Greening for the rail railway roadbed was not openly reported both at home and abroad, was blank field at present, all was in blank for the excremental biodegradation of train in theory and practice.The container culturing technology that wherein relates to is ripe, and in the history in existing 30 years of developed country, in recent years, container culturing began to show up prominently and present good growth momentum in China.These are laid a good foundation for the present invention.
Summary of the invention
At problems of the prior art, the present invention proposes biodegradation, improvement, the greening method of a kind of rail railway roadbed environment pollution.
Technical scheme of the present invention is: a kind of biological treating method of railway pollution is characterized in that: the container that will plant plant places on the railway ballast.
Above-mentioned biological treating method of railway pollution, it is further characterized in that described container is the container that nutrient matrix is housed; Described nutrient matrix is the soil with strong water erosion resistent ability.
Above-mentioned biological treating method of railway pollution, it is further characterized in that described plant is short life, evergreen, happiness sun plant, for example can be in Festuca Arundinacea, rye grass, Korea lawn grass, Bermuda, winter creeper, trachelospermum jasminoide, the Boston ivy etc. one or more.
Above-mentioned biological treating method of railway pollution, it is characterised in that further described container is a jerrycan, bead and sleeper are contour or slightly high, the size outline is less than the grid of track and sleeper composition, but to cover the exposed space in the track as much as possible, certain antidetonation and weather resistance effect to be arranged simultaneously, so need add the ceramic vessel of plastics or foam overcoat.Also can directly select plastic containers for use for saving cost, but should be the speciality that meets above-mentioned requirements.
The employing of railway pollution biological treating scheme of the present invention can obtain following beneficial effect:
(1) ecological benefits.
A. the greenery patches increment is considerable.The intensive utilization soil improves afforestation coverage rate.China's rail width is 1.435 meters, if china railway all builds up green track, and by 70,000 kilometers of present china railway length overalls, about 100,000,000 square metres of newly-increased green area; According to 100,000 kilometers meters of the year two thousand twenty china railway planning length overall, about 1.4 hundred million square metres of newly-increased green area.If rail outside roadbed is counted, then green area is close to and doubles.
B. ecoaesthetics effect.Build up green railway by greening, constitute the vertical planting system jointly, improve railway view along the line, form the vision aesthetic effect of " people is on green, and the people is in scape " with railway both sides avenue tree.Compare and the both sides greening of traditional railway, can improve landscape richness, and alleviate train operator's visual fatigue, reduce accident rate based on woody (avenue tree) plant.
C. environmental benefit.Train excreta on interception and the degraded rail, prevent subgrade soil and groundwater pollution, form the indirect regeneration of " train excreta---container---herbaceous plant ", change ight soil is fertilizer, rely on the sterilizing function of plant simultaneously, eliminate the parasitic germ in the ight soil, the propagation of source control communicable disease, this seems particularly urgent after SARS and bird flu incident.
(2) social benefit.Afforest with suiting measures to local conditions, can save a large amount of land resources, help sustainable using of land resources; Cultivating container has the covering effect to track, forms separation layer between refuse and track, prolongs the ballast aggregate cleaning cycle, uses manpower and material resources sparingly; The excretas such as train ight soil, waste water of degrading simultaneously improve railway worker's working environment, reduce the risk of transmission.
Description of drawings
Fig. 1 is the design sketch of biological treating method of railway pollution of the present invention.
