Zn-air batteries(ZABs)as a potential energy conversion system suffer from low power density(typically≤200 mW·cm^(−2)).Recently,three-dimensional(3D)integrated air cathodes have demonstrated promising performance over traditional twodimensional(2D)plane ones,which is ascribed to enriched active sites and enhanced diffusion,but without experimental ***,we applied a bubble pump consumption chronoamperometry(BPCC)method to quantitatively identify the gas diffusion coefficient(D)and effective catalytic sites density(ρEC)of the integrated air cathodes for ***,the D andρEC values can instruct consequent optimization on the growth of Co embedded N-doped carbon nanotubes(CoNCNTs)on carbon fiber paper(CFP)and aerophilicity tuning,giving 4 times D and 1.3 timesρEC over the conventional 2D Pt/C-CFP *** a result,using the CoNCNTs with half-wave potential of merely 0.78 V ***(Pt/C:0.89 V ***),the superaerophilic CoNCNTs-CFP cathode-based ZABs exhibited a superior peak power density of 245 mW·cm^(−2) over traditional 2D Pt/C-CFP counterparts,breaking the threshold of 200 mW·cm^(−2).This work reveals the intrinsic feature of the 3D integrated air cathodes by yielding exact D andρEC values,and demonstrates the feasibility of BPCC method for the optimization of integrated electrodes,bypassing trial-and-error strategy.

针对单一硫基质驱动自养反硝化性能的缺陷,采用单质硫(S^(0))与天然铁硫矿石(FeS、Fe_(1-x)S、FeS_(2))两种矿物作为生物填料,构建3组复合硫基质填充床反应器(B1、B2、B3),探究了启动与稳定运行期间反应器对市政尾水深度脱氮除磷的效果与微生物群落结构的特征。结果表明,3组反应器均表出现较高的脱氮性能,NO_(3)^(-)-N去除率均随反应器水力停留时间(HRT)的延长而提高,当反应器HRT分别为1h(B1)、12h(B2)和9h(B3)时,均实现20mg/L NO_(3)^(-)-N完全去除。PO_(4)^(3-)-P与脱氮过程中产生的铁离子形成铁磷沉淀物而被去除,且PO_(4)^(3-)P的去除率与脱氮效果呈正相关。复合硫基质反应器的SO_(4)^(2-)/NO_(3)^(-)低于单一硫基质自养反硝化系统,硫酸盐产生量相应降低,且pH保持在6.3以上,无需添加pH缓冲剂。微生物群落结构分析表明,Thiobacillus(硫杆菌属)和Ferritrophicum(铁氧化菌属)是3组反应器中硫自养反硝化菌的优势菌属,在B1、B2和B3反应器的相对丰度分别为16.07%和31.24%、30.07%和50.19%以及30.20%和11.62%。复合硫基质提高了微生物群落丰度和物种多样性,从而表现出良好的脱氮除磷效果。

To enhance phosphorus removal and make the effluent meet the strict discharge level of total phosphorus (TP, 0.5 mg/L), flocculant dosing is frequently applied. In this study, the performance of aluminum sulfate dosing in a University of Cape Town Membrane Bioreactor (UCT-MBR) was investigated, in terms of the nutrients removal performance, sludge characteristics and membrane fouling. The results indicated that the addition of aluminum sulfate into the aerobic reactor continuously had significantly enhanced phosphorus removal. Moreover, COD, NH4+^-N and TN removal were not affected and effluent all met the first level A criteria of GB18918-2002. In addition, the addition of aluminum sulfhte had improved the sludge activity slightly and reduced transmembrane pressure (TMP) increase rate from 1.13 KPa/d to 0.57 KPa/d effectively. The alleviation of membrane fouling was attributed to the increased average particle sizes and the decreased accumulation of the small sludge particles on membrane surface. Furthcnnorc, the decline of extracellular polymeric substance (EPS) concentration in mixed sludge liquid decreased its accumulation on membrane surface, resulting in the mitigation of membrane fouling directly.

Effect of different carbon sources on purification performance and change of microbial community structure in a novel AzN-MBR process were investigated, The results showed that when fed with acetate, propionate or acetate and propionate mixed （ 1 ： 1 ） as carbon sources, the effluent COD, NH4＋- N, TN and TP were lower than 30, 5, 15 and 0.5 mg-L-1, respectively. However taken glucose as carbon source, the TP concentration of effluent reached 2.6 1 mg.L-1. Process analysis found that the amount of anaerobic phosphorus release would be the key factor to determine the above effectiveness. The acetate was beneficial to the growth of Candidatus Accumulibacter associated with biological phosphorus removal, which was the main cause of high efficiency phosphorus removal in this system. In addition, it could eliminate the Candidatus Competibacter associated with glycogen-accumulating organisms and guarantee high efficiency phosphorus uptake of phosphorus accumulating organisms in the system with acetate as carbon source.
