石化污水回用于循环冷却水技术的研究

Research on the application of petrochemical wastewater to circulating cooling water technique

通过对石化污水水质特性的研究,阐述了石化污水中的氨氮、硫化物、石油类、微生物、悬浮物、含盐量在不同浓度下对循环水水质处理的影响,提出了石化污水回用水的参考水质标准。并经过工业应用试验验证,指出达到国家一级排放标准的石化污水直接回用于循环冷却水在技术上是可行的。

The characteristics of petrochemical wastewater quality have been studied. The influence of NH3-N,sulfide, petroleum,microorganism, suspended soid and TDS(total dissolved solid)with different concentration in petrochemical wastewter on the water quality treatment of circulating cooling water has been demonstrated. A referential standard of water quality for petrochemical wastewater reuse is presented. Through tests in industrial application, it is pointed out that the direct reuse of petrochemical wastewater, which has come up to the first grade discharge standard, in circulating cooling water technique is feasible.
