Laboratory-scale study of the suppression of PCDD/F emission during coal and MSW co-incineration

The experimental test of co-incinerating Chinese raw municipal solid waste （MSW） and coal in a laboratory-scale tubular reactor was first reported in present study, and the emission of normal gas components and the effects of the S/Cl molar ratio or coal mixing percentages on polychlorinated dibenzo-p-dioxins and dibenzofurans （PCDDs/Fs） emission were investigated and discussed. The results indicated that OCDD was the only PCDD homologues since others like TCDD-HpCDD was hardly detected, while as the categories of PCDF homologues were comparatively much more general. The amount of PCDD was much larger than that of PCDF in all operating conditions. Since ZPCDF/∑PCDD〈〈1, the dominant role of the precursor formation was proven in our experimental conductions. With increasing the coal addition to MSW （from 0 to 16%）, PCDD and PCDF were reduced considerably. Coal and MSW may suppress the PCDD/F emissions efficiently （over 95%） during the MSW incineration process. The PCDD/F suppression results of the present study could be helpful guidance to the industrial application of Chinese MSW and auxiliary coal co-incineration processes. The PCDD/F stack emission data of two industrial incinerators using co-incineration technology in China seem to have a great positive reduction of PCDDs/Fs.     

基于地聚合反应的生活垃圾焚烧飞灰资源化利用实验研究

为了实现对城市生活垃圾焚烧飞灰的资源化利用,本实验以城市生活垃圾焚烧飞灰为原材料,通过碱激发法制备出力学性能优异的地聚合物固化体.当碱激发剂的模数为1.0,垃圾焚烧飞灰含量为60％,碱激发剂和固体质量比为1:1.2时垃圾焚烧飞灰基地聚合物的抗压强度最佳.XRD分析结果表明所制备的地聚合物中存在少量碳酸钙和沸石结晶相,S...     

青海省危险废物利用处置能力分析

欧盟废旧纺织品回收再利用相关法规及现状分析

2008年欧盟新修订的《废弃物框架指令(EU)2018/851》增加了建立废旧纺织品分类回收体系、再使用和再利用率目标.2020年欧盟出台的《生活垃圾单独(分类)回收指南》对废旧纺织品单独(分类)回收范围界定,并规定回收后的废旧纺织品,应先分拣出再使用和再利用,之后方可作为垃圾处理.未来欧盟将加大本土废旧纺织品分拣、再...     

冷凝热交换器在危险废物焚烧尾气潜热回收中的应用

由于危险废物焚烧中酸性腐蚀气体的存在，目前从危险废物焚烧尾气中回收热量大多数仅局限于某一温度以上显热的回用，一部分显热和全部的潜热都浪费了。一种用聚四氟乙烯作为管涂层的冷凝热交换器，可使热量回收率大大提高。     

建平县农村废弃物排放和综合利用

随着农村联产承包责任制的实行，农户在生活、生产过程中不断地产生废弃物。如何正确的利用这些废物，降低生产成本，减少对农村环境的污染，具有重要的意义。通过对建平县万寿乡平安地村废弃物利用的现状调查，指出对废弃物的利用途径。     

垃圾焚烧装置连续排放监测

TA Luft 1986,即1986年空气污染控制技术指南,描述了德国排放监测的基本要求。本文讨论了主要污染物的排放测定设备和手工基准方法的技术现状。具有特殊意义的是用计算机获得每天监测记录的自动数据评价。
