Description
Technical Field
The invention belongs to the technical field of environmental protection, and particularly relates to a split-flow system for controlling sewage and initial 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.
When the existing combined drainage system is used for intercepting a natural rainwater flow, the intercepting times are not enough, so that the intercepting well cannot intercept surface source pollutants, the surface source pollutants directly enter a natural water body and pollute the natural water body, ② if the surface source pollutants are controlled, the size of the intercepting well is increased, the capacity of a sewage plant is increased, the interception of the intercepting well is controlled in a coarse mode, the initial rainwater cannot be accurately intercepted, the split drainage system is divided into two drainage systems of a complete split drainage system and an incomplete split drainage system according to different rainwater removal modes, the complete split drainage system is used for completely separating rainwater from sewage, industrial sewage, the rainwater is conveyed by different pipelines, the sewage discharged by residents enters a sewage main sewage pipe, and then is conveyed to a sewage water main pipeline after the sewage water enters a sewage treatment area, the sewage water main pipeline enters a sewage drainage balcony, the sewage water main pipeline is conveyed to a sewage water drainage area, the sewage water drainage system is used for directly, the sewage water drainage system for intercepting the natural rainwater and the sewage, the rainwater enters a sewage water drainage pipeline for the natural rainwater, the sewage is conveyed by a sewage treatment area, the sewage water drainage pipeline, the sewage water main sewage water drainage system is also used for collecting sewage, the sewage water drainage pipeline for the natural rainwater, the sewage is divided sewage water drainage pipeline for the natural rainwater drainage system for collecting sewage, the natural rainwater drainage pipeline for the natural rainwater drainage system for the natural rainwater drainage of the natural rainwater drainage, the natural rainwater drainage pipeline for the natural rainwater drainage system is divided sewage, the natural rainwater drainage pipeline for the natural rainwater drainage of the natural intercepting well, the natural intercepting pipeline for the sewage drainage of the natural intercepting well, the sewage drainage of the natural intercepting well, the sewage drainage of the rainwater drainage of the sewage drainage of the natural intercepting well, the sewage drainage of the natural intercepting well, the sewage drainage of the natural intercepting is not used for the natural intercepting well, the sewage drainage of the natural intercepting well, the natural intercepting system is not used for the natural rainwater drainage of the sewage drainage of the natural rainwater drainage of the natural intercepting system is not used for the sewage of the natural intercepting well, the sewage of the natural intercepting, the sewage is not used for the natural intercepting well, the sewage of the natural intercepting, the sewage is not used for the natural rainwater drainage of the sewage is not used for the natural rainwater drainage of the natural intercepting well, the natural intercepting, the natural sewage of the natural intercepting well, the natural intercepting, the natural rainwater drainage of the natural rainwater drainage.
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.

The sleeve isolates the mechanical structure from contact with the soil on one hand and supports the input shaft 812 and the output shaft 814 on the other hand.
The working principle of the invention is as follows: in sunny days, the impeller 811 cannot be driven to rotate due to the fact that the flow rate in the rainwater pipeline 1 is small and the liquid level is low, so that the valve plate 831 is kept at a high position due to the action of the tension spring 841, and the second outlet 7 is in a normally open state;
when the rainfall falls, the initial rainfall water flow drives the impeller 811 to rotate so as to drive the input shaft 812 to rotate, the input shaft 812 drives the output shaft 814 to rotate through the reversing transmission mechanism 813, and then the lifting mechanism 82 drives the valve plate 831 to descend, the process is a continuous process and is not a transient process, the process that the valve plate 831 descends until the second outlet 7 is completely closed has a certain time T, the rotating speed of the impeller 811 is basically unchanged, so that the mechanical transmission ratio of the dynamic power transmission mechanism 81 and the lifting mechanism 82 can be changed to adjust the time T, the second outlet 7 is still in an open state within the time T, the initial rainfall at the initial rainfall period is discharged into the sewage pipeline 2 from the second outlet 7, the natural water body is prevented from being polluted, the diversion of the rainfall is realized, the second outlet 7 is closed after the time T, and the rainwater is discharged into the natural water body from the first outlet 6.
Even if the impeller 811 rotates due to the ground cleaning, the second outlet 7 is not closed because the drainage time is short due to the ground cleaning, and therefore, the sewage from the ground cleaning is discharged into the sewage port through the second outlet 7, which does not cause the problem that the ground cleaning water is mistakenly discharged into the natural water body.

When the liquid level in the shunt well 4 descends in sunny days, the floating ball 857 and the pawl 852 are driven to descend to be separated from the ratchet 851, the unidirectional limiting of the ratchet 851 is relieved, and the tension spring 841 can drive the valve plate 831 to reset to reopen the second outlet 7.
A spring 853 is provided at the bottom of the pawl 852 and the spring 853 is capable of maintaining the engagement of the pawl 852 with the ratchet 851 to prevent gravity from causing the pawl 852 to fail to engage the ratchet 851.
