Endogenous respiration rate constant (k') reflects the activity of activated sludge. The activity of activated sludge will be decreased after poisoning effect of landfill leachate, the k' will also change. Therefore, k' can reflect the toxicity of landfill leachate to activated sludge. Measured the k' values of activated sludge after poisoning effect of two landfill leachates at 7 concentrations, to verify the correlation between k' values and concentrations of landfill leachate. The results show that, k' and the concentration of landfill leachate showed a strong linear correlation, R2 are 0.930 and 0.956 respectively. Thus, using k' characterized the toxicity of landfill leachate to activated sludge is scientific and rational.

Exploratory study of landfill leachate toxic effects to sludge characterized by endogenous respiration rate constant
