[0078] fifthly, after the dead animals or household waste 16 is delivered into the multifunctional boiler 19 and the incineration door 17 is closed, the operator presses an incineration button, so that the air feeder 18 is started, the burner 21 is started if the operator presses a fast incineration button, the operator presses a burner stopping button after incineration to enable the burner to be stopped, a program can also be configured in the control system for timing of the fast incineration, such that the burner 21 is set to be automatically turned off when a timing time being set is reached; and

[0079] sixthly, a data gateway is in communication with a controller, key data in the controller and the operation state of the system are sent to a cloud-end server or remote server 4 through the data gateway, a demander of relevant data logs into the cloud-end server or remote server 4 by means of digital authentication and reads relevant data and reports, users and equipment manufacturers provide well-planned services in advance according to equipment anomaly and alarm information, and can also upgrade or improve equipment according to data statistics, and relevant government departments can determine the incineration amount of dead pigs, household waste and straw for serving as the basis of relevant management according to a complete evidence chain composed of image data, delivery speed of the automatic straw fuel delivery unit 22, the state of the burner 21, and boiler temperature data reports from before and after dead pigs or household waste 16 is put in.

[0080] (11) as shown in FIG. 1, for excretion waste of the pig farm adopting the technology of manure cleaning by urine submerging, animal waste in the raw manure pit for manure cleaning by urine submerging 2 is lifted to a feed inlet of the solid-liquid separation unit 1 through the delivery unit 3 for solid-liquid separation first, solid generated by the solid-liquid separation unit 1 is delivered to the solid material bin 5 to be stored and then is quantitatively fed into the solid high-temperature aerobic fermentation reactor 10 by a solid material delivery unit 6 to be fermented according to technological requirements, solid fertilizers obtained after fermentation are delivered to a solid organic fertilizer semi-finished product bin 13 to be stored, the solid organic fertilizer semi-finished product delivery unit 11 takes charge in lifting and truck loading, and then the solid fertilizers are moved away by a transport vehicle 12; liquid generated by the solid-liquid separation unit 1 is delivered to the liquid high-temperature aerobic fermentation reactor 28 to be fermented, and liquid obtained after fermentation is delivered to a liquid fertilizer pit 26 through an underflow pump 27 to be stored, and then loaded in a tank car through a sewage immersible pump 29.

[0081] (12) as shown in FIG. 2, carbon-containing auxiliary materials are properly added to dry collection manure of a livestock and poultry farm, the carbon-containing auxiliary materials include but are not limited to sawdust, fungus bran, incineration residues, ash and the like, and a manure and auxiliary material mixture is delivered to a drum type solid high-temperature aerobic fermentation reactor 206 to be fermented after the moisture content of the mixture is reduced to 55-80%; the higher the moisture rate of the manure and auxiliary material mixture is, the longer it takes for water evaporation during fermentation in the drum type solid high-temperature aerobic fermentation reactor 206, and therefore, by reducing the moisture content of the mixture to 55% by means of auxiliary materials as much as possible according to the cost of the auxiliary materials, fast fermentation can be achieved.

[0082] (13) dry collection manure of a raw dry collection manure pit 201 and materials in a first auxiliary material bin 203 or a second auxiliary material bin 204 are mixed in a certain proportion under the control of a feeder 205, and then are delivered into the drum type solid high-temperature aerobic fermentation reactor 206 through the screw conveyer 202 to be fermented; organic fertilizer semi-finished products obtained after fermentation are discharged into the solid organic fertilizer semi-finished product bin 13 to be stored through an outlet of the drum type solid high-temperature aerobic fermentation reactor 206, the solid organic fertilizer semi-finished product delivery unit 11 takes charge in lifting and truck loading, and then the organic fertilizer semi-finished products are moved away by the transport vehicle 12 for deep processing or direct use.

[0083] (14) residues left after incineration of dead animals and household waste by the boiler, and ash generated after straw burning are delivered to the solid high-temperature aerobic fermentation reactor 10 and the drum type solid high-temperature aerobic fermentation reactor 206 to be mixed with livestock and poultry manure and fermented, so that solid organic fertilizers are produced to be used for fertilization or soil improvement.

[0084] (15) liquid generated by the solid-liquid separation performed on the excretion waste of a pig farm adopting the technology of manure cleaning by urine submerging by the solid-liquid separation unit 1 is delivered to the liquid high-temperature aerobic fermentation reactor 28 for high-temperature fermentation, so that pathogenic bacteria, eggs and plant seeds are killed, and macromolecules in the liquid are decomposed into stable micromolecules which cannot cause seedling burn, and then the liquid can be used for drip irrigation, sprinkling irrigation and the like as a liquid organic fertilizer.
