人工湿地反硝化外加固体碳源选择研究
A Review of Carbon Source Supplement for Denitrification by Constructed Wetlands
摘要
Abstract
In this paper,with the aims at screening suitable solid carbon sources,corn straw and residual sludge was selected to study the release patterns of carbon sources and relevant pretreatment experiments,and their feasibility of being carbon sources was also discussed from the aspects of release quantity,release rate and release ratio of carbon to nitrogen.The results showed that after alkali pretreatment,the average release amount of carbon element from the corn straw was 10.31 mg/(g · d),0.91 mg/(g · d)higher than that after alkali and acid pretreatment.However,the average release amount of nitrogen after the two pretreatment modes was the same as 0.20 mg/(g · d).The average amount of carbon and nitrogen elements released from the pre-processed sludge was 8.98 mg/(g · d) and 0.21 mg/(g · d) respectively.It was considered that sludge could be used as carbon source for denitrification and therefore resource recovery,reduction and harmless treatment of sludge could be realized.As a result,alkali pretreated corn straw and residual sludge could be used as carbon source supplement for artificial wetlands.关键词
