Simulated Wastewater

To solve the problem of huge investment and high difficulty of individually treating landfill leachate, the experiment adopted A2O simulated wastewater treatment plant to treat landfill leachate combined with municipal sewage.Under the conditions of 11h HRT, 1.0-2.0mg/L DO concentration, 200% mixture reflux proportion, 80% sludge reflux proportion and 20d sludge age, adding langdfill leachate to municipal sewage with the proportion of 1:1500, 1:1000 and 1:600, the effluent concentration can achieve the first order A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant. When the proportions come to 1:400 and 1:200,the effluent quality can’t reach the standard. After a comprehensive consideration of water quality and landfill leachate treatment amount in practice, we can draw a conclusion that the 1:600 proportion is the most suitable one of adding landfill leachate to municipal sewage.
