Climate change and its consequences for water and wastewater management

Peter A. WILDERER

《环境科学与工程前沿（英文）》 2009年第3卷第1期页码 1-1 doi: 10.1007/s11783-009-0001-z

摘要： Life, in combination with solar radiation and abiotic processes, is most probably the reason why liquid water has existed on Earth for over billions of years, and the global mean temperature has remained in a life-enabling range. Efforts to limit or even reverse global warming must be derived from the knowledge of the Earth’s complex life-support system. In this context, the balance between liquid and gaseous water plays a crucial role, and water management becomes an important field of innovation and action, globally, on the scale of watersheds but also on the very local level. Cascading use, reuse, and temporary storage of water in urban settings must be considered to limit over-extraction of water from natural resources, and to maintain the life supporting function of ecosystems. At the same time, public health requirements, cost efficiency, and reliability demands are to be met.

Role of water chemistry on estrone removal by nanofiltration with the presence of hydrophobic acids

Xue JIN,Jiangyong HU

《环境科学与工程前沿（英文）》 2015年第9卷第1期页码 164-170 doi: 10.1007/s11783-014-0747-9

摘要： Hydrophobic acid organic matter (HpoA) extracted from treated effluent has been known to improve the rejection of steroid hormone estrone by reverse osmosis (RO) and nanofiltration (NF) membranes. In this study, the effects of solution chemistry (solution pH and ionic strength) on the estrone rejection by NF membrane with the presence of HpoA were systematically investigated. Crossflow nanofiltration experiments show that the presence of HpoA significantly improved estrone rejection at all pH and ionic strength levels investigated. It is consistently shown that the “enhancement effect” of HpoA on estrone rejection at neutral and alkaline pH is attributed to the binding of estrone by HpoA macromolecules via hydrogen bonding between phenolic functional groups in feed solutions, which leads to an increase in molecular weight and appearance of negative charge. The membrane exhibited the best performance in terms of estrone rejection at pH 10.4 (compared to pH 4 and pH 7) as a result of strengthening the electrostatic repulsion between estrone and membrane with the presence of HpoA. At neutral pH level, the ability of HpoA macromolecules to promote estrone rejection became stronger with increasing ionic strength due to their more extended conformation, which created more chances for the association between estrone and HpoA. The important conclusion of this study is that increasing solution pH and salinity can greatly intensify the “enhancement effect” of HpoA. These results can be important for NF application in direct/indirect potable water reuse.

摘要：

In the microalgae harvesting process, which includes a step for dewatering the algal suspension, directly reusing extracted water in situ would decrease the freshwater footprint of cultivation systems. Among various algae harvesting techniques, membrane-based filtration has shown numerous advantages. This study evaluated the reuse of permeate streams derived from Scenedesmus obliquus (S. obliquus) biomass filtration under bench-scale and pilot-scale conditions. In particular, this study identified a series of challenges and mechanisms that influence the water reuse potential and the robustness of the membrane harvesting system. In a preliminary phase of this investigation, the health status of the initial biomass was found to have important implications for the harvesting performance and quality of the permeate stream to be reused; healthy biomass ensured better dewatering performance (i.e., higher water fluxes) and higher quality of the permeate water streams. A series of bench-scale filtration experiments with different combinations of cross-flow velocity and pressure values were performed to identify the operative conditions that would minimize energy requirements while maximizing water productivity. The optimal conditions, 2.2 m·s⁻¹ and 1.4 bar (1 bar = 10⁵ Pa), respectively, were then applied to drive pilot-scale microfiltration tests to reuse the collected permeate as a new cultivation medium for S. obliquus growth in a pilot-scale photo-bioreactor. The investigation revealed key differences between the behavior of the membrane systems at the two scales (bench and pilot). It indicated the potential for beneficial reuse of the permeate stream as the pilot-scale experiments ensured high harvesting performance and growth rates of biomass in permeate water that were highly similar to those recorded in the ideal cultivation medium. Finally, different nutrient reintegration protocols were investigated, revealing that both macro- and micronutrient levels are critical for the success of the reuse approach.

Reuse of heavy metal-accumulating

《环境科学与工程前沿（英文）》 2014年第8卷第6期页码 952-959 doi: 10.1007/s11783-013-0619-8

摘要： Phytoremediation technology is regarded as a simple and efficient way to remove heavy metals from contaminated soil. A reasonable disposal of metal hyperaccumulators is always a major issue in waste reuse and resource-saving. The heavy metal-accumulating (L.) was investigated where heavy metals were desorbed by a facile acid-treatment. The result indicated that more than 90% of heavy metals (Zn, Pb and Cu) was extracted from with 0.2 mmol·L HCl. The plant residue was used to adsorb heavy metals ions. The adsorption fitted the Langmuir isotherm model with the saturation adsorption capacity of 9.5 mg·g Zn , 36.2 mg·g Pb and 12.9 mg·g Cu , and the surface complexation and the backfilling of heavy metal-imprinting cavities existed simultaneously during the adsorption. The treatment of wastewaters indicated that the plant residue exhibited a high removal rate of 97% for Cu. Also, the material could be recycled. The method offers a new disposal approach for heavy metal hyperaccumulator.

面向未来饮用水净化的OSRO技术——基于河岸过滤的一步反渗透技术 Perspective

Yujia Zhai, 刘刚, Walter G.J. van der Meer

《工程（英文）》 2022年第9卷第2期页码 27-34 doi: 10.1016/j.eng.2021.02.015

摘要：

水环境中出现的新污染物给饮用水处理厂带来了巨大挑战。由于新污染物的浓度较低、特性不明，传统的水处理工艺无法对其进行有效去除，因此技术、经济和环境友好的水净化技术日益重要。本文介绍了一种由河岸过滤（riverbank filtration, RBF）和反渗透（reverse osmosis, RO）组成的一步反渗透（one-step reverse osmosis, OSRO）概念，用于饮用水处理。OSRO概念结合了相对成本较低的河水自然预处理与先进的工程净化系统。RBF提供了一个连续天然水源，具有稳定的水质和强大的污染物屏障。与直接提取地表水相比，由于预先清除了颗粒物、有机物、有机微污染物（organic micro-pollutant, OMP）和微生物，RBF成为基于RO膜的净化系统的理想水源。OSRO处理可以去除几乎99.9%的颗粒物、病原体、病毒和OMP，以及绝大多数的营养物质，从而满足无氯饮用水的要求，且具有较高的生物稳定性。与标准的常规净化步骤（包括喷淋过滤器过滤、软化操作和活性炭吸附）相比，OSRO处理更具有成本效益。人工滤池（artificial bank filtration, ABF）与砂滤系统相结合，起到人工补给的作用，是OSRO概念中RBF的替代方案，用于从当地可用资源中供应饮用水。本文建议以风能作为替代能源来实施OSRO，以提高可持续性和可再生性。本文还提出了一种基于OSRO的分散式系统，用于水的回收和再利用。本文建议未来的水处理应侧重于自然系统和工程系统的结合，通过技术上有效、经济上可行、资源可重复利用和与环境相关的方式提供饮用水。

Technical measures to achieve a cleaner production mode for recycled paper mills

Chao HE, Zhaolin GU, Shucheng YANG, Jidong LIANG, Weina DAI, Yanling HE

《环境科学与工程前沿（英文）》 2010年第4卷第4期页码 466-474 doi: 10.1007/s11783-010-0242-x

摘要： China’s paper production reached 79.8 ×10 t in 2008 and ranked number one in the world. Because of its high consumption of water, energy and materials and its serious pollution, the present processes are not likely to be sustainable. An alternative, the closed Water Loop-Papermaking Integration (WLPI) method, is put forward in this paper. The WLPI method can be realized in a recycled paper mill by adding technologies and using recycled water. Many industrial case studies have shown that a large quantity of water, energy and materials can be saved, and the quantity of waste sludge and wastewater discharge was minimized by using the WLPI method. The design of the water reuse system, control of calcium hardness, water recycling and minimal waste sludge are discussed. Anaerobic technology plays an important role in the WLPI method to lower cost, energy use and waste. In the brown paper and coated white board production, zero-effluent discharge can be realized. Fresh water consumption is only 1–2 m ·t . For the paper mills with deinking and bleaching processes, about 10 m ·t of fresh water and a similar amount of effluent discharge are needed. Power saving using anaerobic technology is 70% when recycled water is used in comparison with the conventional activated sludge process. Waste sludge can be decreased to about 5% of the initial process due to reuse of the waste sludge and the lower bio-sludge production of the anaerobic process.
