| 中文摘要 |
| 某煤气站含酚废水剩余活性污泥中可生化处理的MLVSS浓度占总MLVSS浓度的59.3%.采用好氧消化处理,在30℃条件下间歇运行17天,MLVSS的降低可达44.9%.提高温度时,污泥降解速率亦提高,但转入液相的难生物降解产物也增加.本文还对剩余活性污泥好氧消化动力学进行了推导,并提出了其动力学常数的简捷求定方法。 |
| 英文摘要 |
| This paper discusses the feasibility for the treatment the xecess activated sludge of gas wastewater by aerobic digestion technique. Test results show that 59.3% of the total MLVSS is biodegradable in the sludge, 44.9% of MLVSS is removed when test is conducted for a period of 17 days under 30℃. The sludge degradation rate and the non-biodegradable material concentration in the liquid phase would increase when the reaction temperature is raised. Study on the kinetics of sludge aerobic digestion is also conducted and a method for the deduction of kinetic constants is proposed. |
