| 中文摘要: |
| 低污染水类型多样，水体性质复杂，主要包括低污染河水、污水厂尾水、城镇地表径流、农田径流排水（含农村分散性生活污水）4类，具有量大面广、可生化性差、部分水碳氮比（C/N）低等特点。人工湿地是净化低污染水的有效手段，不同类型湿地对低污染水的污染物净化效果不同。本文探讨了不同类型人工湿地净化低污染水中氮的效果，并总结了人工湿地处理低污染水的微生物机制，分析了不同因素（pH、溶解氧、温度、C/N、植物、基质）对人工湿地低污染水水质净化的影响及优化方法，以期为人工湿地净化低污染水的工程实践提供理论参考。 |
| 英文摘要: |
| Low-polluted water mainly includes low-polluted river water, tailwater from sewage plants, urban surface runoff, and agricultural runoff, which have the characteristics of a large discharge volume, wide pollution area, low carbon to nitrogen ratio(C/N), and poor biodegradability. Constructed wetlands are an effective means of purifying low-polluted water. Different types of constructed wetlands have different removal effects on low-polluted water. This paper discusses the nitrogen removal effects in low-polluted water by different types of constructed wetlands. The microbial mechanism of nitrogen removal in low-polluted water is summarized, and the different influencing factors(pH, dissolved oxygen, temperature, C/N, plants, and substances) and optimization methods are analyzed. This study is expected to provide a reference for the treatment and reduction in the pollution load of low-polluted water by constructed wetlands and lake basin protection projects. |
