(1) Sorting waste vegetable leaves;
(2) crushing, dehydrating, drying and crushing the selected non-corrupt vegetable leaves to obtain vegetable leaf feed powder;
(3) crushing and dehydrating the sorted rotten vegetable leaves, adding lignite,
Chicken manure, tobacco powder and fermenting bacteria are made into organic fertilizer;
(4) Sewage flowing out when the vegetable leaves are crushed and pressed flows into a sewage treatment station for treatment, and the sewage
Soil is used as organic fertilizer. By adopting the technical scheme, the waste vegetable leaves are processed into two products, namely vegetable leaf feed powder and organic fertilizer, and the sewage formed in the processing process is purified, thus avoiding environmental pollution.

1. The production process of recycling waste vegetable leaves is characterized by comprising the following four processes:
(1) Sorting of discarded vegetable leaves: sorting rotten vegetable leaves from discarded vegetable leaves manually;
(2) crushing the selected non-corrupt vegetable leaves into 2- 10mm strip fragments; Squeezing and dehydrating the chips to reduce the water content of the vegetable leaves to 50% to 60%; Drying the dehydrated vegetable leaf fragments, and controlling the water content of the dried vegetable leaf fragments to be between 65438 00% and 65438 05%; Pulverizing dried vegetable leaf fragments for the second time, and sieving with a 60-mesh sieve; Packaging the sieved vegetable leaf powder into vegetable leaf feed powder;
(3) The rotten vegetable leaves sorted in the working procedure (1) are crushed into 2- 10mm pieces; Squeezing and dehydrating the chips to reduce the water content of the chips to 50% to 60%;
Adding lignite, chicken manure, tobacco powder and fermenting bacteria into dehydrated rotten vegetable leaf fragments, stirring and mixing uniformly, stacking and fermenting, turning over the fermentation pile when the internal temperature of the fermentation pile is raised to 65-70 DEG C, performing stacking and fermenting again when the temperature of the turned fermentation product is lowered to normal temperature, and fully decomposing the fermentation product after stacking and fermenting for 3-5 times. (4) filtering the sewage grid flowing out when the vegetable leaves are crushed and pressed in the steps (2) and (3), and returning the filtered vegetable leaf fragments to the step (3) to be added into the rotten vegetable leaf fragments; The remaining sewage flows into the sewage treatment station for sewage treatment; The remaining sludge after sewage treatment is extruded and dehydrated, and the dehydrated sludge is returned to the process (3) as an additive of organic fertilizer for composting and fermentation.
There is a set of technology for recycling waste vegetable leaves, and only four processes are needed to produce feed powder and organic fertilizer.
(1) Sorting waste vegetable leaves;
(2) crushing, dehydrating, drying and crushing the selected non-corrupt vegetable leaves to obtain vegetable leaf feed powder;
(3) crushing and dehydrating the sorted rotten vegetable leaves, and then adding lignite, chicken manure, tobacco powder and fermenting bacteria to prepare an organic fertilizer;
(4) Treating the sewage flowing out when the vegetable leaves are crushed and pressed, and using the sludge as an organic fertilizer.
