Water Diversion is Not to Blame for Phosphorus Enrichment in Taihu Lake

Zhiyuan Wang,Qiuwen Chen,Jianyun Zhang,Hanlu Yan,

Engineering doi: 10.1016/j.eng.2023.07.007

Abstract: The Water Diversion Project from the Yangtze River to Taihu Lake (WDYT) has been widely recognized as an urgent and effective engineering measure to increase water resources, ameliorate the hydrodynamics and water quality conditions, and safeguard the water supply of Taihu Basin. However, some previous studies claimed that WDYT has brought in allochthonous nutrients and should take responsibility for the dramatic increase in phosphorus loading of Taihu Lake in recent years, because Yangtze River has a higher average phosphorus concentration than Taihu Lake. To ensure correct public understanding and provide a critical response to the misconception about the source of phosphorus loading, we quantified contribution of water diversion from the Yangtze River to phosphorus loadings of Taihu Lake over the past twenty years. We reveal that WDYT only diverted 4.3% annually of total phosphorus input of Taihu Lake in the last decade and should not be responsible for the increase in phosphorus concentration and loading in Taihu Lake. We conclude that phosphorus input from the Huxi Region contribute 78% of phosphorus input of Taihu Lake and should be primarily responsible for the high phosphorus concentration of Taihu Lake. Our findings have provided constructive guidance for water resource management of Taihu Basin and phosphorus load control of the second stage of WDYT.

Effective enrichment of Zn from smelting wastewater via an integrated Fe coagulation and hematite precipitation

Zhan Qu, Ting Su, Yu Chen, Xue Lin, Yang Yu, Suiyi Zhu, Xinfeng Xie, Mingxin Huo

Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 6, doi: 10.1007/s11783-019-1178-4

Abstract: 98.5% Zn was enriched from Zn-bearing smelting wastewater. 99.5% Fe was hydrothermally precipitated into hematite nanoparticles. Highly purified hematite nanoparticles were obtained. The residual Zn was 2169 mg/L, 290 times of that in smelting wastewater. Coagulation is commonly applied to treat Zn-bearing wastewater from smelting industries (smelting wastewater), and thus the Zn-bearing sludge was considerably produced, which should be solidified before safety disposal. Herein, we demonstrated a novel approach to recycle Zn effectively from smelting wastewater via an integrated Fe coagulation and hematite precipitation method. First, smelting wastewater was coagulated by adding ferric chloride to generate Fe/Zn-bearing sludge (sludge for short). Secondly, the sludge was dissolved to generate an acid solution containing 2.2 g/L of Zn and 39.2 g/L of Fe. Thirdly, the Fe/Zn-bearing solution was hydrothermally treated, and 89% of Fe was eliminated to highly purified hematite block, whereas the percentage of Zn lost was below 1.1%. Finally, the hematite precipitates were collected, and the supernatant was hydrothermally treated again with the addition of glucose. When the molar ratio of glucose to Fe in the supernatant was 1.5, over 99.5% of Fe was precipitated in hematite nanoparticles with a diameter of 10–100 nm, and the residual Fe was 21.5 mg/L. The loss of Zn was below 0.4%, and the residual Zn in the solution was 2169 mg/L, 290 times of that in the smelting wastewater. The major mechanism for Fe removal was the hydrolysis of ferric nitrate into hematite, which was promoted by nitrate consumption in glucose oxidation. This paper is the first report of an environment-friendly method for enriching Zn without generating any waste.
