摘要
以萍乡钢铁有限责任公司焦化厂焦化废水处理站改造为例,比较了在焦化废水生物脱氮中应用最广泛的A/O工艺和A/A/O工艺,介绍了应用A/A/O工艺对对焦化厂焦化废水处理站进行生物脱氮改造的方案及其主要特点。投产后的进出水水质分析结果表明应用A/A/O工艺处理后的焦化废水能达到排放标准。
A/O technique and A/A/O technique,two of the most widely used techniques of biological denitrification,was compared.The comparison was examplified by the reconstruction of coking wastewater processing station of Ping Xiang Iron Steel Co.,Ltd.The reconstruction plan using A/A/O technique was presented,together with the main features of the reconstruction.The analysis of the quality of the water output from and input to the station showed that the discharged coking wastewater processed adopting the A/A/O technique can meet the required standard.
