摘要 屏東縣為台灣地區之農業、畜牧及養殖業重鎮，生產過程中產生之農、牧、養殖廢水，加上工業、家庭污水及非點源污染，如未妥善處理而排入承受水體，將造成屏東縣內河川水質惡化，影響水體用途，因此，保護水資源及尋求有效之水污染管理及防治措施，為重要環境課題。轄內列管事業約1,970家，主要列管事業包含畜牧業、食品業、醫院等20餘種行業，其中畜牧業居冠約1,344家，占全縣68%，特擬定本計畫協助環保局加強東港溪事業水污染源偷排及暗管查核作業，並全面執行東港溪流域事業單位稽查及放流水質採樣檢測作業，利用輔導及告發等並行方式，以改善流域內事業單位違法行為，減少污染對環境之負荷，提升整體環境品質。 本計畫執行期程係由111年1月1日起執行至111年12月31日為止，惟工作項目需於111年11月30日前完成，工作項目及執行成果統計至111年11月30日，摘要如下: 一、東港溪流域及鄰近鄉鎮事業稽查 (一)本計畫已完成事業稽查累計988家次，包含畜牧業非草食性動物745家次、草食性動物37家次及非畜牧業之其他事業206家次，共查獲4家次重大違規(繞流排放)，分別為非草食性動物(豬)畜牧業2家次、草食性動物(牛)畜牧業1家次及「廢棄物焚化廠」或其他廢棄物處理廠(場)1家次。 (二)根據稽查結果顯示東港溪流域630家畜牧業，有249家廢水處理設施之厭氣池設有不鏽鋼加蓋或密閉式水泥槽體或設有紅泥沼氣袋，厭氣池加蓋比例由110年之23.5%提升至39.5%(111年)，自109至111年期間共計72家畜牧場興建厭氣槽體，提升水力停留時間；另外稽查過程中有48家畜牧業周界有明顯異味產生，本計畫透過橫向聯繫將異味名單提送環保局，經由空污科輔導業者改善異味。 二、水質採樣檢測作業 本計畫完成事業放流水採樣作業共156家次，分別採集不同行業別之事業(不含畜牧業)71家次，不合格率約7%；非草食性動物之放流水採集75家次，不合格率約44%；草食性動物放流水採集10家次，不合格率約100%，由此顯示，畜牧業廢水為東港溪流域的主要污染貢獻來源；事業5家次放流 屏東縣政府環境保護局 摘-2 水檢驗不合格，行業別為 3家次醫院、醫事機構及2家次屠宰業。 三、廢水設施深度查核作業 本計畫已完成6家次深度查核，查核對象分別是王○牧場、永○冷○食○工業股份有限公司潮州廠、萬○香○園股份有限公司屏東廠、強○冷○食品股份有限公司二廠、坤○有限公司附設屠宰場及旻○畜牧場等6家次，經現場委員查核結果顯示設施管線標示不清、廢水流程設計欠缺考量、活性污泥過多或參數推估有誤、污泥量異常及與現有許可證不符，後續將依委員建議，追蹤業者改善進度，以達到廢水處理功能最佳狀態。 四、污染即時監測查緝 本計畫稽查時發現疑似違規偷排事業及廢水設備不佳且多次巡查放流水未排放者，透過運用24小時污染即時監測設備架設監測，提升查獲效率同時減少稽查員長時間埋伏，其查獲事業違規成果豐碩，分別5家次非放流口排放廢水、14家次放流水檢驗不合格，1家次為水污染管制區排放廢水。 五、非列管事業污染源資料建置 (一)彙整東港溪流域非列管事業共計622家次，其中養鴨場最多256家，其次為養雞場249家，養鵝場54家，養羊場46家、養鹿場2家，及食品工廠15家等，已完成更新建置畜牧業非列管地圖與數量規模資料。 (二)本計畫已完成29家次非列管事業查核，分別是25家次非列管畜牧業(蛋鴨場)及4家次非列管事業(食品廠)並加裝流量計監測每日廢水量；另採集非列管事業放流水進行分析對東港溪流域污染負荷，蛋鴨場SS濃度介於76~4,000 mg/L、每日污染量平均28.4 Kg/d，COD濃度介於349~7,370 mg/L、每日污染量平均35.7 Kg/d，氨氮濃度介於21.3~295 mg/L，結果顯示，水質污染物濃度高低落差甚大，設有廢水處理設施之蛋鴨場，所排放之放流水相較於未處理直接排放濃度明顯較低；食品廠分為豆干工廠、豆皮工廠及畜牧內臟工廠，豆干工廠SS為1,620 mg/L、COD為4,450 mg/L；豆皮工廠BOD為2,060 mg/L、COD為919 mg/L；畜牧內臟工廠SS為88 mg/L、COD為213 mg/L，計畫結果顯示非列管事業排放之廢水對於東港溪流域污染負荷有所貢獻。 屏東縣政府環境保護局 摘-3 六、配合屏東縣政府環境保護局執行夜鷹早鳥及擴大稽查 本計畫協助環保局夜鷹早鳥及擴大稽查行動，共計出勤44場次，查核204家次畜牧業，查獲14家次有違規情事，違反水污染防治法第7條(放流水未符合標準)共計13家次、水污染防治法第28條共計1家次，裁處金額共計306,672元。

Abstract Pingtung is the stronghold of agriculture, husbandry, and aquaculture in Taiwan. With wastewater produced from these three industries and manufacturing industry, domestic sewage, and nonpoint source pollution, the water quality of rivers in Pingtung County area will decline and influence the functions of water if the wastewater is not processed well. Therefore, it is important to protect our water resource and seek effective measures and prevention to manage water pollution. There are about 1,970 listed businesses in Pingtung County, including more than 20 industries such as husbandry, food industry, hospital…etc, of which husbandry accounts for 68% as the majority with 1,344 businesses. Environmental Protection Bureau of Pingtung County Government has drafted this project to enhance the examination of unauthorized wastewater discharge and pipelines in Donggang River, while thoroughly inspecting the industries located in the area and testing the water samples collected. With guidance and flagging simultaneously executed, the authority is dedicated to stop the illegal waste discharged by the businesses, scale down the pollution and improve the environment on a larger scale. The project is from 1st January, 2022 to 31st December, but items were required to complete before 30th November, 2022. Below is the summary of the achievement documented till November 30, 2022: I. Inspections on industries in the Donggang River Region and towns nearby a. 988 industry inspections have been completed, of which 745 were on non-herbivorous-animal husbandries, 37 were on herbivorous-animal husbandries, and 206 on the other businesses. 4 major violations (bypass discharge) were found, conducted by 2 non-herbivorous-animal (pig) husbandries, 1 herbivorous-animal (cow) husbandry, and 1 incinerator or waste disposal area. b. The inspection results present that there are 630 husbandries in Donggang River region, of which the anaerobic tanks in 249 wastewater treatment facilities use stainless steel as lid, cement tanks, or gas storage tanks. The installation of anaerobic tank has increased from 23.5% in 2021 to 39.5% in 2022. From 2020 to 2022, there were 72 husbandries installing anaerobic tanks to let waterpower stay longer. In addition, obvious smell from 48 husbandries was detected during inspection. The project will submit the list to air pollution team of Environmental Protection Bureau for them to guide the husbandries to reduce the smell. II. Examination of the water samples 156 collection and testing on water samples have been completed, of which 71 were from other businesses and 7% of them unqualified, 75 non-herbivorous-animal husbandries and 44% of them unqualified, and 10 herbivorous-animal husbandries 100% unqualified. From the results, we can conclude that wastewater discharged from husbandries is the main source of contamination in Donggang River region. There were also 5 collections of effluent from other businesses inspected but not being able to meet the standard, which included 3 hospitals and 2 slaughterhouses. III. In-depth Examination on the wastewater treatment facility functions 6 in-depth inspections have been completed, which were performed on Wang Ranch, Yong Food Industry Co., Ltd. in Chaozhou, Wang hsiang yuan Co., Ltd. in Pingtung, the second factory of Chiang Food Co., Ltd., affiliated slaughterhouse of Kuan Company, and Min Livestock Farm. According to our committee member’s inspection report, their facilities and pipelines were not marked clearly, process of discharging wastewater was lack of consideration, activated sludge was too much or parameter estimation was wrong, and the amount of sludge was abnormal and does not correspond to the current license. To attain the best efficacy of wastewater treatment, we will continue to trace their progress based on the members’ suggestion. IV. Instant surveillance and investigation on pollution The project found several violations from businesses due to illegal disposal of wastewater, incomplete facility, and keeping their effluent without discharging. With the 24-hour water quality surveillance system, it is more efficient to track down violation and reduce the need for inspectors to ambush for a long period. The results were fruitful, which included 5 disposals of wastewater in non-discharging point, 14 examinations of effluent unqualified, and 1 disposal of wastewater in water pollution control area. V. Establishment of non-listed industrial pollution source database a. In the Donggang River region, there were 622 non-listed husbandries, including 256 duck farms with the highest proportion, 249 duck farms as the second highest, 54 goose farms, 46 sheep farms, 2 deer farms, and 15 food factories. The map and statistic database of these non-listed husbandries have been updated. b. The project has completed 29 examinations of non-listed business, including 25 non-listed husbandries (duck farm) and 4 non-listed business (food factory), and flow meters were installed to monitor their daily amount of wastewater discharged. Also, effluent from non-listed business was collected and analyzed to see their impact and load on the contamination of Donggang River. The test result of duck farms was: SS from 78~4,000 mg/L with the average of 28.4 Kg/d for daily pollution, COD from 349~7,370 mg/L with the average of 35.7 Kg/d for daily pollution, ammonia nitrogen 21.3~29.5 mg/L. As the result shows, there were huge differences between water pollutants’ concentration, and the effluent from duck farms with facilities of wastewater treatment contains lower concentration of pollutants than the ones without. Food factories include dried tofu factory, tofu skin factory, and animal viscera factory. For dried tofu factory, SS is 1,620 mg/L and COD 4,450 mg/L; for tofu skin factory, BOD is 2,060 mg/L and COD 919 mg/L; and animal viscera factory SS 55mg/L and COD 213mg/L. The results show that wastewater from non-listed business contributes to contamination load in Donggang River. VI. Cooperation with Environmental Protection Bureau of Pingtung County Government to implement Nightingale and Early Bird and Scale up the Inspections The project has cooperated with Environmental Protection Bureau and scaled up the inspections. 44 tasks have been completed and 204 husbandries have been inspected, of which 14 were found violating the regulations, 13 were found in violation of the 7th article of Water Pollution Control Act, 1 in violation of the 28th article. The total fine has summed up as 306,672 NTD.
