論文摘要內容:
行政院農業委員會為發展農業科技，依「農業科技園區設置管理條例」而設置屏東農業生物科技園區，本園區屬於開發行為應實施環境影響評估者，為了落實各項環保對質及檢討執行，污染總量之控制進行適當的管制措施以避免開發及營運過程中各項環境衝擊超出原預估範圍。

本研究旨在探討於園區內事業排放廢水，因各進駐廠商所排放之廢水性質有所不同，因此在廢(污)水排入下水道前系統之前須符合園區水質納管標準，避免排入下水道差異過大而造成污水廠處理之負擔。本研究以園區內所有事業為調查對象，將園區廠商分為四大行業別分別為食品製造業、化工業、養殖業、其他行業，以不定時、不定期之方式為期一年每個月份各採樣一次，採樣位置於各事業廠商排放廢(污)水至下水道前之放流口，採樣項目為SS、COD、pH、水溫，樣品則是以環保署公告之檢驗方式進行檢驗分析並取得數據。

依據各行業別污水排放量及不符合納管標準之超標次數及超標比例調查結果得知食品製藥業為園區高污染之產業，其廢水中之COD依據檢測結果超標比例為11.6%且污水排放量為1803.6CMD為全園區佔比最高之排水量，從上述調查結果可以得知此原因為造成污水廠進流水不穩定之主因，作為園區內行業別家數最多且排放廢水量最高之產業，可針對此行業別在未來廠商進駐前就以源頭減量及前處理設施建置建議之方式進行輔導，下水道系統管理為園區最重要環保基礎建設之一，攸關園區是否可以妥善處理收集園區內之廢水，因此在對事業廢水之特性掌握相對極為重要，本研究調查之結果及數據資料也可供未來園區污水廠操作或是擴建之參考。

To develop agricultural technology, the Council of Agriculture, Executive Yuan, founded the Pingtung Agricultural Biotechnology Park, according to the Act of the Establishment and Administration of Agricultural Technology Parks. The development of this park required an environmental impact assessment. To ensure a high level of environmental protection, the total amount of pollution must be controlled to avoid exceeding the expected level of negative environmental impact during the park’s development and operation processes.

This study aimed to explore the wastewater discharge by businesses and manufacturers in the park. The nature of wastewater discharged by various businesses and manufacturers varied. Therefore, before being discharged into the sewer system, the wastewater must meet the influent water quality standards of the park to avoid increasing the burden on the wastewater treatment plant because of different types of wastewater discharged into the sewer system. This study targeted all businesses and manufacturers in the park, which were divided into four types: food manufacturing, chemical industry, aquaculture, and others. Wastewater samples were collected from these four types of businesses or manufacturers at irregular intervals once per month over the course of a year. The sampling locations were the wastewater discharge outlets of various businesses and manufacturers before their wastewater was discharged into the sewer system. The sampling items included suspended solids, chemical oxygen demand (COD), pH value, and water temperature. The samples were analyzed according to the testing methods also used by the Environmental Protection Administration, Executive Yuan, Taiwan.

By investigating the amount of wastewater discharged from various businesses and comparing the frequency and proportion of the discharged wastewater with the influent water quality standards, the results showed that the food and pharmaceutical industry in the park is a highly polluting industry, whose wastewater COD of 11.6% exceeded the influent standards; in addition, the industry exhibited 1803.6 CMD of wastewater discharge, accounting for the highest wastewater discharge level in the park. According to these results, it can be inferred that this was a reason why the influent water of the wastewater treatment plant was unstable. The food and pharmaceutical industry comprised the highest number of businesses and discharged the largest amount of wastewater. These types of businesses should, therefore, be provided with guidance on how to reduce their wastewater levels when they enter the park, as well as on how to set up wastewater pretreatment facilities. The sewer system is one of the most fundamental infrastructures for environmental protection and is key to whether the wastewater in the park can be properly treated and collected. Therefore, the properties of industrial wastewater must be better understood. The results of this study can serve as a reference for the operation or expansion of the wastewater treatment plant in the park.
