中文摘要: 为了能经济有效地处理山东某一化工厂的3,4,5-三甲氧基苯甲醛生产废水,首先采用间歇式实验对车间生产废水进行厌氧可生化性评价。然后以此为基础,采用单级中温UASB,用二沉池的污泥为接种污泥,保持水力停留时间(HRT)不变,通过逐步提高进水COD的方式,考察在COD容积负荷(OLR)从1.0 g ·(L·d)~(-1)逐步升高至10.0 g·(L· d)~(-1)的情况下,反应器处理效果的变化。在140 d的连续实验过程中发现,最优的OLR在6.0 g ·(L·d)~(-1)(进水COD 6 000 mg·L~(-1)左右),COD 去除率能稳定在60.3%,出水pH值稳定在7.4到8.0之间,VFA在500 mg·L~(-1)左右。实验结果表明,UASB 处理该制药厂废水是可行的。

英文摘要: In this study,with the aim of finding an economic and effective option for treating 3,4,5 -trimethoxybenzaldehyde manufacturing wastewater from a chemical industries,Ltd., the anaerobic biodegradability of the wastewater was evaluated by a series of batch experiments. Based on the experimental data, the anaerobic treatment of the wastewater was investigated,using a single UASB,with activated sludge as seeding sludge. The influence of the organic loading rate(OLR) on the performance of the reactor was evaluated, from an initial 1. 0 g·(L·d)~(-1) to a maximum of 10. 0 g ·(L·d)~(-1),by step-increasing the influent COD with unaltered HRT. During 140 days of continuous operation, it was observed that the optimal OLR was 6. 0 g·(L·d)~(-1) when the influent COD was approximately 6 000 mg·L~(-1),corresponding to a 60. 3% COD removal rate. The respective values of pH and VFA in the effluent were approximately 7. 4 and 500 mg·L~(-1) . The experimental data during the long-term experimental run indicated the feasibility of UASB for treating of 3,4,5-trimethoxybenzaldehyde manufacturing wastewater.
