Abstract:This paper analyzes the procreant gases through the intermittent anaerobic digestion experiences of MSW.The experimental consequences illustrates:(1)the procreant gases of this process are produced by these microbi— al interactions in the system,and the rate of procreant gases and the variation of methane content nearly include the stage of methane-producing,the exponential growth of methane content,the steady growth of methane content and the degres— sive growth of methane content,which are in corresponding to the slow、exponential、steady and decadent growth stages of methanogens accordingly.(2)the ratio relation between the CH4 content dnd methanogens content in these methane is: 一愚 ,the c。efficient愚stands f0r the t。ken。f the actiVity。f methan。gens.At the same time,it educes that the coefficient肚 is 0.142 d_。and Kd is 0.0612 d_。and k(mL/gVSS)is 0.041,0.041,0.000,一0.0968 relatived to the four phases through the experiment simulation.Morever,it can judge the different stages of methanogens and prepon— derant bacterium in the system in terms of—d Y. fit Keywords:municipal solid waste(MSW);anaerobic digestion(AD);methane output;microorganism;metha— nogens;methane content ’ 2一羟乙基吡啶生产工艺开发成功 淄博张店东方化学股份有限公司近日成功开发2一羟乙基吡啶生产工艺,并获得国家发明专利,填补了该技术的国内空白。 2一羟乙基吡啶是一种高技术含量、高附加值的精细化工产品,在高分子材料、表面活性剂、医药等方面有着广泛的应用。2004 年前,我国该产品全部依赖进口,每年的进口量约2500 t。淄博张店东方化学股份有限公司以2一甲基吡啶与甲醛为原料,采用低 温、低压间断式缩合反应新工艺,在8O t・a 中试装置的基础上建成年产500 t 2-羟乙基吡啶装置。新工艺具有操作便利、反应在 低温低压环境下进行、安全性高等特点,同时原料消耗低、副产物少、后处理相对简单,既降低了生产成本、减少了污染,又可将产品 纯度提高到98 以上。 【捅编J
