摘要/Abstract

摘要： 研究了利用二氧化氯直接氧化和催化氧化处理铬黑T模拟废水，单纯用二氧化氯化学氧化处理COD为2928mg/L的铬黑T废水时，最佳pH值为1.8，二氧化氯投加量为1200mg/L，反应60min，COD去除率为24.1%，BOD₅去除率为21.8%，脱色率为70.0%.在最佳pH值为1.8，经过1200mg/L二氧化氯和0.25g TiO₂催化氧化60min后，COD去除率为33.6%，BOD₅去除率为53.2%，脱色率为75.2%.结果表明，铬黑T经化学氧化和催化氧化后，分子中苯环和萘环被氧化分解为羧酸和苯醌，并进一步分解为无机物，为难降解废水的后续处理创造了条件.

Abstract: The direct oxidation and catalytic oxidation of simulated wastewater containing eriochrome black T with chlorine dioxide as an oxidant was studied. The COD, BOD removal efficiency, and decolor efficiency are 24.1%, 21.8%, and 70.0%, respectively, under the condition of wastewater COD 2928mg/L, an optimum pH value of 1.8, a dosage of chlorine dioxide 1200mg/L by reacting for 60min. The COD, BOD removal efficiency and decolor efficiency are 33.6%, 53.2%, and 75.2%, respectively, under the condition of wastewater COD 2928mg/L, the optimum pH value of 1.8, the dosage of chlorine dioxide 1200mg/L, and a dosage of TiO₂ 0.25g by reacting for 60min. The result indicates that the benzene ring and naphthalin ring in the eriochrome black T molecule is degraded to organic acid and benzoquinone, and further becomes inorganic substances by chlorine dioxide direct oxidation and catalytic oxidation, which is good for the further treatment of the refractory bio-degradation wastewater.
