Problems solved by technology
This method is improved compared with ordinary composting, but the pretreatment steps are more troublesome, and it is difficult to adjust the water content and pH value, and it is easy to generate stench and secondary pollution of waste liquid in the process of precomposting
Moreover, a deodorizing device must be installed separately, which increases the cost and complexity of the process

Embodiment 1
[0034] Take a material box with a length of 60cm, a width of 35cm, and a depth of 20cm as an earthworm ecological treatment device, place it at an angle of 15°, open a water outlet at the lower end, add a 2mm sieve filter to the inner side at 1cm from the edge, and lay a 5cm thick simple decomposed at the bottom. 6kg of cow dung, with a water content of 50%, was inoculated with 5,000 Eisensis worms. On the 3rd day after the inoculation, the upper layer was covered with 5 cm thick garbage picked up from the farmer's market, with a fresh weight of about 6 kg, and the leachate that flowed out was collected at the same time. Turn over the materials in the device after 3 days to check the progress of garbage treatment. Put the same amount of garbage on the 6th day after putting in the garbage for the first time, put in the same amount of garbage for the third time after one week of treatment, and add 5cm thick to the upper layer after another week of treatment. The newly decomposed...

The invention discloses a method for earthworm digestion based ecological treatment of farmer market garbage. The method includes (1) laying a culture medium on the bottom layer, and inoculating earthworms in the culture medium; (2) when two thirds of the culture medium are converted into earthworm casts, laying a layer of farmer market garbage on the upper layer of the culture medium; (3) when the farmer market garbage is completely digested by the earthworms, re-laying a layer of fresh farmer market garbage on the top; (4) repeating for two to five times according to the step (3). The method has the advantages that no special pretreatment is required to be performed on the farmer market garbage, operation procedures are simplified, and treatment efficiency is improved; after treatment, efficient ecological organic fertilizer rich in active microorganisms and high-quality humic acid liquid fertilizer can be produced; during treatment, the earthworm casts produced by the earthworms are utilized for deodorization, an additional deodorization device does not need to be mounted, and cost can be further saved.
Description
technical field [0001] The invention relates to the field of garbage treatment, in particular to a method for ecologically treating garbage in farmers' markets based on earthworm digestion. Background technique [0002] According to reports, currently about two-thirds of cities in China are trapped in garbage siege. The annual output of "urban waste" alone is nearly 150 million tons. The open-air garbage not only affects the urban landscape, but also pollutes the air, water and soil that are closely related to our lives, posing a threat to the health of urban residents. Garbage has become a thorny problem in urban development. Garbage from farmers’ markets is one of the important sources of urban waste. More than 95% of the garbage from farmers’ markets is cabbage leaves and fruit peels, mainly organic components. At present, the treatment of farmer's market waste is mainly based on ordinary composting. The composting method is to process urban waste according to the compo...
