摘要
在生物厌氧工艺处理难降解造纸中段废水之后,采用了60Coγ射线深度氧化处理厌氧出水,研究了不同条件下辐射剂量对COD的影响.结果表明,随着辐射剂量的增加,COD的去除率呈上升趋势;且在氧气氛下,剂量为1 kGy辐照对废水COD的去除率即达37%.另外,还研究了辐射联合纳米TiO2技术对造纸废水COD的影响.
This paper discussed the papermaking wastewater after the ABR(anaerobic baffled reactor) anaerobic biological treatment,using the 60Coγ-ray irradiation technology dealt with the anaerobic water,studied under different conditions of irradiation on the COD.The results show that with increasing radiation dose,COD removal rate can rise;and in O2 atmosphere,it can be up to 37 % for COD removal rate under 1 kGy irradiation dose.This article also exploreed the joint irradiation treatment of papermaking wastewater with nano-TiO2.
