两级混凝/水解酸化/好氧生物处理纺织工业园区废水研究

Study on Treatment of Textile Industry Park Wastewater by Two Phase Coagulation/Sedimentation/Hydrolytic Acidification/Aerobic Biology

介绍了某纺织工业园区废水集中处理的工程实例,采用两级混凝/水解酸化/好氧生物处理工艺对废水进行处理.在进水CODCr=1 000 mg/L、BOD=250 mg/L、SS=300 mg/L、色度=500倍和pH=11的条件下,CODCr、BOD、SS和色度的去除率分别达到96%、96%、92%和96%.出水CODCr、BOD、SS和色度各项指标值均达到一级排放标准要求.

A case of textile industry park wastewater project is introduced.Wastewater is treated by two phase coagulation-sedimentation-hydrolytic acidification-aerobic biology.The influent wastewater quality is CODCr=1000mg/L,BOD=250 mg/L,SS=300 mg/L,Chroma=500 and pH=11.96%、96%、92% and 96% removal rate of CODCr,BOD,SS and Chroma is reached,respectively.The value of CODCr、BOD、SS and Chroma of treated wastewater is up to the first level.
