Question

本文介绍了城市污水处理环节中SBR曝气反应池的基本工艺和流程，并通过研究设计一套基于PLC控制的SBR曝气反应池污水处理系统。根据SBR曝气反应池污水处理的要求设计设备的电器控制与自动控制线路，主要包括设备的启停、状态信号故障信号、和信号采集等，最后按照工艺要求设计PLC控制系统，其中包括PLC的选型、系统资源配置以及按照污水处理工艺编制PLC程序。其硬件部分主要包括了鼓风机电路、压力传感器以及溶解氧分析仪等部分，软件部分以开机、启停、手动、自动为主程序，主程序主要是以数字量以及开关量为主。以压力检测软件控制部分、溶解氧分析仪检测部分以及调节阀控制部分为子程序，它主要以模拟量为主。通过软件部分主程序和子程序的配合，从而达到设计所需的要求。
关键词：SBR曝气反应池，工艺流程，模拟量

Answer 1

In municipal wastewater treatment are introduced in this link aeration reaction pool, the basic process and SBR process, and through the study design a set of based on PLC control of SBR aeration reaction pool sewage treatment system. According to the requirement of the SBR reaction pool aeration sewage treatment equipment of electric control and automatic control circuit design, including equipment start-stop, state signal fault signal, and the signal acquisition and so on, according to requirement of process design of PLC control system, finally, including PLC selection, system resource allocation and PLC program according to the sewage treatment process. Its hardware part mainly includes the blower circuit, pressure sensors and dissolved oxygen analyzer part, software part mainly boot, start-stop, manual and automatic program, is the main digital quantity and switch on the main program. In order to pressure
