| 中文摘要 |
| 以天津某染化厂的酸性橙Ⅱ废水为研究对象，利用Ｎ235-煤油－Ｈ2ＳＯ4－ＮａＯＨ的萃取－反萃取体系，通过静态杯皿实验，确定了萃取－反萃取过程的最佳工艺参数，使萃取效率可达９０％ ，出水ＣＯＤ值可降低到３５０ｍ ｇ／Ｌ；酸性橙Ⅱ废水的有机成分总浓缩倍数达２５～４０倍；废水的萃余液经二次萃取法和混凝沉淀法处理后，出水的ＣＯＤ值＜ ２００ｍ ｇ／Ｌ，色度＜ ８０倍，达到天津市工业废水的排放标准 |
| 英文摘要 |
| The process of resource recovery from the acid orange Ⅱ wastewater discharged by a plant in Tianjin was researched by using the extraction and back-extraction system,which is made up of N235-H2SO4-NaOH According to a series of batch tests,the optimum process parameters were obtained The extraction efficiency is more than 90 percent,and the COD of the effluent is 350mg/L The total valuble organic substances in the acid orange Ⅱ wastewater is concentrated 25～50 times After the secondary extraction process and the coagulation precipitation process,COD in the effluent is less than 200mg/L,and the value of color is less than 80,reaching the Industrial Wastewater Discharge Standards of Tianjin |
