Abstract

The invention solves a method of liquidating soil residues from railway superstructures in locations of little water management significance. It is carried out by ploughing the residues into the soil in an amount of 100 to 300 t.ha-"^ to a depth of 10 - 15 cm, simultaneously adding microflora donors, aerating the topsoil and finally restoring the soil water regime.

Description

Invention of epoeobic liquids of railway superstructure

During the repair of railway tracks, the sieves are sifted behind the railway superstructure, the act generates waste in the form of slips, i. soil seeped by petroleum hydrocarbon. At present, these preaevky are either stored on heaps along the track or incinerated with the addition of an enegretic eyebrow. There is a danger of leakage of petroleum hydrocarbons into similar wastewater and their disposal by storage of dumps on heaps. By burning aa or eooe, this heavily blew away, but it is economically disadvantageous, since they are consuming noble energy sources.

Methods for disposing of sludge and sediments derived from petroleum and its derivatives are known, which are based on the production of a product for the feeding of microorganisms whose activity and degradation of petroleum hydrocarbons. The product aa is formed from mineral acids, alkali metal or alkaline earth salts and an organi-hydrophilic substance, in particular molasses, but from substances from the group consisting of molasses, cellulose, beet refuse, malt extract, from the substance group reduces surface tension to allow mixing with a hydrocarbon consisting of silicates of calcium, eodl and dalsal, calcium, sodium and potassium carbonates, medium hydrogen and calcium phosphates, and acidic or attentive ammonium phosphates and further from a liquid or solid diluent to treat the composition. The product can be formed from the same product as the preceding product with the addition of an organic acid of the lactic, ootic, eitronic, glutaconic, itaconic and tartaric acid groups without diluent · The method of disposal of petroleum hydrocarbons using the above products individual components.

However, the aforementioned epobodies are very expensive and e.g. not suitable for railroad track footings likvldáoiu ·

The abovementioned deficiencies are remedied by the eradication of soil remedies from railway superstructure, which is based on the fact that the soil is plowed into the soil in quantities of 100 to 300 t; ha '^ to a depth of 10-15 with simultaneous addition of donors of microflora, which are livestock manure, vitah, excrement of livestock, activation sludges such as e.g. Zigzag falls from the surface of the banks of the Little Danube and other activation soil and high echopnoet excreted COg, in the amount of 0.5 to 1.5 t.ha ¹ * · Ornioa aa for 6 moslaoov in monthly intervooh aerates and finally adjust the water regime of the pod to a span of 30 to 60% of the utilized water capacity with the aim of achieving an intense breakdown of petroleum hydrocarbons by means of an aerobic underwater microflora. During the decomposition of petroleum hydrocarbons, p8da is used to peat in industrial crops, hemp, hemp and technical crops. After a three-year poisoning of the technocarbon crops, a gas-hydromatographic check of the petroleum hydrocarbon content is carried out, after which other crops may be grown in the normal manner of the cropping process. This likvldáola is carried out in low water management sites in defloit and sandy falls.

The advantage of the proposed solution is that soil sowing, which has so far been laid loose on the soil and polluting the environment, mainly through slips, or with limited costs and at considerable cost, is economically liquidated and used as a source to increase bioenergy potential, particularly matter and illusion. In addition to the economic liquidation of the invention, the invention contributes to the improvement of the environment, in particular hydro

A further advantage is that it destroys petroleum hydrocarbons in a natural way without the need for additional chemicals and construction or machine investment. Last but not least, it increases the amount of biomass grown in industrial crops.

Example:

In the elimination of the sieves ea selected a suitable agricultural site in the water management area of low importance on the deficient soil of the experimental pole of the Kostolíštš research base. Uneven rail superstructure was superimposed on the surface of the soil in a quantity of 200 t.ha ^-1 . They added microflora donors in the form of manure or manure in an amount of 1 t.ha ^-1 . The fertilizer slurry was plowed to a depth of 15 cm with a conventional cultivation tool. Cultivation aeration was performed at monthly intervals for 6 months.

After the above operations, hemp was sown in the first year, ropes for the next year and technical sorghum for the next year, while the water regime was adjusted to 60% of the available capacity.

After three-year cultivation of industrial crops and subsequent gas-chromatographic control, the content of petroleum hydrocarbons was a negative result and it was possible to grow other crops in the normal crop rotation.

213 628 Another advantage is that it disposes of petroleum hydrocarbons naturally without the need for additional chemicals and construction or engineering investments. Last but not least, increasing the amount of biomass of cultivated crops, Example: When disposing of slags, a suitable agricultural site was selected in the low water management area of the experimental pole of the experimental poles of the Kostolíště research base. t.ha-1. Microflora donators in the form of manure manure were added at 1 t.ha. Solid manure screenings were plowed into the depth of 15 cm with conventional culture tools, aeration was carried out at a monthly intervals for 6 months with a cultivator. After the above actions, the first year was planted with hemp, for the next year the ropes and the next technical sorghum, while the water regime was adjusted to 60% of usable capacity. After growing crops for three years and the subsequent gas-chromatographic control, the content of petroleum hydrocarbons was negative and further crops could be grown in normal crop rotation. OBJECT. THE INVENTION 1. A method of disposing of overheads from railway uppers in water-insignificant locations, characterized in that sifting into the substructure at a rate of 100 to 300t.ha " 1 to a depth of 10-15 cm with the addition of microflora donators in the amount of 0.5 to 1.5 t.ha, orniea is aerated for 6 months and finally water-treated to dissolve 30-60% of the usable water capa. 2, A method of disposing of sieves according to claim 1, characterized in that the microflora donators are manure, winemakers, farm animal excrements, and activates.
