北京通州新城建设中再生水利用规划及其实施

Planning and implementation of recycled water use in construction of Tongzhou New Town in Beijing

通州新城是北京市规划的11个新城之一,是东部发展带的重要节点。由于该地城区范围内污水管网尚未完善,部分污水未经处理直接排入河内,严重污染了本地区的水环境,环境质量问题已成为当地经济健康发展和人民生活水平提高的重要障碍。根据城市总体规划,在新城区内应形成完善的排水系统,通过污水管道的布置和再生水厂的建设,将污水引入再生水厂进行处理及再利用。本文介绍了通州新城污水治理的规划及实施情况,并对在建的河东再生水厂的较为先进的MBR处理工艺进行了介绍说明。

Tongzhou New Town is one of 11 new urban areas planned in Beijing, and it is the key node in the eastern develop- mere zone of the city. As the sewage pipeline networks are not completed yet and a part of untreated sewage is directly discharged into rivers directly, the water environment therein is heavily polluted; which becomes an important barrage to obstruct the local health economic development and the enhancement of the people＇ s living standard. In accordance with the general urban plan- ning concerned, a completed drainage system must be formed in the new town, i. e. diverting the sewage into recycled water plant for treatment and re-use through the layout of sewage pipeline system and the construction of recycled water plant. The planning and implementation of the sewage treatment for Tongzhou New Town is introduced herein, and then the more advanced MBR treat- ment technology of Hedong Water Recycling Plant under construction is described as well.
