摘要： 室温下接种絮状污泥于分别采用梯度进水快速进水和慢速进水方式运行的SBR反应器R1、R2、R3中,人工配水为进水基质,探究进水方式对SBR系统内碳源储存性能和污染物去除效果的影响.结果表明,梯度进水下具有更好的内碳源储存性能和脱氮效果.启动成功后R1内碳源储存率(COD_(in))、同步硝化内源反硝化(SNED)率和TN、COD、TP平均去除率分别为99.69%、81.52%、79.07%、92.35%、96.03%.其中TP平均去除率仅次于R3的98.43%,原因是慢速进水下PAOs对内碳源储存贡献比例(P_(paos))占主体(54.41%),而梯度进水下P_(paos)仅为47.90%.R1污泥浓度为5575mg/L,虽低于R2中的6389mg/L,但其MLSS/MLVSS为0.90,说明梯度进水下颗粒污泥具有较高的生物量.EPS分析结果表明,PS组成成分随着进水方式的改变而改变,梯度进水下含有更高的蛋白质(PN),因此颗粒疏水性更强,颗粒结构更稳定.

摘要： 缺氧/好氧工艺(A/O)与序批式活性污泥法(SBR)是应用最为广泛的猪场废水厌氧消化液好氧处理工艺,但两者的处理性能孰优孰劣,目前尚无定论。基于此,本研究对比了实验室规模的A/O与SBR工艺处理猪场废水厌氧消化液的性能。结果表明:两种工艺直接处理猪场废水厌氧消化液,出水pH值下降至6以下,平均NH_(4)^(+)-N去除率均低于50%,但SBR的NH_(4)^(+)-N去除率略高于A/O。补充碱度后,4个氮负荷(0.02,0.04,0.06,0.08 kg∙kg^(-1)∙d^(-1))下,两种工艺的NH_(4)^(+)-N去除率提高到99%以上,但对COD、TN和TP去除的改善不明显,并且A/O与SBR对COD、NH_(4)^(+)-N、TN、TP去除效果无显著差异。活性试验表明,SBR的氨氧化活性和厌氧氨氧化活性高于A/O,但是反硝化活性要显著低于A/O。Stover–Kincannon模型与试验数据拟合良好(R^(2)>0.9),A/O和SBR对COD、TN、NH_(4)^(+)-N的最大去除负荷(U_(max))分别为7.62、0.28、48.8 g∙L^(-1)·d^(-1)和7.18、0.13、65.4 g∙L^(-1)·d^(-1),说明SBR有利于NH_(4)^(+)-N转化,而A/O有利于COD与TN去除。

摘要： 针对纳米膨润土改性沥青的低温性能缺陷,采用两种SBR作为复合改性剂,对纳米膨润土-SBR复合改性沥青的针入度、软化点和延度进行了系统的实验研究。试验结果表明:随着SBR掺量的增加,纳米膨润土-SBR复合改性沥青的针入度随之减小;软化点逐渐增大,但在SBR的掺量超过6%之后,软化点上升趋势变缓慢;延度随着SBR的掺量的增加先增大后减小,在6%掺量时达到最大。SBR的掺入明显改善了纳米膨润土改性沥青的低温性能。

摘要： 近几年,随着国家各项环保政策的颁布,人们的环境保护意识逐渐增强,污水处理厂提标改造成为趋势。在污水处理厂提标改造过程中,诸多污水处理工艺得到改造,其中,SBR工艺的改造比较典型。本文分析了某污水处理厂生物处理段SBR改造为A^(2)O的工艺设计应用实例。实践证明,改造后处理效果显著,出水稳定达标,这对于现状为SBR工艺的污水处理厂提标改造具有借鉴意义。

摘要： 针对老龄垃圾渗滤液脱氮难题,采用单因素试验和正交试验相结合的方法,选取进水pH、进水C/N(COD/NH3-N)比值、曝气时间3个因素。按照L_(9)(3^(4))正交表进行三因素三水平试验,考察其对老龄垃圾渗滤液氨氮的影响。正交试验结果表明:试验中进水pH、进水C/N、曝气时间均为显著性因素,对垃圾渗滤液氨氮去除率的影响顺序依次为:进水pH﹥进水C/N﹥曝气时间。SBR处理老龄垃圾渗滤液脱氮的最佳条件为:进水pH为8.0,进水C/N为25,曝气时间为6 h。

摘要： 采用SBR反应器对比研究了序批式生物膜-活性污泥复合反应器(HSBR)与活性污泥反应器(SBR)的碳氮去除。结果表明,两反应器在COD、NH_(4)-N去除率方面无明显差异,但HSBR的NH_(4)-N过程去除速率显著高于SBR反应器,且HSBR反应器的TN去除率可达62.95%,高于活性污泥反应器39.3%。HSBR的悬浮污泥和附着污泥的比硝化速率分别为2.14 mgNH_(4)-N/(gTS.h)和1.16 mg mgNH_(4)-N/(gTS.h),比反硝化速率分别为0.16 mgNO_(x)-N/(gTS.h)和1.22 mgNO_(x)-N/(gTS.h),显示HSBR的硝化作用主要集中在悬浮污泥中,而反硝化作用则主要是由生物膜附着污泥完成。

摘要： In order to comprehend viscous sludge bulking, a lab-scale sequencing batch reactor (SBR) wasused through operating under three different phases：sludge activity domestication phase, viscous bulkingsetup phase and maintenance phase. The variations of sludge settleability, nitrogen removal performance andsludge flocs morphology during each phase were investigated. The results show that when pH is in the rangeof 7.5~7.9 and temperature is around 23±1°C, viscous bulking can be easily induced by increasing organicloading rate (OLR) to above 0.50 kgCOD·(kgMLSS·d)-1. Meanwhile, nitrification performance, sludgesettleability and effluent quality were all deteriorated obviously. The average effluent suspended solids (ESS)concentration was increased from 5 mg·L-1to 35 mg·L-1, leading to a sharp deduction of mixed liquidsuspended solids (MLSS). Under viscous bulking condition, sludge volume index (SVI) had a closerelationship with phosphorus removal performance. Nitrification could not proceed completely when OLRwas so large, leading to an obvious nitrite accumulation. The Extracellular Polymeric Substances (EPS) andviscosity were bigger than those under normal condition. Sludge flocs morphology was loose and porous.Nitrification performance can be improved quickly after decreasing OLR, but the viscous bulking induced byhigh OLR can not be inhibited just by decreasing OLR alone. Above all, viscous bulking is an morbiditycondition in activated sludge process which should be avoided to deteriorate sludge settleability, effluentquality and nitrification process.
