中文摘要:

考察了活性炭和炭化硅两种材料的吸波能力和微波辅助氧化处理p-硝基酚(PNP)溶液的情况.对活性炭固定床而言,1618mg·L^-1 PNP溶液的微波去除率和矿化率分别为96%和91%,而炭化硅固定床上的去除率和矿化率则最高为73%和24%.3种高浓度(3540、6858mg·L^-1和11095mg·L^-1)PNP溶液在活性炭固定床上的微波降解率均大于98%,矿化率均高于96%.活性炭和炭化硅微波辅助氧化降解PNP的中间产物同为o-硝基酚、苯酚和苯醌.活性炭固定床微波降解PNP溶液后出水的可生化性得到明显提高.

英文摘要:

Microwave-absorbing ability of granular activated carbon (GAC) and silicon carbide (SiC), and microwave-assisted oxidation of p-nitrophenol (PNP) through the fixed beds of GAC and SiC were investigated. The removal efficiency of PNP with initial solution concentration of 1618 mg·L^-1 reached 96% and 91% of PNP was mineralized onto GAC fixed bed by microwave irradiation, while the highest removal and mineralization efficiency values of PNP were 73% and 24% respectively onto SiC fixed bed for the same PNP solution. Three high concentration PNP solutions (2540, 6858 mg·L^-1 and 11095 mg·L^-1) were treated by microwave respectively through GAC fixed bed and the removal efficiency values of PNP were all higher than 98% and more than 96% PNP was mineralized. The same intermediate products such as o nitrophenol, phenol and benzoquinone occurred for SiC and GAC during the reaction process, which were degraded further. Biodegradability of the outflow was improved apparently after the treatment by microwave through GAC fixed bed.
