Microorganism immobilization by forming biofilm was considered as an effective way to enhance the degradation efficiency of toxic aliphatic nitrile in the wastewater treatment system.In this work,the
随着传统污水处理的局限性和水质要求的提高，膜生物反应器受到越来越广泛的重视。然而，膜污染问题是制约其快速发展的障碍所在，膜污染主要表现为跨膜压力的升高和产水量的降低。为了降低费用，延长膜的使用寿命，更好的实现MBR应用的拓展，需要采取一系列抗污染策略。研究表明，微生物在膜上的沉积、生长、代谢所产生的生物污染是导致膜通量下降的主要原因，从而，产生淬灭活性的细菌引起了人们的关注。
Bio-energy is a renewable energy that plays an indispensable role in meeting todays ever increasing energy demand.The world is facing an energy crisis as petroleum reserves are being depleted at a fas
活性污泥作为废水处理系统的功能主体，以悬浮填充、附着生长或生物菌膜等方式存在于生化反应器中，并对废水中的污染物基质进行生物降解。其中微生物群落的生理活性直接影响系统的功能稳定和污染物降解效能，了解和预测这些多样的微生物群体在特定生境中的功能特征或对环境胁迫的应激表现，是优化废水处理系统的生物降解进程的关键。利用RNA-Seq高通量测序技术在环境转录组水平上进行活性污泥微生物的生理活性研究，回避了微
With the exploitation of rare earth ore,more and more REEs came into groundwater.This was a waste of resources and could be harmful to the organisms.This study aimed to find an efficient adsorption ma
Background:As flame retardants,polybrominated diphenyl ethers (PBDEs) have been used in a variety of commercial productions for more than four decades.The widely commercial products as mixtures of PBD
研究在污泥膨胀与不膨胀时城市污水处理厂中细菌与噬菌体丰度的差异.分别在5月份和9月份在包含2个AO工艺和1个A2O工艺的两个城市污水处理厂测其活性污泥中的SV,SVI,MLSS,COD,TN,TP,SS,DO等基本指标；对污水样品中的细菌和噬菌体过滤后分别进行DAPI染色和Sybr Gold染色,通过荧光显微镜对其进行计数,获得其丰度；使用SPSS软件处理数据.5月份SV均高达60％,表明污泥膨胀
近年来,抗生素的环境污染与扩散问题已经成为全球关注的热点.畜禽粪便作为抗生素及抗生素抗性基因的重要储库,若未经处理直接施用则具有潜在的生态环境和人类健康风险.本研究采用传统的好氧堆肥方法,对不同来源的鸡粪、猪粪样品中的四环素类抗生素(四环素、土霉素)残留、四环素类抗性细菌、四环素类抗性基因的动态变化进行了追踪研究.结果表明,畜禽粪便中四环素、土霉素的浓度经堆肥处理后分别减少了74.9％～92.3％
Polycyclic aromatic hydrocarbons(PAHs)have been a contaminant of great environmental concern due to their ubiquity,toxicity and recalcitrance properties.Biodegradation is an ideal way to clean up PAHs
Triphenylmethane dyes are aromatic xenobiotic compounds,which are used for textile dyeing and other industrial applications.Most of these dyes are highly toxic to mammalian cells and mutagenic and car
