污泥热值的估算

选择了６０９种包括糖、氨基酸、脂肪酸、肽、有机磷，硫化合物的有机物，其燃烧的平均值分别为２３．０２ＭＪ／ＫＧ（碳水化合物）和２４．３８ＭＪ／ｋｇ（其它含Ｎ，Ｐ和Ｓ的化合物）。根据生物化学原理，计算出污泥中有机物的燃烧热（高位热值）为２３．２２ＭＪ／ｋｇ。对几种高有机物含量的污泥进行了热值测定，结果表明，污泥中的有机物干重燃烧热为２３．８６ＭＪ／ｋｇ，与估算值较接近。

船舶电机软启动器的探讨

中燃天津公司原来船舶供油泵的电机．在使用中经常发生启动电流过大、掉闸、继电器、接触器过热等现象，为此经过多方研究、探讨，采用电机智能节电软启动器。并与生产厂家进行多次现场试验和改进，代替原来的Y一△启动器，取得了启动平稳、安全可靠、节电效果显著等多项成果。在各种异步电动机启动运行中效率最高．同时节电效果也最好，是船舶交流电机启动、运行的主要发展方向。     

Effect of leachate recycling and inoculation on the biochemical characteristics of municipal refuse in landfill bioreactors

Activity development of key groups of enzymes involved in municipal refuse decomposition was measured in laboratory landfill bioreactors with and without leachate recycling and inoculation for about 210 days.The results showed that the enzymes(amylase,protease,cellulase,lipase and pectinase)were present in fresh refuse but at low values and positively affected by leachate recycling and refuse inoculation.The total average of cellulase activity in digesters D3 operated with leachate recycling but no inoculation,D4 and D5 operated with leachate recyling and inoculation was much higher than that in digesters D1 and D2 without leachate recycling and inoculation by 88%-127%,117%-162%and 64%-98%.The total average of protease activity was higher in digester D4 than that in digesters D1,D2,D3and D5 by 63%,39%,24%and 24%,respectively,and the positive effect of leachate recycling and inoculation on protease activity of landfilled refuse mainly was at the first two months.The total average of amylase activity was higher in digesters D3,D4 and D5 than that in digesters D1 and D2 by 83%-132%,96%-148%and 81%-129%.During the early phase of incubation,the stimulatory effect of inoculation on lipase activity was measured,but refuse moisture was the main factor affecting lipase activity of landfilled refuse.The inoculation,initial and continuous inoculation of microorganisms existing in leachate,was the mainly stimulatory factor affecting pectinase activity of landfilled refuse.
