Periphyton widely exists in natural water bodies, with the characteristics of huge biomass generation, strong ecological function, and sensitive response to water quality. It removes the pollutants in water bodies mainly through the processes of absorption, metabolism, adsorption, and complexation, etc. Owing to its high tolerance against pollution and high removal efficiency for nitrogen and phosphorus, as well as the feasibility of recycling its cells at low cost, periphyton is a promising candidate for developing the treatment techniques of water purification. The newly-developed artificial periphyton systems, e.g., algal turf scrubbers, periphyton biofilm systems, periphyton aquaculture systems, have been successfully applied in treating livestock manure, aquaculture wastewater, and municipal sewage. However, further researches are needed to understand the growth patterns of periphyton, its physiological responses to pollutants concentration, and its molecular biological mechanisms in removing pollutants.
周丛生物广泛存在于天然水体中，具有生物量生成巨大、生态功能强大以及对水质反应敏感等特点。它主要通过吸收、代谢、吸附和络合等过程去除水体中的污染物。由于其对污染具有高耐受性、对氮和磷具有高去除效率，以及低成本回收其细胞的可行性，周丛生物是开发水净化处理技术的一个有前途的候选者。新开发的人工周丛生物系统，如藻类草皮净化器、周丛生物膜系统、周丛生物养殖系统，已成功应用于处理畜禽粪便、水产养殖废水和城市污水。然而，需要进一步研究以了解周丛生物的生长模式、其对污染物浓度的生理反应以及其去除污染物的分子生物学机制。
