Municipal Landfill Leachate Real-time Processing Measurement and Control Method

Abstract

Landfill leachate is one of the main sources of stench in refuse transfer stations, and it is also one of the main pollution sources in municipal waste water pipe network. This paper designs an automatic treatment and process control system for landfill leachate based on plasma to realize real-time monitoring and automatic control of multiple parameters in the process of landfill leachate treatment. The whole system is divided into two parts: on-site control and remote control. remote control: single-chip microcomputer collects signals of each sensor, communicates with wifi module through serial port, and PC logs into internet of things cloud platform to realize real-time monitoring. The single-chip microcomputer remotely controls the external execution module through the wifi module. Field control: taking the data detected by turbidity and dissolved oxygen sensors as input of fuzzy control, establishing a correct fuzzy rule base and obtaining a fuzzy output set; IO port communication is carried out between PLC and single-chip microcomputer to read the result of fuzzy control operation of single-chip microcomputer and intelligently control the external executing mechanism. Finally realize the function of man-machine interaction.
