摘要
我国市政污泥产量巨大,其处理处置与资源化关系着我国环境卫生的健康发展。市政污泥热解技术可以使污泥热解产物再利用从而实现资源化,已成为市政污泥处置的研究热点之一。本文主要介绍了微波热解、高温热解、低温热解等三种主要市政污泥热解技术,概括了热解温度、升温速率、停留时间、热解压力、催化剂、物料性质等对污泥热解产物特性的影响。对于填埋多年的存余污泥,对其热解规律及资源化可行性进行了分析。最后基于市政污泥热解技术的发展和存在的问题,对将来的研究趋势和方向提出了建议和总结。
China's municipal sludge production is huge,and its disposal and resources are related to the healthy development of environmental sanitation in China.Municipal sludge pyrolysis technology can reuse the pyrolysis products of sludge to realize resources,which has become one of the research hotspots in municipal sludge disposal.This paper mainly introduces three major municipal sludge pyrolysis technologies,including microwave pyrolysis,high temperature pyrolysis,and low temperature pyrolysis.Theinfluence ofseveral influencing factors such as pyrolysis temperature,heating rate,pyrolysis pressure,catalyst onpyrolysis product characteristicsis summarized.The pyrolysis law and resource feasibility of the sludge remaining in landfill for many years are analyzed.Finally,based on the development and existing problems of municipal sludge pyrolysis technology,suggestions and conclusions for future research trends and directions are put forward.
