摘要
梳理了几种常见的农业废弃物制备外加碳源的基本方法,总结了不同类型农业废弃物有效碳源的含量、强化脱氮的效果以及释放二次污染的风险,分析了预处理方法影响农业废弃物释碳的主要因素,如发酵温度、投放方式、浸泡时间和制备工艺;最后针对传统农业废弃物制备的外加碳源释碳量不可控、启动较慢、自身释放氮素等问题,提出了以农业废弃物制备发酵液或者缓释碳源基质的研究方向,以期为生物质碳源在强化尾水脱氮领域的应用提供参考。
Several common basic methods for preparing additional carbon sources from agricultural wastes are summarized,the content of effective carbon sources,the effect of enhanced denitrification and the risk of releasing secondary pollution of different types of agricultural wastes are summarized,and the effects of pretreatment methods are analyzed.The main factors of carbon release from agricultural waste,such as fermentation temperature,feeding method,soaking time and preparation process;finally,for the problems of uncontrollable carbon release from external carbon sources prepared from traditional agricultural waste,slow startup,and self-release of nitrogen,etc.The research direction of preparing fermentation broth or slow-release carbon source substrate from agricultural waste was proposed,in order to provide reference for the application of biomass carbon source in the field of enhanced tailwater denitrification.
