合成樟脑系列废水预处理试验

研究了去除合成化工厂废水中樟脑及其系列产品———富马酸等有机合成化合物的方法 .根据实际废水的水质采取分别预处理工艺 ,试验表明 ,采用混凝气浮法去除难溶、难降解、对微生物有抑制性的樟脑等疏水性油类物质 ,效果良好 ,COD去除率在 70 %以上 ;选择微电解法和进行氧化剂氧化 -还原作用后 ,可分解废水中难降解有机物 ,改善废水的可生化性 ,降低COD值 .

Pretreatment on Camphor-series Chemosynthesis Wastewater

The wastewater produced in a certain chemical synthesis factory contains a series of organic compounds based on camphor and fumaric acid.Respective pretreatment processes were adopted according to different wastewater quality in this article.Coagulation and air floatation technologies were applied to remove bio-non-degradable,hard dissolving and resistant to microorganisms camphor and the like-oil compounds.The effect was remarkable,and COD remove ratio reached more than 70%.Electrolysis and oxidation were chosen to degrade bio-non-degradable compounds,to improve compatibility of the water with environment and to reduce COD.Afterwards anaerobic and aerobic technologies were applied.
