Abstract

SUMMARY OF THE INVENTION: the method includes fencing a section of the floor with a slope of the embankment dams to form checks, arranging the outlet channels behind the dams, forming rolls and furrows perpendicular to the slope on the surface of the checks, spreading liquid organic waste from the upper part of the checks on the surface, dewatering the washed organic waste and the discharge of clarified water through the discharge ditches. To increase the efficiency of the method, the lower part of the rollers is made of straw, and the upper part is made from soils, peat or sand that are light in mechanical composition, furrows are formed from the lower sides of the rollers, and after dehydration of organic waste, they are raked together with the rollers into compartments and composted . Before washing liquid organic waste, a layer of straw can be laid on top of the rollers and furrows, and when washed, the supply of organic waste can be carried out under this layer. Before forming rolls and furrows on the surface of the checks in the subsurface layer of the checks, molehills can be made with their output along the slope of the check into the discharge ditches. The base of the embankment dams can be made of straw. 3 s.p. f-ly, 3 ml.

Description

The invention relates to methods for preparing fertilizers and can be used in agriculture.

The purpose of the invention is to simplify the preparation of organic fertilizers.

An example embodiment of the method is shown schematically in FIG. 1, 2, 3 (section along the slope of the check).

The method is carried out on a planned slope with arable layer of soil 1 and arable layer 2, along the slope or under

moles 3 are made at an angle to the horizontal in the subsurface layer. Straw, peat, sand are laid sequentially across the slope with strips 4 (Fig. 1). Then, grooves 5 are cut across the slope of the slope (Fig. 2). Furrows 5 are cut from the lower slope side of strips 4 so that rollers 6 are formed above strips 4 from the arable layer of soil taken out of furrows 5, and when rollers 6 are formed, the arable layer of soil should not fill the upper slope of strip 4 (which achieves under00

che a yu

boron strip width A and the depth of plowing when the device furrows 5).

A layer of straw (or other material with high water permeability) 7 is laid along the lateral and lower borders of the check, and then outlet channels 8 are arranged, the soil being removed during their construction and used to form spoiling dams; 9. At the same time, the soil forming the embankment dam 9 must also be removed from the discharge ditch 8, and also should not fill the edge of the straw ribbon 7 inside the check.

A feed pipe 10 with water outlets is laid in the upper slope of the check. Through pipeline 10, activated sludge and (or) unclarified livestock waste water are fed to the upper slope of the check. They spread over the surface of the check, filtered through the belt 4 and partially through the soil of the rollers 6. However, the upper edge of the belt 4, which is not covered by the soil of the rollers 6, facilitates the filtering process. As the belt 4 and the rollers 6 become clogged, the wastewater fed to the check will overflow through the caked roller and the process will continue on the next slope roller. It should be noted that the caked roller and furrow form a micro-estuary in which a precipitate will form.

After complete colmatation of all furrows and rollers, watering is stopped.

Through molehills 1 and a layer of water-permeable material 7 of the base of the dams, the excess moisture (clarified fraction of effluents) flows into the outlet channels 8 and then to a storage (not shown), from which they are used for irrigation or for additional cleaning.

After reducing the moisture content of the solid fraction of effluents on the check and the material of the accumulated rollers to optimal limits, the rollers, together with the precipitated solid fraction of effluents and activated sludge, are raked into shafts that can withstand a period sufficient for biothermal disinfection and composting. After that, the resulting compost is applied to the field.

G;.

If necessary, arable soil layer is added and the process is repeated.

The method can be implemented in the winter. To do this, a straw layer 11 is laid on top of the rollers and furrows, and sewage and activated sludge are fed under this layer (FIG. 3). In this case, the straw layer floats onto the surface of the liquid supplied to the pin and prevents rollers 6 and tape 4 from freezing The method is recommended to be performed in areas with a poorly permeable subsurface layer with a deep groundwater level, otherwise it is necessary to install anti-filter screens.

Tapes from straw, peat, sand can

apply, for example, using modified manure spreaders (with a reduced working width). Furrows 5, rollers 6, as well as ditches 8 and dams 9 are made, for example, using plows providing the required plowing depth.

The composition of the material for the device of tapes 4 select the outcome from the composition of the effluent and activated sludge supplied to the check, as well as from the composition of the soil for the arrangement of rollers

0 in order to ensure the optimal composition of the compost.

Molehills 2 are made at an angle to the horizontal, ensuring their optimal slope.
