Description

用于工业废水深度处理的内循环臭氧接触反应塔 技术领域
本发明涉及一种接触反应塔，更具体的说是用于工业废水深度处理的内循环臭 氧接触反应塔。
背景技术
臭氧是一种强氧化剂， 对水中有机物有强烈的氧化降解作用， 可将复杂的有机 物转化成为简单有机物， 实现脱色、 脱臭、 降 COD和提高可生物降解性等。 多 余的臭氧可自行分解为氧气，不产生二次污染。因为臭氧与有机物反应时速度快、 效果好、 无二次污染并且可就地生产， 原料易得、 使用方便、 技术设备可靠， 目 前在工业废水处理中应用越来越多， 主要用于废水的深度处理， 具有双重作用： 一是保证污水达标排放， 二是实现中水回用， 以达到水资源的循环利用。
目前水处理中使用的臭氧主要以空气为原料制造，但臭氧发生器生产的臭氧化 空气中臭氧只占 0.6%~1.2% (体积）。 根据气态方程及道尔顿分压定律知， 臭氧 的分压也只有臭氧化空气压力的 0.6%~1.2%。 当水温为 25°C时， 将臭氧化空气 加入水中， 臭氧的溶解度只有 3~7mg/L。 因此， 使臭氧化空气与水充分接触、 提 高臭氧溶解度和气水混合效率是提高臭氧处理效果的关键。
水处理中臭氧化空气和水在专门的气水混合装置中进行接触与混合，完成对污 染物的处理，其中接触面积、时间、臭氧浓度、压力等都是混合效率的决定因素。 目前， 臭氧与水的混合方法主要有以下几种： （1 )曝气法： 这是一种传统的简便 方法， 带有一定压力的臭氧气通过微气泡扩散器形成微小气泡与水充分接触， 气 泡越小， 水深越大， 接触时间越长， 效果越好； （2)射流法： 也称文丘里法， 是 利用水在管道中流动时通过装置变径加快流速形成负压吸气，通入的臭氧与水在 管路中混合，射流法效率较高，但安装设计与要求应相当严格； （3 )涡轮负吸法： 这种方式是通过水泵吸程加装气路， 在供水时形成负吸将臭氧带入水中， 效率较 高， 其原理与文丘里法基本相同， 也广为采用， 其安装要求与文丘里法也大致相 同， 需要特别注意的是气量控制， 气量大时会影响水泵供水； （4)反应塔法： 这 种方法是通过一个较高的装置塔， 将水由高处喷下形成雾状， 将臭氧化气体自设 置在塔底部的微孔扩散设备扩散成微小气泡上升， 与水流形成逆行， 使臭氧气与 水充分接触形成臭氧水， 此方式分无填料和有填料两种， 效果很好， 但成本造价 较高， 且填料容易被堵塞。 此外， 研究者也不断提出了改进方法， 以提高臭氧在 水中的溶角牟度。 H. Fumio (Development of high concentration ozone water machine [J]. Ishikawajima - Harima Engineering Review (Japan), 1996, 36 (3): 159- 164.)石开制 了高浓度臭氧水制造机，臭氧浓度达到 6mg/L。R. Michel Meyer (R. Michael Meyer, Angelo L. Mazzei. Side stream injection with high efficiency venturi and radial mixing nozzle. Proceedings of the 14th Ozone World Congress, Dearborn, Michigan, U.S.A., 1999.527-538.)等人做了臭氧溶解效率研究， 采用射流器和喷嘴相结合的 方法， 在臭氧质量浓度为 128 g/m3时， 水溶液臭氧质量浓度达到 4.8 mg/L， 其溶 解效率达到 75%。张芝涛等 (张芝涛， 鲜于泽， 宗旭等. 臭氧溶解理论实验研究 [J]. 东北大学学报（自然科学版)， 2002, 23 (10): 1016 - 1019.)利用高浓度臭氧水发 生系统，对影响臭氧溶解的因素进行了实验研究，结果表明，高浓度的臭氧气体、 较低的气液体积比以及较高的系统运行压力， 有利于提高臭氧溶解效率。时文生 (ZL 01113892.0)公开的发明专利中提出以一段变径管道取代扩散模式的氧化塔、 罐及其管网， 获得超常的传质速率， 处理效果突出而臭氧用量倍减， 然而这种方 法也存在缺陷， 并不适合处理流量大的工业废水。

下面结合附图进一步说明本发明。
用于工业废水深度处理的内循环臭氧接触反应塔， 中心筒 2内的水在空气管 4 的曝气提升作用下进入提升管 5， 从提升管 5上端开口出来后与反应塔总进水管 3的进水一起进入中心筒进水管 8， 由上至下流入反应塔， 臭氧化空气由中心筒 进水管 8下方的微孔扩散器 9释放， 由下至上与进水进行初步的逆流接触； 随后 进水从中心筒进水管 8流出， 通过穿孔配水壁 11流至反应塔外筒 1， 臭氧化空 气从进气管 10进来通过微孔扩散器 9释放， 水气一起向上流经外筒 1内的填料 区 12， 较高的上升流速可形成良好的紊流状态， 臭氧化空气可充分溶解， 水气 进行充分接触和反应； 气水流过填料区 12后， 部分出水从中心筒 2上的回流窗 13 进入中心筒 2， 然后通过空气提升形成内循环， 其余出水从反应塔总出水管 14流出反应塔， 剩余臭氧通过导气管 17排至大气中， 至此完成一个周期运行。 当进水污染物浓度较高时， 可通过增加空气量提高内循环量， 以降低对反应塔造 成的冲击负荷， 并在短期内延长反应时间， 保证出水水水质。在填料区下方和中 间设有冲洗填料的布气装置 15和冲洗填料的布水装置 16， 可对填料进行冲洗， 避免填料区堵塞影响气水混合效能， 冲洗时反应塔总进水管 3中的单向阀 18可 避免水气进入， 影响冲洗效果， 冲洗时关闭排水管， 冲洗水由冲洗排水管 19排 出。 以下实施例中所用的内循环臭氧接触反应塔中试装置基本结构如上所述。 实施例 1 :
在某维生素 C 厂建立一个内循环臭氧接触反应塔中试装置， 材质为不锈钢。 反应塔内径为 1.5 m， 塔高为 9 m， 中心筒内径为 0.6 m， 中心筒高为 8 m， 中心 筒顶盖距反应塔顶盖 0.4 m， 中心筒底板距反应塔底 0.6 m。中心筒内设两根提升 管， 内径为 52 mm， 每根提升管内装一根微孔曝气管， 中心筒中央为进水管， 内 径为 200 mm， 距反应塔底部 0.2 m， 其正下方装有微孔曝气器。开孔配水壁高度 为 0.6 m， 壁上开孔的孔径为 20 mm， 间距 50 mm。 在反应塔外筒底部装有微孔 曝气器。 填料区的填料采用鲍尔环， 填料区高度为 6.5 m， 填料区底端距反应塔 底部 1 m， 填料区顶端距反应塔顶部 1.5 m。填料区底端以下 0.4 m和 0.2 m处设 冲洗填料的布气装置和布水装置，填料区中间也设冲洗填料的布气装置和布水装 置。 中心筒上部距填料区顶端 0.8 m处设两个回流窗， 外筒上与回流窗等高处设 出水管。 塔顶中心处设导气管， 导气管长度为 5 m。 整个反应塔有效容积约为 5 m3 0
用该维生素 c 厂二沉池出水作为内循环臭氧接触反应塔中试装置的进水， 流 量为 10 m3/h，水力停留时间约为 30min。进水水质具体如下： CODCT为 280mg/L， 色度 300倍。臭氧投加量为 200mg/L时，处理后出水水质如下： CODcr为 160mg/L， 色度 80倍。同样条件下，采用普通臭氧反应塔， 出水水质为： 0)0^为 190mg/L， 色度 120倍。显然， 由于内循环臭氧接触反应塔气水混合效果好、臭氧溶解度高、 反应充分， 处理效果比普通臭氧接触反应塔更好。
此夕卜，测得出水中溶解氧浓度为 l~2mg/L，有利于后续接好氧生物处理工艺（如 MBBR、 曝气生物滤池等）进行进一步脱碳除氮。 运行过程中发现， 由于二沉池 出水经过纤维球过滤后仍有不少悬浮物， 几天后就造成填料堵塞， 导致处理效果 下降， 此时采用气水进行冲洗， 处理效果得到恢复。
实施例 2:
用某维生素 B12厂二沉池出水作为实施例 1 中内循环臭氧接触反应塔中试装 置的进水， 流量为 7 m3/h， 水力停留时间约为 45min。进水水质具体如下： CODCT 为 420mg/L， 色度 700倍。 臭氧投加量为 300mg/L时， 处理后出水水质如下： CODCT为 260mg/L， 色度 150倍。 同样条件下， 采用普通臭氧反应塔， 出水水质 为： 。00„为3101¾ ， 色度 280倍。
