BR处理低浓度废水的启动方式研究
On the Start-up Styles of Anaerobic Baffled Reactor Treating Low Strength Wastewater
通过试验,对ABR处理低浓度废水的启动方式进行了研究。试验研究表明:固定HRT、逐步提高进水CODcr浓度的启动方式,可使ABR 90d完成启动,其对CODcr的去除率达到80%,系统运行较稳定,但污泥颗粒比较松散;而固定进水CODcr浓度、缩短HRT的启动方式,49d可使ABR的 CODcr去除率达到80%,且污泥颗粒化程度较高。
he start-up styles of the anaerobic baffled reactor(ABR) treating low strength wastewater were studied by the experiment. The results showed that it took 90d’s to complete the start-up by the form of enlarging the feed concentration gradually at constant hydraulic retention time(HRT). Up to 80% of the CODcr was removed and the system operation was stable,but the structure of granular sludge was loose. On the other hand, it took 49d’s to complete 80% CODcr removal, with higher degree of granulation, by the form of reducing the HRT at constant CODcr concentration.
