USE - The method is useful for dry and wet processing of fermented straw.    ADVANTAGE - The method recycles the kitchen waste resources and also guarantees the disposal of wastes harmlessly; and prevents the propagation of bacteria and viruses, and thus it guarantees an environmental-friendly straw waste processing.    DETAILED DESCRIPTION - Dry and wet processing of fermented straw, comprises (i) kneading the straw by a kneading device, crushing the straw to 14-16 meshes, and pouring into a sealed reaction tank of a blasting device, then passing the straw into a saturated water vapor, boosting at a pressure of 2.2-3 MPa, preferably 3 MPa, then starting the reaction time, when it is reacted for 15-21 minutes, placing a valve at the bottom of the sealing reaction tank, soaking and stirring the processed straw which is transferred from the reaction tank to a oval pre-soaking pool by a sealed conveying channel, where the center of the bottom of the pre-soaking pool is uniformly provided with multiple vertical spiral stirring rods, and comprises tap water and livestock excrement in a weight ratio of 3:1.4, and stirring for 8 minutes for every 2 hours with directional stirring; (ii) fermenting completely the soaked and the stirred straw solution of the step (i) using a circulating coupling fermentation tank, carrying out fermentation for 7-9 hours, preferably 8 hours, where the circulating coupling fermentation tank is provided with a solid fermentation reactor, and two gas circulating machines, where one of the gas circulating machine is installed on the upper part of the solid state fermentation reactor by an air pipe and is connected at the bottom of the air inlet of a greenhouse port or greenhouse, and the other gas circulating machine is mounted at the lower part of the solid state fermentation reactor by a pipeline, and one port of the pipeline is connected to two air pipes of the three air distribution pipes of the solid fermentation reactor and the other port is connected on the upper part of the exhaust port of the greenhouse port or greenhouse, where the bottom central part of the solid fermentation reactor is uniformly arranged with multiple activated carbon adsorption column; (iii) coagulating the fermented product obtained after the initial solid-liquid fermentation in the step (ii), and initially filtering the sludge to obtain coagulating water, processing the coagulated water by passing into two section of an aerobic biological treatment device, whose front section is a biological acidification section, where the biological acidification is carried out under anoxic condition, the back section is a contact oxidation section, and the volume ratio of the two sections is 2:2-3, the biological acidification of the front section and the back section are carried out at a pH of 7.3-7.5, with a water temperature of 15-20 degrees C, and the retention time is 3-5 degrees C, and then digesting the coagulated water in an aerobic biological fluidized bed, then degrading the digested water in a flow separating ball, and finally surrounding aerobic biological fluidized bed and flow separating ball device on the outer side if the solid-liquid separating device for solid-liquid separating, to obtain the purified water and sludge; (iv) anaerobically digesting the obtained water and sludge in the step (iii) in an anaerobic digester, where the anaerobic digestion treatment process utilizes a heat balancing circulating system device which ensures the required temperature controlled at 25-27 degrees C, preferably 26 degrees C, to obtain acidification liquid pump, and then transferring into anaerobic fermentation tank, carrying out anaerobic fermentation at 20-23 degrees C for 4-6 days for producing biogas, biogas residue and biogas slurry; and (v) after separating the biogas by gas-liquid separation in the step (iv), transferring into a desulfurization tower for desulfurization after recycling, where during the desulfurization treatment the hydrogen sulfide is converted into an elementary substance sulfur or sulfate.
