manufacture Embodiment 1

[0018] Manufacture Example 1: Process 100 kilograms of pig blood wastewater:

[0019] 1. Strain preparation: Lactobacillus acidophilus (L.acidophilus) CGMCC 1.1854 and Bacillus cereus (Bacillus cereus) CGMCC AS 1.895 were selected as the strains.

[0020] Preparation of seed liquid: culture medium: 75 grams of brown sugar, 15 grams of peptone, dilute to 3000 ml with blood wastewater, sterilize at 115°C for 20 minutes; add the same amount of the above-mentioned activated bacteria after cooling down, control the temperature at 34±1 Cultivate for 48 hours at ℃ to prepare a compound seed solution;

[0021] 2. Fermentation: put 100 kg of fresh blood wastewater into the fermentation device, add 3 liters of compound seed liquid and stir evenly, control the temperature at 34±1°C, during the cultivation process, stir slowly intermittently, cultivate for 48 hours, and test the pH3.8, Fermentation is terminated; after inspection and packaging, it is microbial fertilizer.

manufacture Embodiment 2

Abstract

The invention relates to the technical field of treatment and comprehensive utilization of animal slaughter industrial wastewater, finds new application of blood wastewater, and provides a microbial fertilizer which is manufactured by taking blood wastewater as a raw material and selecting lactobacillus and bacillus through fermentation. The microbial fertilizer has the advantages of pesticide residues degradation, and can be used for producing nuisanceless agricultural products.

Description

Technical field: [0001] The invention relates to the technical field of treatment and comprehensive utilization of animal slaughter industrial waste water, in particular to the pollution treatment and comprehensive utilization of waste water produced during pig blood processing. Specifically, it is a microbial fertilizer prepared from blood wastewater as a raw material through a microbial fermentation process; the invention also relates to the application of the microbial fertilizer in the field of planting. Background technique: [0002] With the improvement of people's living standards, the consumption of meat is increasing day by day, the production scale of the animal slaughter industry is also expanding, and the amount of animal blood produced is also increasing day by day, and the number of enterprises bidding for processing blood is also increasing. During the blood processing process, a large amount of wastewater will be produced. The wastewater mainly comes from the...
