NOVELTY - Making anaerobic sludge compost fertilizer involves providing anaerobic sludge compost fertilizer preparing device comprising fertilizer tank and temperature adjusting system, where fertilizer tank is equipped with spiral propelling device (11) that is connected with double-direction motor (16), and spiral propelling device is used for controlling positive/negative bidirectional operation so as to realize physical/biological effect of material to form compost; then adding urea, monoammonium phosphate, potassium chloride, calcium superphosphate; stirring; and mixing to obtain fertilizer.    USE - For preparation of anaerobic sludge compost fertilizer (claimed).    ADVANTAGE - The present method is economic, simple, convenient, efficient and environment-friendly; can full use of the water content of sludge, rich nitrogen, phosphorus, and potassium; enhances the practicability of the compost; provides high efficiency and intelligent composting; and shortens the fermentation period.    DETAILED DESCRIPTION - Preparation of anaerobic sludge compost fertilizer involves: (a) providing anaerobic sludge compost fertilizer preparing device, comprising a fertilizer tank and a temperature adjusting system, where the fertilizer tank is provided with a sensor inserting hole (1), a tail gas detecting port (2), a tail gas collecting port (3), skirt (4) and waters collecting groove (5). The waters collecting groove is provided with water outlet (6) and flange gasket (7). The upper part of the fertilizer tank is provided with a feeding port (8) and lower part of the fertilizer tank is provided with a discharging port. The inner side of tank is respectively provided with oxygen probe (9) and a temperature probe (10). The central axis position of tank is equipped with a spiral propelling device (11), and the lower end of the spiral propelling device is connected with a double-direction motor (16), where the spiral propelling device is used for controlling the positive and negative bidirectional operation. The bottom of the tank is placed on the filler, where the filler is set above isolation net. The temperature adjusting system comprises aeration device and a hot water circulating device. The aeration device comprises an air flow regulator (13) and air blower (14), and the hot water circulating device comprises heat preservation layer, a circulating pump, a heating boiler and a hot water circulating pipe, where an insulating layer (19) at the bottom of the pipe through the circulating pump is connected with the heating boiler. The hot water circulation pipe is connected to the heat preservation layer, where the temperature feedback control system controls the aeration device and a hot water circulating device for implementing composting of aerobic work alternately. The stirring temperature feedback and anaerobic sludge compost fertilizer preparing device is set as 1 minute reverse rotation feeding, and feeding for 5 minutes, controlling compost tank volume at 75%, then positive rotating, continuously ventilating at the ventilation rate of 0.4 liter/minute, where the middle layer temperature is lower than 35 degrees C, a adjusting screw propeller stops rotating, stop rotating after starting water bath heat preservation system ratio controlled at 26:1, where the water content is controlled to be 53%; (b) entering the sludge garbage material feeding port into compost tank, starting the air blower and a spiral propelling device, a material for a series of physical and biological effect, that is, while a friction, ferment, the initial fermentation, a fungus in a biological comparison active, is mainly used for perishable organic substance decomposing metabolism and produce heat, at the same time, a friction generating mechanism of the heat roller temperature rapidly increase, operating for 8 hours, lowering the temperature to 65 degrees C that can kill parasite eggs, pathogenic microorganisms and weed seed, and decomposing the organic substance, stabilizing the obtained mixture at high temperature, gradually reducing oxygen and temperature of the mixture, continuously decomposing organic matter and the compost mix, when the temperature is reduced to 30 degrees C, automatically closing the air blower, stopping operating the spiral propelling device, and starting the circulating pump (20), and oxidation of rest of decomposing organic matter, carrying out the process for 15 days, to obtain the compost; and (c) taking urea, monoammonium phosphate, potassium chloride, calcium superphosphate and compost obtained in step (b) compost according to 25:10:10:15:40 proportion into compost tank, forwarding to spiral propelling device, stirring for 15 minutes, opening the discharging opening and starting bidirectional motor, and to obtain anaerobic sludge compost fertilizer.
