啤酒废水厌氧处理系统的改造

Renovation of Anaerobic Treatment System of Beer Wastewater

对EG SB系统进行问题分析,并实施改进措施。运行结果表明,可有效提高厌氧系统的处理能力和运行稳定性,出水CO D下降至180～320m gL/,去除率稳定在90%以上;采用25gL/左右的厌氧颗粒污泥接种反应器,可在短时间内完成E G SB反应器的再次启动;控制反应器内pH值稳定在6.8～7.2之间,可增加EG SB反应器的运行能力,提高稳定性。(孙悟)

EGSB system was investigated and further renovated. As a result, the renovated system could effectively improve anaerobic treatment capacity and the system stability had been improved greatly with COD in drained water dropped to 180-320 mg/L and removal rate above 90%. The application of 25 g/L anaerobic granule inoculation reactor could finish restart of EGSB reactor in a short time. The pH value in control reactor between 6.8-7.2 could improve EGSB performance and EGSB stability.
