To evaluate the performance of microwave (MW)-chemical hybrid sludge treatment system, a pilot scale MW disintegration unit (treatment capacity of 500L/d) was constructed. The results showed that organic matter, nitrogen, and phosphorus were effectively released from the MW-pretreated sludge. The values of COD released were 15.91%, 15.07%, 13.83%, 19.35%, and 15.07% for the MW, MW-acid, MW-alkali, MW-H2O2, and MW-H2O2-alkali treatment processes, respectively. Additionally, for a wastewater treatment system with a capacity of 200m(3)/d, when coupled with a MW sludge pretreatment unit, the sludge production and sludge yield were greatly reduced by 38.60% and to 0.35kg VSS/kg CODconsumed, respectively. The total operating cost of the lysis-cryptic growth system was 13.64% lower than that of the CAS system without a MW unit.
为了评估微波（MW）-化学联合污泥处理系统的性能，构建了一个中试规模的 MW 消解单元（处理能力为 500L/d）。结果表明，MW 预处理污泥能够有效地释放有机物、氮和磷。MW、MW-酸、MW-碱、MW-H2O2 和 MW-H2O2-碱处理过程中释放的 COD 值分别为 15.91%、15.07%、13.83%、19.35%和 15.07%。此外，对于一个处理能力为 200m(3)/d 的废水处理系统，当与 MW 污泥预处理单元耦合时，污泥产量和污泥产率分别降低了 38.60%和 0.35kg VSS/kg COD 消耗。裂解-隐生长系统的总运行成本比没有 MW 单元的 CAS 系统低 13.64%。
