为探讨固定化菌株DF51对苯酚污染土壤中小麦幼苗生长的影响,采用随机区组试验设计,在大田条件下研究施用不同质量浓度的苯酚(0、50、100、150、200μg/g)和固定化菌株DF51(0、10、20、30、40 kg a.i./hm2)对小麦的影响.结果表明:苯酚显...为探讨固定化菌株DF51对苯酚污染土壤中小麦幼苗生长的影响,采用随机区组试验设计,在大田条件下研究施用不同质量浓度的苯酚(0、50、100、150、200μg/g)和固定化菌株DF51(0、10、20、30、40 kg a.i./hm2)对小麦的影响.结果表明:苯酚显著降低小麦的光合特性和抗逆性;固定化菌株DF51对苯酚土壤污染具有修复性能,且能提高苯酚胁迫下小麦的光合特性和抗逆性;P1D1和P2D2处理可恢复苯酚胁迫下小麦的生理特性.可见,固定化菌株DF51能显著提高小麦在苯酚胁迫下的耐性,这与其提高抗氧化酶活性有关.展开更多

Chuzhou City, situated between Yangtze River and Huai River, is a window city in the east of Anhui Province. A landfill site with a capacity of 400 ton per day is to be constructed according to the city development plan and the garbage amount, This paper summarizes the landfill location, landform, groundwater, surface water, landfill stratal configuration, dominant wind, and the major machinery equipment. The projects of anti-percolation, seepage collection, seepage disposal, rainwater discharge, biogas diversion are deeply studied. The advanced design principle of the landfills is summarized, which is environment-friendly, science-oriented and economy-based. Environment-friendly principle is implemented in the selection of landfill location, construction of all projects, sealing up project and perfecting environment monitoring system; science-oriented principle prescribes that the design, construction, and management should be science-oriented; the selection of landfill location, design, plan optimization, resource-saving measures and comprehensive utilization should be economy-based Chuzhou domestic waste landfill site is qualified as a goiden model in this paper.展开更多
