摘要
以总还原硫(TRS)为考察指标,分析了基于厌氧-混凝-高级氧化工艺的中试系统各处理单元对转运站污水中恶臭物质的处理效果。转运站污水中,TRS总量为0.602 mg/L水,而经过厌氧、混凝、高级氧化等处理单元后依次为4.167,3.513,0.168 mg/L水。厌氧对含硫有机物的降解是恶臭物质产生的重要过程,混凝过程对污水恶臭去除作用很小。相比于混凝出水,高级氧化对恶臭物质去除率在95%以上。
The effect of transfer station waste water odor treatment by each unit was analyzed.The pilot scale system was based on anaerobic-coagulation-advanced oxidation.Total reduced sulfur（TRS） was taken as indexes.The amount of TRS was 0.602 mg/L in transfer station waste water.After treatment by the units of anaerobic-coagulation-advance oxidation,the values turn into 4.167,3.513 and 0.168 mg/L.Anaerobic degradation of sulfur-contained organic compounds was an important process of odor material generation.Coagulation showed little effect on waste water odor removal.Removal rate of odor material by advanced oxidation was over 95 %,comparing to effluent of coagulation.
