Embodiment 1

[0020] (1) Propagation of bacterial strains: prepare 30 sterilized slant surfaces of beef extract peptone test tube culture medium, transfer 20 parent species of Bacillus siamese and 10 parent species of Staphylococcus carnosus for expansion and cultivation, and obtain new Siamese Bacillus parent species and Staphylococcus neocarnus parent species;

[0021] (2) Cultivate the original species: Prepare 3000 mL of beef extract peptone liquid medium, pack it into 15 500 mL triangular flasks, seal and sterilize it for later use, each bottle is 200 mL, use 5 of the above-mentioned Bacillus neosiamese parent species, and inoculate 10 bottles In the beef extract peptone liquid medium (one parent species can inoculate 2-5 bottles), use 2 of the above-mentioned Staphylococcus neocarnus parent species to inoculate in 5 bottles of beef extract peptone liquid medium, all placed at a speed of 160 rpm Minutes, cultured on a shaker at a temperature of 28°C for 72 hours, and the original speci...

Embodiment 2

[0027] The difference between this Example 2 and Example 1 is that the culture conditions of the original species in step (2): 72 hours on a shaker with a rotating speed of 180 rpm and a temperature of 26°C; The inoculum size on the substratum is 3%, and the wheat bran water content is 45%; Step (4), waste liquid pH is 6.8, and the addition weight ratio of bean cake powder and molasses in waste liquid in waste liquid is 7%; Heating temperature The temperature is 85°C, and the disinfection time is 10 minutes; the aeration and aerobic fermentation time in step (5) is 6 days; in the above-mentioned liquid microbial fertilizer, the organic matter is 80g / L, the total nutrient is 65g / L, and the total number of functional bacteria (cfu) 220 million / g.

Embodiment 3

[0029] The difference between this Example 3 and Example 1 is that the culture conditions of the original species in step (2): 72 hours on a shaker with a rotating speed of 150 rpm and a temperature of 26°C; The inoculum size on the substratum is 8%, and the wheat bran water content is 52%; Step (4), waste liquid pH is 7.0, and the addition weight ratio of bean cake powder and molasses in waste liquid in waste liquid is 10%; Heating temperature It is 83 ℃, and the disinfection time is 20min; the aerobic aerobic fermentation time in the step (5) is 7 days; in the above-mentioned liquid organic bio-fertilizer, organic matter is 85g / L, total nutrient is 68g / L, and the total number of functional bacteria viable bacteria (cfu ) 240 million / g.

[0030] The present invention prepares kitchen waste waste liquid into liquid microbial fertilizer through the above method. The Bacillus siamese selected in the present invention can degrade high-concentration organic nutrients, absorb and u...

Abstract

The invention discloses a method of recycling kitchen waste effluent and relates to the technical field of resource recycling. The method includes the steps of adjusting pH of waste effluent to 6-8, adding soybean cake powder and molasses, heating to 80 DEG C and above to obtain a pretreated fermentation liquor; lowering the temperature of the pretreated fermentation liquor to 32 DEG C and below,adding a Bacillus siamensis agent and a Staphylococcus carnosus agent into the pretreated fermentation liquor, carrying out ventilated aerobic fermentation, and applying a fermentation product as a liquid microbial fertilizer to agricultural planting. The method has the advantages that the whole process is free of fouling odor, the liquid microbial fertilizer meets the national standard of microbial fertilizers, contains massive free amino acids and polypeptide ingredients, is more helpful for direct absorption by crops, can promote quick germination of seeds and development of roots, allows crops to mature early, and has a significant biocontrol function.

Description

technical field [0001] The invention relates to the technical field of resource recovery and utilization, in particular to a method for recycling and utilizing waste liquid from kitchen waste. Background technique [0002] "Food waste is also commonly known as "swill" by ordinary people. It is easy to rot and deteriorate, emits a foul smell, and spreads bacteria and viruses. Before the standard treatment of food waste, it was purchased by private individuals. One was used by surrounding farmers to feed pigs , which will cause food homology hazards. Since food waste contains various animal meat, if it is used as feed, cannibalism can easily cause foot-and-mouth disease and various diseases, which will spread to humans and cause harm; Illegal recovery and refining of gutter oil, which is returned to the dining table through underground sales channels, has a serious impact on food safety and poses a great threat to the health of citizens; third, feces, sewage and stench have se...
