Embodiment Construction

[0028] Choose from Bacillus megaterium, Candida lipolytica, and Pseudomonas. Use beef extract 3g, peptone 10g, NaCI 5g, agar, water 1000mL to prepare Pseudomonas slant medium; use glucose 10g, NaCI0.3g, MgSO 4 0.3g, MnSO 4 0.03g, CaCO 3 1.0g, (NH 4 ) 2 SO 4 0.5g, KCl 0.3g, FeSO 4 0.03g, lecithin 0.2g, yeast powder 0.5g, agar, water 1000mL, prepare Bacillus megaterium slant medium; use soybean sprouts 100g, glucose 20g, water 1000mL, agar, wash the soybean sprouts, add water and boil for 30min. Filter with gauze, add agar to the filtrate, add sugar after heating to dissolve, stir to dissolve it, make up water to 1000mL, and prepare Candida tropicalis slant medium. Pseudomonas, Candida lipolytica, and Bacillus megaterium were respectively transferred to fresh slant medium, and cultured at 30°C for 24 hours to obtain activated strains. The activated strains were respectively put into the agar-free medium, the inoculum size was 2%, and they were all cultured at 30° C. for 1...

Abstract

The invention relates to a method for producing liquid organic bacterial manure by utilizing the waste liquor of restaurants and kitchens. The method comprises the following steps of: selecting bacillus megaterium, candida lipolytica and pseudomonas; preparing a pseudomonas slope culture medium, a bacillus megaterium slope culture medium and a candida tropicalis slope culture medium; conveying the pseudomonas, the candida lipolytica and the bacillus megaterium into the fresh slope culture mediums respectively, and culturing at the temperature of 30 DEG C for 24 hours and activating; putting the activated strains into a culture medium in which agar is removed respectively, and culturing at the temperature of 30 DEG C for 18 hours at the rotation speed of 180 revolutions / minute of a shaker to obtain activated bacterial liquid, wherein the inoculation amount is 2 percent; inoculating the activated bacterial liquid of the pseudomonas, the bacillus megaterium and the candida lipolytica into the rubbish waste liquor of restaurants and kitchens in a ratio of 1:1:1, wherein the inoculation amount is 2 percent; adding 60 percent excrement, which serves as auxiliary materials, of livestock and poultry to prepare culture expanding bacterial liquid; and fermenting the compounded bacterial liquid at the temperature of 30 DEG C for 72 hours to obtain the liquid organic bacterial manure.

Description

technical field [0001] The invention relates to the field of regeneration and utilization of waste resources, in particular to a method for producing liquid organic bacterial fertilizer by using kitchen waste liquid, which includes a strain expansion system. Background technique [0002] The COD of kitchen waste liquid can reach up to 100,000 mg / L, which belongs to high-concentration organic wastewater. If it is discharged into water bodies, it will cause serious eutrophication problems, and the cost of treating it to meet the discharge standards is very high. Therefore, using kitchen waste liquid rich in organic components as a nutrient solution to produce liquid bacterial fertilizer through microbial expansion can not only eliminate wastewater discharge, but also realize a high degree of resource utilization of waste liquid. [0003] Bacterial fertilizer is a common name for compound biological fertilizer, which is a biological fertilizer made by artificially cultivating c...
