Then enters the slow stirring reaction zone 9 through a baffling water weir 12, wherein the baffling water weir 12 consists of a plurality of vertical plates which are staggered with each other; the second stirring paddle 15 in the slow stirring reaction zone 9 is used for slow stirring, and the rotating speed of the second stirring paddle 15 during slow stirring is usually 100 and 300 rpm; when the slow stirring reaction area 9 is used for slow stirring, the powder is fully contacted with pollutants in the sewage in order to further react the mixed liquid generated in the first stage, so that the reaction between the powder and the pollutants is fully exerted, and the water body and the pollutants are separated to be used as a second-stage separation treatment device.

Wherein the baffled water weir 12 is a water passage for connecting the fast stirring reaction zone 7 and the slow stirring reaction zone 9. The baffling effluent weir 13 consists of a plurality of vertical plates which are staggered with each other; the baffling effluent weir 13 is a water passing channel used for enabling mixed liquid after powder reaction treatment to enter a subsequent sewage treatment unit in a self-flowing mode.
