摘要
对ABR处理低浓度有机废水的启动方式进行了试验研究。结果表明:固定HRT、逐步提高进水COD浓度的启动方式,可使ABR反应器于90 d内完成启动,其对COD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COD浓度、缩短HRT的启动方式,49 d就可使ABR对COD的去除率达到80%,且污泥颗粒化程度较高。
The effect of the start-up mode of the anaerobic baffled reactor （ABR） on the treatment of low-strength organic wastewater was studied. The results show that it takes 90 days to complete the start-up when the influent COD concentration is gradually increased, and the hydraulic retention time （HRT） is kept constant. The removal rate of COD is 80% , and the system operates stably, but the structure of the granular sludge is loose. On the other hand, when the COD concentration is kept constant and HRT is gradually reduced, it takes only 49 days to reach 80% COD removal, and the granulation degree of sludge is also higher.
