Integrated recycling and utilization technology of urban tree branches and tree leaves

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...
