摘要
以2,4-二氯酚（2,4-DCP）去除率和柱中pH、溶解氧（DO）质量浓度变化，考察释氧．好氧生物反应柱降解2，4-DCP实验的运行效果。结果表明，出水2，4-DCP质量浓度为0．9～2μg／L，去除率达98％；反应层pH范围为8．35-9．4，DO质量浓度平均为7．1mg／L，满足微生物生长要求；释氧层稳定后DO质量浓度在8mg／L左右，释氧良好；反应柱最终出水pH符合地表水环境质量标准。
To study the treatment efficiency of oxygen releasing-aerobic biological reactive column in 2,4-dichlorophenol （2,4-DCP） contaminated water, the removal rate of 2,4-DCP and the change ofpH and DO concentration were studied in the experiment. The results showed that 2,4-DCP concentration of the effluent was 0.9～2μg/L and the removal rate was 98%; pH range of reactive layer was 8.35 - 9.4 and DO mean concentration was 7.1 mg/L, these could meet the requirements of microbial growth; the stable DO concentration of the oxygen releasing layer was about 8 mg/L; pH value of the reactive column effluent complied with the standard of surface water qualities in our country.
