NOVELTY - A system for gradually adjusting and controlling solid waste combined compost comprises kitchen waste material storage device (1), adjusting material tanks (2,3), waste gas collecting and processing device (4), mixing agitator (5), compost product storage device (6), reuse compost product storage device (7), compost reaction bucket (8), ventilating device (9), percolate collecting device (10), air distribution plate (11) and crop waste material storage device (12).    USE - As system and method for gradually adjusting and controlling solid waste combined compost (claimed).    ADVANTAGE - The system and method utilizes industrial waste; improves microbial activity; shortens the compost stabilizing time; and improves the degrading efficiency of combined compost of the kitchen waste and the crop waste.    DETAILED DESCRIPTION - A system for gradually adjusting and controlling solid waste combined compost comprises kitchen waste material storage device (1), adjusting material tanks (2,3), waste gas collecting and processing device (4), mixing agitator (5), compost product storage device (6), reuse compost product storage device (7), compost reaction bucket (8), ventilating device (9), percolate collecting device (10), air distribution plate (11) and crop waste material storage device (12). The kitchen waste material storage device is orderly connected with the compost reaction bucket, the compost product storage device and the reuse compost product storage device. The crop waste material storage device is orderly connected with the compost reaction bucket, the compost product storage device and the reuse compost product storage device. The ventilating device is connected with the adjusting material tanks, the waste gas collecting and processing device, the ventilating device and the percolate collecting device, respectively. An INDEPENDENT CLAIM is included for method for gradually adjusting and controlling solid waste combined compost involving classifying the solid waste into the kitchen waste material storage device and the crop waste material storage device; taking a part of kitchen waste and the material from the crop waste material storage device according to the ratio of 2-3 to 1 from the kitchen waste material storage device, adding it to the compost reaction bucket to mix uniformly; providing the air distribution plate under the compost reaction bucket, generating percolate to collect by the percolate collecting device, leading the air to the compost reaction bucket from the ventilating device, and processing the discharged waste by the waste gas collecting and processing device; sampling the sample once after 12 hours in the composting process, detecting multiple indexes such as degrading rate and pH, turning over, where the sampling time of each time is equal; gradually adding different quantities of adjusting agent fly ash and plant ash to the compost reaction bucket from the adjusting material tank at the composting stage, gradually adding different quantities of adjusting agent monopotassium phosphate and ferrisulfas to the compost reaction bucket from the adjusting material tank at the composting rear stage; adding adjusting agent to mix the material by the mixing agitator; transferring the compost product to the compost product storage device, transferring a large part of product, and transferring the other part of compost product to the compost product storage device as the inoculum for subsequent composting.    DESCRIPTION OF DRAWING(S) - The figure shows system for gradually adjusting and controlling solid waste combined compost.
