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睛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。

Research on the Dry Acrylon Wastewater Treatment by Single and Two Phase Anaerobic Methods
tract:Single and two phase anaerobic methods were tested to research their performances in treating dryacrylon wastewater containing sulfate and hard biodegradable substances. The results show that two phase anaerobic process is of higher CODcr 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.
Keywords: acrylon wastewater; wastewater treatment; anaerobic
全国5套同类型干法臆纶生产装置均采用-好氧-生物活性炭处理工艺，由于干法腈纶废水中含有一定浓度的硫酸盐和难生物降解物质，影响了系统对CODcr的去除率和运行稳定性，目前该工艺不能使出水达到国家排放要求。
1.1.1试验水样
干法腈纶工艺废水中含有油剂、丙腈磺酸钠、聚丙烯腈等有机物，它们以胶体或悬浮物形式存在于水中，经混凝沉淀后，其水质情况见表1。
