PURIFICATION METHOD AND PURIFICATION APPARATUS FOR CONTAMINATED FLUID

摘要

PROBLEM TO BE SOLVED: To provide a purification method of a contaminated fluid with facilitated post-treatment without requiring a process for separating the contaminated fluid such as a contaminated slurry containing Volatile Organic Compounds (VOC). SOLUTION: A purification apparatus M1 is equipped with a notch tank 1 wherein a VOC contaminant is stored. A gas mixing jet pump 2 is connected to the notch tank 1, and the VOC contaminant stored in the notch tank 1 is supplied to a jet nozzle of the gas mixing jet pump 2 by a pressure pump 3. Furthermore, a contaminated slurry introduction pipe in the gas mixing jet pump 2 wherein the VOC-contaminated slurry is separately sucked is airtightly connected to the notch tank 1. The VOC-contaminated slurry is sucked in the contaminated slurry introduction pipe by a negative pressure generated by the jet water J jetted from the gas mixing jet pump 2, thereby the VOC-contaminated slurry is mixed with the jet water J.
