城市污水处理厂多期实施控制系统的实现

Control System of Urban Sewage Treatment Plant Multiphase Implementation

摘要: 根据当前污水处理厂的处理能力分期实施的特点，本文结合某城市5万吨/日污水处理厂一期、二期的工艺特点，分析其控制系统的构成和控制方式以及数据实现，提出了一种基于ControlLogix构建的污水处理厂的控制方案，较好地解决了一期与二期的数据采集、数据通讯和控制等问题，取得较好的效果。

Abstract: Considering the multi-phase processing features in current sewage treatment plants, this paper put forward a control plan upon ControlLogix based on the Phase I and Phase II technological features of a 50,000 t/day urban sewage treatment plant after analyzing the composition of its control system and the data implementation, which solved problems of data acquisition, data communication and control in Phase I and Phase II with favorable results.
