Abstract
The invention discloses an innocent static aerobic composting treatment method for silkworm excrement. The method comprises the following steps of: 1) putting up an open floor on the bottom of a treatment tank; 2) spreading a layer of conditioner on the open floor; 3) pouring mixture of the silkworm excrement and the conditioner on the layer of the conditioner and spreading, or alternately poring the silkworm excrement and the conditioner to obtain a plurality of composite layer piles and then spreading; and 4) finally covering a layer of conditioner on the surfaces of the piles in the treatment tank. A layer of mushroom residues is coated on the bottom of a silkworm excrement tank and the surface of the silkworm excrement respectively, so that the direct contact between the silkworm excrement and natural environment can be avoided, the function of heat preservation can be exerted, and different parts of silkworm excrement have the high enough temperature; and therefore, the whole high-temperature aerobic fermentation effect of the silkworm excrement tank can be guaranteed, the fermentation and composting speed of the silkworm excrement is accelerated, and the effect of killing pathogens in the silkworm excrement can be improved.
Description
Technical field
The present invention relates to a kind of silkworm excrement refuse processing method, especially relate to the innoxious static aerobic composting treatment method of a kind of silkworm excrement.
Background technology
Silkworm excrement is the important waste in breed silkworms producing, and except refering in particular to the solid manure that silkworm larva discharges, also comprises residual mulberry, the bedding and padding in the silkworm rearing bed and silkworm body and seat sterilizing agent etc. and some die of illness silkworm and small and weak silkworm corpse that food is surplus on producing.Because the inevitable various infectivity flacherie cause of diseases that exist are processed without safe in the silkworm excrement, very likely production are caused a significant threat.Especially can breed silkworms in 1 year in south China silkworm district in 8-9 month, silkworm is criticized and joins end to end, and the quantity of silkworm excrement constantly increases, and it is serious arbitrarily to abandon phenomenon, has become new rural area public hazards in part silkworm district.Because silkworm and mulberry production has significant dispersed petty-farmer management feature, measure large, wide, dispersion, huge numbers of families' silkworm excrement is difficult to carry out batch production and processes and fully utilize.Therefore, research and development practical innoxious process for treating simple, strong operability has important realistic meaning.
According to being processed on-site investigation, south China silkworm district silkworm excrement finds, except most silkworm excrements are arbitrarily abandoned, also there is part silkworm family silkworm excrement can be carried out doing Fertilizer application after stack retting is processed, but most processing modes are simple, it is the not turning of simple stack retting, therefore silkworm excrement surface and bottom can't form the aerobic composting fermentation condition and cause ferments insufficiently, and can not produce enough high temperature and kills cause of disease, and sterilization is not thorough.
At present, research there is not yet the research report about silkworm excrement cause of disease compost hazard-free, present method is namely for rural production present situation nowadays, and it is innoxious and reduce a kind of summary silkworm excrement static compost method of environmental pollution to carry out the pollution, the flacherie that are intended to solve on the spot silkworm district silkworm excrement waste.
Summary of the invention
The object of the present invention is to provide the innoxious static aerobic compost method of a kind of silkworm excrement, the method less investment operates simple and easyly, and effect is remarkable.
For realizing the object of the invention, the present invention realizes by following technical measures: the innoxious static aerobic composting treatment method of a kind of silkworm excrement, may further comprise the steps,
(1) the bottom built with treating pond forms Stilt layer;
(2) at frame tiling one deck amendment;
(3) after the amendment layer is poured the mixture of silkworm excrement and amendment into, pave, or pour silkworm excrement in turn, amendment forms and paves after a plurality of composite beds are piled up;
(4) cover again at last one deck amendment on the top layer for the treatment of pond stores.
Built on stilts floor height 8-11cm of the present invention; The amendment thickness that tiles at frame is 5-10cm.
The weight ratio of silkworm excrement and amendment is 7～9:1～3 in the silkworm excrement amendment mixture of the present invention, and piling height is 80-90cm, and adopting the carbon-nitrogen ratio (C/N) of silkworm excrement is 10～30:1.
Silkworm excrement amendment composite bed of the present invention is pressed the compound accumulation of silkworm excrement-amendment-silkworm excrement successively, and the weight ratio of layering silkworm excrement and amendment is 8:2; Piling height is 80-90cm, and adopting the carbon-nitrogen ratio (C/N) of silkworm excrement is 10～30:1.
It is 5-10cm that top layer of the present invention covers one deck amendment thickness at last.
Amendment of the present invention is selected the materials such as bacterium chaff or husk.
The present invention has following beneficial effect:
(1) owing to adds one deck bacterium chaff in bottom, silkworm excrement pond and silkworm excrement surface, can avoid silkworm excrement directly to contact with physical environment, play the effect of insulation, guarantee that the silkworm excrement different sites all produces enough high temperature, thereby ensure the high-temperature aerobic fermentation effect of silkworm excrement pond integral body, both accelerate the speed of silkworm excrement fermentation maturity, also improved the killing effect to cause of disease in the silkworm excrement.
(2) in accumulation, add a certain proportion of amendment, can play the C/N ratio that improves windrow on the one hand, added on the other hand dry amendment and can make the suitable water cut of silkworm excrement, reached suitable water ratio scope.The part unpleasant odor that simultaneously adsorbable silkworm excrement fermentation produces has improved the pollution of compost fermentation to air.
(3) the treating pond bottom is built on stilts, makes silkworm excrement bottom well-ventilated, oxygen supply abundance, improves the effect of fermentation.
