酸洗废液在Fenton氧化深度处理造纸废水中的应用

摘要

以公司二级生化后的造纸废水为研究对象，首先确定了其Fenton氧化的最佳实验条件和在该实验条件下的Fenton氧化处理效果，然后分别将钛白粉废酸和钢铁废酸用于Fenton氧化，确定其最佳的Fenton氧化条件，最后以不同的混合比将钛白粉废酸和钢铁废酸混合用于Fenton氧化，确定其最佳的混合比。对比不同条件下Fenton氧化的处理效果和处理成本，选择Fenton氧化的最佳工艺条件。%The optimal process conditions and the Fenton oxidation treating effect were determined taken the eflfuent after the second stage biochemical treatment in our company as an object. Furthermore, titanium dioxide waste acid and steel waste acid were used to Fenton oxidation to ifnd the optimal conditions in Fenton oxidation process. The mixing liquor of the two pickling waste liquor at different ratios was used for the Fenton oxidation to conifrm the optimal ratio. The optimal conditions for Fenton oxidation were selected with comparison of treating effect and the cost at different conditions of Fenton oxidation.
