2Shifts in microbial community structure and diversity in a MBR combined with worm reactors treating synthetic wastewater显示文摘The chemical oxygen demand(COD) and NH_3-N removal, membrane fouling, sludge characteristics and microbial community structure in a membrane bioreactor(MBR) coupled with worm reactors(SSBWR) were evaluated for 210 days. The obtained results were compared to those from a conventional MBR(C-MBR) operated in parallel. The results indicated that the combined MBR(S-MBR) achieved higher COD and NH_3-N removal efficiency,slower increase in membrane fouling, better sludge settleability and higher activities of the related enzymes in the activated sludge. Denaturing gradient gel electrophoresis was used to analyze the microbial community structures in the C-MBR and the S-MBR. The microbial community structure in the S-MBR was more diverse than that in the C-MBR. Additionally, the slow-growing microbes such as Saprospiraceae, Actinomyces, Frankia, Clostridium, Comamonas,Pseudomonas, Dechloromonas and Flavobacterium were enriched in the S-MBR, further accounting for the sludge reduction, membrane fouling alleviation and wastewater treatment.Jia Liu Wei Zuo Jun Zhang Hui Li Lipin Li Yu Tian 2017Journal of Environmental Sciences2017,29,4:7

4Objective Quantification of Small Motor Sound Quality Based on Psychoacoustic Metrics显示文摘With the widespread application of electrification and intelligence of automobiles,the number of electric devices with small DC motors in automobiles has gradually increased,and the in-terior of electric vehicles is quieter.The sound quality(SQ)of small motor directly affects the pas-senger experience.Therefore,the research on the SQ of small motor is of great significance.In this paper,the objective quantification of small motor sound quality was investigated based on tradi-tional psychoacoustic metrics.The time-frequency characteristics of sound signal was analyzed to quantify the subjective perception caused by the sound of small motor.And a new psychoacoustic metrics of objective evaluation which were suitable for small motor SQ evaluation were proposed,namely specific loudness energy(SLE),specific prominence ratio index(SPRI),relative pitch exceedance(RPE)and tremolo index(TI).Then,two objective evaluation models of small motor SQ were established to characterize the multi-dimensional subjective perception attributes by using multiple linear regression(MLR)and support vector regression(SVR)respectively,which can be used for the prediction and evaluation of the small motor SQ.The results show that the prediction accuracy of the model established by SVR method was higher than that of MLR,and SVR has stronger robustness.The objective evaluation model of small motors SQ established in this study is of great importance for improving the sound quality of small motors.Tao Huang Zhi’en Liu Binyu Zhang Jinyan Bi Lipin Xie 2022Journal of Beijing Institute of Technology2022,31,2:0
