摘　　要：宜兴市农村污水管网项目共涉及18个乡镇、街道,其中村庄503个、道路108条,充分结合该地区南高北低、河网密布的地形特征,针对其村庄规划布局分散、排水设施不完善、污水变化系数大等难题,秉持“能集中则集中、宜分散则分散”的原则进行“一村一策”方案设计。设计师驻场实地勘察定线,采取纳管、相对集中、分散处理等多种治理模式,减少了污水直排自然受纳水体的水量,降低了环境风险;发明了一种适应现场条件的新型沿河架管方式,解决了施工不便的难题;同时创新性地应用了一种新型消能防坠板,优化了传统消能井,有效解决了下游管道溢水问题。The rural sewage network project of Yixing City involves 18 towns and streets,including 503 villages and 108 roads.Based on the topographic features of high south and low north and dense river network in this area,the“one village,one policy”scheme was designed according to the principle of“centralization if possible,decentralization if desirable”,so as to solve the problems such as scattered village planning and layout,lack of drainage facilities and large variation coefficient of sewage.The designers stationed on-site to survey and determine the pipeline route,and a variety of treatment models such as sewage collecting into the municipal network,relatively centralized treatment and decentralized treatment were adopted to reduce the sewage volume directly discharging into the natural receiving waters and environmental risks.A new erection method of pipe along the river adapted to the site conditions was invented to solve the problem of inconvenient construction.In addition,a new energy dissipation plate was innovatively applied to optimize the traditional energy dissipation well and effectively solve the downstream pipeline overflow problem.
