REDUCTION OF NON-POINT SOURCE POLLUTION IN THE YONG’AN RIVER BY CONSTRUCTED WETLAND BASED ON 9 YEARS

Frontiers of Agricultural Science and Engineering 2023, Volume 10, Issue 4,   Pages 627-638 doi: 10.15302/J-FASE-2023516

Abstract:

The agricultural and livestock activities surrounding the rivers flowing into the lakes have caused non-point source pollution, leading to excessive amounts of nutrient salts in downstream rivers. Introducing river water into constructed wetlands along river course has proven to be an effective solution for decreasing nitrogen (N) and phosphorus (P) loads. This paper reports 9 years of monitoring the Yong’an River and its surrounding constructed wetlands in the upper reaches of Erhai Lake, located in Yunnan Province, China. This study analyzed the main types of pollutants in the river, and evaluated the removal efficiency of pollutants by the constructed wetlands. The findings indicate that total nitrogen (TN) and nitrate nitrogen (NO3–-N) are the primary pollutants in the Yong’an River, which exhibit variation throughout the year corresponding to the alternating wet and dry seasons. Although constructed wetlands are effective in removing NO3–-N and P, their efficacy in removing ammonium nitrogen (NH4+-N) and organic pollutants is limited. This limitation can be attributed to the lack of timely disposal of aquatic plant residues. This research contributes to the understanding of the potential issues that may arise during the extended use of constructed wetlands and provides solutions to address them.

Frontiers in Energy 2018, Volume 12, Issue 2,   Pages 297-304 doi: 10.1007/s11708-017-0478-2

Abstract: A reverse osmosis (RO) desalination system coupled with tidal energy is proposed.The mechanical energy produced by the tidal energy through hydraulic turbine is directly used to driveIt is found that the proposed tidal energy RO system can save water cost in the range of 31.0% 41.7%The tidal RO system can save more costs at a high feed pressure or a high water recovery rate.The longer lifetime of the tidal energy RO system can save even more water cost.
