本发明公开了种河涌或水塘的硝化反硝化脱氮自然平流式生态系统及工法，通过水生植物有无的生态工法营造不同环境条件的河涌系统，利用水流运行中通过连续的无水生植物区与水生植物密植区布置单元，以科学模拟A/O工艺实现自然平流式表面流系统，保证水流均匀推流并充分与水生植物和底质接触，形成连续的好氧、缺氧或厌氧部分，达成连续且充分反应的硝化反硝化脱氮过程。本发明功能分区明显、对于氮素去除效果较好，工艺过程易于管理和控制，投资少、运行费用低，且生态工法在保证水质效果的同时兼具增强水环境观赏性功能，可广泛应用于具有定流速的城镇河涌与乡村水塘的面源污染生态处理中。 The invention discloses a natural horizontal flow type ecological system for nitrogen removal by nitrification and denitrification in rivers or ponds as well as an engineering method. River systems with different environment conditions are built with an ecological engineering method based on availability of aquatic plants; continuous aquatic-plant-free area and aquatic plant close planting area arrangement units are used during water flowing, so that a natural horizontal flow type surface flow system is realized by scientifically simulating an A/O (anoxic-oxic) process, uniform plug flow of water currents is guaranteed, the water currents are fully contacted with aquatic plants and substrates, accordingly, continuous oxic, anoxic or anaer
