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.

武汉城市湖泊环境地球化学研究--以东湖为例

选择武汉市具有代表性的城市湖泊——东湖，进行湖泊底积物及湖水的环境地球化学研究，主要研究了湖水电导率(Ec)的变化趋势和湖泊底积物中重金属Cu、Pb、Zn、Cd、Hg等元素含量的变化规律，最后得出：武汉东湖已经开始受到重金属污染，重金属污染是人类活动直接影响的后果。     

新装修住宅甲醛苯系物污染的探讨

甲醛、苯系物在室内装修的各种人造板材、油漆涂料中大量普遍存在 ,使得室内空气发生甲醛、苯系物污染。通过长时间监测新装修住宅内甲醛、苯系物的浓度变化 ,研究了装璜污染水平与季节、通风状况和装修材料的相关关系 ,得到结论 :甲醛在 1 0 0d之后对人体还有一定危害 ,而苯系物在 1 5～ 60d可挥发完全。并提出新装修住宅装璜污染防治措施     

重庆城区大气颗粒物的元素、离子及物相组成研究

采用X－射线能谱（EDX），傅立叶红外光谱（FT－IR），X－射线衍射（XRI）对重庆市区大气颗粒污染物的元素组成，离子，物相组成进行顾研究，EDX检出了S，Cl,K,Ca,Ti,Cr,Mn,Fe,Cu,Se,Sr,Zr,Rb,Ga,Hg,Zn,Ni元素，FT－IR光谱发现主要存在SO4^2-,NH4^ 和NO3^-,XRD结果表明存在CaSO4.2H2O,α-SiO2,(NH4)2Ca(SO4)2.2H2O,(NH4)2SO4等4个主要物相以及Fe3O4,CaCO3等物相，初步讨论了重庆大气颗粒物的污染来源及其时间，空间分布。
