9日上午，Lengo先生一行人抵达科菲科技总部，邓涛总经理代表科菲科技对LEDYA集团友人表示热烈的欢迎。

邓涛先生与 Lengo 先生相识多年， Lengo 先生一直很欣赏邓总在冶金专业的才华与专注。此次应邀来公司访问交流， Lengo 先生饶有兴致地参观了公司办公室、加工厂及研发中心，听取了邓总关于公司的发展历程、旋流电解技术、研发中心实验装置、公司在国内外开展的多个项目的讲解。当回顾公司的创立与 LEDYA 集团的渊源时，邓总和 Lengo 先生更是欢笑起来，现场气氛热烈。

在邓涛总经理带领下， LEDYA 集团参观了公司制造部 , 对于科菲科技的生产设备与对产品的严格把控给予了充分的肯定。

随后，一行人前往公司研发中心进行参观。

期间，邓涛总经理向 Lengo 先生一行人介绍了研发中心先进的研发设备，充分体现了科菲科技在技术研发方面的强大优势。

下午，针对 LEDYA 集团提供的一些矿山情况，公司领导在南湖国际酒店举办讨论会，向来访一行介绍了公司为 LEDYA 集团拟在刚果（金）科卢韦齐建设的冶炼厂提供的初步方案。双方在讨论会上进一步对项目进行交流和探讨。

1.1工作原理

所有的电解技术均建立在电化学基础理论之上，旋流电解技术也不例外。传统的电解技术是将阴阳极放置在缓慢流动或停滞的槽体内，在电场的作用下，阴离子向阳极定向移动，阳离子向阴极定向移动，通过控制一定的技术条件，欲获得的金属阳离子在阴极得到电子沉积析出，从而得到电解产品。

阴极反应：金属离子在阴极得到电子形成金属

Me+(aq)+e- →Me(S)

阳极反应： 阴极得到的电子需要通过阳极失去电子来平衡。阳极有几个可能的反应，最主要的反应是溶液中的水氧化产生氧气，反应如下：

2H2O → O2(g)+4H++4e-

当电解液中的金属浓度降低时，很难保证金属在阴极还原而不发生其它反应。

传统电解技术与旋流电解技术工作原理对比图

在金属浓度较低时最容易发生的化学反应是氢气的产生，如下：

2H+(aq)+2e- → H2(g)

旋流电解技术是基于各金属离子理论析出电位（E¢）的差异，即欲被提取的金属只要与溶液体系中其他金属离子有较大的电位差，则电位较正的金属易于在阴极优先析出，其关键是通过溶液告诉旋流来消除浓差极化等对电解的不利因素，避免了在传统电解过程受多种因素（离子浓度、析出电位、浓差极化、超电位、pH值等）影响的限制，可以通过简单的技术条件生产出高质量的金属产品。

以硫酸铜溶液的电解（电积）过程为例，旋流电解装置中发生的反应如下： 直流电使得电子在阳极（正极）和阴极进行转移。阳极上进行的反应消耗电子（氧化反应），阴极上的反应是得到电子的反应（还原反应）。

2价铜离子在阴极表面被还原成金属铜：

2Cu2+(aq) + 4e-2Cu(s)                   (1)

在阴极上得到的电子必须与在阳极上失掉的电子平衡。阳极上发生的反应可能性有多种，最可能发生的水的析氧反应。

2H2O(l)O2(g) + 4H+ + 4e-                (2)

把反应1和反应2进行归纳，总反应可以表述如下：

Cu2+(aq) + H2O(l)½O2 (g) + 2H+ + Cu(s)      (3)

示意图：

电流效率主要由除了铜在阴极还原的反应之外的其它反应来决定。理想状态下，在阴极发生的反应是铜离子在阴极还原形成铜金属。如果这是唯一的一个阴极反应的话，电流只是用于沉积铜离子，此时电流效率为100%

当电解液中的铜浓度降低时，很难保证铜在阴极还原而不发生其它反应。在铜浓度较低时最容易发生的化学反应是氢气的产生，如下：

2H+(aq)+2e- → H2(g)

1.2旋流电解装置概述

旋流电解装置是集工艺装备、电气设备与控制系统于一体的综合系统。工艺过程是电解溶液通过溶液输送泵从贮槽送到按设计排列与布局的旋流电解槽内，溶液在装置体系内部进行循环，有价金属离子通过选择性电解的作用从电解溶液中分离出来并吸附至阴极板上。桶状产品通过专用产品采集装置进行采集，粉体产品通过专用粉体采集系统自动进行。桶状产品进一步通过后序配套的产品加工装置制成板体产品。与之配套的能够在高电流密度、高效率运作的智能电源分配装置系统和综合控制系统，采用冗余硬件系统和全数字软件式高精度触发调节控制器，双工热备用，抗谐波干扰、抗强磁场干扰，与总控PLC系统通讯共同完成电解电流的智能控制。结合自动控制系统专利技术，实现生产过程中对流量、液位、温度等的自主检测，确保规模化生产中准确性与可靠性操作。

这是该标准第二次公开征求意见。第一次征求意见稿于2008年3月向社会公布，距今已时隔五年。该标准的编制工作于2003年启动，目的是为防治环境污染、维护生态平衡、保护人体健康，控制有色金属工业污染物排放，促进有色金属工业生产技术装备和污染控制技术的进步。

在编制工作启动的十年间，包括锡、锑、汞在内的有色金属产业发展迅猛。由于缺乏国家层面的污染物排放标准，有色金属产业已成为重要的环境污染源，且污染事故频发。

征求意见稿对锡、锑、汞采选及冶炼工业企业生产过程中水污染物和大气污染物排放限值、监测和监控要求等作出了明确规定。

征求意见稿尤其明确了“容易发生严重水污染问题而需要采取特别保护措施的地区”和“容易发生严重大气环境污染问题的地区”的锡、锑、汞及其化合物在污水和废气中的排放限值。这些排放值标准在一定程度上填补了现有标准的空白，如《污水综合排放标准》（GB 8978-1996）仅规定了污水中总汞的排放标准，并未涉及锡、锑的排放含量。

中国是全球最大的锡生产国，锑矿、汞矿的总保有量也分居世界第一、第三。中国同时也是这三种有色金属的主要消费国和排放国之一，仅汞排放就占全球排放总量的四分之一。

2013年10月，中国政府代表团将出席由联合国环境规划署举办的《水俣公约》签约会议。《水俣公约》是全球首个具有法律约束力的限汞公约，公约要求缔约国在15年内逐步淘汰所有汞矿并在公约生效三年内减少甚至禁止使用汞。 除行业特征污染物外，征求意见稿还对氨氮、COD（化学需氧量）、六价铬等18项水污染物和二氧化硫、氟化物、颗粒物等11项大气污染物做出了限额规定。

中国正在面临有色金属工业发展所带来的环境和健康挑战。国家已采取相应措施，加速有色金属工业的减排工作。根据《重金属污染综合防治“十二五”规划》规定，到2015年，重点区域铅、汞、铬、镉和类金属砷等重金属污染物的排放，比2007年削减15%。

传统的工艺包括物理，化学，生物方法，它们可以有效的降解大部分污染物（除难降解物质），排入环境之前利用上述技术提高水质。然而，在经过这种处理工艺后，其废水中仍有大量的残留污染物。因此，有必要尽可能多的去除这些废水中的污染物，有效解决有机化合物或其它还原性污染物造成的COD浓度高、难于生化处理等问题。

针对现有技术中存在的上述问题，本公司自主研发了密闭式活塞流电催化装置及处理方法，它有效解决有机化合物或其它还原性污染物造成的COD浓度高、难于生化处理等问题，广泛适用于水处理及其他环保领域。

该技术优势：1）短流程、无需添加化学药剂的印染废水深度处理及回用的电催化氧化技术及其处理系统集成；2）与电催化氧化技术相匹配的超滤+反渗透为组件的废水回用及膜浓水达标排放技术。

2) 高效活塞流电催化氧化反应器的结构形式的设计与研发；与之相匹配的供液、供电系统及电控、装配等其它辅助系统的研发；进行印染废水电催化处理系统整体的集成与优化，确定最优的电催化工艺技术参数；

3) 与电催化出水深度处理相匹配的超滤、反渗透等工艺条件的确定；

4) 分别针对电催化氧化、超滤、反渗透等单元处理的最优条件，进行系统装备的设计，包括废水进排系统、配电系统、控制系统等，使之满足客户要求。

公司产品

旋流电解电絮凝技术具体原理：

（1）Fe2+与Fe3+的循环还原氧化作用

电解过程中，铁阳极氧化电解，使得Fe被氧化为Fe3+。从铁的电极电位可以知道，在金属活动顺序表中排在铁后面的金属有可能被铁置换出来而沉积在铁的表面上。

同样，其他氧化性较强的离子或化合物也会被铁或亚铁离子还原成毒性较小的还原态。有文献介绍，铁的还原能力可使某些有机物还原成还原态。硝基苯可被活性金属还原成胺基就是其中一例，还原后的胺基有机物色淡，且易被微生物氧化分解，使废水中的色度得以降低，可生化性提高，为进一步的生化处理创造了条件。

（2）物理吸附

由于Fe3+极易水解生成氢氧化铁胶体沉淀，在弱酸性溶液中，氢氧化铁胶体丰富的比表面积显出较高的表面活性，能吸附多种金属离子及有机分子，能促进金属和有机分子的去除。在酸性条件下，Fe2+与Fe3+是很好的絮凝剂，把溶液pH调至碱性会形成Fe(OH)2和Fe(OH)3絮凝沉淀。由于电解过程有电荷配合作用，使得生成的Fe(OH)3胶体絮凝剂的吸附能力高于一般药剂水解得到的Fe(OH)3吸附能力。这样，废水中原有的悬浮物，通过电解反应产生的不溶物以及有机物降解大分子均可被其吸附凝聚。

（3）高电流密度电场对有机物大分子的降解作用

有学者研究发现，在高电流密度电场的作用下，有机物大分子会发生降解反应，因此会出现钴离子从Co、Ni螯合物结构中解脱出来，并且在二价铁的配合作用下，这种反应的速度会加快。
