Description

technical field [0001] The invention relates to the technical field of sewage treatment systems, in particular to a sewage treatment system based on a frequency converter. Background technique [0002] At present, the discharge of urban domestic sewage is the main pollution source of urban water in China, and the treatment of urban domestic sewage is the top priority of urban water conservation and urban water environment protection at present and in the future. This requires us to take the construction of domestic sewage treatment facilities as a priority The important content of urban infrastructure is to be grasped, and it is a matter of urgency. The current direct utilization of sewage: With the progress of human society and the development of science and technology, the direct utilization of sewage has become possible, and the sewage source heat pump system is used to utilize urban primary sewage. [0003] With the improvement of environmental protection requirements a...
