Problems solved by technology

In production practice, a kitchen waste bio-drying treatment site with a daily processing capacity of 5 tons (monthly processing capacity of 150 tons) needs to add sawdust at 25%, and needs to add 50 tons of sawdust per month (400 yuan per ton of sawdust, then 20,000 yuan per month); this is unbearable for food waste biological drying treatment sites

Embodiment 1

[0023] The invention discloses a method for synergistic biological drying by using auxiliary materials and recycled materials, in which kitchen waste is dried by a biological drying machine.

[0024] Add 75% of the food waste that the machine can handle into the biological drying machine, and the balance is auxiliary materials; the auxiliary materials include 60% sawdust, and the balance is recycled materials; the recycled materials are left over from the previous batch of biological drying. The material contains 20% sawdust, the balance is food waste, and the moisture content is 15%.

[0025] The heating plate of the biological drying machine is 100°C, and the temperature in the biochemical chamber is 80°C.

[0026] The heating and stirring in the biological drying machine are linked, and the stirring method adopts intermittent stirring. When the stirring stops, the heating stops immediately; at the same time, the positive and negative intervals are alternately rotated when s...

Embodiment 2

[0030] The invention discloses a method for synergistic biological drying by using auxiliary materials and recycled materials, in which kitchen waste is dried by a biological drying machine.

[0031] Add 70% of the food waste processed by the machine into the biological drying machine, and the remainder is auxiliary materials; the auxiliary materials include 80% sawdust, and the remainder is recycled materials; the recycled materials are left over from the previous batch of biological drying. The material contains 15% sawdust, the balance is food waste, and the moisture content is 10%.

[0032] The heating plate of the biological drying machine is 90°C, and the temperature in the biochemical chamber is 60°C.

[0033] The heating and stirring in the biological drying machine are linked, and the stirring method adopts intermittent stirring. When the stirring stops, the heating stops immediately; at the same time, the positive and negative intervals are alternately rotated when s...

Embodiment 3

[0037] The invention discloses a method for synergistic biological drying by using auxiliary materials and recycled materials, in which kitchen waste is dried by a biological drying machine.

[0038] Add 80% of the food waste that the machine can handle into the biological drying machine, and the balance is auxiliary materials; the auxiliary materials include 40% sawdust, and the balance is recycle materials; the recycle materials are left over from the previous batch of biological drying. The material contains 25% sawdust, the balance is food waste, and the moisture content is 20%.

Abstract

The invention discloses a method for conducting synergistic bio-drying with an auxiliary material and a return material. Kitchen waste is dried through a bio-drier, and the kitchen waste with the machine handling capacity being 70%-80% is added into the bio-drier, and the balance is the auxiliary material. The auxiliary material comprises 40%-80% of saw dust, and the balance is the return material. The return material refers to a material left in the previous batch of bio-drying and contains 15%-25% of saw dust, the balance is the kitchen waste and the moisture content is 10%-20%. By adoptionof the method, the return material is recovered and reconstituted into the auxiliary material with the saw dust to be subjected to synergistic bio-drying, the bacterium quantity in a pile body can beeffectively increased, the temperature of the pile body can be better increased, the moisture content of the pile body can be lowered more quickly, and energy consumption is reduced while quick synergistic bio-drying is achieved.

Description

technical field [0001] The invention relates to the technical field of solid organic waste treatment, in particular to a method for synergistic biological drying using auxiliary materials and recycled materials. Background technique [0002] Food waste is one of the main urban organic wastes in my country, with an annual output of about 90 million tons. If such a large amount of food waste is not disposed of in time, it will have adverse effects on the production and life of residents. Compared with treatment technologies such as aerobic composting, the biological drying treatment cycle is shorter, generally 7 to 15 days. However, with the increasing requirements of municipal management on the processing cycle of urban kitchen waste, ordinary biological drying has been unable to meet the rapid treatment of kitchen waste. In recent years, there are mainly biological drying processors with heating function on the market with a daily processing capacity of 1 ton, 3 tons, 5 ton...
