Embodiment 1
[0025] This embodiment provides a method for dynamic load balancing of urban sewage treatment pipe network:
[0026] Such as figure 1 as shown,
[0027] In the urban pipe network lay the pipe network flowing to the two sewage plants.
[0028] The sewage pipe network coming out of urban sewage production areas A1 and A2 is connected with the main pipe network flowing to the sewage treatment plant.
[0029] In the above-mentioned pipe network docking interface, the regulating valves B1 and B2 are installed. The regulating valves B1 and B2 have network communication functions, and can dynamically control the amount of water flowing into different pipes according to the instructions of the remote control center.
[0030] Water flow monitoring sensors D1 and D2 with network communication function are installed in the sewage treatment plant, and relevant detection data are aggregated and transmitted to the control center.
[0031] The control center detects in real time the amoun...
Embodiment 2
[0038] Such as figure 1 As shown, this embodiment involves four part definitions:
[0039] Urban sewage area: Urban sewage areas A1 and A2 in the figure are places where a city provides sewage, such as living areas, industrial areas, etc., and a lot of sewage is produced every day. In this embodiment, in order to simplify the model, two water plants are set, but there may be more in practice.
[0040] Sewage treatment plant: The sewage treatment plants C1 and C2 are used for sewage treatment. In this patent, for the sake of simplification, the treatment of domestic sewage and industrial sewage is no longer distinguished. When the sewage treatment plant is under construction, there is a maximum daily sewage treatment volume. If this volume is exceeded, the sewage treatment plant will enter a saturated state, the equipment will be more prone to aging, and the insufficient treatment capacity will cause the treated sewage to fail to meet the standard. Therefore, in production an...
Embodiment 3
[0052] On the basis of Example 1, when the sum of the maximum daily sewage treatment capacity of each sewage treatment plant is less than the daily sewage flow in the sewage pipe network, control Z 1 :Z 2 :……Z n =Max 1 : Max 2 : ...Max n .
[0053] In this embodiment, when the amount of sewage exceeds the sum of the maximum daily sewage treatment capacity of each sewage treatment plant, the distribution ratio of sewage is allocated according to the proportion of the maximum daily sewage treatment capacity of each sewage treatment plant, so that each sewage The degree of overloading of treatment plants is the same, which can avoid the problems of equipment damage or unsatisfactory treatment effect due to excessive overloading of a certain sewage treatment plant.

Abstract
The invention discloses a method for urban sewage treatment pipe network dynamic load balancing. The method comprises the steps of (1) determining the daily maximum sewage treatment amount Max1, Max2,...Maxn of each sewage treatment plant; (2) distributing sewage daily flowing amount X in a sewage pipe network to each sewage treatmentplant, wherein Z1, Z2,...Zn respectively represent the sewage treatment percent of each sewage treatmentplant, and Z1+Z2+...Zn is equal to 100 percent; (3) calculating the current sewage daily flowing amount ZiX of each sewage treatment plant, wherein i is larger than or equal to 1, and less than or equal to n; (4) comparing the current sewage daily flowing amount ZiX of each sewage treatment plant with the maximum sewage treatment amount Maxi, when the current sewage daily flowing amount ZiX of m sewage treatment plants is larger than the maximum sewage treatment amount Maxi, controlling the Zi of the m sewage treatment plants to be reduced, so as to enable the current sewage daily flowing amount ZiX to be equal to the maximum sewage treatment amount Maxi, and controlling the Zi of the other n-m sewage treatment plants to be increased, controlling the sum of the sewage daily flowing amount of all the sewage treatment plants to be equal to the sewage daily flowing amount of the sewage pipe network, and returning back to step (3), wherein m is less than or equal to n.
Description
technical field [0001] The invention relates to a method and system for dynamic load balancing of urban sewage treatment pipe network. Background technique [0002] In the process of urban sewage treatment, several sewage treatment plants are generally established to treat domestic and industrial sewage in the city. Urban domestic and industrial sewage flows into various sewage treatment plants through the city's municipal sewage pipe network. Since the sewage treatment plants are distributed around the city, the situation of domestic and industrial sewage around each sewage treatment plant is different, some have a lot of sewage, and some have a small amount of sewage. Due to the uncontrolled flow of sewage in the pipelines, some sewage treatment plants will be oversaturated and exceed their own output capacity; some sewage treatment plants will not have enough treatment capacity and their equipment will be left idle. Contents of the invention [0003] In view of the ab...
