Description
Technical field
The invention belongs to sponge urban construction fields, in particular to rainwater purification recycling biological gaseous-waste holdup system.
Background technique
The fast development of urbanization has been directly changed the property and morphological feature of underlying surface, so that runoff pollution adds
Play carries a large amount of pollutant (suspended matter, nitrogen, phosphorus etc.) in runoff, thus caused a series of Urban Water Environment problem,
The wherein water eutrophication of city river and black smelly particularly problematic.It is a kind of widely used low shadow that biology, which is detained facility,
Ring development facility, can effectively from source reduction and control Runoff contaminants migration, biology be detained facility mainly utilize plant,
The collective effect of filler and microorganism removes Runoff contaminants by physics, chemistry and biological respinse, to reach purified water
The function of matter.Wherein, filler is the key factor to purify water, and only plant growth does not provide good environment, while being micro-
The growth and breeding of biology provide the environment adapted to, and the component in filler can also directly be removed in runoff by physics chemical action
Pollutant.At present it is most of biology be detained facilities be divided into coating, planting soil layer, geotextile layer, packing layer, geotextile layer,
Supporting layer and drainage blanket are layered more, operation and maintenance cost height；In addition, the low water outlet for influencing development facility is by facility bottom
The limitation of 1m need to be greater than apart from underground water highest dynamic water level, do not allow directly lower infiltration generally, unified heel row of collecting is needed to enter municipal administration
Drainage pipeline networks.Therefore, biology is detained facility and need to be further improved.
