Included activities starts

The activity starts with receiving wastewater at the gate of the treatment facility. Collection and transportation of wastewater to the treatment plant are not included.

Included activities ends

The activity ends with the treatment of wastewater and the specific discharge of waste into the environment. It includes expenditures for wastewater treatment at waste treatment plants and related infrastructure of the facility. Emissions from any sludge digestion, biogas generation, and utilization (noting specific wastewater components) are also included.

Description

This dataset represents the treatment process of leachate generated from landfilling activities. The dataset is applicable to arid and semi-arid regions (long-term average annual precipitation < 400 mm), and the treatment technologies primarily include membrane separation, redox processes, adsorption, ion exchange, and electrodialysis.

Process Description

Landfill leachate, also known as seepage, is a secondary pollution generated during the landfilling process. Leachate forms when pollutants contained in waste are dissolved by moisture due to compaction, microbial activity, fermentation, and other factors during landfilling, mixing with precipitation, runoff, and similar sources to create wastewater. Its water quality varies significantly depending on factors such as waste composition, local climate, hydrogeological conditions, landfill age, and landfilling methods.
