摘要：

中试试验表明,臭氧生物炭工艺经改造后可成功应用于炼化废水深度处理回用流程中。当废水中臭氧质量浓度为18.12g/m^{3<\sup>时,石油类、COD、细菌的去除率分别达到79%,28%,100%,BOD/COD值提高至0.237;生物炭工艺经曝气、加碱工艺改造后对石油类、COD、氨氮的去除率达到100%,39.7%,87.1%,出水符合循环水补充水水质要求。}

Abstract:

The problems existing in the determination of heterotroph in industrial circulating water system in China is analyzed.A kind of rapid determination of heterotroph in industrial circulating water has been studied.This method can beoperated simply(The amount of work is only one fifth of the original amount).The result is accurate and reliable.It issuitable for determinations of water quality and evaluations of biocide,and is worth popularizing.

Key words: wastewater reuse, ozone, biological activated carbon, oil refining wastewater
