摘要

Abstract <section xml:id="jctb5520-sec-0001" numbered="no"> <title type="main">BACKGROUND >Ultrafiltration is used as tertiary treatment in wastewater treatment plants (WWTP) for wastewater reclamation. However, membrane fouling is the main drawback of the process. In this work a new effluent organic matter fractionation procedure with adsorption resins (XAD‐8, XAD4 and IRA‐958) has been applied without recovering the adsorbed fractions. In this way, strong and weak hydrophobic and charged hydrophilic substances of the dissolved organic matter (DOM) were removed for further ultrafiltration, in order to know the most fouling fraction. For this, secondary effluents of two WWTP and two membranes with different molecular weight cut‐offs (100 kDa and 3 kDa) were used in ultrafiltration experiments in a laboratory plant. </section> <section xml:id="jctb5520-sec-0002" numbered="no"> <title type="main">RESULTS >The hydrophobic substances (especially the strong hydrophobics) predominated over the hydrophilic compounds. Membrane fouling was higher for the membrane with the highest molecular weight cut‐off (100 kDa). Thus, flux decline was around 25–47% higher than that measured for the 3 kDa membrane. The charged hydrophilic substances (CHi) were identified as the most fouling compounds with 100 kDa membrane. Reversible fouling was predominant. </section> <section xml:id="jctb5520-sec-0003" numbered="no"> <title type="main">CONCLUSIONS >The proposed fractionation system enabled determination of the contribution of the different fractions to the DOM. ? 2017 Society of Chemical Industry </section> </abstract> </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 =“JCTB5520-SEC-0001”编号=“否”> <标题类型=“main”>背景</标题> >超滤用作废水处理厂(WWTP)中的第三次处理,用于废水填海。然而,膜污垢是该过程的主要缺点。在这项工作中,已经施加了具有吸附树脂(XAD-8,XAD4和IRA-958)的新的污水有机物分级步骤,而不回收吸附的级分。以这种方式,除去溶解有机物质(DOM)的强且弱的疏水性和带电亲水性物质以进一步超滤,以了解最污垢的级分。为此,在实验室植物中的超滤实验中使用两种WWTP的二次污水和两个具有不同分子量截止(100kDa和3kDa)的膜。</ p> </ section> <section XML:ID =“ JCTB5520-SEC-0002“编号=”否“> <标题类型=”main“>结果</标题> >疏水性物质(特别是强疏水性)以亲水化合物占主导地位。膜的膜污染较高的分子量截止最高(100kDa)。因此,助焊剂下降比3kDa膜测量的助焊剂下降约为25-47%。将带电的亲水性物质(CHI)鉴定为具有100kDa膜的最污垢化合物。可逆污垢是主要的。</ p> </ section> <section XML:ID =“JCTB5520-SEC-0003”编号=“否”> <标题类型=“main”>结论</ title> >提议分馏系统使能确定不同分数对DOM的贡献。还2017年化学工业协会</ p> </段> </摘要> </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5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=Ferrer‐Polonio Eva&option=202" target="_blank" rel="nofollow">Ferrer‐Polonio Eva;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=McCabe Mandy&option=202" target="_blank" rel="nofollow">McCabe Mandy;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Mendoza‐Roca José A&option=202" target="_blank" rel="nofollow">Mendoza‐Roca José A;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Vincent‐Vela María‐Cinta&option=202" target="_blank" rel="nofollow">Vincent‐Vela María‐Cinta;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Instituto de Seguridad IndustrialUniversitat Politècnica de ValènciaValència Spain;</p> <p>Instituto de Seguridad IndustrialUniversitat Politècnica de ValènciaValència Spain;</p> <p>Instituto de Seguridad IndustrialUniversitat Politècnica de ValènciaValència Spain;</p> <p>Instituto de Seguridad IndustrialUniversitat Politècnica de ValènciaValència Spain;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/180.html" title="生物工程学(生物技术)">生物工程学(生物技术);</a><a href="https://www.zhangqiaokeyan.com/clc/20827.html" title="生物化学过程">生物化学过程;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=wastewater&option=203" rel="nofollow">wastewater;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=fouling&option=203" rel="nofollow">fouling;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=chemical analysis&option=203" rel="nofollow">chemical analysis;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=ultrafiltration&option=203" rel="nofollow">ultrafiltration;</a> </p> <div class="translation"> 机译:废水;污垢;化学分析;超滤;
