The effect of shock-loading of zinc, copper and cadmium ions on the removal of total organic carbon (TOC) and phosphate in an anaerobic-aerobic activated sludge process was investigated. TOC removal was not sensitive to shock-loading of Zn(2+) and Cd(2+) ions, and complete removal was achieved even at 20 mg Zn(2+)/l and 20 mg Cd(2+)/l. However, with over 1 mg Cu(2+)/1 TOC removal efficiency decreased. PO inf4 (sup3-) removal, in contrast, was extremely sensitive to these metal ions, with the… CONTINUE READING
