【摘要】 化工废水中含有机物、烃类、石油类、重金属等有毒有害物质,成分复杂,难于生物降解,并且对微生物代谢产生抑制和毒害作用。文章通过研究石化废水二级生化处理后回用的工艺技术,提出以絮凝、氧化、膜分离等组合工艺为主体的石化废水深度处理流程,并对设计参数、工艺调试进行优化分析,为石化废水处理回用开辟途径。更多还原

【Abstract】 Petrochemical waste water contains toxic and harmful substances such as organic substances、hydrocarbon、petrole- um category and Heavy metals.The constituents of these substances are so complex that they can’t occur biodegradability easliy, and restrain or poison the microbial enhancement.Through the research on recovery technology of two grades biochemistry treat- ment to petrochemical waste water,the paper express deep treatment processes of petrochemical waste water,whose majorities are combination technology such as flocculation、oxidization and membrane separation,carry out optimization analysis to parameters of design and debug of technology,and set up gateway for treatment and recovery of petrochemical waste water.更多还原
