摘要
针对某市政污水处理厂实际问题，开展了废水COD组分划分和废水生物抑制毒性测试等实验研究，并对废水溶解性有机组分进行了半定量分析。结果显示：该废水含有约40～50mg／L的以半挥发性有机物（SVOC）为主的难生物降解COD组分；含有较高浓度的挥发性有机物（VOC）类物质，导致其表现出明显的生物抑制毒性。
This study was carried out due to the practical problems of a municipal sewage treatment plant.COD fractionation of wastewater, wastewater biological inhibition toxicity testing and semi quantitative analysis of dissolved organic components were conducted. The results showed that the wastewater contained about 40-50 mg/L SVOCs as biodegradation-resistant COD components.The wastewater contained high concentration of VOCs, resulting in obvious biological inhibition toxicity.
