Abstract

本发明公开了一种利用太阳能热解碳化技术处理污泥的方法,含以下步骤:取城市污水处理产生的污泥,置于热解碳化炉中,在密封、无氧、非燃烧状态下进行包括汽化、热解、脱氢、热缩化和碳化的一系列反应,生成尾气、生物炭和焦油,其中热解碳化炉由太阳能供热系统提供热源,反应条件为高温常压或高温高压或中高温高压,所述的高温为500~800℃,所述的中高温为200~400℃,所述的高压为1~16MPa。本发明方法能实现污泥在污水厂内彻底处理处置,无二次污染,能量利用率高,运行费用极低,回收可再生资源,真正彻底实现污泥处理处置的减量化、稳定化、无害化及资源利用化。
The invention discloses a sludge treatment method using a solar pyrolysis carbonization technology. The method comprises the following steps: adding the sludge produced by municipal sewage treatment into a pyrolysis carbonization furnace, carrying out a series of reactions, including vaporization, pyrolysis, dehydrogenation, pyrocondensation and carbonation, in a sealed, oxygen-free and non-burning state, wherein a heat source of the pyrolysis carbonization furnace is provided by a solar heat supply system, the reaction condition is high temperature and normal pressure, or high temperature and high pressure, or moderate-high temperature and high pressure, the high temperature is 500-800 DEG C, the moderate-high temperature is 200-400 DEG C and the high pressure is 1-16MPa. With the method provided by the invention, thorough treatment disposal of the sludge in a sewage plant is realized, secondary pollution is avoided, energy utilization rate is high, operation cost is very low, renewable resources is recycled, and reduction, stabilization, reutilization and resource utilization of sludge treatment disposal are really implemented completely.
