摘要
Abstract
An experimental research on advanced treatment of underground coal gasification wastewater by catalytic ozonation was carried out, which happened continuously in a fixed bed reactor loaded with solid catalysts and effects of trace ozone as oxidants on catalytic ozonation were studied. The results showed that when wastewater COD was 300 mg/L or so, the treatment unit' s COD removal increased by 45％ with trace ozone added in, with each mg ozone treating 2. 4 mg organic compounds on average. And it was also found that the optimum ozone dosage for wastewater with COD 200 mg/L was approximately 20 mg ozone per liter wastewater where wastewater inflow was 1 L/h and gas-water ratio was 15 : 1. Meanwhile, experiments showed that wastewater chroma was efficiently removed by catalytic ozonation. Compared with peers experimental research, the technology of catalytic oxidation with trace ozone in advanced wastewater treatment was cost-effective.关键词
