Although the raw materials for producing sodium hydroxide are added to the sedimentation tank 1 through the sludge addition port 3 and the waste liquid addition pipe 4, and a sufficient amount of alkali solution is added thereto, and then the first motor and the second motor are turned on to rotate, driving the first spiral mixing rod 27 and the second spiral mixing rod 28 to rotate, and stirring is started from the bottom of the sedimentation tank 1. After a certain stirring and mixing process, the rotation of the first motor and the second motor is stopped, and then the mixture inside the sedimentation tank 1 is left to stand.

[0030] Compared with the prior art, the utility model is provided with a liquid-separating telescopic rod 13 to drive the fixed grid 8, the water filter cloth layer 9 and the drain pipe 10, and utilizes the filtering characteristics of the water filter cloth layer 9 to achieve the purpose of separating the sludge in the sedimentation layer from the upper clear liquid, avoiding the sedimentation layer sludge from being lifted up again and mixed during the drainage process, so that the drain pipe 10 can more easily and conveniently complete the task of extracting the upper clear liquid.
