【摘要】：水资源是人类生存与发展的重要资源,涉及到国家及城市的发展建设。河北省会石家庄水资源问题更是日益尖锐。石家庄市是全国35个最为缺水的城市之一,人均水资源量为256立方米,仅为全国水平的1/8,属于极度缺水地区。石家庄常年大量开采地下水,造成地下水位埋深不断下降,地下水漏斗面积不断增大。寻找新的水源可以缓解地下水短缺问题。雨水是自然界水循环之中大气降水的产物,受到的污染较小,处理简单,可以作为生活杂用或工业用水。本文通过对石家庄水资源状况的分析,选择了石家庄经济学院的主校区为研究对象,对石家庄水校园雨水利用进行了分析,并结合石家庄经济学院新校区搬迁,为新校区的水资源节约与雨水的利用,提出建设性的建议。本文研究如下:1.对石家庄经济学院主校区校园环境及各类集水面情况进行了调查,并设计雨水收集方案,确定了雨水水质分析指标,改进了快速测得COD的方法。2.分析了校园雨水水质情况,发现雨水水质在降雨初期较差,在降雨后期水质逐渐变好,悬浮物含量在50mg/L左右,总磷含量在0.1mg/L左右,总氮含量15mg/L左右,COD含量100mg/L左右。实验数据对比可以得出屋面雨水比路面雨水水质好,铁皮屋面收集到的雨水水质较其他屋面好;夏季雨水水质较春季秋季雨水水质好。3.对实验数据进行回归分析,发现雨水各污染指标与悬浮物具有较好的相关性。4.通过向雨水中添加絮凝剂的方法处理雨水,经实验可知处理之后的雨水水质达到校园生活杂用水的使用标准。5.针对石家庄经济学院校园的具体情况,设计合理的校园雨水收集和利用方案,将处理之后的雨水作为校园生活杂用水。6.根据本实验数据及雨水利用方案,对石家庄经济学院新校区的建设提出雨水收集和利用的建议。
[Abstract]:Water resource is an important resource for human survival and development, which involves the development and construction of the country and city. Hebei provincial capital Shijiazhuang water resources problem is increasingly acute. Shijiazhuang is one of the 35 most water-deficient cities in China, with a per capita water resource of 256 cubic meters, which is only one eighth of the national level. In Shijiazhuang, groundwater is exploited in large quantities all the year round, which results in the decrease of groundwater table depth and the increase of groundwater funnel area. Finding new sources of water can alleviate groundwater shortages. Rain Water is the product of atmospheric precipitation in the natural water cycle. It is less polluted and easy to deal with, so it can be used as household or industrial water. Based on the analysis of water resources in Shijiazhuang, this paper chooses the main campus of Shijiazhuang School of Economics as the research object, analyzes the utilization of Rain Water in Shijiazhuang Water Campus, and combines with the relocation of the new campus of Shijiazhuang School of Economics. Some constructive suggestions are put forward for water resources conservation and Rain Water utilization in the new campus. This paper studies as follows: 1. The environment of the main campus of Shijiazhuang Institute of Economics and the situation of collecting water surface were investigated, the collection scheme of Rain Water was designed, the analysis index of Rain Water water quality was determined, and the method of rapid COD measurement was improved. The water quality of Rain Water on campus was analyzed. It was found that the water quality of Rain Water was poor in the early stage of rainfall, and gradually improved in the later stage of rainfall. The content of suspended matter was about 50mg/L, the content of total phosphorus was about 0.1mg/L, and the content of 15mg/L was about 100mg/L. The comparison of experimental data shows that the water quality of roof Rain Water is better than that of pavement Rain Water, the quality of Rain Water collected from iron roof is better than that of other roofing, and the water quality of Rain Water in summer is better than that of Rain Water in spring and autumn. By regression analysis of experimental data, it was found that each pollution index of Rain Water has a good correlation with suspended matter. 4. 4. Rain Water was treated by adding flocculant to Rain Water. The experimental results showed that the quality of Rain Water reached the standard of using miscellaneous water in campus. According to the concrete situation of Shijiazhuang School of Economics, a reasonable scheme of collecting and utilizing campus Rain Water is designed, and the Rain Water is treated as the miscellaneous water for campus life. According to the experimental data and the scheme of Rain Water utilization, the suggestions of Rain Water collection and utilization are put forward for the construction of the new campus of Shijiazhuang Institute of Economics.
