The wastewater fully mixed with the chemical flows into the first central tube 310 with the floc second stirring sub-tank 260, enters the first settling tank 300 through the first central tube 310, is uniformly distributed through the overflow weir around the upper part and flows into the second central tube 410, and in the process, the floc in the water continuously settles to the bottom of the first settling tank 300 and is gathered into a layer of bottom mud. As the bottom sediment is continuously raised to a designated position, the first detector 330 feeds back a signal, and the first switching valve 340 and the sludge pump 500 are turned on. As the first mud scraper 320 continuously conveys the bottom mud to the bottom mud outlet, the bottom mud is cleaned to a lower position. The first switching valve 340 and the sludge pump 500 are closed by the feedback signal of the first detector 330. The wastewater with a small amount of flocs enters the central pipe of the second settling tank 400 through the overflow weir, the settling time of the flocs is reduced under the action of the settling inclined plate 430, and a small amount of flocs in the water is further separated and removed. Because the water flows through the settling sloping plate 430 and undergoes two-stage settling, most of the flocs are settled and removed, and a small amount of residual fine flocs are separated onto the settling sloping plate 430 during the process of flowing through the settling sloping plate 430. The times of cleaning and maintenance of the sedimentation inclined plate 430 can be reduced to the maximum extent while the water outlet effect is ensured. Mud passes through second detector 450 in the second sedimentation tank 400, second ooff valve 460 and sludge pump 500 get rid of, second stirring pond 200 has mud return opening 240, mud return opening 240 is located the bottom of second stirring pond 200 and is close to the water inlet of second stirring pond 200, the back flow sets up the backwash valve, the play mud mouth of back flow intercommunication sludge pump 500, through the reflux valve aperture on the control backflow pipeline, adjust the flow of backward flow mud, the medicament that does not participate in the reaction among the part bed mud of utilizing first sedimentation tank 300 and second sedimentation tank 400 carries out the secondary retrieval and utilization.
