Abstract
台灣地區之豬糞尿廢水經三段式處理法後排放，此排放水富含植物所需之無機物質，如能將此水以「土壤處理」作為供應植物生長之養分、不直接進入水體，將可有效地利用排放水且大大地降低對周圍環境之污染。本研究目的為將豬糞尿廢水經過三段式處理之排放水，在台灣地區灌溉至蔗田及牧草地，處理區之施灌量相當於100 mm水深，對照區則施用化學肥料，探討此施灌量對土壤品質及甘蔗與盤固草生長及品質之影響，尤其是銅、鋅含量累積之影響。試驗地分別為臺南試區與嘉義試區，經過兩年（2001－2002）進行監測與研究，建立完整之監測資料庫。研究結果顯示兩試區於施灌豬糞尿二級處理排放水後的兩年內，對兩試驗區土壤之酸鹼度、導電度、可交換性鈣、鎂、鉀、納、有機碳、有效磷含量、有效銅鋅含量、或甘蔗與盤固草之主要元素（氮、磷、鉀、鈣、鎂）及微量元素（鐵、錳、銅、鋅）含量等，尤其兩年兩次施灌對土壤之銅鋅濃度及甘蔗與盤固草植體中之銅鋅濃度並無明顯增加。兩年監測與研究結果可提供台灣地區畜產處理廢水一個安全、無污染再回收利用及管理之制度，以達到水資源與養份資源再利用之目標，並作為評估目前三段式豬糞尿廢水處理之排放水以「土壤處理標準」相關規定檢討之依據。
To reduce the environmental pollution, wastewater can be recycled and reused on rural agricultural soils. Treated swine wastewater (TSW) land applications contain abundant amounts of nutrients and water for crop uptake. The objectives of this study are to monitor the effects of TSW land application on the soil quality, crop quality and productivity of sugarcane and pangolagrass pastures. The accumulation of copper and zinc in the soil and crop will be monitored. Tainan and Chiai experimental sites were selected for monitoring from 2001 to 2002. The TSW land application rate in the rural soil and pasture sites was 100 mm TSW depth per year in the treated plots. We applied chemical fertilizers based on the fertilization recommendation for sugarcane and pangolagrass pastures. The results from the monitoring system, indicated that the soil pH, electrical conductivity (EC), exchangeable Ca, Mg, K, and Na, organic C, available P, Cu, and Zn in rural soil treated plots showed no significant difference from the control plot without TSW application at two experimental sites (P ＞ 0.05). The results also indicated that there was no significant difference between the macro elements (N, P, K, Ca and Mg) and microelements (Fe, Mn, Cu and Zn) on leaf quality and productivity in sugarcane and pangolagrass pastures (P ＞ 0.05). There was no significant effect on the accumulation of Cu and Zn in the soils in sugarcane or pangolagrass pastures after two TSW applications at the two sites. The results from this two year monitoring system in field sites can provide a safe, recycling and management system for recycling. The TSW land application regulations announced by the Taiwan EPA in 1999 can be evaluated and revised accordingly.
