Solution of Automatic Control System Based on PLC in Decentralized Wastewater Treatment

Abstract

KEYWORD:Decentralized wastewater treatment; Programmable logic controller (PLC); Automatic control ABSTRACT: Decentralized wastewater increasingly serious, remote control of small scale wastewater treatment station operation has become urgent technology problems. This paper mainly introduces the component and function of automation system used in decentralized wastewater treatment and how to use PLC to achieve automation control. The control automation, resource optimization, management and control integration were archived. background
