Current Situation and Movement Management of a Sewage Treatment Plant in Winter

In this paper, the Author introduced basic survey and main equipment of Huaian Sijiqing Sewage Treatment Plant briefly, elaborated that the A aeration tank and the B aeration tank present the different questions and the present situation in view of winter sleety weather and low temperature in winter, obtained the biological activity relative value along with the water temperature change curve according to target and so on sludge load, efficiency changes, meanwhile enumerated the unusual situation which to the construction, the mechanical device and the measuring appliance once appeared, proposed some feasible countermeasure and the preventive measure, like supported and maintained the mechanical device ahead of time, enlarged A, B section of sludge reflux ratio in the winter, guaranteed the microorganism to occupy the good condition, achieves the draining water standards.
