SYSTEM AND METHOD FOR TURBID WATER TREATMENT

摘要

PROBLEM TO BE SOLVED: To provide a system and a method for turbid water treatment being capable of economically treating a large amt. of turbid water and capable of reducing construction cost. SOLUTION: A turbid water treatment system has an on-the-spot mounting type raw water tank 1 into which turbid water containing a soil particle component and a water component is introduced, and on-the-spot mounting type stirring tank 2 receiving the turbid water supplied from the raw water tank 1 and a soil particle flocculation accelerator supplied to stir and mix them to form a mixed liquid, an on-the-spot mounting type sedimentation tank 3 receiving the supply of the mixed liquid to sediment soil particle flocs formed by the reaction of the soil particle component and the soil particle flocculating accelerator to form sludge, an on-the-spot mounting type sludge treatment tank 4 receiving the sludge sedimented in the sedimentation tank 3 and a modifier to stir and mix them and modifying the properties of the sludge to form modified soil and the water permeable retaining wall 5 fixed on the sludge treatment tank 4 and separating moisture in the modified soil to discharge the same.
