溶胞预处理技术

Preconditioning Techniques of Cell Lysis

城市污水厂采用厌氧消化工艺,减少污、废水处理中剩余污泥的产生量,同时,实现对生物污泥的资源化利用。为了提高厌氧消化过程的效率,各种溶胞技术被用于厌氧消化的预处理。介绍了当前研究和应用较多的各种化学、物理、生物溶胞技术,分析了污泥溶胞预处理的原理、特点和处理效果。

Currently, municipal wastewater treatment plans begin to adopt anaerobic digestion processes to reduce the sludge production in wastewater treatment, and to achieve resource utilization of biological sludge. In order to enhance process efficiency, serials of cell lysis techniques are employed in the precedence treatment of anaerobic digestion. In this article, different cell lysis processes studied or applied, including chemical techniques, physical techniques and biological techniques are reviewed. The mechanisms, characteristics and treatment efficiencies are analyzed.
