Study on butadiene-acrylonitrile latex wastewater treatment by activated carbon-microwave irradiation
活性炭-微波辐照处理丁腈胶乳生产废水的研究

The activated carbon-microwave radiation process was adopted to treat the butadiene-acrylonitrile production wasterwater, and the influences of the category and usage of catalysts, the initial wastewater concentration, the initial pH value of the wastewater, the irradiation time and power of the microwave to the COD removal rate were studied. The results show that the COD removal rate can reach 96.6% when 3 g powder activated carbon is used to treat 100 mL butadiene-acrylonitrile latex production wastewater with the concentration of about 3500 mg/L under the condition of 200 W microwave irradiation power and 4min irradiation time. The dynamics study shows that the reaction process is approximately consistent to the first order reaction dynamics equation under the optimal operation conditions and the dynamic equation can be expressed as ln(C0/C)=0.6034t+0.9247, whereas R=0.9926, the reaction velocity constant k=0.6034 min-1 and the half life t1/2=1.15 min.
