摘要
在废水生物处理过程中,存在对微生物具有抑制的毒性物质,影响废水的生物处理。不同控制条件下,有毒物质毒性阀值有很大差异。文中就pH、水温、溶解氧、处理工艺、水力停留时间、生物体浓度、驯化等因素对有毒物质毒性阀值的影响进行了较系统的分析,在此基础上提出研究废水生物处理中毒性阀值需要解决的问题。
The existence of toxic substances in wastewater can inhibit the Microbial activity and influence the effect of biological wastewater treatment. Toxic substances have very different toxicity threshold in different control conditions. In this paper, the influencing factors of toxic substances＇toxicity threshold, such as pH, water temperature, dissolved oxygen, treatment technology, hydraulic retention time, the concentration of organisms, domesticated, is analysised systematicly. On this basis, some questions about researching toxic substances＇toxicity threshold is need to be addressed on biological wastewater treatment.
