The toxicity of landfill leachate of domestic wastes in different treatment unites landfill leachate pretreatment (No.1), facultative lagoon (No.2), aerated lagoon (No.3), mineralized refuse bioreactor (No.4) and catalysis iron inner electrolysis (No.5) of leachate treatment process in Shanghai was determined based on CellSense biosensor with E. coli. The results showed that the toxicity of the effluent in different treatment unites for landfill leachate increased during the treatment process due to the influence of matrix effect and intermediate toxic products of refractory organic matters. The toxicity of the effluent from No.1 to No.5 unites are 90% (EC10), 80% (EC30), 60% (EC50), 80% (EC50) and 2% (EC50), respectively. This showed no significant correlation with their corresponding COD and ammonia nitrogen concentrations. |
