Title:
PROCESSING METHOD AND PROCESSING SYSTEM OF CONTAMINATED MUDDY WATER
Document Type and Number:
Japanese Patent JP2017124359
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a processing method and system of contaminated muddy water that has a simple apparatus structure and is easy to deal with large throughput compared with conventional magnetic separation or centrifugal separation.SOLUTION: A processing method of contaminated muddy water includes a step S06 for mixing object contaminated muddy water with iron powder, a step S07 for separating the iron powder from the muddy water mixed with the iron powder by gravity separation, and a step S08 for recovering the separated iron powder. The muddy water mixed with the iron powder is transported to a gravity separation unit having a large cross-section area through a water pipe having a small cross-section area. The iron powder precipitates from the muddy water mixed with the iron powder in the gravity separation unit.SELECTED DRAWING: Figure 1
