Problems solved by technology

This method is either to install a feces collection box to reduce or avoid discharge along the way, but it increases the burden on train operation, and at the same time increases the follow-up cleaning work; or adds an online biodegradation device, but the structure is complex, expensive, and difficult to maintain
[0004] There is no public report on the greening of railway track beds at home and abroad, and it is currently a blank field. The biodegradation of train excreta is blank in theory and practice.

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] The overall idea: use green plants to degrade the pollutants excreted along the train; considering that the railway track bed is made of stones, it is difficult to directly green, so the container cultivation method (that is, the cultivation of plants in containers with nutrient substrates) is introduced, and the planted The container with plants is placed on the railway track bed; the excrement is isolated and collected by the container placed between the sleepers, absorbed and degraded by the green plants, and the plants just use these nutrients and waste water, which can avoid water and fertilizer management. When it is necessary to perform ballast cleaning or railway maintenance operations, the greening container can be moved down the track.

[0019] In order to achieve the above expected effects without affecting the normal operation of the ...

Abstract

The present invention proposes biological treating method of railway pollution, and green plant is utilized in degrading pollutant from train to the railway. Plant is cultivated in container with nutritive medium and the container is set on railway to collect the pollutant. In the container, the pollutant is absorbed and degraded during plant growth. During maintaining the railway bed, the green container is taken out the railway.

Description

technical field [0001] The invention relates to a treatment method for environmental pollution, more specifically, the invention relates to a biodegradation, treatment and afforestation method for the environmental pollution of an iron track bed. Background technique [0002] my country's trains generally use open straight-line toilets, and feces and domestic sewage are directly discharged to the railway, which is jokingly called the train defecating everywhere. At present, the total length of my country's railways has exceeded 71,500 kilometers, and the annual number of passengers transported has reached 1.05 billion. Calculated based on the discharge of 0.5 kg of feces and 1.5 kg of urine per person per day, it is conservatively estimated that the amount of feces and urine sprinkled on the railways in the country is 3,000 tons every day. More than 1 million tons. It causes serious soil and groundwater pollution, deteriorates the working environment of railway workers, and ...
