通过在青岛湖岛垃圾场的现场试验,研究了城市垃圾填埋场上植树造林的方法、适宜树种的筛选以及影响树木成活和生长发育的主要因素。结果指出,垃圾中有机质发酵所产生的甲烷气体是抑制树木成活和生长的关键因素。覆土层除为树木提供支持和生存环境外,还能阻挡甲烷气体的逸出,因此,土层越厚,越有利于树木成活和生长。还对18种木本植物对甲烷气体的耐性进行了筛选。

Sanitory landfill is the main measure for treating municipal solid waste in the cities of China today. Municipal solid waste is the major component of landfill, which has wide rubbish sources, complex ingredients, containing great amount of corrosive materials and pathogenic organisms, so the surroundings of the landfill site are unavoidable to bring about harmful effect.

Sanitory landfill is the main measure for treating municipal solid waste in the cities of China today. Municipal solid waste is the major component of landfill, which has wide rubbish sources, complex ingredients, containing great amount of corrosive materials and pathogenic organisms, so the surroundings of the landfill site are unavoidable to bring about harmful effect. Taking Laogan landfill as example, which has been established as a vegetative ecosystem, to investigate the effect of plants on recovering the environment. Through comparison, in fact, it showed that the plants could absorb great amount of hazardous elements from soil, and degrade or eleminate certain pollutants, improving air pollution and ameliorating the surroundings.

卫生填埋是目前我国城市生活垃圾处置的主要手段。以城市生活垃圾为主要成份的卫生填埋场,由于来源广、成份复杂、含有大量的易腐有机物和带病原菌的污染物,不可避免地给填埋场周边环境带来一定影响,有些甚至是较严重的影响。该文以上海老港垃圾堆场建立的植被生态系统为例展开调研,以众多翔实的数据说明了植被在垃圾填埋场环境恢复中的作用。通过比较证明,植被改善了土壤生态环境;植物能吸收垃圾中大量的有害元素,对污染物起到降解和消减作用;并能减轻周边地区的大气污染程度,使填埋场的环境质量及其景观均有所改善。

The pollution caused from life garbage and leachate on environment and creatures is becoming an increasingly prominent problem in the process of development of Guangzhou City. Wastewater leached from Likeg Life Garbage Landfill of Guangzhou contained high concentrations of pollutants,and did not reach the effluent standard,which could be harmful to plants and surroundings. Of four plant species investigated in this study, Eichhornia crassipes was poisoned to death in two types of wastewater tested; Paspalum notatum could not survive in the high concentrated leachate(HCL) and was severely damaged in the low concentrated leachate(LCL): Alternanthera philoxeroides was impaired in HCL, but formed a considerably large biomass in LCL,which was possibly due to that LCL may have efficiency of eutrophication. Vetiveria zizanioides was also hurt by the leachates,but was the least of the four species. The tolerance of the four species to garbage leachate was ranked in the following order V. zizanioides>A.philoxeroides>P.notatum>E.crassipes . Of the two species growing relatively better in wastewater, A.philoxeroides on the whole was superior over V.zizanioides in purifying LCL,especially in purifying total N and nitrate N; but the effects of V.zizanioides in purifying seven kinds of “pollutants” in HCL were all better than that of A.philoxeroides , and the purification of P and COD in LCL by V.zizanioides was, too, better than by A.philoxeroides . Of all seven items measured in the study ammoniac N was the best cleansed, and its purification rate was between 77%~91%. V.zizanioides showed a quite high purification rate for P(>74%). From the research, we suggest that V.zizanioides and A.philoxeroides could act as purifying plants to assist in purifying the high and low concentrated garbage leachates,respectively.

广州李坑拉圾卫生填埋场的渗滤污水含有高浓度的污染物,经过人工净化后仍未达到排放标准,对植物产生毒害。在被观测的4种植物中,水葫芦(Eichhorniacrasipes)在高浓度和低浓度2种污水中均被毒害致死;百喜草(Paspalumnotatum)在高浓度的渗滤液中不能存活,在低浓度中受严重伤害;水花生(Alternantheraphiloxeroides)在高浓度污水中受较重伤害,但在低浓度形成庞大生物体,这可能是污水的“富营养化”所致;香根草(Vetiveriazizanioides)在这2种污水中亦受伤害,但受害程度为4种植物中最轻。在污水中表现相对较好的2种植物中,水花生对低浓度污水的净化效果总体上好于香根草,尤其对总氮和硝态氮的净化效果明显好于香根草,但香根草对高浓度污水中的7种“污物”的净化效果均优于水花生,且对低浓度污水中的磷与COD的净化亦优于水花生。在被观测的7种水质指标中,植物对氨态氮的净化效果最好,净化率在77%~91%之间。此外,香根草对磷也表现出了较强的净化能力,净化率高达70%以上。香根草和水花生可分别作为高、低2种浓度垃圾污水的净化植物来辅助净化污水。
