Abstract

Results of experimental pilot-scale study of aerobic pre-treatment of the leachate of the Hrybovychi municipal solid waste (MSW) landfill (Ukraine) in batch reactor mode and in semi-continuous mode are presented. The dependencies of key pollution indicators, namely biological oxygen demand, chemical oxygen demand, pH, suspended solids, and total Kjeldahl nitrogen (TKN), during a 30-day periodical aeration process were obtained. The first 15 days treatment was in the batch reactor mode treating an initial volume of raw leachate. The second 15 days treatment was in a semi-continuous reactor mode: 400 L of aerobically pre-treated leachate were pumped to the next treatment stage and consequently the same volume of raw leachate was added in the bioreactor tank. Aerobic biological treatment of Hrybovychi landfill leachate using the developed method achieved significant treatment effects, namely 55.3% of the total Kjeldahl nitrogen, 27% of COD, 70.2% of BOD5 and 66.5% of BODtot. Time dependences of TKN, COD, BOD5, and BODtot are well fitted by simple exponential trends, which correspond to first-order reactions. Landfill leachate, aerobically pre-treated in the pilot-scale treatment unit, can be discharged for final treatment to the bio-plateau or to the wastewater treatment plant.

曝气泻湖技术处理垃圾渗滤液的中试模型研究——以Hrybovychi工厂为例

介绍了在间歇反应器模式和半连续模式下对乌克兰赫里波维奇城市固体废物填埋场渗滤液进行好氧预处理的中试研究结果。在30天的周期性曝气过程中，获得了关键污染指标的相关性，即生物需氧量、化学需氧量、pH、悬浮固体和总凯氏氮（TKN）。前15天的处理是在分批反应器模式下处理初始体积的未经处理的渗滤液。第二个15天的处理是在半连续反应器模式下进行的：将400L有氧预处理的渗滤液泵送到下一个处理阶段，因此在生物反应器罐中加入相同体积的未处理渗滤液。采用该方法对Hrybovychi垃圾渗滤液进行好氧生物处理，处理效果显著，分别占总凯氏氮的55.3%、COD的27%、BOD5的70.2%和BODtot的66.5%。TKN、COD、BOD5和BODtot的时间依赖性通过简单的指数趋势很好地拟合，这对应于一级反应。垃圾渗滤液在中试规模的处理装置中经过需氧预处理，可以排放到生物平台或污水处理厂进行最终处理。

期刊介绍： The Environment and Natural Resources Journal is a peer-reviewed journal, which provides insight scientific knowledge into the diverse dimensions of integrated environmental and natural resource management. The journal aims to provide a platform for exchange and distribution of the knowledge and cutting-edge research in the fields of environmental science and natural resource management to academicians, scientists and researchers. The journal accepts a varied array of manuscripts on all aspects of environmental science and natural resource management. The journal scope covers the integration of multidisciplinary sciences for prevention, control, treatment, environmental clean-up and restoration. The study of the existing or emerging problems of environment and natural resources in the region of Southeast Asia and the creation of novel knowledge and/or recommendations of mitigation measures for sustainable development policies are emphasized. The subject areas are diverse, but specific topics of interest include: -Biodiversity -Climate change -Detection and monitoring of polluted sources e.g., industry, mining -Disaster e.g., forest fire, flooding, earthquake, tsunami, or tidal wave -Ecological/Environmental modelling -Emerging contaminants/hazardous wastes investigation and remediation -Environmental dynamics e.g., coastal erosion, sea level rise -Environmental assessment tools, policy and management e.g., GIS, remote sensing, Environmental -Management System (EMS) -Environmental pollution and other novel solutions to pollution -Remediation technology of contaminated environments -Transboundary pollution -Waste and wastewater treatments and disposal technology
