AN APPARATUS ANDMETHOD FOR IMPROVING DEWATERABILITY OF DIGESTED SLUDGE BY SLUDGE CURING

摘要

The present invention discloses an apparatus and method for improving the dehydration properties of digested sludge discharged during anaerobic digestion of high-concentration organic waste. The method for improving dehydration of digested sludge is performed between the anaerobic digestion process of converting organic waste into sludge and the dehydration process of the sludge, and after introducing the sludge into the reaction tank, a predetermined aging temperature is accompanied by stirring. And a sludge aging step of reducing the concentration of organic acids in the sludge by maintaining at the aging time, thereby improving the dehydration efficiency of solid-liquid separation at the subsequent stage, as well as the chemical and biological treatment efficiency of the wastewater composed of the dehydration filtrate. Can be improved.
