【摘要】 本文针对城市生活垃圾组成成分的特征,提出将城市生活垃圾中可以厌氧分解的生物质部分进行分类收集,采用厌氧发酵技术进行处理,将其各种产物分别收集,进行资源化利用。通过实验,探索生物质垃圾厌氧分解特性、产出液性质以及资源化利用途径。（1）为分析生物质垃圾厌氧过程中脱液特性,设置在中温（38℃）、高温（45℃）和超高温（70℃）3个恒温阶段下实现生物质垃圾厌氧反应过程,实验发现生物质垃圾厌氧反应效率随温度升高而增加,厌氧反应达到稳定的时间随温度升高而逐渐减少,其产出液中的可溶性有机物浓度随温度升高也呈快速增加趋势。（2）采用磷酸铵镁（MAP）沉淀法探讨对产出液氨氮的去除,经过实验发现,当pH值=9.5,N∶Mg=1.3,N∶P=1.2时处理效果最好,去除率可达到70%。（3）以产出液为添加水,以精煤为原料配制垃圾液煤浆。实验发现,单峰最佳粒度级配D_100-200目∶D_200目以下为3∶7,最佳煤液比为1.7∶1,此时液煤浆浓度值为65.3%,粘度值为915.6mPa·s,稳定性为一级,热值为32124.14kJ/kg,灰分为10.20%。双峰最佳粒度级配:D_100-200目∶D_200目以下为3∶7,D_200-250目∶D_250目以下为5∶5,煤液比为1.7∶1,此时液煤浆浓度值为66.74%,粘度值为1087.4mPa·s,稳定性为一级,热值为34747.34kJ/kg,灰分为10.36%。更多还原

【Abstract】 In this article,contraposing the componential characters of city solid waste,the view that collecting solely the biology waste which can be decomposed by anaerobe was put forward.And the biology waste was disposed by the technique of anaerobic zymosis.Then the every production was collected lonely to utilize as resource.Through the experiment, the anaerobic zymosis character of the biology waste,the property and the approach of utilizing as resource for the leachate.（1）For analyzing the anaerobic zymosis character of the biology waste,the anaerobic reaction would be carried through in three constant temperature phases—medial temperature（38℃）,high temperature（45℃）and super high temperature.Then in the disparate temperature,the law would be found between the quantity of leachate,CODCr and NH3-N of leachate and reaction times in anaerobic zymosis of biology waste.（2）Use of magnesium ammonium phosphate（MAP）for removing ammonia in the output liquid,the experiment found that when the pH value=9.5,N:Mg=1.3,N:P=1.2, the treatment effect is the best,removal rate can reach 70%.（3）Author regard the output liquid as adding water,coal as raw material to confect waste coal slurry.It was found that the best single-size class with D_100-200:D₂₀₀=3:7,the best coal and water ratio=1.7:1,at this time coal slurry of the concentration value will reach 65.3%,viscosity value reach 915.6 mPa·s,the stability reach the first class,thermal value reach 32124.14kJ/kg,ash reach10.20%.And the best bimodal size class with:D_100-200: D₂₀₀= 3:7,D_200-250:D₂₅₀=5:5,the coal and water ratio=1.7:1,at this time coal slurry of concentration reach 66.74%,the viscosity value reach 1087.4mPa·s,the stability reach the first class,thermal value reach 34747.34 kJ/kg,ash reach 10.36%.更多还原
