Improved biodegradability of pyridine by means of photocatalysis

YAN Rong,WANG Jie-wei,ZHANG Yong-ming(College of Life and Environment Sciences,Shanghai Normal University,Shanghai 200234,China)  
Pyridine,one of bio-recalcitrant compounds,was treated with photocatalysis to break its molecular structure.It could not be oxidized by potassium dichromate until photocatalysis,which was proved by COD increasing with photocatalytic time increasing.Pyridine was taken as organic carbon source to reduce nitrate in denitrification,and experimental results indicated that nitrate removal percentage with photocatalysis was increased as 4.2 times as that without photocatalysis.When pyridine was treated with photocatalysis and used as organic carbon source for denitrification of 30 min,the nitrate removal percentage was equivalent to the same effect by adding 150 mg/L of glucose as carbon source,which suggested that biodegradability of pyridine was improved after photocatalysis,which could realize pyridine and nitrate removal at the same time.
