Managing water for life

Daniel P. LOUCKS, Haifeng JIA

《环境科学与工程前沿（英文）》 2012年第6卷第2期页码 255-264 doi: 10.1007/s11783-011-0359-6

摘要： Water is essential for life. In spite of the entire engineering infrastructure devoted to the treatment, regulation and beneficial uses of water, occasionally sufficient quantities and qualities of water become scarce. When this happens, just how do we decide how much less water to allocate to all of us and the activities we engage in to sustain and enhance our quality of life? This paper addresses some of the complexities of answering such a question, especially as society increasingly recognizes the need to provide flow regimes that will maintain healthy aquatic and floodplain ecosystems that also impact the economic, physical and even the spiritual quality of our lives. For we depend on these ecosystems to sustain our wellbeing. We are indeed a part of our ecosystems. We depend upon on aquatic ecosystems to moderate river flow qualities and quantities, reduce the extremes of floods and droughts, reduce erosion, detoxify and decompose waterborne wastes, generate and preserve flood plain soils and renew their fertility, regulate disease carrying organisms, and to enhance recreational benefits of river systems. This question of deciding just how much water to allocate to each water user and for the maintenance of viable aquatic ecosystems, especially when there is not enough, is a complex, and largely political, issue. This issue is likely to become even more complex and political and contentious in the future as populations grow and as water quantities and their qualities become even more variable and uncertain.

中国可持续发展水资源战略研究综合报告

中国工程院"21世纪中国可持续发展水资源战略研究"项目组

《中国工程科学》 2000年第2卷第8期页码 1-17

摘要：

我国水资源总量28000×10⁸m³，按1997年人口计算，人均水资源量为2220m³，预测到2030年人口增至16×10⁸时，人均水资源量将降到1760m³。按国际上一般承认的标准，人均水资源量少于1700m³为用水紧张的国家，我国未来水资源的形势是严峻的。

50年来，全国用水总量从1949年的1 000多亿m³增加到1997年的5 566 × 10⁸ m³,其中农业用水占75.3%，工业20.2%,城镇生活4.5%,人均综合用水量从不足200 m³增加到458 m³。当前面临的问题是，防洪安全仍缺乏保障；水资源的紧缺与用水的浪费并存；水土资源过度开发造成对生态环境的破坏；水环境恶化和水质污染迅速扩展，已到极为严重的程度。

研究报告指出，通过建设节水高效的现代农业，我国可以基本立足于现有规模的耕地和灌溉用水量，满足今后16×10⁸人口的农产品需要；预测我国用水高峰将在2030年前后出现，用水总量为（7 000〜8 000) × 10⁸ m³/a,人均综合用水量为400〜500 m³/a;全国实际可能利用的水资源量约为（8 000〜9 500) × 10⁸m³,需水量已接近可能利用水量的极限；必须严格控制人口的继续增长，同时加强需水管理，做到在人口达到零增长后，需水也逐步达到零增长；我国水资源的总体战略必须以水资源的可持续利用支持经济的可持续发展，建议从防洪减灾、农业用水、城市和工业用水、防污减灾、生态环境建设、水资源的供需平衡、北方水资源问题及西北地区水资源问题等8个方面实行战略性转变；同时必须进行水资源管理体制、水资源投资机制和水价政策的3项改革。

Power-to-chemicals: sustainable liquefaction of food waste with plasma-electrolysis

《化学科学与工程前沿（英文）》 2023年第17卷第5期页码 594-605 doi: 10.1007/s11705-022-2255-y

摘要： The increasing amount of food waste from various industrial, agricultural, and household sources is an environmental burden if managed inappropriately. Numerous waste management approaches have been developed for the disposal of food waste, but still suffer from either high cost, production of toxic by-products, or secondary environmental pollutions. Herein, we report a new and sustainable plasma electrolysis biorefinery route for the rapid and efficient liquefaction of food waste. During the plasma electrolysis process, only the solvent is added to liquefy the waste, and anions in the waste can contribute to catalyzing the biowaste conversion. While liquefying the waste, the highly reactive species produced in the plasma electrolysis process can efficiently reduce the content of O, N, and Cl in the liquefied products and oxidize most of the metals into solid residues. Especially, the removal rate of Na and K elements was greater than 81%, which is significantly higher than using the traditional oil bath liquefaction, resulting in a relatively high-quality biocrude oil with a high heating value of 25.86 MJ·kg^–1. Overall, this proposed strategy may provide a new sustainable and eco-friendly avenue for the power-to-chemicals valorization of food waste under benign conditions.

宋之平

《中国工程科学》 2001年第3卷第6期页码 9-14

摘要：

提出了一个术语“绿色供热系统”，并阐述了它应有的特征。为此，介绍了可逆型供热系统的概念和一般化供热系统模型。为了界定绿色供热系统，使用了作者设计的《单耗分析》的理论和方法。基于绿色供热系统所界定的原则，把排放物的量和有害成分大幅度地降下来的供热方案具有现实的可行性，如再与诸如蒸馏法海水淡化等技术相结合，不但具有可持续的发展空间，单就其可能产生的水量、水质以及造水成本而言，均堪与流域调水方案相竞争。

Operating mechanism and set pair analysis model of a sustainable water resources system

Chaoyang DU,Jingjie YU,Huaping ZHONG,Dandan WANG

《环境科学与工程前沿（英文）》 2015年第9卷第2期页码 288-297 doi: 10.1007/s11783-014-0642-4

摘要： There is no alternative to the world’s water resources, and their increasing scarcity is making it difficult to meet the world population’s water needs. This paper presents a sustainable water resources system (SWRS) and analyzes the operating mechanism that makes it possible to evaluate the status of such a system. A SWRS can be described as a complex coupling system that integrates water resources, social, economic and ecological systems into a whole. The SWRS’s operating mechanism is composed of dynamic, resistance and coordination components, and it interacts with and controls the system’s evolution process. The study introduces a new approach, set pair analysis theory, to measure the state of a SWRS, and an evaluation index system is established using the subsystems and operating mechanism of a SWRS. The evaluation index system is separated into three levels (goal level, criteria level and index level) and divides the index standard into five grades. An evaluation model of the SWRS based on set pair analysis theory is constructed, and an example of SWRS evaluation in Shanghai is presented. The connection degrees of the index in the three levels are calculated, and the connection degree of the goal index is calculated to be 0.342, which classifies the city’s SWRS condition as grade 2. The sustainable use of water resources in the region is determined to be at a relatively adequate level that meets the requirements of sustainable development.

From plasma to plasmonics: toward sustainable and clean water production through membranes

《化学科学与工程前沿（英文）》 2023年第17卷第12期页码 1809-1836 doi: 10.1007/s11705-023-2339-3

摘要： The increasing demand for potable water is never-ending. Freshwater resources are scarce and stress is accumulating on other alternatives. Therefore, new technologies and novel optimization methods are developed for the existing processes. Membrane-based processes are among the most efficient methods for water treatment. Yet, membranes suffer from severe operational problems, namely fouling and temperature polarization. These effects can harm the membrane’s permeability, permeate recovery, and lifetime. To mitigate such effects, membranes can be treated through two techniques: plasma treatment (a surface modification technique), and treatment through the use of plasmonic materials (surface and bulk modification). This article showcases plasma- and plasmonic-based treatments in the context of water desalination/purification. It aims to offer a comprehensive review of the current developments in membrane-based water treatment technologies along with suggested directions to enhance its overall efficiency through careful selection of material and system design. Moreover, basic guidelines and strategies are outlined on the different membrane modification techniques to evaluate its prerequisites. Besides, we discuss the challenges and future developments about these membrane modification methods.

Imprinted membranes for sustainable separation processes

Laura Donato, Enrico Drioli

《化学科学与工程前沿（英文）》 2021年第15卷第4期页码 775-792 doi: 10.1007/s11705-020-1991-0

摘要： The rapid industrial growth and the necessity of recovering and recycling raw materials increased the interest in the production of highly selective and efficient separation tools. In this perspective, a relevant input was given by the membrane-based technology and the production of imprinted membranes, which possess specific recognition properties at molecular and ionic level, offers the possibility of developing sustainable and green processes. Furthermore, the integration of imprinted membranes with traditional or membrane-based approaches is a promising strategy in the logic of process intensification, which means the combination of different operations in a single apparatus. This work discusses the concept and separation mechanisms of imprinted membranes. Furthermore, it presents an overview of their application in organic solvent nanofiltration, for the removal of toxic agents and recovery solvent, as well as valuable compounds. The recent advances in water treatment, such as pesticide removal and recovery of metal ions, are also discussed. Finally, potential applications of imprinted membranes in hybrid processes are highlighted, and a look into the future of membrane separations for water treatment and recovery of critical raw materials is offered.
