摘要


本計畫旨在提供養豬農民快速推估排放水水質的方法,以利於隨時監測厭氣處理後及三段式處理後之水質情況。本計畫透過本所及各繁殖場廣泛收集場內、外豬糞尿處理水樣,分析並取得各項資料。總計收集分析1,884件水樣,經細分歸類及篩選可用資料,並建立相關性,其中以豬糞尿水經三段式處理後之排放水,其透視度化學與參數BOD、COD及SS三者間,經乘冪迴歸所得,具有中等程度以上之相關。其透視度(Tr)與BOD、COD及SS之迴歸方程式及R^2分別如下:(1)BOD=651.35(Tr)^(-1.1752),0.72;(2)COD=1772.1(Tr)^(-0.8817),0.76;(3)SS=585.88(Tr)^(-1.2657),0.81。因此,以物理參數透視度來推估養豬場排放水之BOD、COD及SS,具有一定程度之可靠性。

This project was aimed to provide farmers with a rapid method for estimating water quality of anaerobically and three-step treated piggery wastewater. A total of 1,884 samples collected from the Taiwan Livestock Research Institute and its propagation stations was analyzed. From regression analysis, each of the chemical parameters such as BOD, COD and SS of piggery wastewater was highly correlated with its transparency (Tr). The regression equations and R-square of BOD, COD and SS for the three-step treated piggery wastewater were: (1) BOD=651.35 (Tr)^(-1.1752), 0.72; (2) COD=1772.1(Tr)^(-0.8817), 0.76; (3)SS=585.88(Tr)^(-1.2657),0.81; respectively. Accordingly, transparency was a reliable physical parameter for estimating BOD, COD and SS of piggery wastewater.
