TURBID WATER TREATMENT APPARATUS

PROBLEM TO BE SOLVED: To provide a turbid water treatment apparatus constituted so as to automatically meter and supply a floccurant not only to enhance the efficiency of the treatment of turbid water but also to flocculate flocs without using a sedimentation tank to reconcile the compactification and efficiency of the apparatus. SOLUTION: The turbid water treatment apparatus is constituted of a neutralization treatment device 15 for blowing carbon dioxide in turbid water to neutralize the turbid water, flocculant tanks 16, 17 and 19 for storing a flocculant solution, a flocculant automatic supply device 18 for automating a series of processes from the metering and dissolution of the flocculant to the automatic supply of the flocculant solution to the flocculant tanks 16 and 17, and a flocculation device 20 having spiral type line mixers 60a and 60b for stirring and mixing the flocculant charged from the flocculant tanks and the neutralized turbid water and flocculating the floating matter in the turbid water to accelerate floc forming reaction.
