摘要
采用混凝预处理-水解酸化-SBR工艺处理造纸中段废水,确定了水解酸化器、SBR反应器的最佳运行参数。研究结果表明,采用水解酸化-SBR工艺处理混凝后的造纸中段废水,在进水CODcr值为1500mg/L的情况下,出水完全达到GB3544-2001所规定的排放要求并且能循环回用。
Hydrolysis acidification -SBR process was conductcd to treat the effluent from Washing , Scrccning , Bleaching plants by flocculation and the running parameters were decided of the anaerobic reactor and the SBR,, The results showed that the effluent with 1500mg/L CODcr could be purified to meet the requirement of national standard of GB3544 -2001 and be recycled by using the hydrolysis acidification - SBR, process.
