再生水集中和分散处理与供水模式的历史进程

Historical development of centralized and decentralized treatment of reclaimed water and its supply mode

污水再生处理与供水模式可以分为集中模式和分散模式。集中和分散两种模式各有利弊,科学合理的方案是集中与分散相结合,因地制宜,互为补充。以再生水系统发展比较成熟的美国和日本为例,对比分析了再生水集中和分散处理模式的发展进程和特点。同时,结合北京市小区分散式处理系统的发展过程,对我国特别是北京市分散模式的现状进行了总结,从建设、设计、运行和管理等方面指出了目前北京市住宅小区中水处理存在的主要问题。

Wastewater reclaimed treatment and water supply mode can be divided into centralized and decentralized models. Centralized and decentralized models have their own advantages and disadvantages. The scientific and reasonable solution is to focus on the combination of decentralization, local conditions, complement each other. In this study, the development process and characteristics of reclaimed water for centralized and decentralized treatment are compared and analyzed in the United States and Japan. At the same time, the combination of Beijing City residential development process of decentralized processing sys- tem, the status of China and Beijing City dispersion patterns are summarized. From the aspects of con- struction, design, operation and management, the main problems existing in the reclaimed water treatment of residential quarter are pointed out in Beijing.
