摘要
为有效降解水中污染物,保护水生态环境.本文以某污泥为原料制备生物炭并用于活化PDS降解水中的有机污染物,Fe-MSDBC吸附量为324.4 mg/g,且在90 min内能够降解86.1％的TC,吸附性和催化性能得到提升;并以NaOH作为再生方法,经过3次循环后,TC的降解率由原来的8.4％提升为35.8％;且在实际应用中,经过处理的二沉、三级处理出水的COD符合环保排放标准,且对TP的处理效果也很好.
Abstract
To effectively degrade pollutants in water and protect the aquatic ecological environment.this article uses a certain sludge as raw material to prepare biochar and uses it to activate PDS to degrade organic pollutants in water.The Fe-MSDBC adsorption capacity is 324.4 mg/g,and 86.1％of TC can be degraded within 90 minutes.The adsorption and catalytic performance are improved.Using NaOH as the regeneration method,after 3 cycles,the degradation rate of TC increased from 8.4％to 35.8％.In practical applications,the COD of the treated secondary and tertiary effluent meets environmental discharge standards,and the treatment effect on TP is also good.
