摘　　要：以化粪池粪便污泥为研究对象,采用中温(35℃)厌氧消化,研究了投加复合微生物制剂HBH-Ⅱ对总固体(TS)、挥发性固体(VS)和COD减量效果的促进作用以及氨氮值的变化情况。结果表明:经过20 d的厌氧消化,对TS、VS和COD的去除率均以投量为0.05%的最大,分别达到36.43%、49.11%和46.97%,分别比对照的高9.75%、12.06%和13.14%。经处理后,NH4+-N含量均低于厌氧消化的抑制浓度(2 000 mg/L)。因此,在实际工程中可通过投加HBH-Ⅱ来提高对化粪池污泥的厌氧消化效率,实现减量化。Taking the nightsoil sludge from septic tank as research object, the effect of adding HBH-Ⅱ , a compound microbial preparation, on the removal rates of total solids （TS） , volatile solids （VS） and COD as well as the change in NH4^＋ -N content were investigated using mesophilic anaerobic digestion at 35 ℃. The results indicate that after the anaerobic digestion for 20 days, the maximum removal rates of TS, VS and COD are 36.43%, 49. 11% and 46.97% at HBH-Ⅱ dosage of 0.05%, which are 9.75%, 12.06% and 13.14% higher than the control values, respectively. The NH4^＋ - N content after treatment is less than the inhibition concentration （2 000 mg/L） of anaerobic digestion. Therefore, adding HBH- Ⅱ can improve the anaerobic digestion efficiency of nightsoil sludge from septic tank, thus realize the sludge reduction.
