摘要

本文对缅甸主要城市仰光和曼德勒的污水管理实践进行了比较分析,重点从仰光的经验中吸取宝贵的经验教训,并提出了改善曼德勒生活污水管理的建议,通过SWOT分析得出结论。这两个城市都面临着快速城市化的挑战,导致未经处理的排放到环境中。该研究指出了仰光和曼德勒面临的共同挑战,如有限的处理能力、环境问题和资金缺口。尽管仰光的容量不高,但分散式集中式战略是一种成功的方法。结果显示,17.5%的分散式污水处理系统(DEWATS)用户非常满意,45%的用户一般满意。仰光在集中系统方面的经验表明,需要几年时间才能覆盖整个城市的治疗,从而导致支付收入支出的问题。如果曼德勒采取类似的措施,它可能会遇到同样的问题。建议的方法是与DEWATS实施一个综合系统,这提供了一个更好的解决方案。曼德勒可持续废水管理的建议包括利益相关者积极参与决策、促进社区参与和提供培训。透明度和共同责任是成功的关键。解决膜污染、污泥处理和实施每月收费是可持续实施的必要条件。要发展具有成本效益和高效率的废水处理系统,同时保障公众健康和环境,就必须采取综合办法,并进行环境和社会影响评估。这些见解提供了更广泛的影响,指导发展中国家采取更有效和对环境负责的废水管理做法。

Lesson Learned from Yangon to Mandalay on Wastewater Treatment Systems
This paper presents a comparative analysis of wastewater management practices in Myanmar’s major cities, Yangon and Mandalay, with a focus on drawing valuable lessons from Yangon’s experiences and proposing recommendations for the improvement of Mandalay’s domestic wastewater management, drawing insights from a SWOT analysis. Both cities are facing challenges due to rapid urbanization, leading to untreated discharge into the environment. The study identifies common challenges in both Yangon and Mandalay, such as limited treatment capacity, environmental concerns, and funding gaps. The decentralized-centralized strategy is a successful approach for Yangon even though the capacity is not high. Results showed that 17.5% of Decentralized Wastewater Treatment Systems (DEWATS) users were highly satisfied and 45% were somewhat satisfied. Yangon’s experience with centralized systems showed that it took several years to cover the entire city for treatment, resulting in issues to cover revenue expenditures. If Mandalay adopts a similar, it will likely encounter the same issues. A recommended approach would be to implement an integrated system with DEWATS, which offers a better solution. The recommendations for sustainable wastewater management in Mandalay include active stakeholders’ involvement in decision-making, promoting community participation, and providing training. Transparency and shared responsibility are crucial for success. Addressing membrane fouling, sludge disposal, and implementing monthly fees are essential for sustainable implementation. An integrated approach along with environmental and social impact assessments are necessary to develop a cost-effective and efficient wastewater treatment system while safeguarding public health and the environment. These insights offer broader implications, guiding developing countries towards more effective and environmentally responsible wastewater management practices.

期刊介绍: The Environment and Natural Resources Journal is a peer-reviewed journal, which provides insight scientific knowledge into the diverse dimensions of integrated environmental and natural resource management. The journal aims to provide a platform for exchange and distribution of the knowledge and cutting-edge research in the fields of environmental science and natural resource management to academicians, scientists and researchers. The journal accepts a varied array of manuscripts on all aspects of environmental science and natural resource management. The journal scope covers the integration of multidisciplinary sciences for prevention, control, treatment, environmental clean-up and restoration. The study of the existing or emerging problems of environment and natural resources in the region of Southeast Asia and the creation of novel knowledge and/or recommendations of mitigation measures for sustainable development policies are emphasized. The subject areas are diverse, but specific topics of interest include: -Biodiversity -Climate change -Detection and monitoring of polluted sources e.g., industry, mining -Disaster e.g., forest fire, flooding, earthquake, tsunami, or tidal wave -Ecological/Environmental modelling -Emerging contaminants/hazardous wastes investigation and remediation -Environmental dynamics e.g., coastal erosion, sea level rise -Environmental assessment tools, policy and management e.g., GIS, remote sensing, Environmental -Management System (EMS) -Environmental pollution and other novel solutions to pollution -Remediation technology of contaminated environments -Transboundary pollution -Waste and wastewater treatments and disposal technology
