Description
Technical Field
The patent of the utility model relates to a system of damming based on wisdom thing networking adjustable damming multiple and control method thereof belongs to municipal drainage facility technical field in city.
Background
In China, with the increase of urban population and the development of industrial and agricultural production, the sewage discharge amount is increasing day by day, the water body pollution is quite serious, and the water body pollution is almost spread all over the country. Therefore, in order to reduce the sewage treatment pressure, the sewage interception, diversion and reconstruction strength of governments in various regions on urban and rural rainwater and sewage converging pipelines is continuously increased. At present, the most direct and fast-acting mode for the confluence pipe is to build a new intercepting well, and the intercepting well is an important structure in a municipal drainage system, can collect direct-drainage sewage in dry weather and reduce overflow pollution in rainy days. In dry weather, intercepting the sewage along the river drainage port and entering a sewage treatment plant; in rainy days, part of the mixed rain-sewage flow is cut off and enters a sewage treatment plant, and the mixed rain-sewage flow exceeding the cut-off capacity is discharged into surface water.
Traditional vatch basin has slot type, weir formula and groove weir convolution, has following not enough: 1) the designed shutoff amount is greatly different from the objectively required shutoff amount. The design intercepting flow is determined by taking measures such as certain research and theoretical calculation, setting different heights of overflow weirs and the like; the flow intercepting amount required objectively is determined according to the actual condition of confluence and mixed flow of each discharge opening, the overflow pollution control requirement and the capacity of the urban sewage treatment system. The difference between the two is large, and once the height of the overflow weir is set, the height of the overflow weir is difficult to adjust. 2) Draining stagnant water and blocking water. The design rule requires that the top of the overflow weir is higher than the flood level of the river channel to prevent the river water from flowing backwards, which tends to form unsmooth drainage. 3) The interception efficiency is low. In the drainage system, a plurality of intercepting wells are usually connected in series by an intercepting main pipe, the water intercepted by the previous well is mixed with the water before intercepting the next well and then intercepted, and the mixed water is diluted step by step and finally enters the sewage system with low water concentration. 4) The deposition contamination is severe. Most of the cut-off water is surface water, the deposition and pollution of pipes and wells are serious, and the cut-off water is finally flushed into a river along with rainstorm to influence the urban water environment.
At present, a combined sewage pipe network system is mostly adopted in old urban areas, and when the rainwater and sewage diversion transformation is not thoroughly carried out, more intercepting wells are inevitably required to be newly built, so that the sewage is effectively intercepted, and the pollution to a river channel is avoided. However, most of newly-built intercepting wells cannot adjust the intercepting multiple, so that more sewage rainwater enters a sewage pipe network system in a rainstorm period, and then the water inflow of a sewage treatment plant is exploded, and the design scale is far larger. Therefore, an intelligent intercepting well needs to be constructed, the intelligent intercepting well can be adjusted automatically to deal with different working conditions so as to avoid excessive rainwater which basically does not contain pollutants in water quality being intercepted and entering a sewage pipe network system.
