Description

technical field [0001] The invention belongs to the technical field of improving the quality and efficiency of urban sewage, and particularly relates to a quantitative simulation technology method for constructing a sewage collection system based on MIKE+. Background technique [0002] The urban sewage collection pipe network system is a large-scale and complex network system, including sewage pipe network, combined pipe network and other drainage systems of different systems. A perfect urban sewage collection system is a necessary condition for high-efficiency and high-quality urban operation. However, due to the traditional urban development model of "focusing on the ground and ignoring the underground", the construction of the urban sewage collection system is backward and the debt is serious, which not only causes a series of water environment problems such as frequent urban waterlogging, black and odorous water bodies, and eutrophication of water bodies, but also As a r...

However, due to the traditional urban development model of "emphasizing the ground and ignoring the underground", the construction of the urban sewage collection system is backward and the debts are serious. Leading to poor operation efficiency of urban sewage domestic sewage collection and treatment facilities

[0003] At present, most of the technical schemes for improving the quality and efficiency of sewage surrounding the urban sewage collection pipe network system are based on the traditional constant flow hydraulic calculation method or engineering experience to determine the design scheme of the sewage collection pipe network, and do not use numerical simulation software to quantitatively simulate and analyze the improvement of sewage quality. The target accessibility of the efficiency improvement scheme, and the optimization of the sewage quality improvement and efficiency enhancement scheme may eventually lead to the inaccessibility of the sewage quality improvement and efficiency assessment target, or the sewage quality improvement and efficiency enhancement engineering measures are too conservative and do not meet the technical requirements. Economic optimization requirements make it difficult to improve the operating efficiency of sewage collection and treatment facilities
