Description

A kind of sick dead pig harmless environmental protection treatment process
Technical field
The present invention relates to a kind of sick dead pig harmless environmental protection treatment process.
Background technology
In recent years, along with the ever-increasing demand of the people, the pig farm of China also constantly increases, even if there is high-caliber management, pig farm is also kept away and unavoidably run into sick dead pig.Sick dead pig can be propagated and spread epidemic disease, and this not only can cause financial loss, also pollutes the environment, and threatens human and livestock health, so means safely and effectively should be taked to process sick dead pig.At present, the conventional hand method of process sick dead pig has: (1) burning method, and the method can produce toxic and harmful, contaminate environment, and energy consumption is large, causes the wasting of resources; (2) landfill method, this method floor space is large, and after sick dead pig corruption, obnoxious flavour is emerged and fluid seepage, and meeting polluted air, soil and groundwater, bring potential safety hazard to nearby residents; (3) traditional fermentation process, this method utilizes the mixtures such as wooden chaff, sawdust, stalk as fermentation material, carries out compost to sick dead pig.This method needs to build fermentation vat, and cost is high, long processing period, and fermenting process produces smell pollution.
In recent years; the process of sick dead pig trends towards economic environmental protection; full automatic mechanical operation instead of manual operation; name is called " one die of illness poultry anhydration and incineration pyrolysis system and technique thereof "; application number is the application for a patent for invention of 201510320719.8, discloses a kind of poultry anhydration and incineration pyrolysis system and technique thereof of dying of illness.This system is made up of drying machine, incinerator, charcoal pyrolysis oven and exhaust gas processing device.During operation, poultry of dying of illness is sent into chopping mechanism and the multistage drying machine drying-granulating shattering device by e Foerderanlage, the mummification of drying machine gained die of illness poultry one tunnel send into incinerator burn, pyrolysis oven pyrolysis is sent on another road, the high-temperature tail gas produced after incinerator burns directly sends into drying machine, the charcoal made after pyrolysis oven pyrolysis enters exhaust gas processing device as sorbent material, the byproduct that pyrolysis oven produces sends into incinerator, tail gas one tunnel that drying machine produces returns incinerator, and exhaust gas processing device is sent on another road.This invention whole plant seals, and energy consumption is low, treatment process environment protection health, but occupation area of equipment is large, and equipment cost is high.Therefore, invent a kind of full automatic mechanical, cost low, efficient sick dead pig harmless environmental protection treatment process is necessary.
High temperature degradation technology refers to and utilizes thermophilic bacteria to degrade to poultry of dying of illness under the high temperature of 60-80 DEG C by the fermentation method that improvement is traditional.This method treatment time is short, energy consumption is low, realize resource rationally recycles, and has good promotion prospect.
Summary of the invention
The object of this invention is to provide a kind of sick dead pig harmless environmental protection treatment process;
The object of the invention is by following technical scheme realize:
