Trench type composting method for treating breeding sewage and solid wastes simultaneously

The invention discloses a trench type composting method for treating breeding sewage and solid wastes simultaneously, which is used in the field of breeding waste treatment. The trench type composting method comprises the steps of collecting the breeding sewage of farms in a closed sewage pool via a concealed conduit, and colleting the solid wastes in a composting workshop near the sewage pool; leading the breeding sewage to a composting system by a water pump; adjusting the proportion of solid wastes to breeding sewage to auxiliary materials in the composting system, enabling the carbon nitrogen ratio to be (25-30):1 and water content to be 50-60%, moving the materials into a composting trench to undergo aerobic composting, and meanwhile, enabling the water pump to work to pump the breeding sewage in the sewage pool into the composting trench via a spray pipe above the composting trench; turning the breeding sewage and solid wastes in the composting trench, simultaneously aerating the composting trench via aeration openings formed at the bottom of the composting trench, exhausting the waste gases generated in the composting trench via a draught fan after collecting the waste gases, and carrying out dedusting and deodorization treatment. According to the invention, simple sewage treatment is changed into resource utilization of all breeding wastes, so that breeding waste treatment pressure is greatly reduced.
