What are landfill operations?
Operation of Landfills. The landfill operation is actually a biological method of waste treatment. The liquid produced during decomposition, as well as water that seeps through the groundcover and works its way out of the refuse, is known as leachate.
What is the basic structure of a landfill?
There are four critical elements in a secure landfill: a bottom liner, a leachate collection system, a cover, and the natural hydrogeologic setting. The natural setting can be selected to minimize the possibility of wastes escaping to groundwater beneath a landfill. The three other elements must be engineered.
How do you manage landfill leachate?
Leachate can be controlled in lined landfills with leachate collection and storage systems. These systems typically include provisions for the drainage of leachate within the landfill and pumping the leachate to storage tanks. The stored leachate can then be trucked or pumped to a wastewater treatment plant.
What are the 4 processes in waste removal?
Waste disposal methods
- Recycling. Incineration.
- Other thermal treatment plants. Chemical-physical and biological treatment.
- Chemical-physical and biological treatment. Landfills.
- Landfills. Collection and logistics.
How many phases does landfill process have?
Generally, it is accepted that landfills undergo at least four phases of decomposition, (1) an initial aerobic phase, (2) an anaerobic acid phase, (3) an initial methanogenic phase, and (4) a stable methanogenic phase (Christensen and Kjeldsen, 1995).
What is in landfill leachate?
Generally leachate has a high biochemical oxygen demand (BOD) and high concentrations of organic carbon, nitrogen, chloride, iron, manganese, and phenols. Many other chemicals may be present, including pesticides, solvents, and heavy metals. The direction of groundwater flow.
