Abstract

Biological invasions occur when species are moved by human activities from their native range to new areas where they have no evolutionary history and are a major global economic and ecological concern. This paper includes biological treatment of a new activated sludge system that can remove abundant organic matter (OM) in wastewater. The study presents also modelling of organic matter biodegradation process. Factors affecting the biodegradation rate were carried out Viz. the concentration of the organic matter, the mass of activated sludge, the dye content, and the optical density. The results showed that the biodegradation kinetics with time displays an exponential decay. However, the kinetics reaction is well fit by a pseudo second-order equation. After 1 h of treatment, the yields of 93.63 and 92.86% for concentration of 60 and 30 ppm were respectively recorded. UV–Visible spectra and fluorescence spectroscopy were also investigated. Fluorescence spectroscopy was used to characterize municipal waste water at various stages of treatment. A Principal Component Analysis (PCA) has displayed, in agreement with experiments, that the correlation between variables are significant.

荧光光谱法研究废水生物降解过程中顽固性有机化合物的发展

当物种被人类活动从其原生范围转移到没有进化历史的新地区时，就会发生生物入侵，这是一个主要的全球经济和生态问题。本文介绍了一种新型活性污泥系统的生物处理，该系统可以去除废水中丰富的有机物。该研究还提出了有机物生物降解过程的建模。考察了影响生物降解率的因素：有机物浓度、活性污泥质量、染料含量和光密度。结果表明，生物降解动力学随时间呈指数衰减。然而，动力学反应很好地拟合了一个伪二阶方程。处理1 h后，浓度为60 ppm和30 ppm时，产率分别为93.63%和92.86%。紫外可见光谱和荧光光谱也进行了研究。采用荧光光谱法对不同处理阶段的城市污水进行了表征。主成分分析（PCA）显示，与实验一致，变量之间的相关性是显著的。

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.
