摘要
造纸厂麦草化机浆综合废水经Fe-CA仿酶体系处理后,CODC r去除率非常显著,可达60%以上,木质素大量脱除,有效地提高了废水的可生化性,为难降解废水的后续处理创造了条件。铁与羧酸形成的螯合物(Fe-CA)性能稳定,价格低廉,在功能上能较好地模拟木质素过氧化物酶。研究表明,Fe-CA仿酶体系处理废水的最佳条件为:Fe-CA仿酶用量为10 mg/L废水,原水pH值调至中性,温度30℃,H2O2用量是0.15 g/L,硫酸铝加入量为0.4 g/L,沉降时间6 h。
The CODCr of mixed wastewater from CMP of wheat straw is removed evidently by biomimetic treatment,and the removal of CODCr can reach more than 60%.Bio degradable property of the mixed wastewater is improved through the removal of lignin,and it creates condition for subsequent treatment of poor degradable wastewater.Fe-carboxyl acid complexes have stable characteristics and low price,and can simulate the function of lignin peroxidase very well.The best condition of wastewater treatment is as follows.Fe-CA 10 mg/L wastewater,the pH of original wasterwater is adjusted to neutral,the temperature of wastewater is 30℃,H2O2 0.15 g/L,Al2（SO4）3 0.4 g/L,sedimentation time 6 h.
