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.

Enhanced nitrogen removal reliability and efficiency in integrated constructed wetland microcosms using

Frontiers of Environmental Science & Engineering 2012, Volume 6, Issue 1,   Pages 140-147 doi: 10.1007/s11783-011-0286-6

Abstract: The purpose of this study is to reduce the seasonal fluctuation and enhance the efficiency of nitrogen removal in vertical flow-horizontal subsurface flow (VF-HSF) constructed wetlands. Two sets of VF-HSF constructed wetlands were built, VF1-HSF1 and VF2-HSF2, and a zeolite section was placed in VF2. The results showed that VF2-HSF2 compared to VF1-HSF1 was not only a more reliable nitrogen removal method, but also enhanced the nitrogen removal efficiency by 50%. The average apparent rate of nitrogen removal in VF2-HSF2 reached to 2.52 gN·m ·d , which doubled the rate in VF1-HSF1. Plant uptake and organic nitrogen sediment accounted for 12% and 6% of the total nitrogen removal in VF1-HSF1, respectively, and 10% and 4% in VF2-HSF2, respectively. Biologic nitrogen removal was the dominant mechanism, which accounted for 79% and 87% of the total nitrogen removal in VF1-HSF1 and VF2-HSF2, respectively. Ammonia adsorbed by zeolite during the cold seasons was desorbed, and then nitrified in warm seasons, which resulted in a bioregeneration efficiency of 91%. Zeolite in VF was capable of transferring ammonia from cold seasons to warm seasons as well as enhancing nitrification, which was accompanied by high potential denitrification in HSF that reinforced the efficiency and relieved seasonal fluctuation of nitrogen removal in VF-HSF.
