Industrialization and overpopulation have polluted aquatic environments with significant impacts on human health and wildlife. The main pollutants in urban sewage are nitrogen, phosphorus, heavy metals and organic pollutants, which need to be treated with sewage, and the use of aquatic plants to purify wastewater has high efficiency and low cost. However, the effectiveness and efficiency of phytoremediation are also affected by temperature, pH, microorganisms and other factors. The use of biochar can reduce the cost of wastewater purification, and the combination of biochar and nanotechnology can improve the efficiency of wastewater purification. Some aquatic plants can enrich pollutants in wastewater, so it can be considered to plant these aquatic plants in constructed wetlands to achieve the effect of purifying wastewater. Biochar treatment technology can purify wastewater with high efficiency and low cost, and can be further applied to constructed wetlands. In this paper, the latest research progress of various pollutants in wastewater purification by aquatic plants is reviewed, and the efficient treatment technology of wastewater by biochar is discussed. It provides theoretical basis for phytoremediation of urban sewage pollution in the future.
工业化和人口过剩导致水生环境受到污染，对人类健康和野生动物产生了重大影响。城市污水中的主要污染物是氮、磷、重金属和有机污染物，需要用污水进行处理，利用水生植物净化废水具有高效、低成本的特点。然而，植物修复的效果和效率也受到温度、pH 值、微生物等因素的影响。生物炭的使用可以降低废水净化的成本，生物炭与纳米技术的结合可以提高废水净化的效率。一些水生植物可以富集废水中的污染物，因此可以考虑在人工湿地中种植这些水生植物，以达到净化废水的效果。生物炭处理技术可以高效、低成本地净化废水，并可进一步应用于人工湿地。本文综述了水生植物净化废水中各种污染物的最新研究进展，探讨了生物炭对废水的高效处理技术，为未来城市污水污染的植物修复提供了理论依据。
