白腐真菌处理二硝基重氮酚工业废水的研究

二硝基重氮酚(DDNP)是国内工业雷管应用最普遍的起爆药,白腐真菌生化法处理二硝基重氮酚废水的费用低廉,运行管理较方便。通过摇床处理1000 mL微电解后的二硝基重氮酚废水,取得了较好的结果。经白腐真菌处理后,出水CODcr为131 mg/L左右,硝基化合物<0.2mg/L,苯胺类化合物<0.1 mg/L,CODcr去除率在71%左右;总CODcr去除率在94%以上。出水CODcr达到国家二级综合排放标准,出水色度、硝基化合物和胺基化合物达到国家一级综合排放标准。

The Study on the White Rot Fungus in Treating the Wastewater from Diazodinitrophenol Production

Diazodinitrophenol(DDNP)is a normal primary explosive used in the national industry detonators.The expense of using white rot fungus to treat DDNP wastewater is cheap and the management is easy.The result of 1 000 mL micro-electrolysis DDNP treated through shaking culture was that CODcr,the quality of aniline compounds and the quality of nitro compounds of discharge water were separately about 131 mg/L,below 0.1 mg/L and below 0.2 mg/L respectively.The CODcr of discharge water reached the national second integrated wastewater discharge standard,and the quality of aniline compounds and nitro compounds both reached the national first integrated wastewater discharge standard.
