NINGLING · LANDFILL LEACHATE TREATMENT
Ningling Landfill Leachate Treatment Project
TREATMENT CAPACITY
150 t/d
Project Overview
A landfill-leachate treatment project serving a county-level municipal solid-waste landfill in Shangqiu. The leachate is a complex, high-concentration organic wastewater with high pollutant loading, large fluctuations in water quality and flow, high ammonia nitrogen, imbalanced nutrient ratios, heavy metals and toxic substances. Its water-quality characteristics also change significantly as the landfill ages.
TREATMENT / DISCHARGE REQUIREMENT
150 t/d treatment capacity · Effluent after treatment meets Table 2 of GB16889-2024.
Landfill Leachate Characteristics
- Complex, high-concentration organic wastewater
- High pollutant concentration and large fluctuations in water quality and flow
- High ammonia-nitrogen concentration
- Imbalanced nutrient ratios
- Presence of heavy metals and toxic substances
- Water-quality characteristics change significantly with landfill age
Treatment Targets
- Treat 150 t/d of landfill leachate
- Meet Table 2 requirements of the Standard for Pollution Control on the Landfill Site of Municipal Solid Waste (GB16889-2024) after treatment
Engineering Focus
- Designed for highly concentrated and highly variable landfill leachate
- Treatment target is tied to the current GB16889-2024 Table 2 discharge requirement
- Project conditions account for leachate characteristics that change with landfill age
Compliance Standard
- Standard for Pollution Control on the Landfill Site of Municipal Solid Waste (GB16889-2024), Table 2.
