摘要Oxygen consumption (OC) for the combustion of dried sewage sludge was determined by an equipped YSZ oxygen sensor. Probably due to the good combustion of the sludge, it was not affected by the temperature and oxygen concentration. However, it increased directly proportional to the rise of sludge amount. The mole ratio of OC/TOC agreed well with each entry and almost equalled 1, which indicated the feasibility of directly using OC to assess the organic burden in the wastes. As a result, OC in this study can be potentially applied to replace the chemical oxygen demand (COD) for the evaluation of samples involving solid-containing wastes (e.g., sewage sludge). Additionally, the easy determination of OC also promotes its advantage over COD because of the unavoidable drawbacks for the conventional COD determination.
