摘　　要：文章针对木材蒸煮废水有机物浓度高这一特点,探索性地利用沼气化处理模式对木材蒸煮废水进行处理研究。结果表明,该废水可生化性较差。但是从COD降解效果来看,降解率能达到70%;从产气潜力分析,1 kgCOD大约能产0.316 m3的沼气,且沼气中甲烷含量为58.18%左右;可见,木材加工废水的沼气化处理方法是行之有效的。In view of the wood machining wastewater containing high concentrations of organic matter,anaerobic treatment feasibility of wood machining wastewater was studied in this paper. The results showed that biodegradability was very poor for wood machining wastewater,yet the COD degradation rate could reach 70%,and 0. 316 m3 biogas could be produced per kilogram of COD. The results also showed that CH4 content was about 58. 18%. So the anaerobic treatment for wood machining wastewater producing biogas was feasible.
