在可见光照射的条件下,利用光催化技术与微生物法耦合来处理空气中的VOCs。结果表明,光催化剂与微生物耦合装置对二甲苯浓度的去除率会随着其浓度提高而降低,细菌驯化后其去除率又逐步上升。最后在进气浓度为800mg/m~3时,去除率稳定在80%左右。
The VOCs was treated by coupling of visible-light-driven photocatalysis and bio-degradation under visible light irradiation. The results showed that the degradation rate of xylene treat by coupling of visible-light-driven photocatalysis and biodegradation reduced with the increased of concentration. After bacteria domestication,the degradation inceased again. Finally,the degradation rate steady at aroud 80% under xylene intake concentration of 800 mg/m~3.
