摘要:
污水生物处理过程中产生的大量剩余污泥富含植物生长必需的营养物质，为污泥处理湿地这一新型剩余污泥处理技术的开发提供了可能。利用原位静态箱法对3个污泥处理湿地（S1、S2、S3）进行负荷期温室气体排放特征研究，发现在污泥处理湿地系统中CH4、CO2的排放通量表现出明显的季节特征，两者的排放情况均表现为夏季>秋季>春季>冬季的趋势，并且夏季远高于其他季节。污泥处理湿地S2（种植芦苇、通风）和S3(种植芦苇、无通风)的CH4总排放量分别比S1(无芦苇、通风)高出30.5%、15.5%，S1、S2和S3的CH4和CO2总排放量（当量CO2）处在同一量级，全球增温潜能值大致相当。
Abstract:
The large amount of excess sludge generated in sewage treatment process is rich in nutrients necessary for plant growth, which provides a foundation for the development of a new sludge treatment technology, i.e., sludge treatment wetland. In-situ static chamber method was used to investigate the greenhouse gas emission characteristics of three sludge treatment wetlands during the sludge loading period. It was found that CH4 and CO2 emission fluxes showed obvious seasonal characteristics in the sludge treatment wetlands. The CH4 and CO2 emission fluxes showed the trend of summer>autumn>spring>winter, and the emission fluxes in summer were much higher than those in other seasons. The total CH4 emissions of S2 (planted reeds and ventilated) and S3 (planted reeds and unventilated) were 30.5% and 15.5% higher than those of S1 (unplanted and ventilated), respectively. However, the total CH4 and CO2 emissions (CO2-eq) of S1, S2 and S3 were in the same level, and the global warming potentials were roughly equivalent.
