摘要

该研究总结了在温暖气候下运行的全面渗滤液处理厂启动硝化过程的必要修订，包括进行动态模拟和动力学表征研究，以确定硝化动力学。在调试后，该装置的工艺温度在运行的前六个月达到高温，未能实现完全硝化。通过在生物反应器缺氧容积内安装表面曝气机，将工艺温度从40℃降至30℃。通过选择合适的曝气容量，除降低活性污泥温度外，总氮去除率达到80%。此外，通过动态模拟和动力学研究，确定了氨氧化细菌（AOB）和亚硝酸盐氧化细菌（NOB）在30°C工艺温度下的最大特定生长速率分别为0.85和0.56天−1。

Identification of Nitrification Kinetics for Activated Sludge Treating Leachate Using Combined Plant Start-up Data and Batch Kinetic Test

The study summarizes the necessary revisions for initiating the nitrification process in a full-scale leachate treatment plant that operates in a warm climate including dynamic simulation and kinetic characterization studies that were conducted to determine the nitrification kinetics. Following its commissioning, the process temperature in the plant reached high temperatures during the first six months of operation and failed to achieve complete nitrification. The process temperature was lowered from 40°C to 30°C with the aid of surface aerators installed in the anoxic volume of the bioreactor. With the selection of appropriate aerator capacity, besides reducing the temperature of the activated sludge, an 80% total nitrogen removal was achieved. Furthermore, as a result of dynamic simulation and kinetic studies, the maximum specific growth rates for ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB) at a process temperature of 30°C were determined to be 0.85 day⁻¹ and 0.56 day⁻¹, respectively, around neutral pH.

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
