| 摘 要： | 以火山岩为载体,制作了内循环式厌氧生物流化床,通过好氧预挂膜、快速排泥、逐步提高负荷法启动,启动时间约47 d。运行稳定后,当精对苯二甲酸(PTA)废水的COD为(4 752.3±41.2)mg/L时,在水力停留时间(HRT)为(17.3±1.2)h、有机负荷(OLR)为6.5kg COD/(m3.d)条件下,COD去除率达(64.0±4.4)%,对苯二甲酸(TA)去除率达(65.1±1.3)%,生物膜量达(13.3±0.2)mgVSS/g载体。对载体进行扫描电镜分析(SEM)得知,载体内为封闭孔,厌氧生物主要生长于载体表面孔内。观测产量为Yobs0.057gVSS/g COD,载体生物基质利用速率为0.83g COD/(gVSSd)。

| Abstract: | Using lava rock as carrier,the anaerobic bi-oreactor is set up with the method of aerobic precoating treatment of carrier and rapid clean up of sludge.The start-up phase is 47 days.In the operation period,when the COD of PTA wastewater is(4 752.3±41.2) mg/L,the HRT of the AFBR is(17.3±1.2) hours and the organic loading rate(OLR)is 6.5 kgCOD/(m3·d),the COD removal rate and TA removal rate are(64.0±4.4)% and(65.1±1.3)%,respectively.The biomass on the carrier is(13.3±0.2) mg VSS/g carrier.Analysed by scanning electron microscope(SEM),the interior pores of the lava rock is hermetic and the anaerobes is mainly grown in the pores of exterior surface.The observed sludge yield(Yobs) is 0.057 g VSS/g removal COD and the carrier substrate utilization is 0.83 g removal COD/(g VSSd). |
