摘要

工业废水由于其高浓度的有机物和有限的生物可降解性而成为日益严峻的环境挑战。然而，到目前为止，还没有出版的作品讨论工业废水的表征，这是本研究的重点。此外，还研究了水热处理对化学需氧量(COD)去除和可溶性化学需氧量(SCOD)释放的影响。从不同的工业场所收集了废水样品，并对其进行了表征，以确定其初始性质。综上所述，EC估算的废水盐度较低，pH值在可接受范围内。另一方面，所有样品经水热处理后均获得较高的钠吸收比(SAR)。尽管如此，我们的研究结果显示，水热处理后的SCOD释放量较高，表明该处理技术可以获得更好的COD去除效率。

The effect of hydrothermal treatment on industrial wastewater: Hungary as a case study

Industrial wastewater is a growing environmental challenge due to its high concentrations of organics and its limited biological degradability. Up to date, however, no published work discussed industrial wastewater characterization, which is the focus of this study. Moreover, the effect of hydrothermal treatment on the chemical oxygen demand (COD) removal and the soluble chemical oxygen demand (SCOD) release was investigated in this work. Wastewater samples were collected from different industrial sites and characterized in order to determine their initial properties. It was summarized that the salinity of wastewater estimated by EC was relatively low, and its pH values were in the acceptable range. On the other hand, however, high values of sodium absorption ratio (SAR) were obtained in all samples post to hydrothermal treatment. Nonetheless, our results revealed higher SCOD release post to hydrothermal treatment suggesting better efficiency of COD removal obtained by this treatment technique.
