農民使用過的農藥塑膠空瓶，常有因為回收去化管道受阻造成農藥空瓶罐遭任意棄置，危害環境。保境公司為解決農藥廢容器去化問題，積極接受環保署輔導進行農藥廢容器回收處理廠設置，並與財團法人台灣產業服務基金會共同合作，透過實場試驗針對異味/VOCs進行檢測，並建立適當的污染防制處理方式。 本計畫試驗各防制處理流程之成效，由(1)廢氣水洗後導入活性碳，THC入口為74ppm，出口為38ppm，處理成效約50%。(2)廢氣導入水洗設備，因檢測當日儀器突發失常，故由下午測值推估廢氣THC入口約>500ppm，出口測值為519ppm，水洗設備處理前後THC值接近。(3)廢氣直接導入活性碳，THC去除率約65.2~73.7％，排放管道之異味介於55~412，遠低於法規標準1,000。 針對廢氣導入活性碳設備，本計畫建議活性碳之更換頻率，應於穩定操作與處理濃度變化小的原則下，輔以安全係數1.5，推估50公斤活性碳約可處理40公噸廢農藥容器產生的空氣污染物。在環保法規符合度方面，該廠已具水污染防制措施許可，產生之廢水排入芳苑工業區污水廠並符合納管標準。另檢測該廠排放管道之21種VOCs，測值均為ND；周界異味於廠區內上風處為16、下風處分別為16與21，遠低於法規標準50；檢測周界60種VOCs有18種物質被檢出，測值介於0.0007~0.059mg/m3之間，遠低於法規標準0.0046~99 mg/m3。

The empty plastic pesticide bottles used by farmers have no where to go now, which may result in environmental hazards due to abandonment of empty bottles at will. To solve the problems of disposing waste pesticide containers, Bo Jing Co. actively establish the waste pesticide container recycling field with counseling of Environmental Protection Administration as well as cooperate with Foundation of Taiwan Industry Service to conduct on field tests aiming at odor/VOCs to the expectation of establishing pollution prevention treatment methods as appropriate. The effects of different prevention treatment processes under this projects: (1) Waste gas through into water wash and activated carbon absorption, the input of THC is 774ppm while the output is 38ppm, with processing effect around 50%; (2) Waste gas through into the washing equipment, the estimate of waste gas THC at inlet >500ppm based on the value tested in afternoon since the instrument was malfunctioned in morning and 519ppm at outlet. The THC value is similar before and after washing process; (3) Waste gas through into activated carbon absorption, the THC elimination rate is around 65.2~73.7% while the odor discharged in the pipe is between 55~412, which is far below the statutory standard 1,000. Aiming at the introduction of activated carbon equipment, this project suggests that the replacement frequency of activated carbon should follow the principle of stable operation and small variation on processed concentration. And the operation of replacement frequency considers by the safety coefficient 1.5. It is estimated that 50kg activated carbon may process 40 tons of air pollutant generated from waste pesticide container. In term of environmental regulations compliance, the water pollution prevention procedures of said plant have been approved and the waste water discharged to Fangyuan Industrial Park is satisfactory to the control standards. In addition, the test values of 21VOCs in drainage channel are all ND. The perimeter odor at the windward position of plant is 16 while 16 and 21 at the downwind position, which are far below the statutory standard 50. There are 18 materials detected as testing the perimeter 60VOCs with test value between 0.0007~0.059 mg/m3 and far below the statutory standard 0.0046~99 mg/m3.
