摘要
某市政污泥处理示范工程处理规模为5t/d,采用热水解+厌氧消化工艺。近一年的稳定运行表明,厌氧消化过程的甲烷产量约6m^3/d,甲烷最高产率可达353L/kgVS,污泥中有机质降解率为29.68%,TOC降解率为21.7%,能较好地实现污泥的稳定化与资源化。
A demonstration project of municipal sludge treatment with scale of 5 t/d was built using thermal hydrolysis and anaerobic digestion process. About one year' s steady operation of the project showed that the methane production in anaerobic digestion process was about 6 m^3/d, the maximum methane yield could reach 353 L/kgVS, the degradation rate of VS/TS in sludge was 29. 68%, and the reduction rate of TOC was 21.7%. It indicated that this technology efficiently had realized the stabilization and resource utilization of the sludge.
