EXCREMENT DISPOSAL SYSTEM

摘要

PURPOSE: An excrement disposal system is provided to pre-treat excrement for minimize loading of biological and advanced treatment. Therefore biological and advanced treatment processes are operated without dilution water. CONSTITUTION: Adulterated matter and grit of excrement is removed by a screen(2) and a grit chamber(3). And excrement is flowed a reservoir(6). In the reservoir(6), organics is transformed into humus soil by decomposing reaction. The decomposing reaction is operated by mixing of activated mineral, organics of excrement, and oxidized water of an oxidation tank. Discharged excrement form the reservoir(6) is passed to a stripping tank(11) for ammonia stripping at pH 12 and over. Continuously neutralization and coagulation are operated in a neutralization/coagulation tank(12)(14). And excrement is dewatered by a vibrating compressor(16) and dewatering system(18). Separated water is passed to biological and advanced treatment processes.
