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,BOD_5 350 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。
CSBR technique is introduced for treating printing and dyeing wastewater. When the CODa, BUDs, SS and chroma in effluent water are averagely 1 200 mg/L,350 mg/L,200 rag/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）.
