摘要

Abstract <section xml:id="jctb5368-sec-0001" numbered="no"> <title type="main">BACKGROUND >This study evaluated the microbial behavior of activated sludge systems operated with an active heterotrophic biomass inflow. The evaluation focused on the possibility of sludge minimization. Thus, related process stoichiometry was derived on the basis of mass balance for essential parameters. </section> <section xml:id="jctb5368-sec-0002" numbered="no"> <title type="main">RESULTS > Stoichiometric relationships showed that the reactor holds a larger amount of biomass without the controlling impact of the sludge age, which decreases the magnitude of microbial growth compared with endogenous decay. Consequently, the observed yield, Y <sub>OBS</sub> becomes much lower than what may be observed in conventional activated sludge systems. This stoichiometry exactly defines the microbial basis of the OSA ( <fi>oxic/settling/anaerobic)</fi> system and identifies the interchange stream connecting the anaerobic reactor to the aerobic main reactor as the source of the active biomass inflow. Therefore, biomass inflow, largely overlooked in related studies, offers a novel microbial perspective for the merit of the OSA process in minimizing sludge generation. </section> <section xml:id="jctb5368-sec-0003" numbered="no"> <title type="main">CONCLUSION > The impact of lower Y <sub>OBS</sub> , while explaining lower active biomass production, cannot be extrapolated to cover inert particulate COD fractions, namely a similar reduction in the initial inert COD and the residual particulate microbial products. Future studies should be directed to explore the fate o </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract XMLNS =“http://www.wiley.com/namespaces/wiley”type =“main”xml：lang =“en”> <title type =“main”>抽象</ title> <section XML：ID =“JCTB5368-SEC-0001”编号=“否”> <标题类型=“main”>背景</标题> >本研究评估了用活性异养生物质流入操作的活性污泥系统的微生物行为。评估专注于污泥最小化的可能性。因此，基于基本参数的质量平衡导出相关过程化学计量。</ p> </段> <章节XML：ID =“JCTB5368-SEC-0002”编号=“否”> <标题类型=“main “>结果</标题> >化学计量关系表明，反应器保持较大量的生物质，而不控制污泥年龄的影响，这与内源衰减相比降低了微生物生长的大小。因此，观察到的产率Y <Sub> OBS </ sub>远远低于传统活性污泥系统中可能观察到的产率。该化学计量恰好地定义了OSA（<FI>沉降/厌氧/厌氧）</ FI>系统的微生物基础，并识别将厌氧反应器连接到有氧主反应器的交换流作为活性生物质流入的源。因此，生物质流入在很大程度上被忽视在相关研究中，为OSA工艺的优点提供了一种新的微生物视角，以最小化污泥产生。 </ p> </ section> <section XML：ID =“JCTB5368-SEC-0003”编号=“否”> <标题类型=“main”>结论</ title> >下Y <sub的影响> OBS </ sub>，同时解释较低的活性生物质生产，不能推断以覆盖惰性颗粒鳕鱼级分，即初始惰性COD和残留颗粒微生物产品的类似降低。应该被引导未来的研究探索命运o </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-33908/'>《Journal of Chemical Technology & Biotechnology》</a> <b style="margin: 0 2px;">|</b><span>2018年第2期</span><b style="margin: 0 2px;">|</b><span>共7页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=All?
