Oily sludge is a kind of mixture that is extremely harmful to the environment. Anaerobic digestion (AD) is a commonly used method for biodegrading oily sludge. However, the AD treatment cycle is usually long and inefficient. Here, we developed an approach to improve the degradation rate of oily sludge by integrating subcritical hydrothermal pretreatment (SHP) and AD.

亚临界水热预处理提高含油污泥的厌氧降解

油性污泥是一种对环境极为有害的混合物。厌氧消化（AD）是生物降解油性污泥的常用方法。但是，AD治疗周期通常较长且效率低下。在这里，我们开发了一种通过整合亚临界水热预处理（SHP）和AD来提高油性污泥降解率的方法。
