摘要:
针对牛仔衣染色(以靛蓝染料为主)废水色度较高、有毒性及污染严重的特点,确定采用水解酸化/生物接触氧化/沉淀的工艺处理该废水。在丽发制衣厂的应用实践表明:该工艺切实可行,运行费用低,处理效果稳定,出水水质达到DB 44/26—2001中一级排放标准,COD、BOD5、SS、色度去除率分别达到94%、92%、87%、83%。

Abstract:
The wastewater fromjeans production(mainly containing indigo dyeing) is characterized by higher colourity, toxicity and severe pollutant. With the consideration of these special characters, the wastewater is treated by hydrolysis acidification /biological contact oxidation /sedimentation process. The operation in Lifa Clothing Manufacture demonstrates that this process is feasible. Its running cost is low and the treatment results are stable. Finally, it also shows that the treated effluent quality accords with the requirement of Ⅰclass standard of water pollutant discharge extreme(DB 44 /26—2001) in Guangdong province. Its COD, BOD5, SS and colourity removal rate reach 94%, 92%, 87% and 83% respectively.
