摘　　要： 为解决北方城市缺水问题,以阜新北方花园小区雨水收集和利用工程为研究对象,对小区雨水利用可行性进行分析,推荐了适合建筑小区雨水利用的工艺流程,并对主体构筑物进行了设计.同时,模拟雨水生产工艺的混合搅拌条件,对影响混凝效果的因素进行了研究,并进行了中试试验及技术经济分析.结果表明:710混凝剂效果最好,最佳投药量20 mg/L,最佳pH为7～9.中试出水水质达到相关标准,经济性较好.研究结果为北方缺水型城市住宅小区雨水利用提供可靠参考依据. In order to solve the issue of water shortage in the cities of northern China,taking the rainwater collection and utilization of Beifang Garden district in Fuxin as an example,the feasibility of rainwater utilization are analyzed and the adaptive technological process is recommended.According to the selection,the rainwater utilization engineering for the sub-district was designed and the technical design parameters were achieved.Meanwhile,simulating the mixture and stir conditions of rainwater production technology and the factors influencing coagulation effect are researched.Then the medium-test experiment and technical and economic analysis were completed.The result of the coagulation experiments shows that coagulant 710 has optimum effects and its dosage is 20mg/L,corresponding to pH values of 7 ～ 9.The effluent quality of the medium-test experiment can meet the correlated national standard and the treatment technology has better economy.This study offered a comparatively reliable reference data for construction of rainwater utilization engineer of building district in water shortage of cities in northern China.
