Biodegradability Assessment of Industrial Wastewater by Warburg Respirometer
Biodegradability of 5 kinds of industry wastewater (food-processing wastewater, coking plant wastewater, paper mill wastewater, kier wastewater and black liquor in paper industry) was studied using Warburg respirometer and simulated oxidation pond. Results showed a positive correlation exists between the oxygen consumption rate R％ and the ratio of BOD5/COD. Treating industrial wastewater by oxidation pond, the COD removal efficiency η％ of each wastewater was calculated. Among the three parameters, interrelated coefficient of R％ and η％ is 0.9593, while the value of BOD5/COD and η％ is only 0.7881 which indicating R％ could be used to evaluate the biodegradability of industrial wastewater.
