Embodiment Construction

[0015] The patent of the present invention proposes an optimal design method for drainage partitions of rural domestic sewage treatment projects based on the combination of CAD engineering drawing software and various calculation tools such as Excel, Matlab, and VB. According to the design method of the present invention, the drainage zoning optimization of rural domestic sewage treatment projects includes engineering design and cost calculation, which is further divided into four steps: drainage zoning scheme design, pipeline engineering design, sewage treatment station design and scheme comparison.

[0016] (1) Drainage zoning scheme design: According to the actual living conditions of rural residents, the drainage zoning is divided according to the single household (joint household), the district to the whole village collection mode. For example, for a central village with a population of 10,000, the drainage zones are divided according to the drainage scales of 50, 100, 200...

Abstract

The invention relates to a drainage partition optimized design method of a rural life sewage treatment project, and provides a design method based on combination of sewage treatment project design and cost calculating comparison. The sewage treatment project design includes that according to rural peasant household residence distribution conditions, drainage partition division with different scattering degrees is carried out, and sewage pipelines and sewage treatment farms (stations) are respectively designed. The cost calculating comparison includes that assessment software is written by means of a visual basic (VB) platform, building cost and operational maintenance cost of drainage pipelines and sewage treatment facilities in different drainage partition schemes and treatment total cost of water per ton after the two preceding parts of cost are added together are calculated, and then the drainage partition dividing method of the rural life sewage treatment project at least treatment cost is obtained by comparison. By means of a drawing function of an EXCEL working sheet, sewage treatment cost of different drainage partition schemes is visually displayed. According to the drainage partition-cost assessment system developed in the method, the rural life sewage treatment design project can be optimized.

Description

Technical field [0001] The patent of the present invention is based on the drainage partition optimization design method of rural distributed domestic sewage treatment projects, and is applicable to the field of planning and design of rural domestic sewage treatment projects. Background technique [0002] Due to the scattered living of rural residents, rural domestic sewage has the characteristics of small water volume and large coefficient of variation, which also leads to low efficiency of rural domestic sewage pipeline collection. At the same time, for the design of small-scale domestic sewage treatment facilities, our country is still in the stage of exploration and practice, and the cost relationship that varies with the scale of treatment is still unclear. Therefore, the design of rural domestic sewage treatment projects cannot completely copy the urban centralized treatment model, but should be based on the distribution of farmer households in villages, on the premise...
