| Abstract: | The feasibility of treating secondary biological paper mill effluent by ionizing radiation was studied experimentally. The results showed that COD of wastewater mainly consists of 69.5% of organic compounds (1000<Mr<3000) and 6.9% of organic compounds (Mr>3000). DOC of wastewater mainly consists of 40.6% of organic compounds (1000<Mr<3000) and 31.6% of organic compounds (Mr>3000). Ionizing radiation may enhance transformation from the high molecular organic compounds (1000<Mr<3000) to low molecular organic compounds (Mr<1000), resulting in gradual decrease of COD of organic compounds (1000<Mr<3000) and increase of COD of organic compounds (Mr<1000). In addition, coagulation can remove organic compounds (Mr>3000) effectively with the removal rate 60%, and reduce the absorbance significantly. With radiation doses increasing, the BOD5 concentration of secondary effluent increased, indicating the enhancement of biodegradability. Compared with pre-treatment of the paper mill effluent, the combined process of coagulation and ionizing radiation possesses was more suitable for the advanced treatment of paper mill effluent. |
| Keywords: | paper mill effluent coagulation ionizing radiation advanced treatment relative molecular mass distribution |
