中水回用处理系统 Reclaimed Water Reuse Treatment System

中水回用是通过物理、化学及生物处理技术，将生活污水、工业废水等处理至特定水质标准，转化为可回用的非饮用水资源，实现水资源的闭环管理。中水回用可以替代传统水源用于非饮用场景（如工业冷却、园林灌溉、道路冲洗、消防用水等），减少对地下水和地表水的过度开采。还可以降低污水直接排放对自然水体的污染负荷，缓解水体富营养化、重金属累积等环境问题。

中水回用是实现水资源可持续利用的核心技术路径，兼具环境修复、经济增值与社会发展三重价值，是践行“双碳”战略和生态文明建设的重要实践载体。

1. 环境效益

• 减少污水排放量，保护流域生态健康；
• 缓解水资源短缺地区的水危机。

2. 经济效益

• 降低企业新鲜水取用成本；；
• 减少污水处理费及排污税费支出。

3. 社会效益

• 提升城市水资源韧性，提升公共用水安全；
• 推动循环经济模式落地，增强公众节水意识。

Water reclamation and reuse involves treating domestic wastewater and industrial effluents through physical, chemical, and biological technologies to meet specific water quality standards, converting them into non-potable reusable resources for closed-loop water management. This practice substitutes conventional water sources in non-drinking applications (e.g., industrial cooling, landscape irrigation, road cleaning, and firefighting), thereby reducing overexploitation of groundwater and surface water. It also mitigates pollution loads from direct wastewater discharge into natural water bodies, addressing environmental challenges such as eutrophication and heavy metal accumulation.

As a core technological pathway for sustainable water resource utilization, water reuse delivers triple value: environmental restoration, economic enhancement, and social development. It serves as a critical implementation vehicle for China's "Dual Carbon Strategy" (Carbon Peak and Carbon Neutrality) and ecological civilization development.

1. Environmental Benefits
• Reduces wastewater discharge volume to protect watershed ecosystem health
• Alleviates water crises in water-scarce regions

2. Economic Benefits
• Lowers corporate costs for freshwater procurement (potential reduction: 30-60%)
• Decreases expenditures on wastewater treatment fees and pollution discharge taxes

3. Social Benefits
• Enhances urban water resource resilience and public water security
• Advances circular economy practices and strengthens public awareness of water conservation
