脱盐-A/O组合技术处理高盐度高COD有机废水的研究

许多工业生产过程中会排放高盐度、高COD有机废水,不仅含有大量的悬浮态、胶体态和溶解态的有机物质,还含有高浓度的无机盐类(此类废水污染严重,是属于极难处理的废水)。通过工程实例,文章介绍"脱盐-A/O"组合技术处理这些高盐度、高COD有机废水的效果及主要设计参数。运行结果表明,最终出水水质达到广东省地方标准《水污染物排放限值》(DB44/26-2001)第二时段一级标准。组合技术处理高盐度、高COD有机废水效果好,同时还能产生经济效益。

Research on Desalination-A/O Combination Craft in High Salinity and High COD Organic Wastewater Treatment

Many industrial producing processes discharge high salinity and high COD organic wastewater,it contains not only lots of suspended,colloidal and soluble organic substance,but also high concentration inorganic salts.The water pollution is very serious and hard to treat.Through the project example,the paper introduced the effect and the main design variable using "Desalination-A/O" combination craft in high salinity and high COD organic wastewater treatment.The movement results indicated that the final leakage water quality achieved the Guangdong Province local standard "Discharge limits of water pollutants"(DB44/26-2001) second time interval level standard.The combination craft had a good effect in high salinity and high COD organic wastewater treatment,it also brought economy benefit.
