Title:
MIXING, STIRRING AND RESIDENCE APPARATUS
Document Type and Number:
Japanese Patent JP2015013267
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an energy-saving and space-saving apparatus capable of simply controlling an addition amount, reaction time, and residence time of drug in a wastewater treatment apparatus that performs chemical treatment by drug.SOLUTION: In a wastewater treatment apparatus that performs chemical treatment by drug, drug is continuously added to raw water using only liquid feeding power of the raw water, and the drug is stirred by generating spiral water flow in the treatment tank by the liquid feeding power, and reaction time of drug is controlled by controlling residence time by the capacity of a treatment tank. Dynamic water pressure and static water pressure in a raw water piping, which are generated only by the liquid feeding power of the raw water, control a mixture amount of the drug, and a pore diffusion membrane is used as a barrier membrane in some cases.
