The present application relates to sewage treatment technical field, especially to a kind of sewage treatment device of water conservancy project.The present application aims at overcoming the shortcomings that suspended solids precipitation process time is longer, and precipitate is easy to secondary pollution sewage in the process of cleaning sedimentation tank.The technical implementation scheme of the present application is: sedimentation tank, the sedimentation tank is opened in upper portion and is located in the lower portion of sewage discharge port of sewage discharge port located in its upper portion, the sedimentation tank is opened in lower portion;Rotary outer tube, the movable setting of rotary outer tube is in the bottom of sedimentation tank;Venturi tube, the outer wall of rotary outer tube is provided with venturi tube, and the venturi tube has several ones.The present application is provided with venturi tube, and venturi tube simultaneously sprays flocculating agent and air, so that flocculating agent blows air into fine bubbles, flocculating agent becomes flocculating group and adheres to pollutant and floats on the surface of sewage, while improving the efficiency of sewage treatment, it is convenient for staff to handle the pollutant adhered by flocculating group in time, thereby avoiding secondary pollution of pollutant to sewage.

The utility model discloses an efficient spiral-flow type sewage treatment precipitation device, which relates to the technical field of sewage treatment, and comprises a box body, a cyclone is arranged at the upper part in the box body, a connecting frame is connected to the upper part of the outer wall of the cyclone, the back surface of the connecting frame is connected with the box body, a water inlet is connected to the upper part of the outer wall of the cyclone, and a water outlet is connected to the lower part of the outer wall of the cyclone. And a water outlet is formed in the top of the cyclone. According to the utility model, through the arrangement of the swirler, the connecting pipe, the drain pipe, the floating plate and the like, after sewage is treated by the swirler, large-particle objects enter the storage screen frame, water flow is input into the connecting pipe through the water outlet, enters the drain pipe and is discharged to the bottom end of the inner side of the box body, and the water flow is pressed by the floating plate with certain gravity, so that the large-particle objects enter the storage screen frame; the outer wall of the floating plate is limited by the sliding block and the inner wall of the box body, so that the floating plate has the capability of quickly flattening the shaking water surface, and fine particles in water can be conveniently precipitated under the action of the gravity of the fine particles.
