【Abstract】 The quality parameters of the combined wastewater from the textile production of Guangdong Yi-da Textile Co.,Ltd.were:pH=10～14,ρ(COD Cr )=1000～1500mg/L,ρ(BOD 5 )=300～450mg/L,ρ(SS)=300mg/L,ρ(S 2- )=3mg/L,water temperature=40~50℃,and chroma=400~600times.The wastewater was treated by a process of hydrolytic acidification-biological contact oxidation.The results of the operation showed that the quality parameters of the effluent water after the treatment were as follows:pH=7～8,ρ(COD Cr )=89mg/L,ρ(BOD 5 )=20mg/L,ρ(SS)=54mg/L,ρ(S 2- )=0.8mg/L,and chroma=31times,indicating that the quali-ty of the treated wastewater met the discharge standard.更多还原
