水解酸化-生物接触氧化-漂白脱色工艺处理纺织综合废水

TREATMENT OF TEXTILE COMPREHENSIVE WASTEWATER BY HYDROLYTIC ACIDIFICATION-BIOLOGICAL CONTACT OXIDIZATION-BLEACHING AND DECOLORATION PROCESS

溢达纺织有限公司纺织综合废水水质为 :pH 10～ 14、CODCr10 0 0～ 15 0 0mg L、BOD530 0～ 4 5 0mg L、SS 30 0mg L、S2 - 3mg L ,水温 4 0～ 5 0℃、色度 4 0 0～ 6 0 0倍 ,采用水解酸化 生物接触氧化 漂白氧化脱色处理工艺 ,处理后出水达到排放目标。经过 2a多时间的运行实践 ,结果表明 ,处理的出水水质稳定。

The conditions of the textile comprehensive wastewater discharged by Yida Textile Limited Company are as below:pH 10～14,COD Cr 1 000 ～ 1 500 (mg/L),BOD 5 300～450 (mg/L),SS 300 (mg/L),S 2- 3 (mg/L),wastewater temperature between 40 and 50℃ and its colority ranging from 400 to 600 times.The effuent is controlled within the discharging standards by using hydrolytic acidification-biological contact oxidization-bleaching and decoloration process.After operation for more than two years,the operational result has shown that the effluent quality keeps stable.
