强化反硝化脱氮湿地外加碳源研究进展

Development on Carbon Source Addition of Enhanced Denitrification Constructed Wetland

人工湿地作为一种新型污水处理技术已被广泛应用,碳源是影响其反硝化脱氮的主要因素之一,针对污水中C/N比较低的问题,需向系统中额外投加碳源。在大量相关文献研究基础上,对强化反硝化脱氮人工湿地的外加碳源进行了总结,并比较了外加碳源的种类和及其优缺点。并对人工湿地外加碳源的研究进行了讨论和展望,为今后强化脱氮人工湿地外加碳源的深入研究提供了建议。

The constructed wetland had been widely used as a new type wastewater treatment technology, and the carbon source was one of the main factors influencing its denitrification. The carbon source was needed to adding in the constructed wetland to solve the low C/N ratio problem of wastewater. Based on a large number of literature review, the external carbon sources of enhanced denitrification constructed wetlands were summarized, and the types of carbon source and their advantages and disadvantages were compared. The research on carbon source addition of constructed wetland were also discussed and prospected, and suggestion was provided for the further study of carbon source addition in enhanced denitrification constructed wetland.
