摘要
采用微电解+ABR+接触氧化工艺进行处理苯甲酸。实验结果表明:采用微电解对废水进行预处理,不仅有效去除了38%的COD,还大幅提高了废水的可生化性;微电解出水经ABR厌氧生物处理,COD去除率达75%;最后经过二级接触氧化处理,出水COD为100以下,达到GB8978-1996《污水综合排放标准》一级标准。
Microelectrolysis-ABR-Contact Oxidation Process was used in the treatment of benzoic acid wastewater.The result showed that the removal rate of COD is about 38 % with-microelectrolysis,and the biodegradability of the wastewater is greatly improved.In ABR,the removal rate of COD was 80 %.After treatment by two-stage contact oxidation,the COD in final effluent was less 100 mg/L,which can meet the first grade discharge standard in 《Integrated Sewage Discharge Standards》（GB8978-1996）.
