Abstract:
The actual effect of Fe-Cu method on the treatment of dyeing and printing wastewater has been stuided. The reaction mechanism of this method has been discussed. Aiming at the adjustive tank wastewater, tests have been carried on. The results showthat when the wastewater is alkaline, the adding of Cu can improve the reaction speed obviously. The way of anaerobic operation can improve the removal rate of chroma and increase the biodegradation. It is important to mix Cu with Fe. Biochemical treatment takes place sequently after Fe-Cu pretreatment. The organism in the effluent water is 296 mg/Land its chroma is 150 times, and its pH is neutral.
Key words:

摘要：
为研究Fe-Cu法预处理印染废水的实际效果，并深入探讨Fe-Cu双金属法的反应机理，以印染厂调节池废水为研究对象进行了试验研究。试验结果表明，当印染废水为碱性时，铜片的加入能明显提高反应的速率，厌氧运行方式对色度去除率和可生化性提高更具优势；Fe-Cu法预处理再经后继生化处理后，出水COD和色度分别为296mg/L、150倍，出水pH呈中性。
