TREATMENT SYSTEM AND METHOD FOR WASTE LIQUID CONTAINING CARBON DIOXIDE CAPTURING ABSORBENT

The present application belongs to the technical field of waste liquid treatment and, in particular, relates to a treatment system and method for a waste liquid containing a carbon dioxide capturing absorbent. The treatment system comprises a flocculation device and a membrane separation device, wherein waste liquid and a flocculant are mixed in the flocculation device to form a mixed liquid, and the membrane separation device is in communication with the flocculation device; the membrane separation device comprises a plurality of ceramic membrane assemblies, and the ceramic membrane assemblies are vertically arranged; and each ceramic membrane assembly comprises a ceramic membrane, and the flow direction of the mixed liquid is perpendicular to the ceramic membranes. The treatment system is suitable for treating a washing waste liquid with a very low content of a carbon dioxide absorbent, and the treatment capacity is large (the daily treatment amount of each ceramic membrane can reach 150 m2) and the treatme
