Description

污水处理设备的控制系统、方法、电子设备及计算机可读存储介质
本申请要求于2018年03月23日提交中国专利局的申请号为CN201810250472.0、名称为“污水处理设备的控制系统及方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及水处理技术领域，尤其是涉及污水处理设备的控制系统、方法、电子设备及计算机可读存储介质。
背景技术
目前在污水处理领域，大型的城镇污水处理厂以及工厂的生产污水处理，由于其处理规模较大，进水较为规律，且前端一般均有调节池，保证进入处理系统的水量以及水质尽可能均匀，所以在设计参数以及实际运行阶段均是按照较为理想的稳定的状态来考虑的，在实际整个污水处理站运行时，整个系统均可以稳定运行，对于系统使用的各种耗电功能设备可统一控制，还可根据在线检测仪表反馈来对各种改变进行调整，保证污水处理过程的正常进行。对于采用生物处理工艺的亦可维持微生物稳定的生长环境，从而保证系统的处理效果。所以，对于大型污水处理站来说，除了一些特殊的突发情况，整个系统可以保持良好的稳定状态。与之相对的，目前在我国，小型污水处理设备由于其施工量小、安装周期短、运输方便等优点，对于小型的农村城镇开始逐步采用小型的分散式污水处理设备，满足整个农村城镇的污水处理要求，与传统的建立城市管网收集整个城市的污水到大型污水处理厂相比，减少了管网建设的不便以及成本投入，但是，小型污水处理设备处理能力一般适用于几户到几十户合用，不设调节池以保证小型污水设备占地小，施工简单的优势。因此，小型污水设备无论是用于处理生活污水(较多)还是小型生产企业废水(较少)，进水水量以及水质往往不均匀，无法避免用水量日变化给系统带来直接影响，对系统冲击较大，直接影响处理过程和效果，对于采用生物处理方法的小型设备来说，对微生物的生长影响较大，即使按照传统的根据日常规律设置时间段运行设备也存在较大不足。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
目前，小型污水处理设备与传统的建立城市管网收集整个城市的污水到大型污水处理厂相比，减少了管网建设的不便以及成本投入，但是，小型污水处理设备处理能力一般适用于几户到几十户合用，不设调节池以保证小型污水设备占地小，施工简单的优势。因此，小型污水设备无论是用于处理生活污水还是小型生产企业废水，进水水量以及水质往往不均匀，无法避免用水量日变化给系统带来直接影响，对系统冲击较大，直接影响处理过程和效果，对于采用生物处理方法的小型设备来说，对微生物的生长影响较大，即使按照传统的根据日常规律设置时间段运行设备也存在较大不足。
基于此，本申请实施例提供的污水处理设备的控制系统及方法，可以克服现有小型污水处理设备模式化、抗变化冲击能力差的问题，提高控制系统的稳定性，并且达到节约能源的效果。
为便于对本实施例进行理解，首先对本申请实施例所公开的进行详细介绍。
实施例一：
图1为本申请实施例一提供的一种污水处理设备的控制系统示意图。
参照图1和图2，污水处理设备的控制系统包括：单片机20、与单片机20分别相连的提升泵10和气泵30，还包括用户端设备50和污水处理设备40。这里的污水处理设备40为小型污水处理设备。
用户端设备50与提升泵10相连，通过管网将用户排水进行汇总并自流至提升泵10所在的池体内。用户端设备50的处理水量范围为0.5-200m 3/d。用户端设备50为几户到几十户的排水简单汇总收集至一个排出口并自流至提升泵10所在小池内，管网简单，距离较短，保证处理量在较小范围内。
在本申请的一种可选实施例中，提升泵10上设置有浮球，浮球根据池体内的水位高度控制提升泵10的开关，进而触发第一开关信号。参照图3，提升泵10自带有浮球，并置于一个容积较小且占地面积小的池体内，当用户端设备50的排水口高度低于池内水面或压 力不足以自流进入小型的污水处理设备40的进水口时，浮球根据水的浮力随水位高度上升进而控制提升泵10自动打开开关，将污水抽至污水处理设备40，但该提升泵10并不是直接接电或PLC(Programmable Logic Controller，可编程逻辑控制器)的，而是连接到单片机20上，由单片机20接收其第一开关信号并供电。
提升泵10触发第一开关信号后，单片机20获取并根据第一开关信号对气泵30的运行模式进行调控，生成第二开关控制信号，气泵30根据第二开关信号进行曝气控制和回流控制。
单片机20通过判断提升泵10的运行状态来对气泵30的运行状态进行调控。第一开关信号分为开启信号和关闭信号，对应的第二开关控制信号包括延时启动信号和延时停止信号。单片机20根据开启信号对气泵30开启运行的延迟时间进行调控，生成延时启动信号；或者，单片机20根据关闭信号对气泵30停止运行的延迟时间进行调控，生成延时停止信号。
浮球可以通过柔性的线缆连接安装于提升泵上的机械开关，当水面上升时，浮球随着水面上升，当水面上升至预设高度及以上时，与浮球连接的线缆绷紧并拉动机械开关，机械开关处于ON状态并发出开启信号，该第一开关信号可发送给单片机20。而当液面高度低于预设高度时发出关闭信号。
在本申请的另一种可选实施例中，采用电子式液位开关替代浮球，通过内置电子探头对水位进行检测，再由芯片对检测到的信号进行处理，当判断到水达到预设高度时，芯片输出高电平例如24V或5V等(PNP型或NPN型均可)，当判断到水位低于预设高度时，芯片输出低电平例如0V。高低电平的信号通过单片机来读取(高电平相当于开启信号，低电平相当于关闭信号)，当单片机读取到高电平时驱动提升泵工作，当单片机读取到低电平时，单片机不驱动提升泵工作。
具体的，单片机20在判断提升泵10一直处于运行状态的情况下，将控制气泵30也保持运行状态；单片机20在根据关闭信号判断提升泵10停止运行的情况下，将调控气泵30延迟一定时间(比如半小时)后自动停止运行，即向气泵30发出延时停止信号；单片机20在根据开启信号判断提升泵10开始运行的情况下，将调控气泵30延迟一定时间(比如十分钟)后自动开启，即向气泵30发出延时启动信号。通过单片机20根据提升泵10的运行状态来调控气泵30的运行，控制曝气或回流的量、间隔以及延迟时长，从而可以保证在小型污水处理设备中没有进水、营养不足时，好氧区仍曝气造成好养微生物内源消耗的弊端，可维持生物在较好的状态，同时也可以达到减少气泵30的无效运行时长，节约电能的效果。通过将提升泵10的启停与气泵30的启停相结合，大大增强了小型污水处理设备对 来水变化冲击的应对能力，保证了系统的有效性。另外，上述实施例选用单片机20作为控制主体，更适合于小型污水处理设备的特性，减少了笨重性，整体布局更紧凑灵活。
气泵30通过两根气管分别连接到污水处理设备40中的曝气区和气提区，并根据第二开关信号调节气管上的阀门进行曝气控制和回流控制，给系统提供好氧曝气以及气提回流泥水。具体的，气泵30置于小型污水处理设备之外，使用寿命更长，并通过气管与小型污水处理设备相连，气管上设有小阀门，通过调节阀门使曝气量和回流量合理稳定。
阀门可以是电控阀门，阀门与单片机数量连接，单片机可以控制阀门打开的大小，或者控制处于打开状态的阀门的数量，来控制曝气量和回流量。
污水处理设备40为小型污水处理设备，整体体积较小，结构布局紧凑。小型污水处理设备的污水处理规模与用户端设备50的规模相匹配，多采用生物处理方法进行污水处理，生物处理方法包括AO(Anoxic-Oxic，缺氧-好氧)工艺和A2O(Anaerobic-Anoxic-Oxic，厌氧-缺氧-好氧)工艺，满足出水达标要求，该设备中含有曝气区和气提区，通过气泵30提供好氧曝气以及气提回流泥水处理措施。
上述实施例所提供的污水处理设备的控制系统，是针对小型污水处理设备，通过单片机将提升泵的启停与气泵的启停相结合，合理控制了曝气和回流，维持系统内微生物生产的稳定性，从而大大增强了小型污水处理设备对来水变化冲击的应对能力，保证了系统的有效性；并且，大大缩短了气泵无效运行时间，控制方法更为灵活，更具针对性，也达到了节省电能的目的；另外，选用单片机作为控制主体，较传统的PLC控制更适合于小型污水处理设备的特性，减少了笨重性，整体布局更紧凑灵活。
实施例二：
图4为本申请实施例二提供的污水处理设备的控制方法流程图。

步骤S110，提升泵根据水位高度触发第一开关信号，第一开关信号包括开启信号和关闭信号；

步骤S122，单片机根据关闭信号对气泵停止运行的延迟时间进行调控，生成延时停止信号；
步骤S130，气泵根据延时启动信号和延时停止信号进行曝气控制和回流控制。
进一步地，检测到水位高度高于预设高度时，触发开启信号；检测到水位低于预设高度时，触发关闭信号。
进一步地，单片机接收到开启信号后，经过第一预设时间间隔后发出启动信号。
进一步地，单片机接收到关闭信号后，经过第二预设时间间隔后发出关闭信号。
