| Abstract: | A special strain of microorganism with high flocculating activity TH6 has been screened and cultured using the recirculated sludge from an activated sludge wastewater treatment system of a chemical plant. It was identified as Aspergillus niger, which has been cultured for 64h with shake speed of 150r/min at pH6.0, temperature of 30℃, using sucrose as carbon source and NaNO 3/urea as nitrogen source. Investigation results showed that among the main constitutes responsible for flocculation of TH6 are polycarbohydrates. |
