高浓度染料废水处理工程设计与运行
|
摘要
江苏某化工企业以生产发散性染料为主,生产过程中产生大量的高氨氮、高COD和高色度废水,原废水处理工艺已无法使出水水质达到排放标准。在小试和各车间水质分析的基础上改造原有工艺,采用除氨氮膜设备+Fe-C/Fenton+ABR+UASB+两级生化曝气池工艺处理该厂染料废水。工艺改进后,出水的各项指标符合该化工园区污水处理厂的接管标准。
A large amount of wastewater with high ammonia nitrogen,high COD and high chromaticity was produced by a chemical company engaged in divergent dyes production in Jiangsu. The original wastewater treatment process was unable to meet the discharge standards. On the basis of pilot test and the water quality analysis of each workshop,the original process was reconstructed into the combined process of ammonia-nitrogen membrane equipment/Fe-C Fenton/ABR/UASB/two-stage biochemical aeration tank. After the improvement of the process,the effluent quality could meet the take-over standards of the sewage treatment plant in the chemical park.
