PROBLEM TO BE SOLVED: To provide a method for handling a (meth)acrylate containing liquid which suppresses the generation of sludge, prevents the deterioration of the liquid-liquid separation efficiency and the lowering of the distillation efficiency in the latter process and realizes a long continuous and stable operation, for cyclical use, for the former process of wastewater or a wastewater solution obtained by recovering available components after treating in any one, two or more processes of cleaning, neutralization and extraction, in the method for handling (meth)acrylate containing solution which is treated in any one, two or more processes above described. SOLUTION: In the cyclical use of the wastewater or the wastewater solution for a former process, solid contents are removed after cooling to 10-50°C. COPYRIGHT: (C)2005,JPO&NCIPI
