摘要
采用单相和两相厌氧方法,对含有硫酸盐和难生物降解物质的干法腈纶废水的处理进行了试验研究,结果表明,两相厌氧不仅比单相厌氧CODCr去除率高,运行稳定,硫酸根干扰小,在提高废水的可生化性上也显示出明显的优势。试验中还发现,在pH=7.9～8.2下,硫酸盐还原成为底物降解的主要代谢途径,而在中性pH=6.8～7.1时,甲烷菌的竞争占优势。
Single and two phase anaerobic methods were tested to research their performances in treating dry acrylon wastewater containing sulfate and hard biodegradable substances. The results show that two phase anaerobic process is of higher COD Cr removal efficiency, more stable operation condition, lower sulfate radical disturbance and easier biodegradability compared with single phase one. At pH value between 7.9 and 8.2, sulfate reduction becomes the main metabolic pathway of the substrate degradation. At pH value between 6.8 and 7.1, methanobacteria predominate.
