Embodiment Construction

[0020] Below in conjunction with specific embodiment, the present invention is described further. It should be understood that the following examples are only used to illustrate the present invention but not to limit the scope of the present invention.

[0021] A comprehensive recovery and utilization process of branches and leaves in cities is characterized in that the collected branches and leaves garbage are first classified into three categories: leaves, branches, dead branches and leaves, and weeds.

[0022] (1) Leaf waste is made into animal feed

[0023] (a) drying leaves such as elm leaves and poplar leaves collected at 80°C to 120°C to remove moisture, and then pulverizing;

[0024] (b) Mix 85% leaves with a ratio of 15% concentrate, the concentrate is composed of corn flour, wheat bran, oil residue, wherein the proportion of corn in the mixture composed of leaves and concentrate is 5% , the proportion of wheat bran is 5%, and the proportion of oil residue is 5%;

Abstract

Disclosed is a process for comprehensively recycling urban tree branches and leaves. The process is characterized in that firstly, the collected tree branches and the collected leaves are sorted, and leaf rubbish is made into animal feed; the leaf rubbish is dried at 80 DEG C-120 DEG C and then smashed, the smashed leaf rubbish and concentrated feed which is composed of corn, wheat bran and oil residues according to proportioning are evenly mixed and then subjected to granulation and drying to prepare the animal feed; and tree branch rubbish is carbonized into carbon products, the tree branches with diameters of over 3cm are directly carbonized and activated by steam to be made into wood charcoal. Deadwood branches, dead leaves and straw rubbish are made into organic fertilizers, the deadwood branches, the dead leaves, plant ashes and the tree branch rubbish which are produced during trimming of lawns and flowers are carbonized into charcoal powders produced in the process of carbonization, and animal manure is matched for mixed fermentation to obtain carbon based organic fertilizers.

Description

technical field [0001] The invention relates to a comprehensive recovery process of garbage, in particular to the recovery and utilization of urban trees, branches and leaves, and belongs to the technical field of chemical industry. Background technique [0002] In order to beautify the city, the streets of the city are full of trees, flowers and plants. Sanitation workers need to trim the branches and clean the leaves frequently. Especially in autumn and winter, there will be a lot of leaves and dead branches of flowers and plants. Usually these branches and leaves are cleaned by the sanitation workers. After cleaning, it is loaded and transported away, and incinerated in between. Incineration not only wastes resources but also pollutes the environment. [0003] The invention with the Chinese patent publication number CN1208723 discloses a production method of organic-inorganic compound fertilizer. Disinfect at a temperature of -100°C, and then mix it with nitrogen fertil...
