Question

随着国内城市化进程的进一步加快，给排水工程已经逐步发展成为城市建设和工业生产的重要基础设施，成为人类生命健康安全和工农业科技与生产发展的基础保障。而城市雨水污水排水工程对于城市水体环境保护和自然循环的影响更为巨大。
本次毕业设计要求对DD（1）城市进行排水系统设计，其内容包括城市雨水排水系统设计和污水排水系统设计两项内容，设计时采用分流制排水系统。
设计雨水排水系统时，首先须对城市确定两种或两种以上排水方案，并对其进行比较选择更为合理的方案。确定最优方案后，要根据各项原则，对城市进行管道布置并划分设计管段确定检查井位置，同时对管段及检查井进行编号。随后要对整个城市划分汇水面积、编号并量出其大小。然后，根据这些面积大小及相关资料得出每根管段的设计流量，通过水力计算表得出每根管段的管径、坡度以及流速等各项参数，进而得出每根管段的各项标高数据。最后，将计算所得的各项参数标于平面图中对应位置，并编写计算说明书。
对于城市的污水排水系统，同样先要对城市确定两种或两种以上的排水方案，对其进行方案比较并选择更为合理的方案。确定最优方案后，按照雨水排水系统的设计方法，并结合污水排水系统的相关资料及规范，即可计算出污水管段的各项参数。最后，将计算所得的各项参数标于平面图中对应位置，并编写计算说明书。
完成上述两项内容后，须根据具体要求，将设计成果出图，并绘制相关手绘图纸。以上即为本次毕业设计所有内容。

你好，翻译结果如下：

Give the outlet work the important infrastructure for hasing already gradually evolved to become construction in the town and industrial production along with the further quicken of local urbanization progress, become the ground wok guarantee of healthy human being's life safety and work agriculture technologies and product development.But the storm sewage sanitary sewage outlet work in town affect to the aqua corpus environmental conservation in town and natural cyclic more huge.
This graduation designs to require to steer drainage system to design to the DD(1) town, its contents including storm sewage drainage system in the town design and sanitary sewage drainage system design two contents sc and design adopt separate system drainage system.
The beard recognizes 2 kinds vs the town first while designing storm sewage drainage system or two kinds of above drain a scheme, and as to it's the undertake relatively select more rational scheme.After recognizing the superior scheme, sur each principle, steer the canal layout amalgamation curtate design length assurance inspection shaft site to the town, at the same time vs length and inspection shaft steer symbolization.Want to divide the line watershed area, symbolization to the whole town later on and mete out its dimension.Then, sur these time area concentration diagram dimension and related data get proptosis each time the design runoff of root-canal zone, pass hydraulic power work sheet proptosis each time each parameters such as tube diameter, rise and run and current velocity etc. of root-canal zone, then get a proptosis each time each true height data of root-canal zone.Ultimately, mark each parameter that the calculation gain in in the floor plan vs in response to the site, and write to compute manual.
For the urban sanitary sewage drainage system, the same first essentials recognizes 2 kinds or more than two water discharge schemes to the town, as to it's steer a scheme compare and select more rational scheme.After recognizing the superior scheme, secundum storm sewage drainage system of design procedure, and combine the related data and specification of sanitary sewage drainage system, scilicet each parameter of the calculability proptosis sanitary sewage length.Ultimately, mark each parameter that the calculation gain in in the floor plan vs in response to the site, and write to compute manual.
After terminating two above-mentioned contents s, root of whiskers according to concrete request, will design a fruit proptosis general view, and draw a related change hands design paper.It above is this graduation to design all contents sc.
Keyword:Outlet work, separate system, storm sewage drainage system, sanitary sewage drainage system.

Answer 2

With the further acceleration of domestic city procedures, water supply and drainage engineering has gradually developed into an important infrastructure for city construction and industrial production and a basic safeguard of human life health safety and the agr-industry, sci-tech and production development. Whereas it is more significant that the rain and sewage drainage engineering impacts on city environmental protection of water body and the natural circulation.

This graduation design requires DD: (1) city drainage system design including two items ----the city rain water drainage system and sewage drainage system design, used in the design of drainage system.

For the rainwater drainage system design, firstly, two or more drainage schemes are made, and more reasonable schemes are carried on and selected; after the optimal scheme determined, the pipeline layout and partition design must be made out to determine the pipe inspection well position, and numbered the pipe and the inspection well at the same time as per the regulations. Subsequently, the whole city catchment area, numbers are divided and the size measured. After that, according to the size and the related data, each pipe section of the design flow must be calculated; through hydraulic calculation table, each pipe section diameter, slope and velocity and other parameters are drawn, and therefore each pipe section of the elevation data is reached Finally, the calculated parameters are marked on a planar graph of the corresponding position, and the calculation specification is compiled.

For the city sewage drainage system, two or more kinds of drainage schemes are determined, the scheme comparison and a more reasonable scheme selection are needed; after the optimal scheme determined, according to the system design methods for rainwater drainage and the combination of sewage drainage system, relevant information and specification, the parameters of the sewage pipe can be calculated; finally, the calculated parameters are marked on a planar graph of the corresponding position, and the preparation of calculation specification is compiled..

After the completion of the two projects, as the specific requirements, the design results must be mapped out and related drawings must be hand-drawn.
The graduation design contents all above

Key words: drainage, shunt system, drainage system, sewage drainage system.
