The emergent plants may differ in their capacity to assimilate nutrients from eutrophic water bodies, so the utilization of suitable emergent plants is the key part for successful restoration of shallow eutrophic lakes and rivers. This research applied the depletion method to study the kinetics of uptake of nutrient (H2PO4−, NH4+, NO3−) in different nutrient stresses by the five emergent aquatic plants (Acorus calamus L., Typha orientalis, Lythrum salicaria L., Sagittaria trifolia L., Alisma plantago-aquatica Linn) in the riverine zones of Dashi River (39°30′–39°40′ N, 115°59′–116°5′ E), a shallow eutrophic river located in Fangshan District, Beijing. The results showed that at the three phosphorus levels, A. calamus and A. plantago-aquatica had the highest maximum uptake rate values for NH4+ under low to moderate phosphorus conditions, and high phosphorus, respectively. T. orientalis had the highest maximum uptake rate values for NO3− at all phosphorus concentrations, while the Michaelis-Menten constant values of L. salicaria and A. plantago-aquatica were smaller. At the three nitrogen levels, the maximum uptake rate values for H2PO4− were the greatest for A. plantago-aquatica at the low to moderate nitrogen levels and L. salicaria at high levels. Meanwhile, T. orientalis and L. salicaria had the smallest Michaelis-Menten constant values. In this study, nitrogen microbial transformations, such as nitrification, denitrification and their coupling were not measured and their role in measuring kinetics was not assessed. Thus, achieved results shall be considered as a synthesis of several processes mediated by plants, a theoretical guidance to the selection of plant species for phytoremediation of polluted water bodies with different nutrient stresses for quality improvement around the diverse rivers in Haihe River basin.

Từ thực trạng chất lượng nước thải sau biogas tại các trang trại chăn nuôi lợn, nghiên cứu đã lựa chọn hai loài thực vật thủy sinh để xử lý nước thải theo định hướng nghiên cứu ứng dụng công nghệ bãi lọc trồng cây nhân tạo. Thí nghiệm được thiết kế nhằm đánh giá khả năng chống chịu COD, NH4+ và pH của Thủy trúc (Cyperus alternifolius) và Cỏ nến (Typha orientalis) thông qua khả năng sinh trưởng ở các nồng độ khác nhau. Cả hai loài thực vật cho sinh khối ổn định trong dải pH từ 5 đến 9, nồng độ COD đến 1000 mg/L và nồng độ NH4+ từ 50 đến 250 mg/L. Hiệu suất xử lý TSS (Total Suspended Solids – Tổng chất rắn lơ lửng), COD (Chemical Oxygen Demand – Nhu cầu oxy hóa học), NH4+, T-N (Total Nitrogen – Tổng nitơ) của Thủy trúc tương ứng là 85,9%, 76,8%, 76,8%, 66,8% và Cỏ nến là 85,4%, 66,5%, 61,5%, 52,0%. Chất lượng nước thải sau xử lý đều đạt quy chuẩn cho phép đối với nước thải chăn nuôi (QCVN62-MT:2016/BTNMT, cột B). Tuy nhiên, Thủy trúc có ưu thế hơn nhờ khả năng chống chịu tối ưu, hiệu quả xử lý và thời gian xử lý các chất ô nhiễm của loài thực vật này.

A hydroponic system was used to evaluate atrazine (ATZ) removal and uptake by three emergent hydrophytes, Iris pseudacorus, Lythrum salicaria and Acorus calamus, determining their potential as phytoremediation agents for ATZ-contaminated water. After 20 days of exposure, the relative growth rate of plants in sterile conditions was less than in natural conditions. ATZ amount in a culture solution planted with emergent plants decreased significantly compared with an unplanted solution, and the removal rate of ATZ in natural conditions was greater than in sterile conditions (p < 0.05). The degradation contributions of I. pseudacorus, L. salicaria and A. calamus were 75.6, 65.5 and 61.8%, respectively. Those of the corresponding microbial population in the solution were 5.4, 11.4 and 17.4%, respectively. Emergent plants play a dominant role in reducing the ATZ level in the water body and could be used as phytoremediation agents.

Due to manganese mining and slag accumulation, the geological structure of the wetland polluted by heavy metals in Xiangtan Manganese Mine area was seriously damaged, hence biodiversity loss, severe soil, and water pollution, as well as serious heavy metal pollution to food, vegetables, and other natural sources. In order to restore the ecological environment of the mining area, in 2015, the ecological restoration test of heavy metal polluted wetlands in the mining area was carried out. The results showed that the Mn content of different parts of Koelreuteria paniculata root from high to low order: fine root > small root > medium root > large root. The Mn content of different parts of Elaeocarpus decipiens root from high to low order: large root > medium root > small root > fine root. The order of Mn content in plants of the wetland restoration from high to low is as follows: Canna warscewiezii > Thalia dealbata > Boehmeria > Pontederia cordata > Typha orientalis > Nerium oleander > Softstem bulrush > Iris germanica > Acorus calamus > Arundo donax > Phragmites australis; The order of Internal Cu content from high to low is as follows: Acorus calamus > Thalia dealbata > Softstem bulrush > Canna warscewiezii > Typha orientalis > Arundo donax > Boehmeria > Iris germanica > Pontederia cordata > Nerium oleander > Phragmites australis; Zn content from high to low order is as follows: Canna warscewiezii > Acorus calamus > Thalia dealbata > Typha orientalis > Pontederia cordata > Arundo donax > Softstem bulrush > Iris germanica > Boehmeria > Phragmites australis > Nerium oleander; Cd content from high to low order is as follows: Phragmites australis > Softstem bulrush > Thalia dealbata > Nerium oleander > Boehmeria > Canna warscewiezii > Acorus calamus > Iris germanica > Typha orientalis > Pontederia cordata > Arundo donax. The results of this study have provided a theoretical basis and decision-making reference for the evaluation of heavy metals polluted wetland restoration, protection, and reconstruction effects and the selection of ecological restoration modes.
