水洗羽绒废水处理工程的设计

摘要

采用气浮、水解酸化及生物接触氧化相结合的工艺处理水洗羽绒废水，处理规模2000m3/d，工程设计考虑了对羽绒的回收，生物处理后的废水经过滤后回用于水洗羽绒工艺的前段，投入运行后效果良好。%Using a combination of flotation, hydrolysis acidi-fication and biological contact oxidation process to process fe-ather washed down wastewater, the size is 2000 m3/d, the eng-ineering design considering the recovery of the feather, and the biological treatment of wastewater filtered back for the prec-eding paragraph of washing down process, put ing into effect is good after operation.
