The invention provides a circulating water treatment and wind power generation comprehensive utilization system. The invention adopts circulating water pressure of rivers, ,lakes, and sea water and municipal sewage to generate electricity and purify water, and arranges a generating system and a water treatment system on circulating pipelines to fully utilize water pressure of the circulating pipelines to push a triple axis turbine system; the turbine rotated by the water pressure drives a gear box to rotate and is connected with a wind power generator to allow the wind power generator to achieve the aim of steady generation with rated speed; meanwhile, a turbine shaft is connected with a river, lake, sea water and municipal sewage purification system; after purification, the water returns to the rivers and lakes by adopting a pipeline pump of an effluent pressure pump station. The system integrates the water purification and power generating, has the obvious advantages of energy conservation, environmental protection and large water treatment capacity, and fills the blank that the rivers, lakes, sea water and municipal sewage can not adopt a uniform cycle operation technology at home and abroad at present.
