Embodiment 1

[0044] (1) Raw material self-test: measure the water content and nutrient content of papermaking sludge and corncob, adjust the ratio of papermaking sludge and corncob, so that the C / N of the mixture of papermaking sludge and corncob is 25-29%, The moisture content is 55-65%;

[0045](2) Put the mixture of papermaking sludge and corn cob into the fermentation tank in layers, each layer is 20 cm thick, spray 100 times dilution of EM stock solution on the top of each layer (1 kg of EM stock solution (produced by Henan Tianyi Biotechnology Co., Ltd.) and add water Dilute to make up 100 kg), and spray 100 times dilution of EM stock solution for each layer until the fermentation tank is full (the height of the fermentation tank is 1.2m); then turn the materials in the fermentation tank 3-5 times in the steel frame greenhouse to fully After stirring evenly, carry out aerobic fermentation by blasting oxygen (blowing oxygen for two hours every day); the total amount of the 100-fold di...

Embodiment 2

[0049] The preparation method of described EM stock solution fermentation dilution is: 30 kilograms of EM stock solutions (produced by Henan Tianyi Biotechnology Co., Ltd.) are added 30 kilograms of brown sugars, then add 300 kilograms of waters and dilute, then place anaerobic fermentation in a sealed container ( Ambient temperature 20-35°C), when the pH drops to 3-3.5, and there is a mellow fermentation sour taste, indicating that the fermentation is successful, obtain 360 kg of second-generation EM bacterial liquid; then add 300 kg to the obtained second-generation EM bacterial liquid Dilute brown sugar with 3,600 kg of water, place it in a sealed container for anaerobic fermentation (ambient temperature 20-35°C), wait until the pH drops to 3-3.5, and there is a mellow fermentation and sour taste, indicating that the fermentation is successful, and 4,260 kg of EM stock solution is fermented and diluted Liquid, its product ingredients are compound beneficial microorganisms do...

Abstract

The invention discloses a method for producing an organic fertilizer by treating paper making sludge with microflora. In the method, sludge and auxiliary materials in a paper mill are taken as raw materials for serving as high-quality protein resources of the organic fertilizer, beneficial microbial bacteria are subjected to pure culturing, so that the organic fertilizer which can be absorbed more easily by plants and has quicker acting is produced. Due to the adoption of the method, the problem of environmental pollution caused by the paper mill is solved; and by applying the fertilizer, soil can be remarkably improved, the soil fertility is increased, the growth of plants is promoted, the crop quality is improved, and the absorption of other nutrients by crops is promoted.

Description

technical field [0001] The invention relates to a method for producing organic fertilizer by using microbial flora to treat papermaking sludge, and belongs to the technical field of environmental protection. Background technique [0002] In recent years, my country's paper industry has developed greatly. The output and consumption of paper rank among the top in the world. The increase in the output of the paper industry has led to a rapid increase in the number of pollutants in the production process. Among them, paper sludge is the main pollution of the paper industry. one of the things. Papermaking sludge contains rich organic matter and nutrients such as nitrogen, phosphorus, and potassium, and is a high-quality resource available for development and utilization. However, due to limitations in technology and capital, papermaking sludge is still treated by traditional stacking methods and Burial method is the main method: [0003] 1. The traditional stacking method is to ...
