摘要:
采用厌氧折流板反应器(ABR)处理精对苯二甲酸(PTA)生产废水,研究冲击负荷对反应器运行性能的影响。经过110 d的运行,在容积负荷为3.60~5.76 kg/(m3·d)条件下,ABR反应器对化学需氧量(COD)的去除率为67%~81%,表明ABR反应器处理PTA废水具有较高的处理效能和运行稳定性。冲击负荷过程中,第1格室COD去除率显著减小,而其他格室COD去除率均略有增加; 此外,沿着水流方向各格室中挥发性脂肪酸(VFA)浓度和氧化还原电位(ORP)依次减小,pH依次增加,表明ABR反应器的分室化结构为PTA废水处理提供了良好的厌氧相分离环境和运行稳定性。
Abstract:
The treatment of purified terephthalic acid wastewater(PTA)was conducted in an anaerobic baffled reactor(ABR).The effects of shock loading on the performances of ABR were studied.After 110 d of operation,the removal efficiency of chemical oxygen demand(COD)ranged from 67% to 81% at 3.60-5.76 kg/(m3·d)volume loading,indicating that ABR had high removal efficiency of PTA wastewater and excellent stability to shock loads.The COD removal efficiency markedly decreased in the 1st compartment when the volumetric loading rate increased,but kept increasing in the following compartments.Additionally,the concentration of volatile fatty acid(VFA)and the oxidation-reduction potential(ORP)reduced,and the pH value increased in the latter compartments.The results demonstrated that the compartmentalization provided well staged multi-phase anaerobic environment and had good stability to treat PTA wastewater.
