Description

一种磁-声联合臭氧催化氧化系统及方法 技术领域
本发明涉及污水处理领域，尤其涉及到一种磁-声联合臭氧催化氧化系统及方法。
背景技术
随着我国经济社会的进步，城镇化建设和工业发展导致工业废水和生活污水的排放逐渐增多，并对水体的污染也日趋严重，尤其工业废水排放中，部分含有难降解有机物(B/C小于0.3，或含有有毒物质，难以进行生化处理)不能采用或即便采用生化处理工艺也难以达标排放，必须采用物理化学手段对难降解废水进行预处理或深度处理，提高废水可生化性或进行最终达标排放。
针对臭氧催化氧化系统，目前大多数系统和方法集中在提高催化剂活性、改变气液流向或者改善装置属性来提高臭氧利用率，增加反应效率。而系统性的利用装置和工艺有机结合提高臭氧利用率和处理效率的相关报道较少。
申请人检索到的背景技术包括：
1、通过改变气液流向，由气液顺流改成气液逆流来增加气液混合体和固体催化剂的接触时间(如申请号为200820181029.4的专利文献)；
2、通过增加浮动组件，使得固体催化剂在悬浮作用下与气液混合体共同向上流动，从而增加气液固三相的接触时间(如申请号为201510440580.0的专利文献)；
3、通过在塔内设有内筒，增加隔档从而增加气液固三相在塔中折流次数和流动时间，实现延长催化氧化时间的目的(如申请号201410775077.6的专利文献)；
上述现有技术不同程度存在着以下技术问题：一是气液混合体与固体催化剂的接触时间相对较短，催化氧化深度不够；二是经过一段时间的反应，附有催化剂的载体表面会生成有机膜，如果不及时处理会减少催化剂的使用寿命，提高生产成本。
4、申请号为201410356624.7的专利文献针对传统臭氧催化氧化装置进行了改进，设计了一种改进反应装置，该装置通过导流筒将反应区分为三个区域，改变臭氧和水的流向，并带动催化剂处于循环流化状态，从而增加了催化剂层的空隙率，增加了有机废水在催化剂上的接触时间。
该现有技术存在以下缺点：装置成本较高，活性炭在流动过程中容易堵塞管路，活性炭在三个区域内分散广，在失活换新时增加了清理难度。

步骤五：在气体和液体的共同作用下，提砂管内的催化剂填料与气体、液体剧烈摩擦，填料颗粒之间、填料与无轴螺旋之间产生碰撞，填料表面覆盖的悬浮物进一步被清洗，并随水流、气流上升至分离器；

5.在不降低整体工艺处理量的情况下，通过设置回流管的技术措施提高了催化剂的 处理能力和效率，提高了臭氧利用率。

磁-声联合臭氧催化氧化系统的方法，包括如下步骤：
步骤一：进水管1内的污水与高压溶气水混合后，由布水系统2喷出进入催化剂填料层3中被净化处理；
步骤二：净化后的水一部分排放，一部分通过回流集水系统6进入回流管7，与臭氧在旋涡式水泵9内加压后，形成高压溶气水注入进水管1；
步骤三：在重力作用下，催化剂填料通过第一导砂锥11与反应筒23之间的缝隙进第一导砂锥11与第二导砂锥13之间，在超声波的作用下和高压气体的作用下，催化剂填料表面的覆盖物松散、剥离；超声波由声能转换器12提供；
步骤四：第二导砂锥13下方的高速气流带动催化剂填料进入提砂管15，并在第二导砂锥13下方形成真空，将第一导砂锥11和第二导砂锥13之间的催化剂填料和脱落的表面覆盖，通过第二导砂锥13与反应筒23之间的缝隙吸入第二导砂锥13底部空间A；
步骤五：在气体和液体的共同作用下，提砂管15内的催化剂填料表面覆盖的悬浮物进一步被清洗，并上升至分离器20；
步骤六：被进一步清洗的催化剂填料从分离器20和提砂管15之间的缝隙落入催化剂填料层3，开始新的循环。
进一步的，步骤六中，分离器20内的气泡黏附在悬浮物表面，进入排渣堰槽7，通过排渣管18排出。
工作过程：
来自进水管1的污水与来自回流管7回流的气液混合水汇合后进入布水系统2，在催化剂填料层3中被净化处理。净化后的污水进入出水堰槽4，通过排水管5排放。
污水净化过程中截留的悬浮物，随着填料层下移，通过导砂锥11和反应筒23之间的缝隙进入反应筒23的锥斗，在声能转换器12的作用下，催化剂填料颗粒表面的覆盖物与填料剥离，恢复催化剂活性。通过高压空气通过进气管14，在反应筒23下部的锥斗进入导砂锥13，在导砂锥13和反应筒23下部的锥斗之间形成“真空”，将导砂锥13外的催化剂填料颗粒吸进提砂管15，水、气和催化剂填料颗粒与提砂管15内的无轴螺旋多次碰撞、冲刷，进一步清洗催化剂填料表面覆盖的悬浮物。在分离器20内，气泡黏附在悬浮物表面，进入排渣堰槽17，通过排渣管18排出。恢复活性的催化剂从分离器20和提砂管15之间的缝隙落入到填料层，开始新的循环。
为了增强处理效果，反应筒23内壁设置了磁环22，来自臭氧发生器8的臭氧和回流水通过旋涡式水泵9进行混合，旋涡式水泵9后面的压力表10用于显示泵后压力，系统要求泵后压力0.5Mpa以上。
超声波发生器25外置，所发出的频率为30～40hz。
磁环22电感系数不低于60.0L/N 2，相对磁导率10μo，外部涂环氧涂层。
反应筒顶板19用于支撑反应器20，第一支撑板21和第二支撑板22分别用来支撑提砂管15和排渣管18，支撑架16用来支撑反应筒下端。
