| 化工废水处理主要特征分析 Analysis of the main characteristics of chemical wastewater treatment 1、化工废水成分复杂，反应原料常为溶剂类物质或环状结构的化合物，增加了废水的处理难度; 1. Chemical wastewater is complex in composition, and the raw materials are usually solvents or cyclic compounds, which increase the difficulty of wastewater treatment. 2、该废水中含有大量污染物物质，主要是由于原料反应不完全和原料或生产中使用大量溶剂造成的。 2. The wastewater contains a large number of pollutants, mainly due to incomplete reactions of raw materials and the use of large quantities of solvents in the production. 3、有毒有害物质多，精细化工废水中有许多有机污染物对微生物是有毒有害的，如卤素化合物、硝基化合物、具有杀菌作用的分散剂或表面活性剂等; 3. There are many toxic and harmful substances. There are many organic pollutants in the fine chemical wastewater, which are toxic and harmful to microbes, such as halogen compounds, nitro compounds, dispersants with bactericidal action or surface active agents. 4、生物难降解物质多，BOD/COD低，可生化性差; 4. There are many biorefractory substances, low BOD/COD and poor biodegradability. |
