Embodiment 1

[0034] A solid waste biological treatment technology based on vermiculture, comprising the following steps:

[0035] (1) The collected sludge, cow dung and other livestock and poultry manure, straw, humic acid, and other domestic waste are 50% by weight of sludge, 20% of cow dung and other livestock and poultry manure, 20% of straw, humic acid 5% and other solid waste 5% are mixed and crushed to obtain the base material;

[0036] (2) By adjusting the proportion of each component of the base material, the mass ratio of C / N is 20%, the water content is 32%, the pH is 6.5, and the particle size is 1mm, and then the stacking is carried out, and the temperature is controlled at 42°C , the time is 20 days, and the base material after stacking is obtained;

[0037] (3) carry out ridge making with the base material after above-mentioned composting, 1.2 meters high, wide 2 meters, obtain the base material after making ridge; Fermentative bacteria are inoculated with the base material ...

Embodiment 2

[0040] A solid waste biological treatment technology based on vermiculture, comprising the following steps:

[0041] (1) The collected sludge, cow dung and other livestock and poultry manure, straw, humic acid, and other domestic waste are 60% by weight of sludge, 20% of cow dung and other livestock and poultry manure, 15% of straw, and humic acid 4% and 1% of household waste are mixed and crushed to obtain the base material;

[0042] (2) By adjusting the proportion of each component of the base material, the mass ratio of C / N is 21%, the water content is 34%, the pH is 6.5-7.5, and the particle size is 1.5mm, then stacking and temperature control At 47°C, the time is 23 days to obtain the base material after composting;

Abstract

The invention discloses solid waste biological treatment technology based on earthworm breeding. The invention discloses a method for treatment of sludge and solid waste and the like through earthworm breeding in combination with harmless biological treatment so that contents of nitrogen, phosphorus, potassium, amino acid, crude proteins and other nutrients can be improved after bio-fermentation technology and earthworm coelomic digestive treatment. Therefore, a large number of harmful substances and heavy metal content (lower than an NY 525-2012 agricultural industry standard), earthworm cats are raw material for organic fertilizers with high quality. Raw material is low in cost. Process is simple and easy to master. The purpose of eco-environment protection is fulfilled. The technology belongs to circular economy which is an industry greatly supported by China. The technology is suitable for scale production and promotion.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a solid waste biological treatment technology based on earthworm breeding. Background technique [0002] In recent years, due to the large amount of unreasonable application of chemical fertilizers and chemical pesticides, it not only consumes a lot of non-renewable resources, but also destroys the soil structure, pollutes the quality of agricultural products and the environment, and affects the health and survival of human beings. Therefore, from the perspective of the development trend of green agriculture and ecological agriculture advocated in modern agricultural production, pollution-free organic fertilizers that do not pollute the environment will definitely play an important role in future agricultural production. [0003] In addition, crop straw is an available renewable resource. Based on the advantages of local rich crop straws, the company actively de...
