Description

一种微界面强化超高效废水臭氧处理装置及处理方法 技术领域
本发明涉及废水处理技术领域，具体而言，涉及一种微界面强化超高效废水臭氧处理装置及处理方法。
背景技术
我国水资源短缺，而随着工业的快速发展，废水的种类和数量迅速增加，对水体的污染也日趋广泛和严重，水环境面临异常严峻的形势，威胁人类的建康和安全。在此情况下，国家近年来陆续出台了一系列政策措施，如《水污染防治行动计划》，大力开展水环境整治。水环境治理和保护的关键在于工业领域的废水治理，而工业废水治理的关键在于：1)源头控制，从优化工业过程、提高生产技术水平着手节水、减排；2)不断研究和发展废水净化循环利用或达标排放技术。
化学需氧量(COD cr)是我国废水排放总量控制的主要指标之一，而传统的物化、生化、氧化等工艺对工业废水中难降解有机物的去除率都不高，通常仅有20％-30％的去除率，因此提高工业废水中难降解有机物的去除率，成为亟待解决的难题。
臭氧由于其强氧化性，且反应产物为氧气，扩散进入空气中，不会造成二次污染，是一种绿色环保的氧化剂。臭氧在污水处理领域，尤其是针对废水中高稳定性、难降解有机污染物的处理，得到了广泛应用。
臭氧与污染物反应的方式有直接和间接两种方式。直接反应是臭氧直接氧化污染物，其作用机理主要是基于臭氧的强氧化性，属于选择性反应，且反应缓慢，速率常数很低；间接反应是臭氧在处理过程中产生大量的、活性和氧化性能均更强的羟基自由基(·OH)，从而具备更高的污染物降解去除能力和更快 的反应速率，属于非选择性反应。从在水中臭氧与有机物反应的这两种方式特点来看，臭氧的间接反应具有更重要的意义，特别是在针对难氧化降解的废水处理时，有望成为一种高效去除COD cr的技术。
尽管臭氧氧化技术发展多年，但其在实际的工业废水处理系统中应用较少或效果不佳，归纳其主要问题及原因如下：
(1)目前，常见的制备臭氧技术都是以空气或纯氧为原料，采用电晕放电方法，该过程能耗高、产率较低、臭氧品质波动较大，从而导致臭氧氧化技术的成本居高不下。
(2)臭氧在水中溶解度较低，传统接触设备或方式(曝气)的传质效果不理想，造成气液接触的吸收效率低，限制了参与反应的臭氧浓度，进而限制了污染物处理效果，偏低的臭氧利用率加剧了臭氧氧化技术的成本劣势。
有鉴于此，特提出本发明。
发明内容
本发明的第一目的在于提供一种微界面强化超高效废水臭氧处理装置，该处理装置整体结构简单，通过设置两个处理区对废水进行处理，提高了对废水的氧化处理效果；通过在第二处理区侧壁设置气体出口，第二处理区未反应的臭氧进入第一处理区中继续参与对废水的处理，提高了臭氧的利用率，减少了臭氧的浪费，节约了成本。
本发明的第二目的在于提供一种微界面强化超高效废水臭氧处理方法，该方法操作简单，能够有效提高对废水的净化处理效果，且对臭氧的利用率能达到95％以上，从而节约了废水处理成本。
为了实现本发明的上述目的，特采用以下技术方案：
本发明提供了一种微界面强化超高效废水臭氧处理装置，包括：臭氧发生器和反应塔；所述反应塔中部设置有分隔板；所述分隔板上方为第一处理区， 下方为第二处理区；
所述第一处理区侧壁连接有废水管路；所述第一处理区内设置有第一微界面机组，所述第二处理区内设置有第二微界面机组，
所述臭氧发生器的入口连接有氧气管路，出口分别与所述第一微界面机组和所述第二微界面机组相连；
所述第一处理区内设置有溢流管，所述溢流管穿透所述分隔板连通所述第一处理区和所述第二处理区；所述第一处理区处理后的废水通过所述溢流管进入所述第二处理区中；
所述第二处理区的上部设置有气体出口，所述气体出口与所述第一微界面机组相连以将所述第二处理区顶部的臭氧输送到第一处理区中；所述气体出口高于所述第二处理区内的液面。
现有技术中，臭氧进入反应塔后，由于其本身为气态且在水中溶解度较低，气液接触的吸收效率低，一般只有40％左右的臭氧参与了废水的氧化处理过程，大量臭氧直接从反应塔塔顶排出，臭氧利用率低，严重影响了废水的处理效果，同时，偏低的臭氧利用率加剧了臭氧氧化技术的成本劣势。
为解决上述技术问题，本发明提供了一种微界面强化超高效废水臭氧处理装置，该装置通过设置第一处理区和第二处理区，能够对废水进行两次臭氧处理，从而有效提高了对废水的处理效果；通过设置溢流管，将第一处理区和第二处理区连通，能够使两个处理区内的液面保持平衡，同时第一处理区处理后的废水通过溢流管进入第二处理区中；通过在第一处理区和第二处理区内分别设置第一微界面机组和第二微界面机组，利用微界面机组将臭氧分散破碎成为微米级别的微气泡，提高了臭氧在废水中的溶解度，同时提高了臭氧与废水间的气液接触面积，从而提高了臭氧的利用率，降低了废水处理成本。
优选的，所述第一微界面机组包括第一微界面发生器和第二微界面发生器，所述第一微界面发生器位于所述第二微界面发生器的上方且所述第一微界面发生器与所述第二微界面发生器位于同一直线，所述第一微界面发生器与所 述第二微界面发生器之间设置有第一导流管，所述第一微界面发生器的出口通过所述第一导流管与所述第二微界面发生器相连；所述气体出口与所述第一微界面发生器相连，所述臭氧发生器与所述第二微界面发生器相连。通过设置第一微界面发生器和第二微界面发生器，并利用第一导流管将其进行连接，能够将臭氧进行两次分散破碎，提高对臭氧的分散破碎效果，从而提高臭氧与废水的气液接触面积。
优选的，所述第二微界面机组包括第三微界面发生器、第四微界面发生器和第二导流管，所述第三微界面发生器位于所述第四微界面发生器的上方且所述第三微界面发生器与所述第四微界面发生器位于同一直线，所述第三微界面发生器的出口通过所述第二导流管与所述第四微界面发生器相连；所述第三微界面发生器与所述臭氧发生器相连。通过设置第三微界面发生器和第四微界面发生器，并利用第二导流管将其进行连接，能够将臭氧进行两次分散破碎，提高对臭氧的分散破碎效果，从而提高臭氧与废水的气液接触面积。
优选的，所述溢流管顶部进口高于所述第一微界面机组且位于所述第一处理区内的液面下方，底部出口低于所述第二微界面机组。处理前的废水中含有较多的有机物，相比于处理后的废水密度高，因此，处理后的废水会上浮到顶部，顶部的废水通过溢流管进口溢流到第二处理区中。
优选的，所述废水管路沿竖直方向设置在所述第一微界面发生器与所述第二微界面发生器之间。
优选的，所述第一处理区侧部设置有第一循环管路，所述第一循环管路的入口与所述第一处理区底部相连，出口与所述第一微界面发生器相连。
优选的，所述第二处理区一侧设置有第二循环管路；所述第二循环管路入口与所述第二处理区底部相连；出口与所述第三微界面发生器相连。
优选的，从所述臭氧发生器进入第二反应区的臭氧量大于从所述臭氧发生器进入第一反应区的臭氧量。进一步的，从所述臭氧发生器进入第二反应区的臭氧量与从所述臭氧发生器进入第一反应区的臭氧量的比例为1:9。
优选的，所述第二处理区侧壁设置有液体出口，所述液体出口沿竖直方向位于所述第二微界面机组与所述第二处理区内的液面之间。
优选的，所述第一处理区顶部连接有尾气管路。臭氧与废水反应后生成的氧气以及氧化过程中产生的二氧化碳从尾气管路排出。
在本发明中，废水经废水管路进入第一处理区中，同时，臭氧发生器输送的臭氧进入第一微界面机组中，经微界面破碎成为微米级别的微气泡，与废水混合为气液乳化物，臭氧微气泡与废水接触，对废水中的污染物进行氧化处理；经第一处理区处理后的废水通过溢流管流到第二处理区中；
与此同时，臭氧发生器输送的臭氧在第二微界面机组中分散破碎为微气泡后，继续对废水进行二次处理，处理后的废水经液体出口流出，第二处理区中未参与反应的臭氧经气体出口进入第一处理区中参与对废水的处理。这样既提高了对废水的处理效果，又提高了对臭氧的利用效率，反应体系中对臭氧的利用效率可提高到95％。
实际上，第一处理区中主要进行的是对废水的预处理，也因此其中通入的臭氧远远少于第二反应区中通入的臭氧，这样使第一处理区中废水保持过量，能够提高对臭氧的利用效率，同时对废水进行一次氧化处理；第二处理区是主反应区，其中通入的臭氧过量，在第二微界面机组的分散破碎下分散成为微米级别的微气泡，提高了两者的气液接触面积，从而保证了对废水的处理效果，未参与反应的臭氧从第二处理区上部的气体出口进入到第一处理区中，参与对废水的预处理，从而提高了臭氧的利用效率。
本发明中，一方面通过第一微界面机组和第二微界面机组将臭氧分散破碎成为微米级别的微气泡，提高了臭氧在废水中的停留时间，减缓了臭氧的上升速度，从而延长了臭氧与废水的反应区间，提高了臭氧利用率及废水处理效果，减少了臭氧的浪费；另一方面，产生的臭氧微气泡在废水中破碎时，破碎产生的能量能够将废水中的水分子分解为一个活性氧和一个活性氢氧基，同时臭氧本身在废水中分解为氧气和一个活性氧，这些均对废水中的污染物有氧化效 果。可见，本发明不仅通过采用微界面机组提高了臭氧与废水间的气液接触面积，还利用产生的臭氧微气泡破碎时的破碎能提高了对废水的氧化处理效果，正是通过这种方式，提高了本发明对废水的处理效率。其中，臭氧与水的化学反应式如下：
O 3→O 2+O·
H 2O→HO·+O·
本领域所属技术人员可以理解的是，本发明所采用的微界面发生器在本发明人在先专利中已有体现，如申请号CN201610641119.6、CN201610641251.7、CN201710766435.0、CN106187660、CN105903425A、CN109437390A、CN205833127U及CN207581700U的专利。在先专利CN201610641119.6中详细介绍了微米气泡发生器(即微界面发生器)的具体产品结构和工作原理，该申请文件中记载了“微米气泡发生器包括本体和二次破碎件、本体内具有空腔，本体上设有与空腔连通的进口，空腔的相对的第一端和第二端均敞开，其中空腔的横截面积从空腔的中部向空腔的第一端和第二端减小；二次破碎件设在空腔的第一端和第二端中的至少一个处，二次破碎件的一部分设在空腔内，二次破碎件与空腔两端敞开的通孔之间形成一个环形通道。微米气泡发生器还包括进气管和进液管。”从该申请文件中公开的具体结构可以知晓其具体工作原理为：液体通过进液管切向进入微米气泡发生器内，超高速旋转并切割气体，使气体气泡破碎成微米级别的微气泡，从而提高液相与气相之间的传质面积，而且该专利中的微米气泡发生器属于气动式微界面发生器。
另外，在先专利201610641251.7中有记载一次气泡破碎器具有循环液进口、循环气进口和气液混合物出口，二次气泡破碎器则是将进料口与气液混合物出口连通，说明气泡破碎器都是需要气液混合进入，另外从后面的附图中可知，一次气泡破碎器主要是利用循环液作为动力，所以其实一次气泡破碎器属于液动式微界面发生器，二次气泡破碎器是将气液混合物同时通入到椭圆形的旋转球中进行旋转，从而在旋转的过程中实现气泡破碎，所以二次气泡破碎器 实际上是属于气液联动式微界面发生器。其实，无论是液动式微界面发生器，还是气液联动式微界面发生器，都属于微界面发生器的一种具体形式，然而本发明所采用的微界面发生器并不局限于上述几种形式，在先专利中所记载的气泡破碎器的具体结构只是本发明微界面发生器可采用的其中一种形式而已。
此外，在先专利201710766435.0中记载到“气泡破碎器的原理就是高速射流以达到气体相互碰撞”，并且也阐述了其可以用于微界面强化反应器，验证本身气泡破碎器与微界面发生器之间的关联性；而且在先专利CN106187660中对于气泡破碎器的具体结构也有相关的记载，具体见说明书中第[0031]-[0041]段，以及附图部分，其对气泡破碎器S-2的具体工作原理有详细的阐述，气泡破碎器顶部是液相进口，侧面是气相进口，通过从顶部进来的液相提供卷吸动力，从而达到粉碎成超细气泡的效果，附图中也可见气泡破碎器呈锥形的结构，上部的直径比下部的直径要大，也是为了液相能够更好的提供卷吸动力。
由于在先专利申请的初期，微界面发生器才刚研发出来，所以早期命名为微米气泡发生器(CN201610641119.6)、气泡破碎器(201710766435.0)等，随着不断技术改进，后期更名为微界面发生器，现在本发明中的微界面发生器相当于之前的微米气泡发生器、气泡破碎器等，只是名称不一样。综上所述，本发明的微界面发生器属于现有技术。
本发明还提供了一种微界面强化超高效废水臭氧处理方法，应用上述的处理装置对废水进行处理。
优选的，所述处理方法包括：
氧气转化成臭氧后，经微界面破碎成微米级别的微气泡，臭氧微气泡与废水接触对废水进行净化。
本发明的处理方法操作简单，能够有效提高对废水的净化处理效果，且对臭氧的利用率能达到95％以上，从而节约了废水处理成本。
与现有技术相比，本发明的有益效果在于：
本发明的微界面强化超高效废水臭氧处理装置整体结构简单，通过设置两个处理区对废水进行处理，提高了对废水的氧化处理效果；通过在第二处理区侧壁设置气体出口，第二处理区未反应的臭氧进入第一处理区中继续参与对废水的处理，提高了臭氧的利用率，减少了臭氧的浪费，节约了成本。

为了更加清晰的对本发明中的技术方案进行阐述，下面以具体实施例的形式进行说明。
实施例1
参阅图1，本实施例提供了一种微界面强化超高效废水臭氧处理装置，包括：臭氧发生器170和反应塔；反应塔中部设置有分隔板60；分隔板60上方为第一处理区180，下方为第二处理区10。第一处理区180侧壁连接有废水管 路100；第一处理区180内设置有第一微界面机组，第二处理区10内设置有第二微界面机组；臭氧发生器170的出口分别与第一微界面机组和第二微界面机组相连，入口连接有氧气管路160，反应时，氧气通过氧气管路160进入臭氧发生器170内反应产生臭氧，臭氧分别输入到第一微界面机组和第二微界面机组中分散破碎成微米级别的微气泡后与废水混合，对废水进行处理。为保证处理效果，从臭氧发生器170进入第二反应区的臭氧量大于从臭氧发生器170进入第一反应区的臭氧量。本实施例中，从臭氧发生器170进入第二反应区的臭氧量与从臭氧发生器170进入第一反应区的臭氧量的比例为1:9。
其中，第一微界面机组包括第一微界面发生器90和第二微界面发生器70，第一微界面发生器90位于第二微界面发生器70的上方且第一微界面发生器90与第二微界面发生器70位于同一直线上，第一微界面发生器90与第二微界面发生器70之间设置有第一导流管80，第一微界面发生器90的出口通过第一导流管80与第二微界面发生器70相连；气体出口120与第一微界面发生器90相连，臭氧发生器170与第二微界面发生器70相连。废水管路100沿竖直方向设置在第一微界面发生器90与第二微界面发生器70之间。通过设置第一微界面发生器90和第二微界面发生器70，并利用第一导流管80将其进行连接，能够将臭氧进行两次分散破碎，提高对臭氧的分散破碎效果，从而提高臭氧与废水的气液接触面积。
第一处理区180顶部连接有尾气管路110。臭氧与废水反应后生成的氧气以及氧化过程中产生的二氧化碳从尾气管路110排出。
第一处理区180侧部设置有第一循环管路130，第一循环管路130的入口与第一处理区180底部相连，出口与第一微界面发生器90相连。
在本实施例中，第一处理区180内设置有溢流管20，溢流管20穿透分隔板60连通第一处理区180和第二处理区10；第一处理区180处理后的废水通过溢流管20进入第二处理区10中；具体而言，溢流管20顶部进口高于第一微界面机组且位于第一处理区180内的液面下方，底部出口低于第二微界面机 组。处理前的废水中含有较多的有机物，相比于处理后的废水密度高，处理后的废水上浮到顶部，通过溢流管20进口溢流到第二处理区10中。
继续参阅图1，第二微界面机组包括第三微界面发生器50、第四微界面发生器30和第二导流管40，第三微界面发生器50位于第四微界面发生器30的上方且第三微界面发生器50与第四微界面发生器30位于同一直线上，第三微界面发生器50的出口通过第二导流管40与第四微界面发生器30相连；第三微界面发生器50与臭氧发生器170相连。通过设置第三微界面发生器50和第四微界面发生器30，并利用第二导流管40将其进行连接，能够将臭氧进行两次分散破碎，提高对臭氧的分散破碎效果，从而提高臭氧与废水的气液接触面积。
第二处理区10一侧设置有第二循环管路150；第二循环管路150入口与第二处理区10底部相连；出口与第三微界面发生器50相连。
为提高臭氧的利用率，在第二处理区10的上部设置有气体出口120，气体出口120与第一微界面机组相连以将第二处理区10顶部的臭氧输送到第一处理区180中；气体出口120高于第二处理区10内的液面。
第二处理区10侧壁设置有液体出口140，液体出口140沿竖直方向位于第二微界面机组与第二处理区10内的液面之间。经第二处理区10处理后的水从液体出口140采出。
比较例1
本例与实施例1的不同点仅在于不设置分隔板。
比较例2
本例与实施例1的不同点仅在于第二处理区的气体出口不与第一处理区连接，第二处理区顶部气体直接采出。
比较例3
本例与实施例1的区别在于本例中第一微界面发生器与第二微界面发生器不在同一直线上，第三微界面发生器与第四微界面发生器不在同一直线上，具体如图2所示。
实验例1
以某化工企业的废水为例，分别利用实施例1、比较例1和比较例2的处理装置对废水进行处理。
其中，废水水量100m 3/h，COD为2400mg/L，臭氧投加浓度为100mg/L，测试液体出口采出水的COD，测试结果如下表。
表1测试结果
  COD(mg/L) 去除率(％)
实施例1 40.8 98.3
比较例1 331.2 86.2
比较例2 156 93.5
比较例3 105.6 95.6
从表1中可以看出，本实施例的处理装置能够有效净化废水，去除率能够达到98.3％。其中，比较例1的去除率仅达到86.2％，是因为比较例1中只有一个处理区，进入其中的部分臭氧并未与废水反应就通过顶部的尾气管路排出，臭氧利用率低；而实施例1中则通过设置两个处理区，且第一处理区中仅通入少量臭氧进行预处理，第二处理区上部设置有气体出口，通过气体出口能够将第二处理区中未参与反应的臭氧排入到第一处理区中对废水进行预处理，通过这种方式实现了对臭氧的高效利用，同时提高了对废水的处理效果；比较例2的去除率远低于实施例1，这是由于比较例2中第二处理区未反应的臭氧直接从气体出口采出，影响了臭氧的利用率，因此造成其对废水的处理效果差。比较例3的去除率虽然优于比较例1和比较例2，但是其去除率低于实施例1， 这是因为比较例3中微界面机组的两个微界面发生器不在同一直线上，因此，微气泡在导流管中输送时可能会受到输送路径的影响，冲击力减弱，在二次破碎时的破碎效果较差，其气液接触面积不如实施例1，因此影响了其去除率。
总之，与现有技术的相比，本发明的微界面强化超高效废水臭氧处理装置整体结构简单，能够有效提高对废水的净化处理效果，且能够实现对臭氧的高效利用，从而降低了废水处理成本。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
