Abstract

The invention relates to agriculture, in particular to manure management technology. The aim of the invention is to ensure the full utilization of manure and reduce the complexity of the method. Manure, after removal from the livestock storage, is stored on the storage area by layer-by-layer frosting. Snow edges are arranged around the edges of the storage area. With the onset of the warm season, as the stored manure is defrosted, the liquid fraction flows down from the site and is collected in a liquid collector. The solid fraction left behind is mixed with the peat, removed from the storage area and borted into the stack. As the manure is defrocked, the process of adding peat and boring is repeated, and in each subsequent cycle a fresh mixture of the solid fraction of manure and peat is mixed with the previously boring mixture during storage in the shoulders. After forming the entire mass of the stored manure into the piles, the mixture is composted. 3 il. with (L

Description

The invention relates to agriculture, in particular to manure disposal technology.

The aim of the invention is to provide. baking full utilization of manure and reducing the complexity of the method.

FIG. 1 shows schematically a reservoir, a plan; in fig. 2 shows section A-A in FIG. 1j in FIG. 3 is a schematic diagram of composting and boring.

Manure from livestock rooms to storage is delivered by mobile transport and dumped at site 1 .- warehousing. In the initial period of livestock housing, when the ambient temperature is still high, manure is stored from the middle of the site. With a decrease in temperature and accumulation of snow cover, snow shoulders 2 (Fig. 2) with a height of 0.25-0.30 of the thickness of the manure layer being frozen can be arranged. By the time of layer-by-layer freezing of manure to the level of snow claps, the outside air temperature drops to -30 and -40 ° C, later it reaches -55 ° C. After the barriers are formed, the manure is stored over the entire storage area to the established thickness.

With the onset of warm days and as the defrosting of the stored manure (Fig. 2 and 3) with the simultaneous flow of the process of sedimentation from the area of the JV

The ki flows down the liquid fraction and along the grooves 3 enters the fluid collector 4, from which the liquid fraction is taken and applied to the pop fluid as spreaders. Then, in the thawed layer of the remaining solid fraction of manure, passages 5 are laid in direction 6, parallel to the bouting platform 7, which are immediately filled with peat or other prepared organic materials. After that, all the melted manure, together with peat, is bulldozed from the storage area and borted to stack 8, and in the np cessing process the components are mixed, In the bursts, the mixture is self-heated, composted, and manure is disinfected.

As the manure is further defrosted at the storage site, the process of peat application and boring is repeated, the fresh mixture of manure and peat is mixed during the formation of the collar with the previously boiled mixture. This process is repeated until the end of the manure at the storage site, which is then prepared for the new manure storage season. The storage thickness of the cargo (Fig. 3) during the storage period in case of layer-by-layer freezing is selected based on the composting and fertilization possibilities in the current year, i.e. the last cycle of the peat mixture should be

carried out no later than mid-summer.

The use of the proposed method allows, with little material and labor costs, to organize the effective storage and use of manure for the preparation of fertilizers, contributes to the improvement of the sanitary condition of farms, the protection of approx. The environment allows for the processing of manure of any kind, and litter, and bespodtilnochny, and drains of livestock farms.
