深坑國中經多次現場踏勘,得知深坑國中校園師生總共727人,年降雨量約3,288 m3,全年潛在雨水量約6,274 m3,洗手台用水量為1.87 m3/d,廁所用水量為5.33 m3/d。 依據深坑國中95年度各月自來水水費單資料,並以每月上課22日計算,推估每月所使 用水量來換算二氧化碳當量,深坑國中全年用水量為5,609度,為安全考慮,其中40% 為用於廁所沖洗,而替代率以90%計算,故整年可節省自來水量為5,609 × 0.9 × 0.4 = 2,019度。 由於,雨污水回收淨kgCO2e/年削減量等於雨污水回收削減CO2量-處理回收再利 用所需增加CO2量。因此,若水費每度以16.5元計算,推算將可節省水費為16.5 × 2,019 = 33,314元,扣除操作費用1,617元,每年可節省用水費33,314 - 1,617 = 31,697元。同 時,若用水每度可排放1,161kg CO2時,雨污水回收資源再利用將只需使用2,321度用水 量。整年抽水量約為3288 m3,過濾機每半年反洗一次。用電度數估算為1,029度,二氧 化碳排放656 kgCO2e/年。因此,校園雨污水回收再利用措施,不但可以節省用水費及 電費,可節省相當可觀的經費之外,同時亦能達到CO2排放削減之最終目的。 |
英文摘要 | Abstract To give an impetus to recycle and reuse water resource for setting up rainwater store system at some sustainable green campus in Taiwan. In rainwater store system of Shen-Kun Junior high school, the economizing the use of water quantity, the supply of electric power and the possibility reduction of carbon dioxide emission were evaluated. The average yearly precipitation, the yearly latent rainwater, water quantity of washbowl and lavatory were 3,288 m3, 6,274 m3, 1.87 m3/d, and 5.33 m3/d, respectively. The days for average monthly conduct a class are 22 days, and the yearly water quantity of Shen-Kun Junior high school was 5,609 m3. To estimate the ratio of substitution and reuse rainfall resource for water quantity of lavatory is 90% and 40 %, respectively. The economizing the use of yearly water quantity of tap-water is 5,609 × 0.9 × 0.4 = 2,019 m3. Exactly, the net yearly reduction carbon dioxide emission of recycle and reuse of rainwater and sanitary sewer are the diversity between the yearly reduction carbon dioxide emission by recycle and reuse of rainwater and sanitary sewer and the yearly increase carbon dioxide emission for rainwater and sanitary sewer recycle and reuse treatment processes. If the fees of tap-water is 16.5 NT dollars per m3, and 33,314 NT dollars of the charge of water quantity can be economized. Furthermore, 656 kgCO2e of carbon dioxide emission should be reduced in low carbon emission campus of Shen-Kun Junior high school. |
