猪场废水脱氮与沼气脱硫耦联反应器的运行性能

Reactor Performance Coupling Nitrogen Removal from Wastewater with Hydrogen Sulfide Removal from Biogas

采用鼓泡塔反应器分别在不接种污泥、接种厌氧污泥和接种好氧污泥条件下进行了猪场废水脱氮与沼气脱硫耦联反应器运行性能的研究,结果表明,经过两个月驯化后三个反应器都有良好的氮硫去除效果,NOx--N(硝氮亚硝氮之和)的去除率90%以上,硫化氢的去除率达80%以上,说明废水脱氮与沼气脱硫已经得到了很好耦联。

Bubbling absorption reactor was used in this study coupling nitrogen removal from swine wastewater with hydrogen sulfide removal from biogas. The reactors were performed with seeding of anaerobic sludge, aerobic sludge, or without seeding sludge, respectively. The result showed that after two months of cultivation, all three reactors had the nitrogen removal rate of more than 90%, and the removal rates of hydrogen sulfide were more than 80%. And so the wastewater denitrification and biogas desulfurization had realized very good coupling in a single reactor.
