Description

一种通过电化学电极设备处理水的工艺
本发明涉及被污染水处理技术领域，尤其是涉及一种通过电化学设备处理废水的工艺。使用此发明可以几乎完全破坏废水中存在的不良溶解物，这些溶解物可能是有机的或者无机的，处理后的水中含有低或非常低含量的上述不良溶解物的产水。环境中的有毒有害有机物，特别是可能影响人体健康的物质，已经成为一个越来越受关注的问题。一种叫做“高级氧化处理”(AOP)的特殊水处理工艺在去除：含有有毒有机物和有毒无机物的饮用纯净水、自来水、地表水、被污染的地下水、经过处理后的市政废水、工业废水的处理方面变得具有竞争优势。“电化学高级氧化工艺(EAOP)就是AOP衍生的众多工艺中的一种。本发明涉及到一种在EAOP工艺中控制电源的方法，此工艺可以提高处理效果并显著的提高此工艺的性价比。
本发明的有益效果可以总结如下：
1)新工艺的第一个优势是，相比其他可去除和破坏不良溶解物的水处理工艺，它的建造成本和运行成本更低；
2)新工艺的第二个优势是，它能可靠的处理进水产出含有低浓度或者极低浓度所有种类或绝大多数种类溶解有机物的产水；
3)新工艺的第三个优势是，其处理后的废水所含氨氮的浓度非常低；
4)新工艺的第三个优势是，其处理后的废水中特定几种无机物的浓度非常低，如硫化物和氰化物。
5)新工艺的一个目标是，在不需要任何进一步处理的条件下，将高浓度废水中上述不良溶解物破坏，使其浓度降低到可达标排放的标准以内，从而可以直接排放到环境中；
6)新工艺的一个目标是，电化学电极运行时在任何条件下都能够保证提供 充足的羟基自由基；
7)新工艺的一个目标是，它不需要“严格控制”，它可以适应进水水质的变化；
8)新工艺的一个优势是，它的效率极高，其能耗比其他相似的电化学氧化工艺低很多。
本发明其他重要的目标、特性以及其他的优势将通过下文详细描述，附加说明和附带图纸进一步展示。
附图说明：
为了让读者更为完整的理解本发明，以及本发明新的特性和优势，请结合参考以下附图：
图1为本发明新的废水氧化工艺应用于不同领域的不同进水的通用流程图；
图2为本发明工艺中的电化学电极的电源供电图；
图3为本发明新的废水氧化工艺应用于不同领域的不同废水的另一种可以备选的通用流程图。
上述图纸仅为示范，其包含的处理因素可能根据实际情况被省略或添加。申请人试图使用图纸能够至少展现出对于理解本发明的各个方面特点的重要元素。但在具体的特定环境下，多种其他的工艺步骤也可能被使用，以构成一个完整的废水处理系统。
图1：为一个工业废水作为进水应用本氧化工艺的总流程图。含不良溶解物的进水10被储存于水箱12中。此高浓度废水接着被打入泵20的入口，接着到电化学电极30的入口。在高浓度废水到达电化学电极入口前，氧气22被注入到进水中以提高废水中溶解氧的浓度。电化学电极30包括最少有2片使用掺硼金钢石(BDD)材料加工的电极板,布置按照可使进水从两个电极板中流过并充 分接触两个电极板。通常来讲，电化学电极会含有几对平行排列的掺硼金刚石电极板，废水可平行流过。电源40与电化学电极连接，通过电极间的电流依据图2所述控制，电流通过电极板后与进水接触。当被部分处理的进水流出电化学电极后，将回流到水箱12中。此进水再循环到电化学电极中数次，直至不良溶解物的浓度降低到要求值，此时电化学电极的水泵断电，水箱中的液体被送入排水口16.破坏不良溶解物的速度可以通过增加电化学电极的数量。在系统中增加第二个电化学电极如图中虚线所示。水流在电化学电极内循环的过程中，水温会升高。冷却水14被送入水箱的热交换器中去除热量并维持进水温度在要求的值。
图2：为应用于本发明一个实例中加入到电化学电极上电流的电路图，它显示了加在电化学电极上电流电路控制的流程图。此电路图的关键特性可描述为：
CC1:时间点T0和T1之间，在所述电化学模块上施加一段时间的恒定电流；所述恒定电流ICC1的大小可由多种方法确定,甚至仅为经验估计；
倒极:在时间T1的CC1阶段，将加在所述电化学电极上电流的正负极进行倒极；
CC2:时间点T2和T3之间，在所述电化学电极上施加一段时间的恒定电流；供应到模块的电流值等于MF x ICC1,MF是一个调整系数,由上一个供电程序循环中读取的电势差值与规定数值比较计算得出；
倒极:在时间点T3的CC2阶段，将加在所述电化学电极上电流的正负极进行倒极；
在第二次电极倒极之后，重复执行上述流程。多次重复，直到将不良溶解物降低到要求的值。
图3：为另一个工业废水作为进水应用本氧化工艺的总流程图：含不良溶解 物的进水50被送入进水箱51中。这些进水接着被泵60送到电化学电极70的入口。在泵出口氧气61被注入到进水中以提高溶解氧的浓度。电化学电极70包括至少包含2片使用掺硼金钢石(BDD)加工的电极板,按照能使进水从两个电极板间流过并充分接触两个电极板的方式设置。通常来讲，电化学电极会含有几对电极板，在进水流过的通道两侧平行排列。电源90与电化学电极连接，通过电极的电流依据图2所述控制通过电极板与进水接触。当进水通过电化学电极后，部分被处理的进水中需要注入氧气以保证废水中的溶解氧有足够浓度，接着再将进水送到另一个电化学电极71的入口。电化学电极71和电化学电极70相似，被连接到电源91上，电源91的控制方式与电源90完全一样。当流出第二个电化学电极后，进水又被打入相似的电化学电极72进行处理，直至将不良溶解物降低到可排放值以下，并被从排放出口100处排出。电化学电极72和电化学电极70相似，被连接到电源92上，电源92的控制方式完全与电源90相同。额外的氧气投加63和泵64按要求安装，以维持整个系统的溶解氧浓度充足。随着进水通过每个电化学电极，其温度会升高。在系统中需要安装热交换器80，降低废水的温度。
