Description
Technical field
The present invention relates to a kind of subsurface stormwater/sewage network, specifically the administering method of a kind of subsurface stormwater/sewage network bad air and facility for prevention and control.
Background technology
Subsurface stormwater/sewage network is the sewage in a city, the exhaust system of rainwater, is the basic constituent element of a city function, is also an important component part in city.The operating condition of subsurface stormwater/sewage network is directly connected to ecological environment and the city image in a city, directly affects the daily life of townsfolk.By the sewage that subsurface stormwater/sewage network is collected, carry out qualified discharge after treatment, the unrest of sewage can be avoided to arrange and leave about, thus the protection living environment of townsfolk and the healthy of townsfolk.
Subsurface stormwater/sewage network generally comprises Trunk Line, by-pass line and is connected to the microtubule line of each biotope, office, factories and miness, office premises and commercial building etc., the grid-connected connection of these Trunk Lines, service main and microtubule line, constitutes the rainwater/waste pipe network system of organic connections.Along with the increase year by year of urban construction area, the setting area of subsurface stormwater/sewage network is also just increasing; And the continuous precipitation of dirt and fermentation in rainwater/sewage network, will gather more and more rancid, the bad air that goes mouldy in rainwater/sewage network, these bad airs can be gushed out by the well lid of the rain perforaled strainer of both sides, street, the manhole even floor drain of every household.These bad airs had both caused the deterioration of urban air environment, also can bring harmful effect to health, even also can cause unnecessaryly firing event when concentration transfinites, and brought serious potential safety hazard to the life security of townsfolk.
Pure and fresh at rural area air, dirty at urban air, to the air quality in city, society is summed up as vehicle exhaust and industrial discharge, and the various bad airs of subsurface stormwater/sewage network inner accumulated and generation, discharged all the time by thousands of of city sewage draining exit (floor drain etc. of the sewage draining exit that urban road limit is arranged, well lid, community sewage manhole cover, premises).
We find, city is just after a torrential rain, and the streets and lanes in whole city are all in traffic congestion, car is in exhaust, and air is pure and fresh, because row's rain, subsurface stormwater/sewage network has a large amount of storm-water drainage, water is in flow process, taken away by bad airs a large amount of in pipe network, the dirty gas in subsurface stormwater/sewage network no longer upwards distributes, and fills the air whole city, like this, the air in city just can pure and fresh several days.Along with creating again dirty gas and distributing outwardly in subsurface stormwater/sewage network, city is shrouded again in dirty gas.
The a large amount of dirty pernicious gas that subsurface stormwater/sewage network produces is producing always, is distributing always, be that one is stealthy to townsfolk to injure and chronic killer, because the event of hurting sb.'s feelings that pernicious gas dirty in subsurface stormwater/sewage network causes, and to produce due to bad air in subsurface stormwater/sewage network fire event, all happen occasionally.Up to now, each city does not also all have a kind of effective process means for the bad air of subsurface stormwater/sewage network.
