植物碳源的养分释放及其对人工湿地水体氮素的影响数据集
A dataset of nutrient release from plant carbon sources and its effects on nitrogen dynamics in constructed wetlands
摘要
Abstract
Adding external carbon source is the most effective method to achieve complete denitrification in constructed wetlands.However,traditional carbon sources are often costly and involve complicated processing.In this study,commonly-found wetland plants(Typha orientalis,Canna indica,Nelumbo nucifera,Potamogeton crispus,Miscanthus lutarioriparius,Carex brevicuspis)and agricultural residues(corn cobs and rice straw)were selected as carbon source materials,which conforms to the waste utilization principle of"local sourcing and in-situ treatment".The release capacity data of 8 different plant carbon source nutrients(organic carbon,total nitrogen)were observed through the plant carbon source release test,and the plant materials with better carbon release capacity and weak nitrogen release capacity were comprehensively screened out for denitrification test observation in constructed wetlands.This dataset collates the following two parts:(1)experimental datasets of different plant carbon sources,including organic carbon concentration and total nitrogen concentration released by 8 plant carbon sources over time;and(2)denitrification test dataset of constructed wetlands with different plant carbon sources,mainly including the effects of three plant carbon sources on total nitrogen concentration,organic carbon concentration,ammonium nitrogen concentration,nitrate nitrogen concentration,etc.The data and findings were reviewed by experts and validated for reliability.A research paper based on this dataset has been published.This dataset provides a reference for the study and utilization of wetland plant carbon release dynamics,and offers data support for enhancing nitrogen removal efficiency in constructed wetlands.关键词
