| Abstract: | By simulated tests of activated sludge process with toxicant cadmium (Cd) in the laboratory, the results showed that to a certain concentration of Cd, biological treatment of waste water was gradually depressed as its concentrations increased. Cd residue in effluent incereased as its concentretion in influent gor high, and decreased as sustained time of sludge increased. Cd concentration in mixed liquid hadnot a tangible impact on sludge in second sedimentation tank. Based on the results, the author offered a proposal for reviewing the discharge standard of maximum permissible concentration of Cd in Shanghai sewerage system. |
