Description
Technical Field
The utility model relates to a reposition of redundant personnel system drain pipe network system belongs to distributed source first face pollution control technical field, concretely relates to reposition of redundant personnel system drain pipe network system of control sewage and initial stage rainwater pollution.
Background
Urban municipal drainage systems are mainly divided into combined drainage systems and split drainage systems. The earliest combined drainage system mixes sewage, industrial wastewater and rainwater in the same canal, and directly discharges the sewage, industrial wastewater and rainwater into a water body nearby without any treatment, so that the received water body suffers from serious pollution, and the mode is almost adopted in many old cities at home and abroad. A shut-off type combined flow drainage system is now commonly used.
The intercepting type combined drainage system is basically identical in structure to a conventional combined drainage system, and is different from the intercepting type combined drainage system in that a intercepting well is arranged between a municipal combined main pipe and a sewage treatment plant. During the work of the shutoff type combined drainage system, sewage discharged by residents and rainwater collected by rainwater openings all enter the municipal combined main pipe through the combined pipeline, rainwater collected by the rainwater openings along the municipal road also enters the municipal combined main pipe, and a shutoff well is arranged at the tail end of the main pipe. In sunny days, all sewage is conveyed to a sewage plant and is discharged to natural water after being treated. During rainfall, sewage and rainwater in the early stage of rainfall are also conveyed to a sewage plant, and are discharged to a natural water body after being treated. However, with the increase of rainfall, the runoff of rainwater also increases, and when the flow of the mixed sewage exceeds the water delivery capacity of the intercepting main pipe, part of the mixed sewage overflows and directly enters the natural water body.
the combined drainage system mainly solves the problems that a residential area and a municipal road can produce non-point source pollution when raining, although an ③ intercepting well is arranged at the tail end of the existing combined drainage system for ③ intercepting, the designed ③ intercepting multiple is not enough, so that the ③ intercepting well can not intercept the non-point source pollutants, the non-point source pollutants directly enter a natural water body and pollute the natural water body, and if the non-point source pollutants are to be controlled, the size of the ③ intercepting well needs to be increased, the size of an ③ intercepting main pipe needs to be increased, the capacity of a sewage plant is increased, the ③ intercepting of the ③ intercepting well is controlled in a rough mode, and initial rainwater can not be accurately intercepted.
the split-flow drainage system is divided into a complete split-flow drainage system and an incomplete split-flow drainage system according to different rainwater removal modes, wherein the complete split-flow drainage system completely separates rainwater from sewage and industrial sewage and conveys the sewage through different pipelines, sewage discharged by residents enters a sewage main pipe through a sewage pipeline and is conveyed to a sewage plant for treatment and then is discharged, rainwater collected by a rainwater inlet enters the rainwater main pipe through a rainwater pipeline and is directly discharged to a natural water body, rainwater collected by the rainwater inlet along a municipal road also enters the rainwater main pipe and is directly discharged to the natural water body.
the sewage discharged by residents and the rainwater collected by a rainwater port are discharged through a confluence pipeline, a cutoff well is arranged before the sewage enters a municipal drainage pipeline for cutoff, the rainwater collected by the rainwater port along the municipal road enters a rainwater main pipe and is directly discharged to a natural water body, in fine days, the sewage discharged by the residential area and the rainwater at the initial stage of rainfall are cut off to the rainwater main pipe and then are conveyed to a sewage plant, the sewage is discharged to the natural water body after treatment, but partial sewage on the municipal road enters the rainwater main pipe and is directly discharged to the natural water body, in the case of fine days, the sewage discharged by the residential area and the rainwater at the initial stage of rainfall are also cut off to the rainwater main pipe and then are conveyed to the sewage plant, the rainwater runoff is increased along with the increase of rainfall, when the flow of the mixed sewage exceeds the water conveying capacity of the cutoff pipeline, partial mixed sewage overflows and directly enters the rainwater main pipe and is not capable of controlling the rainwater at the initial stage, and the rainwater cannot enter a sewage plant to control the rainwater system at the initial stage.
In general, the current drainage system has the following problems: first, control of surface source contamination is not possible; secondly, the control is extensive, and the sewage and initial rainwater cannot be accurately controlled; thirdly, the pipelines are connected in a mixed mode, and sewage is directly discharged to a natural water body; fourth, for areas with tight land, end management cannot be effectively implemented.
The invention discloses a Chinese invention patent with the publication number of CN105625545A and the invention name of 'a regional fragmented rainwater treatment system based on a shunt pipe network', and provides a new pipe network division method to solve the problems. According to the application, the whole pipe network is divided into a plurality of latticed areas according to the area, an independent online rainwater treatment facility is arranged in each area, and rainwater in the areas is comprehensively treated through the online rainwater treatment facilities in the areas. However, after a large number of experiments, the inventor finds that the tail end treatment thought improves the rainwater treatment efficiency and degree in the corresponding area to a certain extent, and controls the non-point source pollution in the area; however, the problem that surface runoff collection is difficult to control accurately still exists, and the time difference exists between the collection of the initial rain at the farthest end and the nearest end of the online rainwater treatment facility, and the collection of the initial rain and surface source pollution cannot be controlled accurately, so that accurate management cannot be achieved. In addition, due to the problem of urban planning, the division of the urban pipe network into grid-shaped areas has a lot of interferences and very high implementation difficulty, which causes great troubles to the urban pipe network arrangement mode of the mode.
Meanwhile, the existing regional treatment technology has the following problems that the division is carried out based on the geographical position, and facilities with different purposes such as industry, residential districts, schools and the like are not considered to be divided into the same region, so that the sewage in the region has complex components, high difficulty in accurate treatment and separation and higher cost.

When the rainfall intensity is high, when the first primary rain regulation and storage tank C reaches the highest water storage level, the lower opening type weir gate 9 is in an open state, and rainwater directly enters the rainwater trunk pipe B-2 through the rainwater pipeline A-2 and then is directly discharged to a natural water body.
For the municipal road area B, when rainfall is small, the lower opening weir gate 9 on the rainwater trunk pipe B-2 is in a closed state, initial rainwater entering the rainwater trunk pipe B-2 enters the sewage trunk pipe through the buffer tank of the second primary rainwater storage tank D, and the total amount of the initial rainwater is determined by the treatment capacity of a sewage plant and is conveyed to the sewage plant for treatment. Along with the increase of rainfall, if the rainfall exceeds the treatment capacity of the sewage plant, the rainwater enters the second primary rainwater storage tank D for storage, and enters the sewage plant for treatment when the weather is fine.
When the rainfall intensity is high, when the second primary rain regulation and storage tank D reaches the highest water storage level, the lower opening weir gate 9 positioned on the rainwater trunk pipe B-2 is in an open state, and rainwater is directly discharged to a natural water body after entering the rainwater trunk pipe B-2.
The embodiment of the utility model provides a second theory of operation as follows: for the unit area A, when the weather is fine, sewage discharged from the unit area A enters the sewage main pipe B-1 through the sewage pipeline A-1, and then is conveyed to a sewage plant for treatment and then is discharged.
When rainfall is small, sewage discharged from the unit area A still enters the sewage main pipe B-1 through the sewage pipeline A-1 and is then conveyed to a sewage plant for treatment and then discharged, the downward-opening weir gate 9 is opened, and initial rainwater enters the rainwater pretreatment system for treatment and then is discharged to a natural water body.
When the rainfall intensity is high, the downward opening weir gate 9 is closed, and the rainwater in the middle and later periods is directly discharged to the natural water body after passing through the rainwater pipeline A-2.
For the municipal road area B, when rainfall is small, the downward-opening weir gate 9 is opened, and rainwater in the rainwater trunk pipe enters the rainwater pretreatment system to be treated and then is discharged to a natural water body.
When the rainfall intensity is high, the rainfall intensity exceeds the processing capacity of the rainwater pretreatment system, so the downward opening weir gate 9 is closed, and the rainwater in the middle and later periods is directly discharged to a natural water body after passing through the rainwater trunk pipe B-2.
