Method for integrated compost treatment of dead pigs and pig manure

Abstract

The invention discloses a method for integrated compost treatment of dead pigs and pig manure. The method comprises the following steps that after the pig manure and auxiliary materials are evenly blended according to a certain proportion, the mixed materials are shoveled by a shovel car to the ground of a compost workshop and laid 60 cm thick; the dead pigs are stacked on the materials, wherein bodies of the dead pigs are over 20 cm far away from the walls on the periphery of the workshop, if each single dead pig is over 100 kg heavy, the dead pigs need to be placed at the interval of 20 cm, and dead fetuses, afterbirth, suckling piglets and the like can be placed in groups; the bodies of the dead pigs are at least covered with 30-centimeter-thick evenly-blended materials; a stacking body is ventilated according to the ventilation quantity of 60 L / min to 100 L / min per cube; compost is fermented for 42 days, the compost is turned over in the fourteenth day and the twenty-eighth day, water can be supplemented appropriately in the compost overturning process, and muscles which are not dissolved are covered with the materials after the compost is turned over. The method for integrated compost treatment of the dead pigs and the pig manure has the advantages that harmless treatment of the dead pigs is achieved, the problem of treatment of the pig manure is solved, a special device is not necessary, a microbial agent does not need to be additionally used, operation is simple, cost is low, and secondary pollution is avoided.

Description

technical field [0001] The invention belongs to the field of agricultural waste treatment and resource utilization, and relates to an integrated composting treatment method for pig manure and dead pigs. Background technique [0002] In the process of large-scale livestock and poultry breeding, animal death due to normal production and diseases is inevitable. Therefore, the disposal of dead livestock and poultry is a problem that every farm must face. If animal carcasses cannot be properly disposed of, not only will the Potential biosafety problems are caused, and dead livestock and poultry are likely to flow into the market, seriously threatening people's health. [0003] According to the "Pilot Program for Establishing a Long-term Mechanism for the Harmless Treatment of Diseased and Dead Pigs" issued by the Ministry of Agriculture in 2013, the current harmless treatment of sick and dead pigs mainly includes four methods: deep burial, incineration, high temperature and high ...

AI Technical Summary
