ABSTRACT
Based on the analysis of the current situation of sewage sludge treatment and common sewage sludge treatment schemes in China, the aeration tank sludge of a sewage treatment system in a city was taken as the test object to carry out experimental research on the dewatering performance of activated sludge settlement. Based on the simulation of an aeration tank and sedimentation tank environment, the influence of temperature conditions on the settlement and dewatering performance of activated sludge was analyzed, and it was found that the settlement performance of activated sludge decreased in the low-temperature environment below 15°C.
