制革园区污水处理厂调试运行分析

THE COMMISSIONING AND OPERATION OF TANNERY PARK WASTEWATER TREATMENT PLANT

采用水解酸化+CASS工艺处理制革园区工业废水。调试运行结果表明,在进水COD和氨氮平均质量浓度分别为607、50.7 mg.L-1时,出水COD和氨氮平均浓度分别为70、5 mg.L-1,平均去除率分别达88.5%和90.1%。出水水质达到污水综合排放一级标准(GB8 978-1996)。

A hybrid process of acidification-CASS was applied for the treatment of tannery park wastewater.The results showed that the average COD and ammonia nitrogen decreased from 607 mg·L-1 and 50.7 mg·L-1 in raw water to 70 mg·L-1 and 5 mg·L-1 in treated effluent with the average removal rates as high as 88.5% and 90.1%.The effluent quality met the first grade in the national wastewater integrated standard（GB 8978-1996）.
