摘要：随着人民生活水平的提高和可持续发展战略的需要，污水处理越来越受到社会的重视。我国是个工业大国，污水处理既可以起到环保作用，又可以实现水的重复利用。

    本设计中摒弃了传统的污水指标监测方法，结合无线传感器网络的监测理论，采用ZigBee技术设计了一套低成本、低功耗、易于维护的污水指标实时监测系统，极大的减少了施工工作量。本文设计的思路是用ZigBee技术建立一个无线传感网络，使得数据可以在此网络中快速实时地进行传输。系统主要由如下几个部分组成：数据采集终端节点，路由节点，协调器节点，监控中心。其中，数据采集终端节点，路由节点，协调器节点组成ZigBee无线传感网络，负责信息的采集与传输，最终将信息发送给监控中心，使得监控人员能及时获得污水信息，做出下一步的处理。94434

该系统用于实现污水指标的实时监测，为污水的达标排放提供参考依据。同时监测结果还能够反映污水处理系统各个组成部分的运行状况，为企业管理人员制定生产经营策略提供依据，有利于提高企业的管理水平，具有很好的经济和社会意义。

Abstract: With the improvement of people's living standards and the need of sustainable development strategy, more and more attention has been paid to sewage treatment 。China is a large industrial country, sewage treatment can not only play a role in environmental protection, but also to achieve the reuse of water。

    This design abandons the traditional monitoring methods of sewage indicators, combined with monitoring theory of wireless sensor network, a low cost, low power consumption, easy maintenance of sewage indicators real-time monitoring system design using ZigBee technology, greatly reducing the workload of construction。 The idea of this paper is to use ZigBee technology to build a wireless sensor network, so that the data can be transmitted in this network in real time。 The system is mainly composed of the following parts: data acquisition terminal node, routing node, coordinator node, monitoring center。 Among them, the data acquisition terminal node, routing node, the coordinator node of ZigBee wireless sensor network, responsible for the collection and transmission of information, information will eventually be sent to the monitoring center, the monitoring personnel can timely access to sewage information, make the next step of the process。

    The system can be used to realize the real-time monitoring of sewage indicators and provide reference for the discharge of sewage。 At the same time, the monitoring results can reflect the operation status of the sewage treatment system composed of various parts of the development of production and operation strategy to provide the basis for enterprise management, improve enterprise management level, and has good economic and social significance。
