绝缘材料厂高浓度有机废水处理技术

TREATMENT OF HIGH CONCENTRATION ORGANIC WASTEWATER FROM INSULATING MATERIAL FACTORIES

针对江苏某绝缘材料厂废水中酚含量高、酚醛摩尔比≤ 1及酚醛缩合后剩余有机物在催化氧化作用下易分解的水质特点 ,采用了二次缩合 +化学氧化 +粉煤灰吸附组合处理工艺。实际运行结果表明 ,该工艺切实可行 ,处理后不仅出水各项指标达到了GB8978 98污水综合排放一级标准 。

A combining process consisting of secondary condensation,chemical oxidation and coal ash adsorption was adopted in the treatment of wastewater from phenolic resin factories in accordance with the water's quality characteristics:its high phenol level,its mole ratio of phenol to aldehyde being equal to or less than 1 and the susceptibility of the residual organics in the phenol aldehyde condensation to catalystic oxidation.The feasibility of the process was already demonstrated by its practical operation results.After treatment by this method,not only did the water reach the first order of Effluent Discharge Standard (GB 8978 98) and a certain amount of phenolic resin was also satisfactorily recovered.
