NON-DEGRADABLE SEWAGE AND WASTEWATER PRE-TREATMENT SYSTEM

摘要

Disclosed is a non-degradable wastewater pretreatment system. The non-degradable wastewater pretreatment system of the present invention includes: a solid-liquid separator which processes the waste, sediment, and floating matter of wastewater; and a fine matter filtration tank which is connected to the solid-liquid separator by a connection flow path, and filters and purifies fine matter. The solid-liquid separator includes: a main body which has an inlet unit, where wastewater flows, in at one side part and a first sludge discharge unit to discharge sedimentation sludge on the bottom surface; a separation film member which is installed to be extended from the center of the bottom part of the main body to the upper part in order to divide the inside of the main body into a first partition and a second partition; a moving flow path which is formed in the upper side of the separation film member and enables treatment water to move; and an opening and closing cover unit which is positioned in the upper part of the main body and can be opened and closed by being combined with a hinge unit at one side to be able to rotate through hinge. The fine matter filtration tank includes: a housing which has a second sludge discharge unit to discharge sludge at the lower part; and a membrane unit which is installed in the housing. The non-degradable wastewater pretreatment system enables a filtration device to be used for long time by effectively performing the backwashing of the membrane unit.
