摘要
对保险粉生产中富含有机物的高COD_(Cr)的废水进行了处理实验并应用于生产。通过实验研究,利用氯碱生产的废水——氯水为光催化氧化的氧化剂,对废水的COD去除率达80%以上,经生化处理。实际生产表明,处理后废水COD_(Cr)<150mg/L,实现达标排放。该法以废治废,实现了低成本处理保险粉生产废水。
Treatment of organic rich sodium hydrosulfite wastewater with high COD_(Cr) was studied and the method was applied in the production. The results indicated that the COD_(Cr) of sodium hydrosulfite wastewater could be reduced over 80 percent by photic-catalytic oxidation-biochemistry treatment with wastewater from the production of chloro-alkali, i.e. chlorine water as oxidant. Actual production shows that the COD_(Cr) of wastewater after treatment is less than 150 mg/L and meets the requirements of discharge. Wastewater is treated by waste chlorine water, which costs low in the treatment of sodium hydrosulphite.
