The beneficial effects of the utility model reside in that: the system adopts dry-wet double-line treatment, solid-liquid separation of excrement, two sites exchange compost fermentation, two ponds alternately store liquid and oxidize, the whole production process is impermeable and leak-proof, the full treatment of the excrement generated by the pig farm is ensured, the ecological environment safety, the breeding production safety and the public health safety are ensured, and meanwhile, the produced solid and liquid organic fertilizers can also be applied to agricultural production to change waste into valuables.

Description

Harmless treatment system for excrement in large-scale pig farm

Technical Field

The utility model belongs to the dirty innocent treatment field of excrement, in particular to dirty innocent treatment system of scale pig farm excrement.

Background

In recent years, with the rapid development of livestock husbandry in China, the livestock breeding amount shows a rapid growth trend. The method greatly promotes the transformation and upgrading of the modern animal husbandry in China and the improvement of quality and efficiency, and is beneficial to establishing new advantages of animal husbandry economic development.

Due to the fact that the breeding amount is excessively and rapidly increased, the problem of environmental pollution caused by livestock and poultry breeding is increasingly serious, production safety of livestock industry is affected, and ecological environment safety is endangered, so that the method becomes a social problem which is generally concerned by people.

The method is an effective measure for taking two measures at a time by vigorously implementing planting and breeding combination and applying the manure generated by the breeding industry to farmlands. However, direct application of the manure from the farm to the farm produces a "seedling burning" phenomenon, which is too costly for the innocent treatment of the manure and is not recognized by the farm owners and the organic fertilizer production enterprises, and therefore, the establishment of an economical, practical and novel manure innocent treatment system near the large-scale pig farm has become a problem to be solved urgently.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model provides a dirty innocent treatment system of scale pig farm excrement takes dry and wet double-line processing in this system, the dirty solid-liquid separation of excrement, two place exchange compost fermentations, two pond stock solutions oxidation in turn, whole prevention of seepage leak protection of production has ensured the dirty total volume of excrement that the pig farm produced and has handled, has ensured ecological environment safety, aquaculture production safety and public health safety, and simultaneously, the solid and the liquid fertilizer of producing can also be used to agricultural production "changing waste into valuables".

Therefore, the utility model provides a dirty innocent treatment system of scale pig farm excrement, including piling manure field A, piling manure field B, fecaluria effluent water sump, solid-liquid separation equipment, primary treatment pond, secondary treatment pond, tertiary treatment pond, oxidation pond A, oxidation pond B.

As a further improvement of the utility model, a manure piling field A and a manure piling field B are arranged on the solid organic fertilizer production line in the manure harmless treatment system. By adopting the technical scheme, one field can be fully fermented after being filled with the manure to produce solid organic fertilizer, and the other field can be continuously transported to store the manure.

As a further improvement, the liquid organic fertilizer production line in the feces harmless treatment system is provided with a feces and urine sewage pool. By adopting the technical scheme, the temporary storage of the excrement and urine sewage led out from the pig farm through the siphon pipeline is facilitated.

As a further improvement, the fecaluria effluent water sump right side is equipped with solid-liquid separation equipment, the solid-liquid separation equipment right side is equipped with primary treatment pond, secondary treatment pond, tertiary treatment pond in proper order, the tertiary treatment pond right side is equipped with oxidation pond A, oxidation pond B side by side. By adopting the technical scheme, the solid-liquid separation of the excrement in the excrement and urine sewage pool is facilitated, the solid-liquid separation is further facilitated through three-stage treatment, and the separated liquid is further oxidized to produce the liquid organic fertilizer.

Drawings

FIG. 1 is a schematic flow chart of a large-scale piggery fecal sewage innocent treatment system of the utility model.

The harmless treatment system for the excrement in the large-scale pig farm is further explained by combining the attached drawings.

As shown in figure 1, the utility model relates to a harmless treatment system of scale pig farm excrement, including solid heap excrement yard A1, solid heap excrement yard B2, fecaluria effluent water sump 3, solid-liquid separation equipment 4, primary treatment pond 5, secondary treatment pond 6, tertiary treatment pond 7, oxidation pond A8, oxidation pond B9. On the solid organic fertilizer production line, the solid manure yard A1 is adjacent to the solid manure yard B2. On a liquid organic fertilizer production line, a solid-liquid separation device 4 is arranged near the excrement and urine sewage tank 3, a primary treatment tank 5, a secondary treatment tank 6 and a tertiary treatment tank 7 are sequentially arranged on the right side of the solid-liquid separation device 4, and an oxidation pond A8 and an oxidation pond B9 are arranged on the right side of the tertiary treatment tank 7.

Detailed Description

The utility model relates to a dirty innocent treatment system of scale pig farm excrement, the embodiment is specifically introduced below.

The solid manure collected by dry cleaning manure in a large-scale pig farm is transported to a manure piling yard A1 by using a closed transport vehicle, when the manure piling yard A1 is full, composting fermentation is carried out to produce solid organic fertilizer, and then the solid manure newly collected by dry cleaning manure is transported to a manure piling yard B2 for exchanging and using two manure piling yards.

In a manure sewage pool under a large-scale pig farm slotted floor, manure sewage is collected into a manure sewage pool 3 through a siphon pipeline, and then the manure sewage in the pool is guided into a solid-liquid separation device 4 through a sewage pump for solid-liquid separation.

Solid manure residues generated by solid-liquid separation are directly conveyed to a manure piling field A1 or a manure piling field B2 for composting fermentation to produce organic fertilizer, dirty liquid generated by solid-liquid separation sequentially passes through a primary treatment tank 5, a secondary treatment tank 6 and a tertiary treatment tank 7, and residual solid manure residues filtered in each secondary treatment tank are conveyed to a manure piling field A1 or a manure piling field B2 for composting fermentation to produce organic fertilizer.

After the polluted liquid is subjected to three-stage treatment, the liquid from the three-stage treatment tank 7 flows into the oxidation pond A8 or the oxidation pond B9 for storage and oxidation, so that the liquid becomes a liquid organic fertilizer.

By adopting the technical scheme, dry-wet double-line treatment, solid-liquid separation of excrement and sewage, compost fermentation exchange of two sites, alternate stock solution oxidation of two ponds, seepage prevention and leakage prevention in the whole production process are realized, the full treatment of the excrement and sewage generated by a pig farm is ensured, the safety of ecological environment, the production safety of breeding industry and public health safety are ensured, and meanwhile, the produced solid and liquid organic fertilizers can also be applied to agricultural production to change waste into valuable.

The above embodiments are preferred embodiments of the present invention, the scope of the present invention is not limited to this specific embodiment, all equivalent changes made by the shape and structure of the present invention are within the protection scope of the present invention.
