Description:
The project investigated the discharge of landfill leachate into a municipal waste water collection system with subsequent treatment at the municipal treatment plant. The research article points out that leachates from disposal sites can be mixed with municipal wastewater and treated by wastewater treatment plants using secondary aerobic treatment. Leachates are effluents, high in organic content and in many instances similar to industrial effluents. In order for a wastewater treatment plant to accept this type of effluent, the following conditions must be met. First, air supply and oxygen transfer capacity must be sufficient to maintain aerobic conditions within the aeration basin with the increase in organic loads. Second, sufficient nutrient concentrations (especially phosphorus) must be observed in order to maintain necessary operating conditions.
