| Abstract: | Pharmaceutical wastewaters contain high content of organic pollutants, most of which are refractory, and some of which are inhibitory to the activity of activated sludge respiration or toxic to bio-organisms. Using wastewater from seven processing units (denoted as W1-W7) in a vitamin synthesis manufacturer as the study object, a flask test was carried out to determine the biodegradability of wastewater, a Warburg respirometer was used to determine the inhibition to the sludge respiration activity induced by wastewater, and a luminescent bacteria test was carried out to determine the acute biotoxicity of wastewater before and after aerobic biological treatment. Results revealed that the biodegradability and biotoxicity of wastewater from seven processing units greatly differed among each other. The ratio of non-biodegradable organic carbon to total organic carbon (TOC) varied from over 90% (W5 and W6) to below 10% (W4 and W7). Median effect concentration (EC50) to the luminescent bacteria differed 500 times between wastewater from W4 (maximum value) and W3 (minimum value). Aerobic biological treatment was effective to remove both TOC and biotoxicity in wastewater from three units (W2, W4 and W7), only effective to reduce toxicity but not TOC at one unit (W5), effective to remove TOC but ineffective to reduce biotoxicity at two units (W1 and W3), and effective to remove neither TOC nor biotoxicity at one unit (W6). Biotoxicity of wastewater from W6 even increased after the aerobic biological treatment and started to show inhibition to sludge respiration activity. It is proposed that wastewater from W6 should not be discharged directly into biological treatment systems, and wastewater from W1 and W3 should be detoxified before or after the biological treatment. |
