【 摘 要 】

The impacts of five types of typical specific pollutants like herbicides (including prometon, propazine, acetochlor, metolachlor and bentazone) upon microbial activity of activated sludge systems in wastewater treatment plants were studied by quantitatively feeding specific pollutants into these systems and measuring changes to specific oxygen uptake rate (SOUR) of the systems. The research results suggest that all these five types of specific pollutants significantly inhibit microbial and aerobic metabolisms of the activated sludge systems. The impacts of these herbicides are arranged as follows according to their degrees: bentazone
