Description
本发明涉及一种雨水净化设备，具体涉及一种一体化雨水处理装置。
随着城市化进程的加快，地面上不透水面积显著增加，污染物在这些不透水的地面上逐渐累积，待降雨时，雨水冲刷地面将污染物冲入雨水径流系统形成雨水径流污染。雨水径流污染是一种扩散性污染，污染物进入到自然水体，造成水体污染，所述污染物包括颗粒物、有机物、重金属等有毒有害物质。因此，城市化进程和工业化发展导致水源危机和雨洪危害日益严重。
随着水源危机和雨洪危害的加剧，将雨水加以收集利用作为水资源进行综合治理已成为重要的新兴课题。在城市总体规划上，过去采用的合流制排水系统大多数已被改制，改为分流制或截流制排水系统。随着城市大气污染及地面污染的严重，雨水径流污染愈加严重，尤其是污染物较多的初期雨水，某些地区的初期雨水的污染物指标最高值已远远高于典型城市生活污水。因此，有必要对雨水，尤其是初期雨水进行处理。
目前我国对初期雨水的收集处理还处于初级阶段，收集初期雨水仅仅是不让其排入水体污染水质，而对于初期雨水的净化处理和回用则很少考虑，多数直接排入市政生活污水管网。初期雨水中含有的污染物浓度较高，尤其是道路初期雨水，直接排入生活污水管网会给污水厂带来较大的负荷。
发明内容
为了解决上述问题，本发明提供一种一体化雨水处理装置，所述装置包括 井体和位于井体上方的盖板，所述井体底部自下而上设置溢流墙，井体内部被所述溢流墙分隔为沉降区和过滤-渗透区；
所述沉降区上方的盖板上设置有进水口；
所述过滤-渗透区的底部铺有过滤渗透介质；
所述过滤-渗透区的井体侧壁上部设置有溢流管；
在沉降区和过滤-渗透区之间，设有贯穿溢流墙的穿孔排水管，穿孔排水管穿过溢流墙并伸入过滤渗透介质中。
进一步地，在所述沉降区内，靠近溢流墙的盖板上还设置向下延伸的挡板，所述挡板的最底端不高于溢流墙的顶端，还进一步地，所述挡板延伸至溢流墙顶端下方。
进一步地，在所述进水口设置格栅板；进一步地，在所述格栅板下方还设置过滤装置。
进一步地，所述过滤装置为滤水桶或滤水袋。
进一步地，所述滤水桶或滤水袋为网状结构。
进一步地，所述滤水桶上靠近格栅板处还设置溢流口。
进一步地，所述滤水桶或滤水袋位于所述挡板的左侧。
进一步地，所述过滤渗透介质为从下到上依次铺设的透水土工布、多孔介质层和生物介质层。优选在生物介质上种有植物。优选植物是树。因此优选在所述过滤-渗透区上方的盖板上设置有可拆卸的树池盖板。
进一步地，所述树池盖板根据种在生物介质层中植物的大小进行设置。
进一步地，所述溢流管设置在井体侧壁顶部，即盖板下。
进一步地，所述溢流管管底高于所述溢流墙的顶端。
进一步地，所述生物介质层顶部靠近溢流墙的一侧设有防冲乱石。
进一步地，所述生物介质选自落叶堆肥、浮石、泥炭土、珍珠岩、沸石、陶粒、生物活性炭或沙子中的一种或多种。
进一步地，所述多孔介质层选自砾石层、碎石层或其混合层。
更进一步地，可根据雨水的处理需要设置生物介质层和多孔介质层的种类或厚度。
进一步地，所述穿孔排水管为“L”型，竖直段在沉降区、水平段在过滤渗透介质中，优选所述水平段在生物介质中；还优选在生物介质中的部分呈网状分布。
在本发明的雨水处理装置中，所述滤水桶或滤水袋为网状结构，可以拦截初期雨水中比较大的垃圾、树叶等污染物；
所述滤水桶上还设置溢流口，当滤水桶拦截的污染物过多，可以使滤水孔滤水速度较慢且水位达到溢流口时，滤水桶中的雨水可直接经溢流口流出，进入沉降区；
挡板的最下方低于溢流墙的墙顶，漂浮物、油和油脂则会被挡板拦截在沉降区，雨水从挡板下方流动，可以保证漂浮物、油和油脂不会进入过滤及渗透区；
沉降区内的雨水通过穿孔排水管进入生物介质层中经处理后渗透到地下，保证滤水桶收集的污染物不会浸泡在水中，同时沉降在井底的颗粒物不会堵塞穿孔排水管；
所述穿孔排水管在生物介质中的部分呈网状分布，可以保证生物介质层充分过滤雨水；
植物种在生物介质层中，可以吸收雨水中的氮、磷等物质；植物根系可以对重金属等污染物进行拦截和吸附，同时植物根系周围的微生物也可以对有机污染物进行降解。
本发明还提供一种道路雨水处理系统，所述系统包括市政道路上的雨水干管，与雨水干管连接的一条或多条雨水支管，在雨水支管末端连接的一个或多个雨水口，其特征在于，在所述雨水口或其附近设置如上所述一体化雨水处理装置。
当一体化雨水处理装置设置在所述雨水口附近时，其可以与一个或多个雨 水口连通，例如与1-10个，2-5个或2-3个雨水口连通。
进一步地，所述一体化雨水处理装置根据每个雨水口的雨量情况设计成不同的大小和规格。

下文将结合具体实施例对技术方案做更进一步的详细说明。应当理解，下列实施例仅为示例性地说明和解释本发明，而不应被解释为对本发明保护范围 的限制。凡基于本发明上述内容所实现的技术均涵盖在本发明旨在保护的范围内。
实施例1
本实施例中一体化雨水处理装置的结构如图1所示，其中所述装置包括井体1和位于井体上方的盖板2。所述井体内部被溢流墙3分隔为沉降区A和过滤-渗透区B，所述溢流墙3自井体底部自下而上设置，并在靠近井体顶部的盖板2位置终止，使得沉降区A和过滤-渗透区B之间留有连通口。在所述沉降区A内靠近该连通口的盖板2上还设置向下延伸的挡板6。所述挡板6的最底端低于溢流墙3的墙顶。所述沉降区A上方的盖板2上设置有进水口，进水口上设置有格栅板4，携带有颗粒物、悬浮物、漂浮物、氮、磷、油和油脂等污染物的初期雨水经格栅板4进入沉降区A。滤水桶5设置在所述格栅板4下方。所述滤水桶5为网状结构，用于拦截从格栅板4流入的初期雨水中较大垃圾、树叶等污染物。
所述过滤-渗透区B的底部从下到上依次铺有透水土工布7、碎石层8和生物介质层9。所述生物介质上种有植物10。
所述过滤-渗透区B上方的盖板2上设置有可拆卸的树池盖板11。
所述过滤-渗透区B的井体1侧壁上靠近盖板2处还设置有溢流管12，所述溢流管12的管底与溢流墙3的顶端齐平。
在沉降区A和过滤-渗透区B之间，设有贯穿溢流墙3的“L”型穿孔排水管13，穿孔排水管13穿过溢流墙3并伸入生物介质中，所述穿孔排水管13在生物介质中的部分呈网状分布，保证生物介质充分过滤雨水。
进一步地，所述滤水桶5上靠近格栅板4处还设置溢流口14。当滤水桶拦截的污染物过多，使滤水孔滤水速度较慢且水位达到溢流口14时，滤水桶5中的雨水可直接经溢流口14流出，进入沉降区A。
进一步地，所述生物介质层9顶部靠近溢流墙3的一侧设有防冲乱石16。所述防冲乱石16可用于降低从溢流墙3流过来的雨水的流速，避免雨水对生物介质 层9进行冲蚀。
进一步地，生物介质选自落叶堆肥、浮石、泥炭土、珍珠岩、沸石、陶粒、生物活性炭或沙子中的一种或多种。
本实施例中的井体1和盖板2可预制，整套设备可在工厂安装好并进行试验，减少现场安装的时间，安装效率高。
实施例2
一种利用实施例1中一体化雨水处理装置对雨水进行处理的方法为：
降雨时，携带有颗粒物、悬浮物、漂浮物、氮、磷、油和油脂等污染物的初期雨水经格栅板4进入井体，滤水桶5可以拦截初期雨水中比较大的垃圾、树叶等污染物。
在重力作用下，一些大的颗粒物则会沉降在井体的沉降区A。随着沉降区A内水位的上升，少量雨水通过穿孔排水管13进入生物介质层9中，经生物介质层9处理后，进入碎石层8，再通过透水土工布7直接渗透到地下。
随着降雨量的增加，当水位上升到溢流墙3顶部的位置时，雨水则会从溢流墙3上方的连通口溢流进入过滤-渗透区B，经生物介质层9处理后渗透到地下。挡板6的最下方低于溢流墙3的墙顶，漂浮物、油和油脂则会被挡板6拦截在沉降区A，雨水从挡板6下方流动，保证漂浮物、油和油脂不会进入过滤-渗透区B。
当降雨量大于生物介质层9的最大处理能力时，过滤-渗透区B的水位会继续上升，当水位上升到溢流管12的管底时，雨水直接溢流排走，保证系统的正常运行。当降雨结束，沉降区A的大部分雨水会继续通过穿孔排水管13进入生物介质层9中经处理后渗透到地下，保证滤水桶5收集的污染物不会浸泡在水中，同时沉降在井底的颗粒物不会堵塞穿孔排水管。
植物10种在生物介质层9中，可以吸收雨水中的氮、磷等物质。植物根系可以对重金属等污染物进行拦截和吸附，同时植物根系周围的微生物也可以对有机污染物进行降解。
实施例3
本实施例中一种道路雨水处理系统的结构如图2所示，所述系统包括在市政道路R之间平行设置的雨水干管C，在雨水干管C两侧上设置多条向市政道路R延伸的雨水支管D，雨水支管C末端为雨水口17，在所述雨水口17设置实施例1中的一体化雨水处理装置18。
进一步地，所述一体化雨水处理装置18根据每个雨水口17的雨量情况设计成不同的大小和规格。
以上，对本发明的实施方式进行了说明。但是，本发明不限定于上述实施方式。凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
