Embodiment 1

[0027] The method for preparing sewage denitrification carbon source by compounding rotten fruits and vegetables is implemented according to the following steps:

[0028] (1) Five kinds of rotten fruits and vegetables, including bananas, grapes, apples, green vegetables and lettuce, were taken from a fruit and vegetable market in Shanghai, washed with deionized water, peeled and cut into pieces, and then dried in a vacuum oven at 35°C for 36 hours to obtain Cleaner small pieces of fruit and vegetable materials;

[0029] (2) Take 80g of five kinds of fruit and vegetable pieces whose mass percentage content is 60% of banana, 15% of grape, 15% of apple, 5% of green vegetables and 5% of lettuce, mix with 160g of deionized water and crush for 5min to obtain khaki Paste compound fruit and vegetable carbon source.

Embodiment 2

[0031] The method for preparing sewage denitrification carbon source by compounding rotten fruits and vegetables is implemented according to the following steps:

[0032] (1) Five kinds of rotten fruits and vegetables, including bananas, grapes, apples, green vegetables and lettuce, were taken from a fruit and vegetable market in Shanghai, washed with deionized water, peeled and cut into pieces, and then dried in a vacuum oven at 35°C for 36 hours to obtain Cleaner small pieces of fruit and vegetable materials;

[0033] (2) Take 80g of five kinds of fruit and vegetable pieces whose mass percentage content is 60% of banana, 10% of grape, 10% of apple, 10% of green vegetables and 10% of lettuce, mix with 160g of deionized water and crush for 5min to obtain khaki Paste compound fruit and vegetable carbon source.

Embodiment 3

[0035] The method for preparing sewage denitrification carbon source by compounding rotten fruits and vegetables is implemented according to the following steps:

[0036] (1) Five kinds of rotten fruits and vegetables, including bananas, grapes, apples, green vegetables and lettuce, were taken from a fruit and vegetable market in Shanghai, washed with deionized water, peeled and cut into pieces, and then dried in a vacuum oven at 35°C for 36 hours to obtain Cleaner small pieces of fruit and vegetable materials;

[0037] (2) Take 80g of five kinds of fruit and vegetable pieces whose mass percentage content is 50% of banana, 15% of grape, 15% of apple, 10% of green vegetables and 10% of lettuce, mix with 160g of deionized water and crush for 5min to obtain khaki Paste compound fruit and vegetable carbon source.

Abstract

The invention relates to a method for preparing a composite fruit and vegetable carbon source by compounding rotten fruits and vegetables and application. The preparation method comprises the following steps: 1) respectively cleaning various rotten fruits and vegetables, peeling and dicing, and then drying to obtain various small fruit and vegetable block materials; and 2) mixing a plurality of fruit and vegetable small block materials with water, and then squeezing and crushing to obtain the composite fruit and vegetable carbon source which is used as a sewage denitrification carbon source. Compared with the prior art, the sewage denitrification carbon source is prepared from rotten fruits and vegetables, the process is simple, the cost is low, the rotten fruit and vegetable large-scale treatment method is provided, carbon source substances in the rotten fruits and vegetables are efficiently utilized, and high economic and social environmental benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of treatment and resource utilization of rotten fruits and vegetables, and relates to a method and application of compounding rotten fruits and vegetables to prepare composite fruit and vegetable carbon sources. Background technique [0002] With the acceleration of my country's urbanization process and the continuous improvement of the level of industrialization, the output of various types of garbage in cities and towns is increasing day by day. With the continuous improvement of people's living standards, the proportion of perishable organic waste in the total domestic waste is getting higher and higher. Among them, fruits and vegetables are the main components of perishable organic waste, and their consumption and accumulation are huge. It will cause fruits and vegetables to rot, produce a large amount of volatile organic substances to pollute the environment, and may even cause problems such as the spre...
