AI Technical Summary

Technical Problem

Existing technologies for treating leachate from municipal solid waste and landfills suffer from methane emissions and high energy consumption, and insufficient carbon sources during co-processing lead to additional costs.

Method used

An integrated landfill leachate treatment system is adopted, including a landfill leachate treatment structure, a municipal solid waste leachate treatment structure, an anaerobic digester, a primary denitrification tank, a cooling structure, a primary nitrification tank, a secondary denitrification tank, a secondary nitrification tank, ultrafiltration components, nanofiltration components, and reverse osmosis components. Through denitrification and nitrification treatment, the municipal solid waste leachate is used as an endogenous carbon source, eliminating the need for external carbon sources and reducing methane emissions and energy consumption.

Benefits of technology

It achieves the goal of meeting the latest water quality standards while reducing methane emissions and energy consumption, lowering treatment costs, and optimizing denitrification efficiency by replacing external carbon sources with internal carbon sources.
