Abstract ：
泉州南翼国家高新区作为一个刚成立不久的新区，水环境治理工作是其建设中必不可少的一部分内容。通过调查泉州南翼国家高新区水环境现况发现水体黑臭现象较多，水环境污染治理迫在眉睫。对水环境污染成因进行分析，发现原因主要有5个方面：城镇化进程的加剧、农业化学品的滥用、畜禽养殖废水的排放、工业园区的大规模增加和水生态系统的脆弱性。依据水污染的成因提出5条水污染治理策略，分别为：雨污管网的完善、污水处理厂的升级改造、减少水环境污染的治理方式、水生态修复与调水、共同参与防止水体污染。上述举措的实施将有利于推进泉州南翼国家高新区的水生态建设与可持续发展。

Abstract ：
SWMM作为一种模拟降雨情况的软件，由于其模型参数在经验范围内选取的不确定性，随着模型不断地向前运行演绎，误差会持续累积，最终影响模型的模拟结果，而传统的参数率定方法则具有效率低、准确度差等缺点。为此，利用MATLAB软件调用SWMM的水力演算程序来完成两者的数据交互与集成，结合多元逐步回归法筛选出敏感性高的参数作为率定对象，进而通过数值实验的方式以敏感性分析结果为依据使用Bayes-MH机器学习算法实现SWMM参数的自动率定。对于不同的实测降雨场景，自动率定的结果均能够顺利输出，参数匹配度达95%以上，表明了该方法具备优秀的稳定性、自适应性与全范围寻参能力。

Abstract ：
以东南丘陵山区典型深水水库对河口水库为研究对象,开展了1a的原位调研,在主要水域内采集原位柱状沉积物样品,分析了沉积物磷的含量、赋存形态、间隙水剖面特征以及沉积物-水界面交换通量的时空变化特征.结果表明:对河口水库表层沉积物总磷(TP)含量变化范围为(470.8～1012.3)mg/kg,平均值达到(688.4±186.48)mg/kg,呈现从上游至下游逐渐增加的趋势,下游坝前区域磷污染最为严重;沉积物中各形态磷含量大小顺序依次为:铝结合态磷(352.61mg/kg)>铁结合态磷(Fe-P)(98.10mg/kg)>闭蓄态磷(88.77mg/kg)>钙结合态磷(72.42mg/kg)>有机磷(33.38mg/kg)>可交换态磷(1.64mg/kg).全库沉积物总体表现为磷的释放源,其中,秋季释放风险最高,冬季大部分区域沉积物从磷释放的源转变为汇;全年平均静态释放通量和扩散通量分别为(0.81±2.34)mg/(m~2·d)和(2.15±3.47)mg/(m~2·d),2种方法所得全年磷释放量分别为1.92和3.67t,秋季释放量最大.铁结合态磷(Fe-P)的转化可能是控制沉积物-水界面磷源-汇转换的重要原因,由氧分层导致的沉积物厌氧及铁结合态磷(Fe-P)溶解释放将增加下层水体磷浓度,并在水体逆温后增加水柱总体磷浓度.在秋季大量磷释放之后,应更加关注随后的逆温对整个水体磷浓度的影响.

Abstract ：
In order to explore the release law and characteristics of heavy metals in natural coal gangue under the rainwater soaking and leaching, scanning electron microscope (SEM) was used to observe the microscopic morphology of natural coal gangue and X-ray diffraction (XRD) was used to determine the mineral composition and changes before and after leaching. The release law and characteristics of heavy metals in coal gangue were investigated by continuous static soaking and dynamic leaching tests with simulated precipitation under different solid-liquid ratio, particle size, pH and soil medium conditions. The results show that: (1) SEM and XRD analysis results reveal that the surface of natural coal gangue has a layered structure with high smoothness, and after leaching, the surface of coal gangue presents more concave-convex structures. There is small change in the content of each mineral phase, therefore the coal gangue has high stability during natural rainfall leaching process. (2) The simulated continuous static soaking test shows that the leaching content of As and Mn is higher, and the release rates are ranked as As>Cd>Cu≈Ni>Mn>Cr>Zn>Pb. Among them, the cumulative release of As poses a higher risk of adverse effects on the surrounding soil environment and groundwater, and the leaching of Cu has two stages: rapid release and stable release. Zn, Pb, and Cd belong to the late-stage release elements; Cr and As belong to indirect release elements; Mn belongs to fast release elements; and Ni belongs to slow release elements. (3) The continuous dynamic leaching test shows that the cumulative release of Mn, Cu, Zn and Ni is significantly higher at pH 3.0, and the cumulative release of As and Cr under neutral conditions is higher than that under acidic conditions. After the introduction of the soil medium, the cumulative release of Cr and As decreased significantly, indicating that both heavy metals are adsorbed the soil. The research shows that for the same stack of coal gangue, the release of heavy metals is higher with high rainfall. The maximum release of As can reach 2.822 μg/L at a solid-liquid ratio of 1∶20. Because Cr and As are accumulated in the soil, after leaching of the coal gangue, Cr and As pose potential risk of polluting the soil, and the impact on surrounding groundwater should also be considered. © 2023 Editorial Board, Research of Environmental Sciences.

Abstract ：
Phosphate recovery from water is essential for reducing water eutrophication and alleviating the phosphorus resource crisis. In this study, spent coffee grounds and CaCl2 were used as raw materials and a modifier, respectively, to create a novel calcium modified biochar (MBC) for removing phosphorus from water. The modified biochar (MBC) was the best at removing phosphorous when the modifier concentration was 1.5 M with theoretically maximum adsorption capacity of 70.26 mg/g. MBC also performed well in the wide pH range of 3-11 under different phosphorus concentration gradients, with phosphorus removal efficiency of more than 50 %. According to kinetic analysis, the adsorption process at low phosphorus concentrations (50-100 mg/L) can be more properly described by the pseudo-first-order model, while the pseudo-second-order model best describes the adsorption process at high concentrations (200-600 mg/L). The thermodynamic analysis indicated that the adsorption process was spontaneous and endothermic. Characterization results revealed that surface precipita-tion, complexation, and ligand exchange were the dominant mechanisms of phosphorus adsorption. MBC has great potential to recover phosphorus from wastewater.

Abstract ：
The production of Integrated circuits (ICs) generates wastewater with a high concentration of residual fluoride ions, necessitating highly efficient fluorine removal methods. In this study, a novel composite carrier was developed using a hydrothermal synthesis method to load Al-MOF and biochar (BC) onto polyurethane foam (PUF), resulting in the composite foam of Al-MOF-PUF@BC. The results showed that the composite carrier exhibited a stable fluoride removal effect, with a maximum adsorption capacity of 16.52 mg/g at room temperature. The adsorption isotherm curves were consistent with the Langmuir isotherm model, and the adsorption kinetics were well-described by the pseudo-first-order model. The mechanism of fluorine adsorption on Al-MOFPUF@BC was ligand exchange with hydroxyl groups and the formation of F-Al bonds. Density functional theory (DFT) calculations revealed that the adsorption energy reached -246.7 eV, indicating stable adsorption for fluoride ions. The composite foam demonstrated excellent regenerative properties and was effective for fluoride removal in actual IC wastewater.

Abstract ：
Extensive studies have been carried out on phosphate removal by zero valent iron (ZVI). Different mechanisms of phosphate removal by ZVI such as phosphate adsorption and precipitation of ferric phosphate and vivianite (Fe3(PO4)2.8H2O) have been reported. In this study, attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), X-ray powder diffraction (XRD), and X-ray absorption near edge spectroscopy (XANES) were used to elucidate the mechanisms of phosphate removal by micron-scale zero-valent (mZVI). Time-series ATR-FTIR analysis revealed that phosphate was removed by ZVI in two steps: a) adsorption of phosphate in the first 3 days, and b) slow conversion of the adsorbed phosphate into the precipitated form in 6 days. XRD and XANES analysis determined that iron oxides, ferric ion, and ZVI with oxide layer inhibited the formation of vivianite, resulting in the formation of phosphate precipitates, such as H2Fe(II)P2O7. The results suggested that phosphate is removed by ZVI mainly through precipitation under aerobic conditions. The knowledge gained in this study improves the fundamental understanding of the phosphate removal processes via ZVI.

Abstract ：
针对SWMM模型LID（低影响开发）参数的敏感性编程分析及其取值对模拟的影响，编写了MATLAB、Visual Basic.NET代码，选用修正的Morris筛选法与多元逐步回归法，分析了福州大学晋江科教园SWMM模型透水铺装、绿色屋顶、生物滞留带29个经验参数的敏感性。结果表明，对径流总量与COD总量显著敏感的是LID利用模块参数：处理不渗透面积百分比，其是LID模拟关键参数；透水铺装参数对径流总量的敏感性与降雨强度呈负相关，绿色屋顶、生物滞留带参数对径流总量的敏感性与降雨强度呈正相关，3种LID设施参数对COD总量的敏感性较为稳定，表明LID控制模块参数对不同目标变量呈现不同的敏感性；多元逐步回归法的敏感性参数多于修正的Morris筛选法，前者能全面探究参数与目标变量的线性关系以及参数相互作用对结果的影响。
