(4) charcoal packing layer includes charcoal filler device 4 and charcoal improvement soil；Charcoal filler device 4 makes for cement material, and pressure-bearing, voltage endurance capability are good, safe and reliable.Specification is: length × width × height=50cm × 50cm × 60cm, and wall thickness is 3～5cm；Uniformly opening 12 permeable circular holes 15 each of charcoal filler device 4, permeable circular hole (15) a diameter of 8～10cm, the adjacent circular hole heart is away from for 15cm；Charcoal 42.2 ± 8.1kg is filled in charcoal filler device (4)；Simultaneously for preventing charcoal granule from spilling from permeable circular hole 15, one layer of geotextiles 10 of surrounding place mat inside charcoal filler device 4；Charcoal filler device 4 is spaced with the charcoal improvement soil that thickness is 5～10cm；
(5) charcoal packing layer is separated by by geotextiles 10 with vegetation plantation soil layer 9；
(6) at charcoal improvement soil (volume ratio, soil: charcoal=9:1 are sufficiently mixed) that vegetation plantation soil layer 9 laying depth is 20～30cm, on the one hand the soil after improvement be prone to rainwater infiltration, be on the other hand beneficial to the growth of plant；
(7) uniformly lay the gravel mulch layer 8 of 3～5cm thickness at vegetation plantation soil layer 9, play the effect of buffering rainwater.
This utility model utilizes the absorption of plant, soil and charcoal and detergent power that rainwater is carried out integrated treatment, and its process is:
When rainwater flows to biological delaying basin 3, first contact with opening vertical curb band 2 and gravel mulch layer 8, bigger material is intercepted, rainwater infiltration obtains preliminary purification through vegetation plantation soil layer 9 subsequently, through geotextiles 10, continue on through charcoal packing layer 4, accumulated up hill and dale and purified, rainwater after charcoal packing layer enters in the water-retention well 7 of both sides by gravel drainage blanket 11, and the construction specification of water-retention well 7 and quantity should determine according to the long-term rainfall in locality or flow path surface and the construction scale of biological delaying basin 3.Rainwater after purification can be used for spraying road surface, plant and cleaning vehicle etc., and when running into rainstorm weather, part rainwater can be by overfall in overflow pipe flows into municipal drainage pipe network.
Described biotinylated biomolecule delaying basin 3 should be arranged on physical features relatively lower, it is ensured that oozes, accumulate and purifies under rainwater.
The quantity of planting plants can be determined according to the specification of actual construction biology delaying basin.Floristics can be according to local climate condition and combine ecosystem characterization etc. and determine.
Rainwater treatment flow process:
The rainwater of rainwater → opening vertical curb and the accumulation of gravel mulch layer buffering → lignosa purification → charcoal packing layer and purify again → gravel drainage blanket → flow into through overflow pipe municipal drainage pipe network or cistern → clean.
The above only have expressed embodiment of the present utility model, and specifically describes, but is not the restriction of the present invention, all some amendments made within this intention spirit and principle and improvement, all should belong to the protection domain of this intention.
