| 摘要: | 以人工溼地系統處理廢水為一自然淨化程序，在淨化水質過程中，不需添加任何化學藥劑，且操作、維護簡單，應用於污染物質單純之校園污水的處理，具有言午多優點，系統中有會存在言午多的生物物種，有如一個小型生態系統，除具備廢污水處理及再利用?能外，更具教育功能本研究主要是以三個不同校園溼地系統之差異，以其等對各項污染物之去除效能做比較分析。結果指出，對各項污染物之去除效率分別為：嘉南藥理科技大學小型人工溼地模場之生化需氧量(BOD)及化學需氧量(COD)之去除率為55.7%及62.1%、氨氮(NH4-N)及正磷酸鹽(PO4-P)之去除率為36.8%及36.7%、大腸桿菌(E.coli)及總懸浮固體物(TSS)之平均去除率為96.4%及69.9%；光華女中人工溼地暨景觀池之BOD及COD之去除率為66.3%及40.3%、NH4-N之去除率為39.08%、E.coli及TSS之平均去除率為87.10%及1.64%；國立成奶j學建築系人工溼地系統之BOD及COD之去除率為79.9%及63.3%、NH4-N及PO4-P之去除率為53.3%及59.6%、E.coli及TSS之平均去除率為100%及86.7%。最後，利用三個校園溼地系統之構築及污水性質的差異，討論校園污水經處理後之循環再利用性及其功能性
The wastewater treatment using the constructed wetland (CW) system is one natural purifying process. There are many advantages for the method of CW is used to treat the wastewater in the campus. For example, its operation and maintenance are simple, and it is not necessary to adding any chemicals during the proceeding.In this study, three different types of CW system in different campus were used to treat the campus wastewater and discussed by the treatment efficiencies. The results showed that, the average removal efficiency of BOD5, COD, NH4-N, PO4-P, E.col i, and TSS for the pilot-scale CW system in Chia Nan University of Pharmacy and Science were 55.7%, 62.1%, 36.8%, 36.7%, 96.4%, and 69.9%, respectively. The average removal efficiency of BOD5, COD, NH4-N, E.coli, and TSS for the CW system in Kuang Hua Girls’ Senior High School were 74.8%, 6.9%, 53.3%, 98.9%, and9.17%, respectively. And for the CW in National Cheng Kung University, the average removal efficiency of BOD5, COD, NH4-N, PO4-P, E.coli, and TSS were 79.9%, 63.3%, 53.3%, 59.6%, 100%, and 86.7%, respectively. The different efficiencies for three CW systems were also discussed by the different constructs and wastewater characters. |
