Hydrothermal treatment (HT) is an emerged thermochemical approach for the utilization of biomass. In the last decade, intense research has been conducted on bio-oil and hydrochar, during which extensive amount of hydrothermal treated wastewater (HTWW) is produced, containing large amount of organic compounds along with several toxic chemicals. The composition of HTWW is highly dependent on the process conditions and organic composition of biomass, which determines its further utilization. The current study provides a comprehensive overview of recent advancements in HTWW utilization and its properties which can be changed by varying different parameters like temperature, residence time, solid concentration, mass ratio and catalyst including types of biomasses. HTWW characterization, parameters, reaction mechanism and its application were also summarized. By considering the challenges of HTWW, some suggestions and proposed methodology to overcome the bottleneck are provided.
水热处理 (HT) 是一种新兴的热化学方法，用于利用生物质。在过去的十年中，人们对生物油和水热炭进行了大量的研究，在此过程中产生了大量的水热处理废水 (HTWW)，其中含有大量的有机化合物和几种有毒化学品。HTWW 的组成高度依赖于工艺条件和生物质的有机成分，这决定了其进一步的利用。本研究全面概述了 HTWW 利用及其性质的最新进展，这些性质可以通过改变不同的参数来改变，如温度、停留时间、固体浓度、质量比和催化剂，包括生物质的类型。还总结了 HTWW 的特性、参数、反应机制及其应用。通过考虑 HTWW 的挑战，提供了一些建议和提出的方法来克服瓶颈。
