Abstract

The present invention relates a collection and treatment system of domestic sewage and rainwater in residential community, which is used for roof plantation. The invention includes constructed wetland, underground sewage and rainwater collection and treatment structure, roof irrigation device and planting soil layer. The principle of the underground sewage and rainwater collection and treatment structure separated into reservoir, wetland clear water tank and sewage well, is: first, the sewage after treatment flows through pipes into the reservoir which has a sewage pump arranged on its base; second, the sewage is lifted by the sewage pump to constructed wetland which filters the sewage; then, the filtered sewaged flows into wetland clear water tank which also has a pump arranged on its base and has pips connected with the roof. The roof irrigation device includes a plurality of clear water boxes arranged on the roof, outlet pipes, and drip irrigation pipes. The planting soil layer is layed averagely on the roof in a manner that a soil layer with a soil layer depth of 10cm and a soil bulk density of 120kg/m<2>, is layed on a geotextile layer layed on a water storage board which is layed on a thermal insulation board.

Description

A kind of residential area sanitary sewage and rainwater collection and treatment are used for the roof planting system
Technical field
The invention belongs to field of environment protection, particularly a kind of residential area sanitary sewage and rainwater collection and treatment are used for the roof planting system.
Background technology
Uptown sanitary sewage all is to flow into sewage treatment plant or enter the river through drainage system, drains into the polluted river water of wanting in river, also will pollute the environment and the face of land of effluent stream warp.Simultaneously also to environmental air pollution, and easily produce harmful fly.For the processing of uptown sanitary sewage reuse is again arranged also after the integrated treatment taked in recent years, as Chinese patent 200410023763.X number, also have sanitary sewage and rainwater collected and just carry out after the biochemical treatment again as flushing the toilet or watering water, as Chinese patent application 97109845.X, also have other processing method, do not enumerate one by one.These domestic sewage processing methods respectively have advantage, are inclined to differently, all are to adopt bio-carrier to dispose of sewage so that reuse basically.Basically all exist technology more complicated, treatment conditions are higher, the problem that the reuse effect is lower.
Summary of the invention
The objective of the invention is to solve existing sanitary sewage and the existing defective of rainwater treatment system, provide a kind of residential area sanitary sewage and rainwater collection and treatment to be used for the roof planting system.
For solving the problems of the technologies described above, the present invention is by following technical solution: a kind of residential area sanitary sewage and rainwater collection and treatment are used for the system of roof planting, comprise artificial swamp, underground sewage and rainwater collection and treatment structure, roof irrigation rig and planting soil layer, wherein, described artificial swamp is made of soil sand stone layer and face of land greening thing, and is positioned at subsurface 0.15 to 2m place; Described underground sewage and rainwater collection and treatment structure are divided into bilge well, cistern and wetland clear water reserviors, the sewage well depth is 2m, and cistern is located at underground 0~3.2m place, and the wetland clear water reserviors are located at underground 2~3.2m place, the wetland clear water reserviors are equipped with water pump at the bottom of the pond, are connected to the building top layer by pipeline; Described roof irrigation rig comprises the suitable filtered water tank of N location interval placing the roof, is located at the water inlet pipe on filtered water tank top, is located at the outlet pipe of filtered water tank bottom and the drip irrigation water pipe that is connected with outlet pipe; Described planting soil layer on average is layed on the roof, include one deck water storage board of being arranged on the original thermal insulation board in roof, be arranged at one deck geotextiles on the water storage board and evenly be layed in soil horizon on the geotextiles, the thickness of the thermal insulation board on roof is 4~6cm, the thickness of water storage board is 1.5~3cm, soil horizon thickness is 10cm, and the bulk density of soil is 120kg/m 2Sanitary sewage enters cistern after handling through the preliminary sedimentation of bilge well, through being promoted to artificial swamp by the sewage pump at the bottom of being located at the cistern pond through pipeline after the filtration treatment of cistern, flows into the wetland clear water reserviors after the filtration treatment of artificial swamp again; Rainwater flows into artificial swamp and flow into the wetland clear water reserviors after the filtration treatment of artificial swamp; By being arranged at the water pump at the bottom of the wetland clear water reserviors pond water in the wetland clear water reserviors is promoted and flow into filtered water tank through water inlet pipe; Current in the filtered water tank are irrigated the planting soil layer through outlet pipe, drip irrigation water pipe.
Water storage board is the planar shaped by plastic production, be to embark on journey by protruding circular arc apportion, every row space is identical with the recessed round pool degree of depth is set, this round pool bottom is the plane, diameter be slightly less than near coal-mine above, dark 1.0-2.5cm is provided with circular protrusions between every capable round pool, and its height is identical with the ranks circular arc bar of projection.
Described planting soil layer is planted shallow great soil group plant.
The interval of drip irrigation water pipe is provided with and matches with planting density.
Useful technique effect of the present invention is: 1, the residential quarters greening is had with sewage disposal system and mix, make sanitary sewage disposal not go out the sub-district, save the water source; 2, sanitary sewage and rainwater are handled in cell range, and be used for the greening of this sub-district, do not need to build again special bilge well owing to make full use of existing bilge well; 3, artificial swamp of the present invention can make full use of existing green land in the sub-district, but not enough green land processing and sorting is the qualified wetland of using to the part bed thickness, handles needs to satisfy sewage water filtration.The water outlet that artificial swamp was handled reaches " agricultural irrigation water standard " (GB5084-92), and the artificial swamp treatment scale is 10m 3/ h, floor space 50m 24,, can satisfy the needs of greening and pouring roof plant because cistern is darker, and reservoir storage is more; 5, the roof planting soil horizon belongs to the shallow layer of planting, and is fit to high added value crops such as plantation strawberry, and institute's plant of planting is in to sell, and gained is taken in the expense that can replenish construction system of the present invention; 6, roof planting is edaphic rational in infrastructure among the present invention, and its water storage board is reasonable in design, but dischargeable capacity pouring infiltration make in the soil moisture content obtain the long period and replenish, water-saving result is remarkable; 7, the roof irrigation system is provided with rationally, and reasonable to the output distribution of drip irrigation, water yield is regulated simple and effective; 8, artificial swamp is handled sanitary sewage and combined, make the roof four seasons evergreen, also, need not apply fertilizer to plant separately owing to be rich in plant desired nutritional thing in the sanitary sewage with roof greening; 9, the roof planting soil horizon is more shallow, meets the roof load standard; 10, the system that builds according to technical solution of the present invention makes sewage become recycle-water, and rainwater no longer runs off, and is used for subdistrict greening, has economy, easy row, effective remarkable advantage.
Be described further with reference to the accompanying drawings below.
