摘要：

采用CSBR工艺处理印染废水，在平均进水水质COD_Cr,为1 200 mg/L，BOD₅ 350 mg/L，SS 200 mg/L，色度400倍时,其去除率分别为90%、94%、91%和85%，出水可达到国家《纺织染整工业水污染物排放标准》（GB 4287—1992）二级排放标准。

Abstract:

CSBR technique is introduced for treating printing and dyeing wastewater.When the COD_Cr,BOD₅,SS and chroma in effluent water are averagely 1 200 mg/L,350 mg/L,200 mg/L,400 times,respectively,the operation results indicate that the removal efficiencies are 90%,94%,91% and 85%,respectively.The results also show that the water quality of the effluent can meet the requirements of the Second Grade of Water Pollutants Discharge Standard of Textile,Trinting and Dyeing Industry(GB 4287-1992).

Key words: printing and dyeing wastewater , continuous flow constant level sequencing batch reactor , biological treatment
