【摘要】：吡啶是焦化廢水中較為典型的含氮雜環(huán)化合物,難以被生物降解。通過研究吡啶的缺氧生物降解特性,并對其降解產(chǎn)物進行鑒定,以期為實際生產(chǎn)提供理論依據(jù)和為今后進一步研究做出鋪墊。結(jié)果表明,吡啶在本實驗條件下的最佳降解濃度為80 mg·L~(-1),對于后期測定降解中間產(chǎn)物,該濃度和其降解周期均較為合適;戊二醛為吡啶在缺氧反硝化降解過程中的一個重要中間產(chǎn)物,其濃度在反應(yīng)進行32 h時積累達到最大值。在上述實驗基礎(chǔ)上,在底物中加入40 mg·L~(-1)苯酚,其對吡啶的降解產(chǎn)生抑制作用,戊二醛濃度最大值出現(xiàn)在反應(yīng)進行40 h處,由此推斷苯酚對吡啶降解的抑制作用可能產(chǎn)生于吡啶開環(huán)脫氮階段。
[Abstract]:Pyridine is a typical nitrogen-containing heterocyclic compound in coking wastewater, which is difficult to biodegrade.The characteristics of anoxic biodegradation of pyridine were studied and its degradation products were identified in order to provide theoretical basis for practical production and pave the way for further research.The results showed that the optimum degradation concentration of pyridine was 80 mg / L ~ (-1), which was suitable for the later determination of the intermediate product.Glutaraldehyde is an important intermediate product of pyridine in the process of anoxic denitrification and the concentration of glutaraldehyde accumulates to a maximum at 32 h.On the basis of the above experiments, the degradation of pyridine was inhibited by adding 40 mg / L of phenol to the substrate, and the maximum concentration of glutaraldehyde appeared at the reaction time of 40 h.It is concluded that the inhibition of phenol on the degradation of pyridine may occur at the stage of denitrification of pyridine.
