Abstract
The invention discloses a hydraulic separation method used for pipeline sludge, and a system thereof. The method comprises the following steps: large-particle size particles are separated from ground sludge powder by adopting a vibration screen, and small-particle size particles obtained after vibration screening are added to water; the small-particle size particles in water are processed with water to generate parts of suspending substances and floating substances; the suspending substances downward settle and are filtered through a filter screen, and the floating substances are eliminated through a water draining tube; the suspending substances filtered through the filter screen settle to the bottom of water, and the obtained precipitate is sent to a sand removal device through a pump, and undergoes sand removal; cyclone sand removed isolate falls to a sand barrel and is stored, and separated water is used in flushing after being filtered; and the floating substances go through a pipeline, enter a solid-liquid separator, and are separated, and superfluous sludge on the vibrating screen is recovered, and then goes through the vibration screen. The method and the system have the advantages of great saving of water resource consumption, increase of the treatment efficiency, prevention of artificial contact with sludge, and effective improvement of the safety effect.
