摘要
对制革生产中的废水分别进行预处理,并回收可利用的产物。使用电化脱色后的废水作为混凝剂进行混凝沉淀。最终,经过气浮、生物接触氧化法处理后,出水水质达标。
The wastewater from leather industry is pretreated respectively, and the available substances are mostly recycled. The wastewater treated by electrochemical discolouration can be used as flocculant to adsorb the pollution. Finally, the wastewater purified through technology of air-floation and bio-contact oxidation method can be allowed to discharge.
