Description

Cut transformation structure of dirty box culvert vatch basin

Technical Field

The utility model relates to a drainage technology field, concretely relates to cut dirty box culvert vatch basin's transformation structure.

Background

Along with the rapid development of cities, the water quality of riverways is deteriorated and the black and odorous condition is increasingly serious due to a combined drainage mode. In recent years, treatment of black and odorous water bodies achieves remarkable effect all over the country, source control and sewage interception are taken as one of the most important treatment measures, a large number of engineering examples are adopted, intercepting wells and sewage interception pipe culverts-large interception and drainage systems are arranged on the riverway coasts, and a mixed flow port and a sewage port along the riverway are all connected into the sewage interception pipe culverts, so that sewage cannot enter the river in sunny days, and the water quality reaches the standard in sunny days. However, the problem of rain and sewage caused by the large intercepting and draining system is that the inflow water volume of the sewage plant is increased rapidly in rainy seasons, the inflow water concentration is low, the treatment efficiency of the sewage treatment plant is affected, and the impact on the sludge of the plant is easy to cause. Meanwhile, due to the fact that the plant station processing capacity is effective, the problems of combined system overflow pollution and the like are caused, rain and sewage are discharged into a river in a mixed mode, and the river channel environment is seriously impacted.

Therefore, some cities begin to develop comprehensive black elimination, just this clear source etc. and carry out thorough distribution of rain and sewage from the source gradually, will directly discharge the sewer pipe and insert municipal sewer nearby, peel off the sewage in the mixed flow pipe culvert in the current situation upper reaches and become the rainwater pipe culvert, consequently intercept dirty box culvert and define as first rain box culvert to realize that real meaningful sewage does not go into the river. However, the following problems are encountered in practical engineering: 1. the problem of accurate interception of the initial rain; 2. the problem of clear water peeling off, the current situation upper reaches rainwater canal conflicts with the elevation of intercepting box culvert, and when clear water peeling off, the upper reaches rainwater passageway is blocked by intercepting box culvert. When the initial rain sewage interception port in the intercepting well is closed, the water level rises, and the upstream area is caused to waterlog; 3. the problem of sewage backflow in the sewage intercepting box culvert results in long-term black and odorous open channels of upstream rainwater pipe culverts; meanwhile, the landscape requirements of the shoreline of some urban river channels require that the upper part of the intercepting well is modified to meet the requirements of beauty and safety. Therefore, higher requirements are required for the reconstruction of the sewage interception box culvert intercepting well.
