AnMBR处理红霉素生产废水的启动研究
Efficient start-up of erythromycin production wastewater treatment in AnMBR
摘要
Abstract
By using erythromycin production wastewater with enhanced hydrolysis pretreatment,anaerobic sludge from different sources were mixed and used as inoculum to evaluate their methane production performance under anaerobic conditions.The selected mixed sludge was then inoculated into an anaerobic membrane bioreactor(AnMBR)to investigate the operational performance and microbial community composition during reactor start-up.Results showed that the addition of pharmaceutical anaerobic sludge to municipal anaerobic sludge significantly improved methane production efficiency.When the AnMBR is inoculated with a 7∶3 mass ratio of municipal anaerobic sludge and pharmaceutical anaerobic sludge,under a COD loading of 2 g/(L·d)and a hydraulic retention time(HRT)of 5 d,the COD removal efficiency reaches(72.80±6.89)%,with the biogas production of(2.27±0.10)L/d and methane content of(72.57±3.12)%in the gas composition.During AnMBR start-up,at the phylum level,the dominant microbial taxa were Bacillota,Chloroflexota,Bacteroidota,Halobacteriota and Thermoproteota.At the genus level,the key microbial populations included hydrolytic-acidogenic bacteria such as Anaerolineacea,Aggregatilinea,and Christensenellaceae_R-7_group,as well as the methanogenic archaeon Methanothrix.关键词
