K市某给水工程初步设计(含CAD图)(任务书,开题报告,论文计算书21000字,CAD图11张)
摘要：
随着人口增长、经济发展及人类生活水平的提高，人类对水的需求日益增长，对水质、水量的要求越来越高。
本设计为K市给水工程初步设计。
水源采用地表水，取水方式：岸边合建式取水构筑物取水。
净水厂规划产水能力15万吨/天。净水工艺流程为：原水→取水泵站→管式混合器→往复式隔板絮凝池→平流沉淀池→生物接触氧化池→V型滤池→液氯消毒→清水池→送水泵站→城市管网。根据原水水质及水温，絮凝剂选用碱式氯化铝，最高投药量为16.4mg/L。选液氯消毒剂，采用滤后加氯，最大加氯量为3.0mg/L。水厂绿化面积占水厂总面积的35%。出水水质符合《生活饮用水卫生标准》（GB5749-2006）。
关键词：岸边式取水构筑物；往复式隔板絮凝池；平流沉淀池；V型滤池
Absteract：
With the population growth, economic development and the improving of living standards , human not only demands for more and more water, but also increases their demands on water quality .
    This design is about the water supply project for the K area of China which called city.

According to the original information, the raw water comes from the surface water by the type of semi-underground-shore.
The Design-scale of the water purification plants is about 150000 t/d,Process for the water purification: raw water →first pumping station →tube type mixer→Reciprocating baffled flocculation tank → stratospheric sedimentation tanks →Biological contact oxidation pond→V-filterBiological contact oxidation pondclearwell →secondary pumping station → Pipeline Network of city. According to the original water water quality andthe water temperature, Flocculant for PAC, the maximum dosage of 16.4 mg/L. Chooses the liquid chlorine disinfectant, after filtration chlorination design uses 3.0mg/L. Waterworks total area of green plants total area of 35%. Waterworks water quality conforms to the "standard of drinking water" requirement.
According to the distribution of users and the water quality, the water supply networks for the city using the way of district water supply.Both the water quality, According to the design results, all of the water Pressure,water quality and water storage can meet the uses’demands. （GB5749-2006） [版权所有：http://think58.com]
