| 摘 要： | 通过中和-气浮-水解酸化-接触氧化工艺对松脂加工废水进行处理,废水的CODCr由2 368 mg/L降至93 mg/L,去除率达到95%以上,其余指标均达到污水一级排放标准.试验结果表明,采用厌氧折流板反应器(ABR)能够很好地控制废水水解酸化的进程;接触氧化段较高的溶解氧对难降解的松脂加工废水有较好的处理效果.

| Abstract: | The process of neutralization-air flotation-hydrolytic acidification-contact oxidation is used in the treatment of the wastewater generated from rosin production.The experiment result shows that the chemical oxygen demand(COD) is reduced from 2 368 mg/L to 93 mg/L,with the COD removal rate of more than 95%.The effluent water completely meets the First Grade Discharge Standard.Meanwhile,the result also indicates that the anaerobic baffled reactor(ABR) is capable of controlling the process of hydrolytic acidification.Therefore,maintaining highly dissolved oxygen in the contact oxidation reactor has a high efficiency for the treatment of rosin processing effluent. |
