Textile sewage segment treatment structure and sewage treatment method

The invention discloses a textile sewage segment treatment structure and a sewage treatment method. The structure comprises a sewage pool with a sewage inlet, a main treatment pool, multiple positioners used for inducting the sewage level and sequentially arranged in the sewage pool from top to bottom, multiple pneumatic valves arranged sequentially from top to bottom, and an air compressor for controlling the pneumatic valves to be switched on or off. The sewage pool and the main treatment pool are communicated through the pneumatic valves. The method mainly includes the following steps of settling, middle-layer sewage separating, filtering, chemical treatment, physical treatment and water use permission. Middle-layer sewage is subjected to selective segment treatment, investment is low, operation is convenient, the treatment efficiency is improved, the treatment cost is reduced, and good application prospects are achieved. 本发明公开了种纺织污水分段处理结构及污水处理方法，其包括设有污水进水口的污水池、主处理池，所述污水池内由上至下依次设置多个用于感应污水水位的定位器、由上至下依次设置多个气
