應用廢混凝土處理養豬廢水中難分解之污染物

摘要: 以水泥混凝土廢料,用來處理養豬事業廢水中難以生物分解的污染物.在臺灣,大多僅以固體分離、厭氧處理、耗氧處理三個階段來處理養豬廢水.并且為減少事業用水量,所以再將處理后的廢水用來清洗豬舍.然而,廢水中有些成份及堆積物,是難以被微生物所分解的,所以廢水回收再利用后,水中的化學需氧量將不斷累積.在本研究中使用氣相層析質譜儀(GC/MASS)及紅外線光譜分析儀(FT-IR)對三個不同處理階段中的廢水進行大量的成份分析,分析結果顯示,難以降解的污染物主要是以含苯基的氨基酸為主,并選擇將混凝土廢料置入廢水中來去除這些成份.實驗結果顯示,難以處理的成份可被混凝土廢料有效的去除,亦可將混凝土廢料的pH降低至11以下,并可當土壤改良劑使用. Abstract: In this study swine wastewater was treated with waste concrete to remove the refractory pollutants, which were difficult to be biodegraded. In Taiwan, most of the swine wastewater is treated with a three-stage process. The process includes solid separation, anaerobic reactor and aerobic reactor. Water after the aerobic reactor is partly recycled to wash the pig house for reducing water consumption. However, with the accumulation of some components that are difficult to be biodegraded, the COD of the effluent increased continuously. The refractory components in the effluent of the three-stage process were first identified by GC/MASS and FT-IR analysis. Analysis results showed that the refractory pollutants in the swine wastewater were amino acid with phenyl group. The waste concrete was chosen to remove these components. Experimental results showed that the refractory components could be removed efficiently by waste concrete. The used concrete particles have the pH value lower than 11. They can be used as a soil conditioner 作 者: 周良勛    盧俊谷    CHOU Liang-hsing    LU Chun-ku   作者單位: 周良勛,CHOU Liang-hsing(嘉義大學土木與水資源工程系,臺灣,嘉義,600)
