本实施方式中，所述预设照射剂量为15mJ/cm 2，在该照射剂量下，对微生物的灭活效果较佳，且相应的能耗不高。
可以理解的是，对注水设备及相应的管路造成腐蚀等影响的微生物主要为腐生菌、铁细菌及硫酸盐还原菌，因此，现以10 5-10 6cfu/mL(每毫升样品中含有的细菌群落总数)浓度的腐生菌、铁细菌、硫酸盐还原菌水样为例说明本发明的原理及优势。使用波长255、280、350纳米的紫外LED对细菌负荷为10 5-10 6cfu/mL的水样进行消毒，水样接受的平均辐射强度为51uW/cm 2。
图2、图3以及图4分别给出了紫外LED消毒装置对腐生菌、铁细菌以及硫酸盐还原菌的灭活速率图；而图5给出了三种不同波长紫外LED灯的单位对数灭活率能耗对比图。图2、图3以及图4中分别给出了使用255纳米紫外LED灯、280纳米紫外LED灯和350纳米紫外LED灯作为照射光源的测试结果，并进行了对比。可见，虽然15mJ/cm 2的255纳米紫外线照射剂量绝大多数情况下比280纳米紫外LED灯具有更优异的灭菌性能，但255纳米紫外LED灯造价高，功率转换效率低，280纳米紫外LED灯的单位对数灭活率能耗显著低于255纳米，从而最大程度平衡了经济性与高效性。此外，280纳米紫外LED灯照射后微生物的复活程度明显减弱，改善了紫外消毒后生物易复活的缺陷。
可以理解的是，水中颗粒物浓度是影响紫外光消毒效果的最主要因素。在细菌负荷为10 5-10 6cfu/mL的腐生菌水样中，添加不同浓度的颗粒物，采用280纳米紫外LED对水样进行消毒，图6给出了颗粒物浓度影响下波长280纳米的紫外LED灯灭活腐生菌的灭活速率图。由图6可知，给出了几种颗粒物固定值取值情况下的测试结果，并与未添加颗粒物的灭活速率图进行了对比。可见，本发明受低浓度颗粒物的影响较小，30mg/L以下浓度的颗粒物对280纳米紫外LED灯灭活率的影响在10％之内。
综合图2至图6可知，利用280纳米的紫外光对微生物进行照射，可最 大程度平衡了经济性与高效性，即可实现相对较佳的灭活率，同时成本不高，运营维护成本低，且可易于大规模推广应用。
参见图7，是本发明一实施方式的注水处理装置的结构示意图，所述注水处理装置1可应用于注水处理系统。如图7所示，注水处理装置1包括注水输入口11、光照处理腔室12及注水输出口13，注水输入口11用于与注水管路(图未示)连通，以使注水流入所述光照处理腔室12中；注水输出口13用于与在所述注水处理装置1下游的注水管路(图未示)连接，以供被处理后的注水流出所述光照处理腔室12。
本实施方式中，所述注水处理装置1可采用前述的注水处理方法对注水进行处理。
在所述光照处理腔室12中设有紫外灯14，且所述紫外灯14设于注水输入口11与注水输出口13之间，所述紫外灯14发出的紫外光波长为280纳米，以利用该波长的紫外光对注水进行照射处理，实现较佳的微生物灭活效果，同时对生态环境的友好度较好，且维护成本较低，可大规模推广应用。
可以理解的是，紫外灯可根据自身材料的差异发射出不同波长的紫外光，本实施方式中，可选用紫外LED灯作为紫外灯。由于波长范围为255纳米至265纳米的深紫外光与DNA吸收峰重合度较高，此时紫外灯对微生物的灭活效果最佳，然而由于制造技术及自身材料限制，波长越短的紫外LED灯造价越高、寿命越短且功率转换效率越低；而UVB/UVA范围的长波紫外灯虽然经济性较高，但对微生物的灭活效果较差。综合考虑工程应用的经济性与高效性，本发明选用280纳米的紫外LED灯作为消毒装置的光源。
参见图8，是本发明第一具体实施方式的注水处理装置的结构示意图。本具体实施方式中，注水处理装置2包括注水输入口21、光照处理腔室22及注水输出口23，而设于光照处理腔室22中的紫外灯24为紫外LED灯，且紫外LED灯所述发出的紫外光波长为280纳米。
本具体实施方式中，所述紫外LED灯包括一个面光源阵列板，所述面光 源阵列板具有用于引导注水流向所述注水输出口的板面，且所述板面为紫外光出射面。波长为280纳米的紫外光自所述面光源阵列板的板面出射时，可对流经板面的注水水流进行均匀照射，由于紫外LED灯为面光源，因而在照射面积增大后，对注水中的微生物的照射效率提高，从而提升对微生物的灭活效率。
可以理解的是，所述紫外LED可包括至少一个面光源阵列板，而在所述面光源阵列板的数量大于一时，各个面光源阵列板可相互平行设置。
可以理解的是，在所述面光源阵列板的板面上设有多个紫外LED灯珠，以在通电后形成面光源。
可以理解的是，所述面光源阵列板两侧的板面均可用于出射紫外光，也即所述面光源阵列板两侧的板面均能够实现前述板面的功能。
参见图9，是本发明第二具体实施方式的注水处理装置的结构示意图。本具体实施方式中，注水处理装置3具体包括注水输入口31、光照处理腔室32及注水输出口33。
本具体实施方式中，设于所述光照处理腔室32中的紫外灯24为紫外LED灯，且紫外LED灯所述发出的紫外光波长为280纳米。与第一具体实施方式不同之处在于：
本具体实施方式的紫外LED灯包括中间层面光源阵列板341及设于所述中间层面光源阵列板341两侧的侧边层面光源阵列板342，所述中间层面光源阵列板341设于所述光照处理腔室32的中部位置处，所述侧边层面光源阵列板342在靠近所述注水输入口31一侧的板体上设有用于引导注水沿所述侧边层面光源阵列板远离所述中间层面光源阵列板341一侧的板面流动的导流部343。
三层面光源阵列板的设置，可增大紫外光照射注水的面积，提升对微生物的灭活效率。与此同时，设置的导流部343结构可利于将注水水流引导至相应的板面上进行紫外光光照，且加强位于远离所述中间层面光源阵列板341 的所述侧边层面光源阵列板342一侧的注水的流动性。
本具体实施方式中，所述导流部343沿靠近所述注水输入口31及所述中间层面光源阵列板341倾斜设置。
可以理解的是，可视具体情况增加所述侧边面光源阵列板的个数，以达到相应的对微生物的灭活效率。
参见图10，是本发明第二具体实施方式中的紫外LED灯及注水流向示意图。注水自注水输入口(图未示出)流入光照处理腔室(图未示出)后，在导流部343对注水进行导流，从而形成四股注水分别沿上侧的侧边层面光源阵列板342的上板面及下板面、下侧的侧边层面光源阵列板342的上板面及下板面流向注水输出口(图未示出)。
本具体实施方式中，上侧的侧边层面光源阵列板与下侧的侧边层面光源阵列板相对中间层面光源阵列板341互为镜像对称结构。
参见图11，是本发明一实施方式的注水处理系统4的结构示意图。本实施方式提供的注水处理系统4，包括注水管路41及注水处理装置42，所述注水处理装置42可以采用如上所述的注水处理装置1、注水处理装置2以及注水处理装置3中的任意一种结构。所述注水处理装置42设于所述注水管路41上。
本实施方式中，所述注水处理装置42设于所述注水管路41的注水端位置处。在注水处理系统4运作时，注水管路41的注水端输入注水，在注水途经所述注水处理装置42时，利用所述注水处理装置42中的、紫外光波长为280纳米的紫外灯照射途经的注水，实现杀菌消毒。
可以理解的是，所述注水处理系统4可为海下注水处理系统、船舶压载水处理系统以及生活生产水处理注水处理系统等。所述海下注水处理系统应用于石油开采领域，即通过所述海下注水处理系统将符合质量要求的水注入油层中，以保持或提高油层压力，从而实现更高的石油采收率。所述船舶压载水处理系统应用于船舶运输领域，即通过所述船舶压载水处理系统将符合 质量要求的水注入船上，以保持船舶的稳定。所述生活生产水处理注水处理系统应用于水处理领域，即通过所述生活生产水处理注水处理系统将水注入到特定的容器中，以实现水的净化。
