生活垃圾水解液处理研究进展

Research Progress of Domestic Waste Hydrolysate Treatment

亚临界水解燃料化技术是一种新型的生活垃圾处理方式,但其水解后产生的生活垃圾水解液难以处理限制了该技术的推广。介绍了生活垃圾水解液(DWH)的来源及性质,从混凝沉淀法、微电解法、厌氧法和电解法四个方面分析了这些处理技术的原理,综述了其处理不同污水的效果,并结合验证实验进行了评价。证明电解法因为处理时间短、处理效率高的特点更适用于水解液废水的处理,为后续的工程实践提供了指导。

The use of subcritical hydrolysis fuelling technology is a new type of domestic waste treatment,but the difficulty of treating the domestic waste hydrolysate produced after its hydrolysis limits the promotion of this technology.This article describes the sources and characteristics of domestic waste hydrolysate(DWH).The characteristics of these treatments were evaluated from four aspects:coagulation and precipitation,microelectrolysis,anaerobic and electrolysis,their effectiveness in treating different wastewater was reviewed and in conjunction with validation experiments.It is proved that the electrolysis method is more suitable for the treatment of hydrolysate wastewater because of its short treatment time and high treatment efficiency,which provides guidance for the subsequent engineering practice.
