Ruijin Leachate Treatment Plant Project
1 Project Overview
The Ruijin Leachate Treatment Plant Project is a key environmental infrastructure project in Jiangxi Province, China, focusing on the safe treatment of landfill leachate generated from municipal solid waste disposal facilities.
The project addresses high-strength, complex, and highly variable leachate characteristics through a multi-stage advanced treatment system, ensuring stable compliance with strict environmental discharge standards and supporting regional ecological protection.
The treated effluent is either discharged in compliance with regulatory standards or further reused depending on operational conditions, contributing to sustainable waste management.
