WATER TREATMENT SYSTEM

摘要

This water treatment system includes a water intake section 8 for taking in a raw water containing a water-soluble polymer; a stirring unit 1 for stirring the raw water flowing into the unit from the water intake section 8; a separating unit 2 for separating a solid from the raw water after the stirring; a viscosity measuring section (5,6,50) for measuring the viscosity of the raw water flowing in the stirring unit 1, and that of the raw water after the stirring; and a control unit 4 in which on the basis of a result measured through the viscosity measuring section and a predetermined target viscosity, a control is made about the amount of an additive to be charged into the stirring unit 1, and/or the stirring intensity of the stirring unit. Thus, the viscosity of the raw water is adjusted.

1. A water treatment system, comprising:
a water intake section for taking in a raw water containing a water-soluble polymer; a stirring unit for stirring the raw water flowing into this unit from the water intake section; a separating unit for separating a solid from the raw water after the raw water is stirred; and a viscosity measuring section for measuring the viscosity of at least one of the raw water flowing in the stirring unit, and the raw water after the stirring, wherein on the basis of a result measured through the viscosity measuring section, a decision is made about at least one of the amount of an additive to be charged into the stirring unit, and the stirring intensity of the stirring unit.
