Abstract ：
制药废水具有水质波动大、可生化性差及化学需氧量高等特点,一直是废水处理中的难题.其中的抗生素由于使用量大导致向环境中持续排放,并表现出"伪持久性"滞留的特点,难以从水体中彻底去除.为了实现制药废水的高效处理,分析了制药废水的水质特性以及其中抗生素去除的难点,系统阐述了生物炭的基本特性及其强化污染物去除的原理,总结了常规污水处理工艺在去除抗生素方面存在的问题,梳理并综述了生物炭耦合工艺提升污水处理效果的研究进展.结果显示,生物炭材料的多孔结构、带表面电荷及丰富的特殊表面官能团等特性使其具有良好吸附抗生素的能力,通过与常规污水处理工艺相结合可显著提高对制药废水的处理效果,如生物炭的引入强化了膜生物反应器、活性污泥法、厌氧消化及高级氧化对抗生素的去除效果,同时提高了系统的稳定性,降低了工艺物耗和能耗等.建议进一步开展生物炭制备过程与成炭特性的相关性研究,加强生物炭耦合工艺去除污染物机理的探究,推广其在制药废水处理中的应用,以推动制药废水处理技术的创新和进步.

Abstract ：
This study focused on Duihekou Reservoir, a typical deep-water reservoir located in the southeastern hilly and mountainous areas of China. A one-year field investigation was conducted to collect columnar sediment column samples from the main water bodies. Detailed analyses were conducted on the phosphorus concentrations, fractions, interstitial water profile characteristics, and spatiotemporal changes of fluxes across the sediment-water interface. The results showed that the average total phosphorus (TP) concentrations in the surficial sediment of the reservoir ranged from 470.8 to 1012.3mg/kg, with an average of 688.4 ± 186.48mg/kg. An increasing trend of TP concentrations was discovered from the upstream to downstream. The most severe phosphorus pollution was discovered around the dam. The phosphorus fractions followed a descending order of Al-P (352.61mg/kg) > Fe-P (98.10mg/kg) > Res-P (88.77mg/kg) > Ca-P (72.42mg/kg) > Org-P (33.38mg/kg) > Ex-P (1.64mg/kg). Overall, the sediment in the entire reservoir acted as a source of phosphorus to the water, with the highest risk of release in autumn and most of the sediment in winter presenting as a sink of phosphorus. The average static release flux and diffusion flux of phosphorus were (0.81±2.34) and (2.15±3.47) mg/(m2·d), respectively. The annual phosphorus release amounts obtained by the two methods were 1.92 and 3.67 tons respectively, with the highest release amount in autumn. The conversion of Fe-P might be an important factor controlling phosphorus release from the sediment. The anaerobic dissolution and release of Fe-P caused by oxygen stratification will increase the phosphorus concentration in the lower layer of the water column, which would subsequently increase the phosphorus concentration in the whole water column after thermal stratification. After a large amount of phosphorus is released in autumn, more attention should be paid to the phosphorus concentration in the water influenced by the subsequent thermal inversion. © 2024 Chinese Society for Environmental Sciences.

Abstract ：
Antibiotics in hospital wastewater has become a critical issue due to their potential risks to human health and ecosystems. Biochar as a cost-effective and environmental-friendly carbon material has been employed for removing antibiotics. This article gives a holistic view of the properties of advanced biochar-based materials and clarifies mechanisms on removal of specific antibiotics from hospital wastewater. The increased pyrolysis temperature prepares the modified biochar with higher porosity and larger specific surface for enhancing adsorption. The metal-modified biochar possesses abundant functional groups, limits the leaching of metal ions, and increases the conductivity for improving activation of advanced oxidation process (AOP). Adsorption is significantly affected by the pyrolysis temperature, solution pH, and properties of modified biochar and antibiotics. The metal-modified biochar-assisted AOP can effectively degrade the pollutants via generating more reactive oxygen species. Weak acidic and/or weak alkaline condition promotes the degradation process in persulfate and peroxymonosulfate systems or during electrochemical oxidation process. Antibiotics removal at a wide pH range (3-11) can be achieved using Fenton-like and photo-Fenton systems with the presence of metal-modified biochar. Future research should focus on development of novel biochar with high reusability and great capability in removing a broad range of specific antibiotics.

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/(m2·d)和(2.15±3.47)mg/(m2·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 ：
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 ：
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 ：
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 ：
为探究天然煤矸石在雨水浸泡淋滤作用下重金属元素的释放规律及特征,通过扫描电镜(SEM)对天然煤矸石进行表征以观察其淋滤前后的微观形貌,借助X射线衍射(XRD)技术测定煤矸石淋滤前后的矿物成分组成及变化情况.结合模拟降水连续静态浸泡与动态淋滤试验,考察在不同固液比、粒径、pH、土壤介质条件下煤矸石中重金属元素的释放规律与特性.结果表明:①淋滤后的煤矸石表面凹凸结构较多,淋滤前后煤矸石中各矿物相含量差异较小.②As、Mn的浸出浓度均较高,最大释放率大小表现为As>Cd>Cu≈Ni>Mn>Cr>Zn>Pb.As的累积释放对周边土壤环境以及地下水产生不利影响的风险较高.③连续动态淋滤试验在pH为3时,Mn、Cu、Zn、Ni的累积释放量明显较高,As、Cr在中性条件下的累积释放量高于在酸性条件下.引入土壤介质这一因素后,Cr、As的累积释放量均明显减少,这两种重金属元素均呈现出在土壤中积累的状态.研究显示:对于相同煤矸石堆存量,降雨量越大,重金属的释放总量越高,固液比为1:20时,As释放量最高可达2.822μg/L;Cr、As呈现出在土壤中积累的状态,煤矸石淋滤后Cr、As对土壤存在潜在污染风险,同时也需考虑其对周边地下水的影响.
