Embodiment 1

[0033] The technological process of the tail vegetable aerobic humification method of adding the river bottom mud containing high humus in this embodiment is as follows figure 1 As shown, it specifically includes the following steps:

[0034] Step (1): Take the river bottom mud, add a washing agent to remove heavy metals in the river bottom mud, and then dry the washed river bottom mud until the water content is less than 50%, to obtain dry bottom mud;

[0035] Step (2): respectively measuring the total organic carbon, total organic nitrogen and C / N ratio of the dried bottom sludge and the tail vegetables, and then uniformly mixing the dry bottom sludge and the tail vegetables with the nitrogen-enhancing agent, and crushing to obtain a mixed stock;

[0036] Step (3): Put the mixed stock into the humification bin, carry out aerobic humification with forced ventilation, turn the pile every 5 days, and measure the total organic carbon, total organic nitrogen and total humificatio...

Embodiment 2

[0042] Take 10kg of sediment from a certain river in Shanghai, add 10L of 1mol / L rhamnolipid solution, turn over and soak for 24 hours, then filter, and dry in the sun until the water content is less than 50%. Measure the TC (total carbon), TN (total nitrogen) and C / N ratio of the dry bottom sludge and the tail vegetables, then, mix the dry bottom mud and the tail vegetables according to the ratio of 1:5 and crush them to make the particle size of the mixed pile Less than 10 microns, moisture content 60%, C / N ratio 30:1. Add a small amount of superphosphate and mix, put the mixed stock into the large fermentation bin, and carry out aerobic humification by means of continuous ventilation, and turn the stock once every 7 days. The total humic acid content in the fermentation process is measured, and the humified product is obtained when the content of each component is basically stable.

Embodiment 3

[0046]Take 10kg of sediment from a lake in Shanghai, add 10L of 1mol / L citric acid solution, turn over and soak for 24 hours, then filter, and dry in the sun until the water content is less than 50%. Measure the TC (total carbon), TN (total nitrogen) and C / N ratio of the dry bottom sludge and the tail vegetables, then, mix the dry bottom mud and the tail vegetables according to the ratio of 1:5 and crush them to make the particle size of the mixed pile Less than 10 microns, moisture content 60%, C / N ratio 30:1. Add a small amount of superphosphate and mix, put the mixed stock into the large fermentation bin, and carry out aerobic humification by means of continuous ventilation, and turn the stock once every 7 days. The total humic acid content in the fermentation process is measured, and the humic fertilizer is obtained when the content of each component is basically stable.

Abstract

The invention relates to a method for performing aerobic humification on residual vegetable added with high-humus-containing river sediment. The method particularly comprises the following steps: taking river sediment or lake sediment, adding an eluting agent to remove heavy metal, and drying the eluted river sediment or the lake sediment in the sun until the moisture content is less than 50 percent to prepare dry sediment; measuring the total organic carbon, the total organic nitrogen and the C/N ratio of the dry sediment and the residual vegetable separately, mixing the dry sediment, the residual vegetable and a nitrogen-retaining agent uniformly and crushing to prepare mixed stacked materials; putting the mixed stacked materials into a humification warehouse, performing aerobic humification by a forced ventilation mode, turning the pile for once every other 5 to 8 days, measuring the total organic carbon content, the total organic nitrogen content and the total humic acid content in the fermentation process, and ending until the component content value is stable. Compared with the prior art, the method has the advantages that the steps are simple, the economic practicability is high, co-treatment of the river and lake sediment and the residual vegetable is realized, the humification progress is accelerated and the quality of the humic fertilizer is improved.

Description

technical field [0001] The invention belongs to the technical field of resource utilization of organic waste, and relates to a method for aerobic humification of tail vegetables by adding high-humus-containing river bottom mud. Background technique [0002] Tail vegetables refer to the leftover leaves, leftovers and leaves, roots, stems, fruits and a large number of defective vegetables produced during the processing of fresh vegetables during the harvesting, processing, transportation, and sale of fresh vegetables. Like fresh vegetables, tail vegetables are rich in vitamins, minerals, sugars, dietary fiber, organic acids and aromatic substances. In many cities, due to the lack of effective recycling and utilization, there are ecological and environmental problems such as large quantities, large areas, random piles, and random disposal. Therefore, the treatment and resource utilization of agricultural organic wastes such as tail vegetables are important contents of environm...
