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) Leaves waste made into animal feed

[0023] (a) Dry the collected elm leaves, poplar leaves and other leaves at 80°C-120°C to remove water, and then crush them;

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

Abstract

The present invention discloses an integrated recycling and utilization technology of urban tree branches and tree leaves. The technology is characterized in that firstly collected tree branch and tree leaf waste is classified; the tree leaf waste is made into an animal feed: the tree leaf waste is dried at a temperature of 80 DEG C to 120 DEG C, the dried tree leaf waste is crushed, the crushed tree leaf waste is mixed evenly with a concentrate feed composed of corn, wheat bran and oil residues, the mixture is granulated, and the granulated mixture is dried into the animal feed; the tree branch waste is carbonized into charcoal products: the tree branches with a diameter of 3 cm or more are directly carbonized, the carbonized tree branches are activated by steam, and the activated tree branches are prepared into charcoal; and the tree branches at a diameter of 3 cm or below are crushed, the crushed tree branches are dried, the dried tree branches are prepared into semi-finished woodenstrips, then the wooden strips are carbonized, the carbonized wooden strips are activated by steam, and the activated wooden strips are dried to prepare the charcoal; and the wastes of withered branches and leaves, and weeds are prepared into an organic fertilizer: the wastes of withered branches and leaves produced by trimming lawns, flowers and plants, plant ash, and charcoal powder produced bythe process of carbonizing the tree branch waste into charcoal products are combined with animal manure for mixed fermentation, and the fermented mixture is prepared into a charcoal-based organic fertilizer.

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 Chinese Patent Publication No. CN1208723 discloses a production method of organic-inorganic compound fertilizer. The technical key is: after the organic matter such as stalks, weeds, leaves or fruit shells of v...
