“…( 2) From the variation of DO content in the plant, it can be deduced that with the abundance of algae species, the amount of DO produced by algae photosynthesis is also increasing, which accelerates the nitrification rate in plants. (3) The root system of aquatic plants not only has the function of radial oxygen secretion but also can produce nutrients to promote the reproductive growth of the microbial layer around the root system, thus ensuring the effective removal of TP (Nash et al 2020, Shi et al 2020. Besides, Biological unit I required regular cleaning due to algae build-up.…”

Paddy field drainage discharged directly into natural waters without the treatment will aggravate water eutrophication. The removal characteristics of the purified paddy field drainage was explored by establishing an experimental device that simulates a compound ecological ditch (CED), which significantly optimized the absorption capacity of nutrients in rice fields. The results show that the changes of pollutants before and after the experiment indicates that the CED has a significant effect on the removal of pollutants in the drainage of the paddy field. The degradation trend of pollutants in 5 rice growth cycles is in agreement with the first-order kinetic degradation model. Bio-phase microscopy and microbial diversity index reveal that the species of bacteria and plankton algae increase in the continuous operation of the CED, accompanied by the emergence of higher micro-animals. It shows that improved ecosystem water quality is more suitable for the survival and reproduction of various microorganisms. The research results provided a new idea for further improving paddy field drainage treatment efficiency.

“…Aquatic plants are the main producers in aquatic ecosystems and are critical for the management of the water environment. Plant remediation is an economical and aesthetic solution to many global environmental problems, and to the use of plants to remove and accumulate pollutants in the environment, which involves using plants to mitigate, transfer, stabilize, or degrade pollutants in soil, sediment, and water (Lu et al 2018;Nash et al 2020). Aquatic plants not only provide habitats for various aquatic animals but also enhance the biodiversity and stability of aquatic ecosystems (Zhou et al 2018a).…”

This study focused on the water quality of a river in Wuhan City, China, that is surrounded by ponds that were transformed into a bypass multipond wetland system to improve river water quality. The bypass multipond wetland system included surface flow artificial wetlands, modified partition ponds, aeration reoxygenation ponds, ecological ponds, and other processes. After the stable operation of the process, the water transparency was higher than 60 cm and the dissolved oxygen (DO) was higher than 5 mg/L, while the ammonia nitrogen (NH3-N) concentration was less than 1.0 mg/L, total phosphorus (TP) was lower than 0.2 mg/L, and chemical oxygen demand (COD) was lower than 20 mg/L, achieving the treatment target. After monitoring the results of each process, the process which best enhanced the water transparency enhancement was the surface flow of the artificial wetlands and ecological ponds. The aeration reoxygenation pond had the best effect on DO enhancement. The processes that most affected NH3-N and TP removal were the surface flow artificial wetlands and ecological ponds. The modified parthenogenic pond had the greatest effect on COD removal. The bypass multi-pond wetland system not only improved the river water quality but also enhanced the river landscape, and can act as a reference for similar river water quality improvement actions.

“…The physical characteristics of SG fiber are almost similar to those of coconut coir, abaca, pineapple, and other natural fibers possessed a sound absorption capability. The potential of SG growth considered as one of the promising methods to reduce water pollution has been explored to ensure the effectiveness of phytoremediation for the treatment of sago mill effluent [ 18 ].…”
