摘要
为研究生化污泥的协同处置对炼焦煤性质及焦炭性能的影响,在配合煤(BC)中掺入焦化厂蒸氨废水生化处理污泥(JS)与化工厂煤气制乙二醇生产废水生化处理污泥(HS),进行600 g坩埚焦实验。初步研究表明,JS和HS的官能团组成与BC相近,JS含氰基,污泥的掺入对煤官能团组成与含量影响较小;污泥以较低比例(2%以内)掺入,炼焦煤粘结指数G值变化幅度小于1.2%,焦炭的灰分、挥发分、硫分均满足二级冶金焦标准,机械强度变化幅度小于1%,热态性能变化幅度小于1.4%。JS与HS的低比例掺入对焦炭定向程度与石墨化度的影响较小。
In order to study the effect of collaborative disposal of biochemical sludge on the properties of coking coal and coke,the blended coal(BC)is mixed with the sludge(JS)from biochemical treatment of ammonia steaming wastewater in coking plant and the sludge(HS)from biochemical treatment of ethylene glycol production wastewater in chemical plant,and then conducted for 600 grams’crucible coke experiment.Preliminary research shows that the functional groups composition of both JS and HS is similar to that of BC.JS contains cyano.The addition of sludge JS or HS has little impact on the composition and content of functional groups of coal.When the sludge is mixed at a lower proportion(within 2%),the change range of G value of coking coal is less than 1.2%,the ash,volatile and sulfur contents in coke meet the standard of secondary metallurgical coke,the change range of its mechanical strength is less than 1%,and the change range of its thermal performance is less than 1.4%.The low proportion of JS and HS has little effect on the orientation degree and graphitization degree of coke.
