Description
Technical Field
The invention relates to a municipal drainage system, in particular to a municipal drainage system for a sponge city.
Background
The sponge city is a brand new city development concept proposed internationally at present. The sponge city is compared with the city construction as the name implies, hope that under the condition of strong rainfall climate such as rainstorm, the city can be transformed into a large sponge with extremely strong water absorption capacity, a large amount of rainwater resources are fully collected and utilized, then purification and secondary treatment of the rainwater resources are realized by applying a series of modern scientific and technical means, and necessary water is provided for city greening, road cleaning and the like. Therefore under the 'sponge city' theory, municipal drainage engineering needs to be changed into the comprehensive drainage engineering integrating the functions of penetration, water storage, purification, water utilization and drainage from the past rapid drainage and the nearby drainage, so that the city can rapidly show the 'sponge' function under the weather conditions of strong rainfall and the like, and then the problems of waterlogging, rainwater runoff pollution and the like in the city are effectively prevented.
In municipal drainage works in "sponge cities", initial rain pollution is an important problem to be dealt with. When rainfall occurs, pollutants are deposited when the rainfall impacts the ground surface, and a large amount of pollutants are contained in initial rainwater due to the influence of various precipitates and organic wastes, the pollution degree of the pollutants even exceeds that of urban sewage, and the pollutants pose a serious threat to the urban ecological environment. As rainfall increases over time, the contaminant concentration gradually decreases and eventually remains in a lower concentration range. The drainage system of the city can be optimized by applying the sponge city concept, so that the initial rainwater and the subsequent rainwater are subjected to shunting treatment.
Different areas in a city are polluted to different degrees, and areas with higher pollution degrees exist, such as roads, bridges, factories, parking lots, garbage dumps, industrial parks and the like, are influenced by traffic activities and losses of vehicles, automobile exhaust, solid waste, industrial sewage, polluted particulate matters and the like, and have larger pollution in early rain in rainfall; there are also areas with a low degree of pollution, such as parks, greenbelts, squares, etc., which are subject to a low degree of pollution and which are subject to a low degree of pollution from the initial rain during rainfall. In the prior art, after the initial rainwater is treated by shunting the rainwater to a storage well, the initial rainwater is conveyed to a sewage treatment plant through an independent sewage treatment pipeline for treatment, however, two sets of pipelines are required to be arranged in the method, the construction difficulty is high, and meanwhile, the treatment burden of the sewage treatment plant can be increased by conveying the initial rainwater in the area with low pollution degree to the sewage treatment plant. In order to solve the above problems, an improved municipal drainage system has been proposed in the prior art, in which a sewage treatment line is provided only in an area with a high degree of pollution, initial rainwater in the area is delivered to a sewage treatment plant through the sewage treatment line, and in which no sewage treatment line is provided in an area with a low degree of pollution, all rainwater in the area is discharged to a river through the municipal drainage line or stored for irrigation in green, thereby reducing the difficulty of pipeline construction and the burden of the sewage treatment plant. However, higher initial rain pollution may also occur in areas with lower levels of pollution, for example, where the precipitation concentration of pollutants increases at longer intervals during the rain cycle, resulting in higher initial rain pollution levels in areas with lower levels of pollution, and discharge of such initial rain into rivers or for irrigation poses a threat to the urban ecological environment.
