1. the low technique that drops into environmental protection treatment feces of livestock and poultry rapid production of organic fertilizer is characterized in that, comprises the steps:

  • (1) specifically comprises following operation;

    (1-1) whole ground or level land, (1-2) spread loess or brick, (1-3) according to the area of make out the scale disposal field;

    year industrial scale is needing the 400-600 square meter below 1000 tons, and year industrial scale is needing the 600-900 square meter more than 1000 tons, below 3000 tons;

    Set up the rainproof facility of energy;

    (1-4) hold the ditch of arranging rainwater successfully at the disposal field periphery;

    (2) feces of livestock and poultry is processed, and specifically comprises following operation;

    (2-1) will pending feces of livestock and poultry as feedstock delivery to the processing place and spread out;

    (2-2) in raw material, add auxiliary material;

    (2-3) spray the biological fermentation microbial inoculum;

    (2-4) with the equipment of stirring auxiliary material and feces of livestock and poultry being drawn ditch mixes;

    (2-5) closed processes place makes feces of livestock and poultry deodorizing in the disposal field, fermentation, drying;

    (2-6) open the closed processes place, the operation of repeating step (2-4) and step (2-5);

    After (2-7) water content of handled thing drops to below 50% in the pending place, with artificial or turn over the equipment of revolving with its heap heap, fermentation;

    (2-8) measurement temperature;

    after fermenting 1-3 days, carry out the temperature survey of fermentation heap material, record every day;

    (2-9) turning;

    when the temperature of fermentation heap material reaches 65-70 degree centigrade, carry out artificial or mechanical turning operation;

    (2-10) operation of repeating step (2-8) and step (2-9) until the fermentation heap temperature of charge is basicly stable, is carried out next step operation after no longer rising to more than 65 degrees centigrade again;

    (2-11) ted;

    with artificial or machinery heap is split into thickness less than or equal to 20 centimetres thin layer, with the artificial or machinery stroke ditch of stirring, makes its water content drop to 25wt%-30wt%;

    (3) sampling detects, and according to the sampling of NY525-2002 standard and detect, carries out subsequent operations after qualified;

    (4) crush and screen, sampling is detected qualified work in-process pulverize, sieve, enter semifinished product warehouse;

    (5) secondary fermentation;

    the work in-process stacking of water content being down to 25-30wt% is in heaps, carries out secondary fermentation, rainwater-proof;

    (6) packing, sealing, code heap;

    (7) get on the bus and dispatch from the factory, with packaged product loading, dispatch from the factory.
