Abstract

The invention discloses a recycling production process of discarded vegetable leaves, comprising the following four procedures: (1) sorting the discarded leaves; (2) smashing the selected uncorrupted leaves, dehydrating, drying and pulverizing so as to obtain vegetable leaf feed powder; (3) smashing and dehydrating the sorted rotted leaves, and adding brown coal, chicken manure, tobacco leaf powder and zymophyte so as to prepare an organic fertilizer; and (4) processing the sewage which flows out when the vegetable leaves are smashed and extruded in a sewage processing station, wherein the sludge is used as the organic fertilizer. By adopting the technical scheme, the discarded vegetable leaves are processed into two types of products, namely the vegetable leave feed powder and the organic fertilizer; and the sewage formed in the processing process can be prevented from polluting the environment after being purified.

Description

Waste vegetable leaves is recycled production technology
Technical field
The invention belongs to waste vegetable leaves recovery and utilization technology field.
Background technology
In a lot of vegetables places of production, the trade market of vegetables will produce a large amount of abandoned vegetable leaves every day, and these abandoned vegetable leaves are because the value of recycling is lower, and people to the technical research of its recycling seldom also do not form the good treatment technology at present.Usually people use a spot of waste vegetable leaves pasture, but for large batch of discarded dish leaf, owing to wherein contain putrid and deteriorated dish leaf, can not directly use waste vegetable leaves pasture, otherwise cause livestock sick easily; A large amount of waste vegetable leaves is stacked meeting everywhere because of unmanned the recovery, not only wastes, but also causes environmental pollution; In the good city of environmental protection, the abandoned vegetable leaf all is transported to destructor plant and works as garbage disposal every day, causes the huge waste of resource, human and material resources.
Summary of the invention
The present invention is directed in the prior art, the abandoned vegetable leaf lacks the problem of recovery and utilization technology, provides a kind of waste vegetable leaves to recycle production technology, and its technical scheme is following:
A kind of waste vegetable leaves is recycled production technology, and this technology comprises following four operations:
(1) waste vegetable leaves sorting: artificial dish leaf with corruption sorts out from discarded dish leaf;
(2) the not corrupt dish leaf that will select carries out break process, and it is broken into the strip fragment of 2 to 10 millimeters sizes; Fragment is carried out extrusion dehydration handle, the moisture content of dish leaf is dropped between 50% to 60%; Dish leaf fragment to after the dehydration carries out dried, and dried dish leaf fragment moisture content is controlled between 10% to 15%; Dried dish leaf fragment is carried out secondary pulverize, pulverize the back and carry out sub-sieve with 60 purpose screen clothes; Dish leaf powder to sub-sieve comes out is packed, and makes dish leaf feed powder;
(3), the dish leaf that addles that sorts out in the operation (1) is carried out break process, it is broken into the dish leaf fragment that addles of 2 to 10 millimeters sizes; Fragment is carried out extrusion dehydration handle, the moisture content of fragment is dropped between 50% to 60%; Add brown coal, chicken manure, tobacco leaf powder and zymophyte in the dish leaf fragment that addles after dehydration, mix laggard windrow ridge fermentation, when the fermentation heap internal temperature rises to 65-70 ℃; Carrying out turning handles; When turning after fermentation thing temperature is reduced to normal temperature, pile the ridge fermentation once more, after the fermentation of three to five heap ridges; Fermentate fully becomes thoroughly decomposed, and processes organic fertilizer;
(4), above-mentioned operation (2) and operation (3) Chinese food leaf are pulverized and the sewage grid that flows out during extruding is done filtration treatment, the dish leaf fragment that leaches returns and adds in the operation (3) in the dish leaf fragment that addles; Remaining sewage flows into Sewage Disposal and carries out sewage disposal; Mud remaining after the sewage disposal is carried out extrusion dehydration handle, the mud after the dehydration turns back to a kind of interpolation composition that is used as fertilizer in the operation (3) and piles the ridge fermentation process.
The pressure of extrusion dehydration is controlled between the 1Mpa-1.5Mpa in operation (2) and operation (3).
Operation (3) is described to be processed in the raw material of organic fertilizer, and the shared weight portion of each composition is: 25 parts-35 parts in the dish leaf fragment that addles, 25 parts-35 parts in brown coal, 30 parts-40 parts of chicken manures, 5 parts-10 parts in tobacco leaf powder, 0.1 part-0.2 part of zymophyte.
Sewage disposal described in the operation (4) is divided into acidity adjustment, Anaerobic Treatment, aeration processing and denitrogenation processing several steps, wherein:
Acidity adjustment: sewage is put into the acidity adjustment pond, at the bottom of regulating reservoir, place activated sludge, the tracheae of band pore is set above activated sludge, the outer air pump of tracheae connection pool, air pump is inflated to tracheae, and gas sprays from the pore of tracheae, the sewage of stirring;
Anaerobic Treatment: get into anaerobic pond through the sewage after the acidity adjustment, be placed with filler at the bottom of the anaerobic pond, filledly be added with anaerobic bacteria, waste water gets into from the bottom, and flow out on top, and filler is activated carbon or activated sludge;
Aeration is handled: the sewage through Anaerobic Treatment gets into the aeration tank, and aeration head is installed at the bottom of the aeration tank, is filled with activated sludge in the pond, and aeration head is positioned under the activated sludge, aeration head by the pond at the bottom of upwards inflation, stir activated sludge and sewage;
Denitrogenation processing: the sewage of handling through aeration gets into the denitrification reaction pond, at the bottom of the denitrification reaction pond, gas tube is set, and places the coloured glaze ball in the pond in, and the coloured glaze ball is immersed in the sewage, gas tube by the pond at the bottom of upwards air blowing, stir coloured glaze ball and sewage.
The mud of operation in the claim 1 (4) gained is added to when being used as fertilizer in the operation (3), and the weight portion of each composition of fertilizer is: addle dish leaf fragment and mud merge and account for 25 parts-35 parts, brown coal and account for 25 parts-35 parts, chicken manure and account for 30 parts-40 parts, tobacco leaf powder and account for 5 parts-10 parts, biological inoculum and account for 0.1 part-0.2 part.
Adopt technique scheme; Waste vegetable leaves is processed to dish leaf feed powder and two kinds of products of fertilizer; Realize the recycling of waste vegetable leaves, the sewage that in the waste vegetable leaves process, forms can offer field irrigation through after the purified treatment, because the sewage composition that waste vegetable leaves forms is simple; Thereby treatment process is simple relatively when carrying out sewage disposal, and processing cost is lower.
