Abstract (2. Language): 
Based on the stir and separation, a new method is put forward to clean the deposit in sedimentation pool. Using the similarity theory in the design of experiment rig simulated a sedimentation tank clean-up system. The rationality of developing the industrial recycled water clean-up system was verified by theoretical analysis and numerical simulation (CFD) and the method to test “3D” research problems in the laboratory PIV flow field. In order to ensure the accuracy of the verification, the numerical simulation and PIV experimental model were designed at the ratio of 1:1. Results indicate that the mixture coefficient of muzzle is about 0.7;in different pressure conditions. The fluid boundary which spouted from combing tube can be regarded as a line and it has same angle with the combing tube. Experiment data also indicate that water speed is below 0.1 m/s on top of muzzle 1m zone. Axial velocity of fluid spouted from muzzle is measured and empirical formula is put forward. The best distance is 200mm between muzzles which determined by experiment, which ensures the level of clear water at the upper layer of the sedimentation tank, meeting the demand for industrial water.
