摘要： A sludge treatment process including: adjusting sludge to a particle diameter of more than 2 mm to 45 mm or less; a step of pyrolyzing the adjusted sludge in a low-oxygen or oxygen-free atmosphere and at a temperature of 350° C. to 500° C.; and a step of combusting a gas generated in the pyrolysis. Such process may be used to decompose harmful compounds and maximize the efficiency of the process.

摘要： The present invention relates to a method of preparing a polyphenylene sulfide and a high-viscosity polyphenylene sulfide prepared using the method. In this method, the ratio of an organic phase to an aqueous phase is controlled by controlling dehydration conditions, so that high viscosity may be realized without adversely affecting a reaction or physical properties during preparation of the polyphenylene sulfide.
