摘要
根据浙江某针织印染有限公司排放废水的水质,确定采用废水分类预处理-水解酸化-二段生物接触氧化-物化处理工艺。实践表明,该废水处理工程设计完工运行后,出水完全达到GB 4287—2012《纺织染整工业水污染物排放标准》的要求,且系统运行稳定,运行费用较低。
According to wastewater quality from a knitted dyehouse in Zhejiang province, a process of sewage classification and pretreatment→hydrolysis acidification→two-stage biological contact oxidation→physicochemical treatment is set up. The practice shows that, the effluents after treatment can fully meet the standard of GB 4287—2012＂Discharge standard of water pollutants for dyeing and finishing of textile industry＂. The system is running stably with low cost.
