生态沟是一种经济高效、广泛应用于农业面源污染治理的方法,主要由植物、基质和排水沟构成.本研究重点分析了水生植物、微生物、基质、水体流速和水位等环境因子对生态沟净化效果的影响,并梳理了国内外生态沟的改良技术及组合工艺.结果表明,经过结构改良的二级生态沟和沸石屏障生态沟显著提高了总磷、总悬浮物和氨氮的去除效果;几种生态沟的组合工艺能够增强对污水的净化能力,优化生态景观,并且能将碳转化为有机物积累在基质或者生物体内,具有碳汇效应,有助于实现双碳目标.研究结论可为生态沟与其他工艺组合、应用范围的拓展以及工程实践提供参考依据.
Analysis on the purification effect of ecological ditch improvement technology and combination process
Ecological ditch is a cost-effective and widely used method for agricultural surface pollution,which mainly consists of plants,substrate and drainage ditch.This study mainly analyzes the effects of environmental factors such as aquatic plants,microorganisms,substrate,velocity of flow and water level,etc.The documents of ecological ditch at home and abroad were analyzed.It was found that the structurally improved secondary eco-ditch and zeolite barrier eco-ditch effectively improved the removal effect of total phosphorus,total suspended solids and ammonia nitrogen;And the combined process of eco-ditch enhanced the purification ability of eco-ditch for composite pollutants,optimize the ecological landscape at the same time.And it can convert carbon into organic matter and accumulate in the substrate or organisms,which has carbon sink effect and contribute to the realization of the dual carbon goals.The results of the study can provide reference for the application scope,and engineering practice of ecological ditches and other processes.
