Evaluation of 'Within-Vessel' Sewage Sludge Composting Systems in Europe

摘要

The objectives were: (1) To update a review of the state of the art of sewage sludge composting in Europe; (2) to evaluate a European-designed, continuous, thermophilic, mechanical, aerobic, composting system in Germany; and (3) to compare its cost to those of the U.S. Department of Agriculture's Beltsville static-pile, aerated composting system. This report addresses the general characteristics of the European composting systems and a bioreactor in Hochheim am Main, West Germany.
