024 Using bio-based CaCO3 functionalized sediment to simultaneously remove algae and COD through adsorption and sedimentation in water source reservoirs
In-situ turbidity enhancement can suppress algal growth in reservoirs but often exacerbates chemical oxygen demand (COD) accumulation due to incomplete organic removal. This study presents a biologically synthesized bio-CaCO~3~-modified sediment, engineered via Bacillu s-induced carbonate precipitation, to simultaneously control algae and reduce COD. The material forms 15–30 nm core–shell clusters with enriched –OH/–COOH groups and mesopores (~19.76 nm), confirmed by SEM, XRD, FTIR, and BET (+1.02 m2 g-1). Adsorption tests against Microcystis aeruginosa, Chlorella, and Limnothrix showed Langmuir-type monolayer binding (R2 > 0.97) and pseudo-second-order kinetics. XDLVO theory and DFT analysis revealed strong EPS–Bio-CaCO~3~ interactions ($\Delta E_\text{AB}$ = 31.28 mJ m-2; $\Delta E_\text{ads}$ = –1.07 ev). Optimal conditions (7.5 wt% CaCO~3~, 56% residual Ca2+, 85 min) achieved 93.8% Chl-a removal, 88.6% COD reduction, and 87.5% turbidity control (R2 = 0.98), with minimal Ca2+ leaching. By integrating chemisorption, interfacial adhesion, and pore confinement, this material provides a stable, eco-friendly strategy for dual pollutant control and in-situ sediment remediation.

022 Effects of Oxygenation Resuspension on DOM Composition and Its Role in Reducing Dissolved Manganese in Drinking Water Reservoirs
水源沉积物厌氧环境是饮用水系统中锰释放的关键驱动因素。增强沉积物氧化可抑制锰释放，但不同氧化条件下锰的形态转化机制尚不明确。本研究通过实验室模拟，考察了沉积物在不同溶解氧水平（0、2、5、7 mg/L）含氧水层中的暴露情况。结果表明，锰释放量与溶解氧呈显著负相关（R²=0.93，p=0.034），氧气促使溶解性有机物（C2、C3组分）发生反应并形成羟基、羧基等功能基团，通过吸附或络合作用去除锰（C2：R²=0.57，p<0.001；C3：R²=0.53，p<0.001）。对六个水库的实地研究确定了沉积物再悬浮调控锰风险的运行阈值（补偿阈值：17.4 μg/L；风险阈值：中国标准95.5 μg/L；WHO标准70.8 μg/L）。这些发现阐明了锰与有机物的相互作用机制，可为水源系统锰与藻类协同去除提供实践指导。

021 Green Light Suppresses Cell Growth but Enhances Photosynthetic Rate and MIB Biosynthesis in PE-Containing Pseudanabaena
2-甲基异茨醇（MIB）是饮用水系统中由蓝藻在光合色素生物合成过程中产生的典型霉味物质。本研究通过诱导含藻红蛋白（PE）的产MIB蓝藻——灰色假鱼腥藻（Pseudanabaena cinerea）在不同光色下的趋色适应性，揭示其生理调控机制。结果表明：红光通过激活三羧酸（TCA）循环及相关代谢过程促进藻体生长，而绿光显著提升光合色素含量及电子传递效率；MIB产量与叶绿素a（Chl a）含量呈非线性相关，符合对数-线性模型（R² = 0.74，p < 0.01），该关系在RNA水平通过mic与chlG基因表达量的强相关性（R² = 0.85，p < 0.01）获得验证。模型显示相较于Chl a合成，MIB生物合成的碳通量分配不足2%，表明MIB合成与光合色素生产具有协同性而非竞争性。野外观察发现水体浊度增加导致的光谱红移通过改变光合色素组成降低了MIB水平。本研究深化了对变化光环境下产MIB蓝藻生理机制的理解，为地表水MIB污染防控提供了理论依据。
