Embodiment 1

[0037] For the freeze-dried powder of Lactobacillus QV1 original bacteria of the present invention, rapid propagation and recovery experiments, acid resistance experiments, salt tolerance experiments and high temperature resistance experiments were carried out respectively. It is prepared in the manner of preparing lactobacillus freeze-dried powder.

[0038] a) Rapid propagation and recovery experiment: Put 100 mg of freeze-dried powder of QV1 original bacteria into a beaker filled with 20 mL of warm water at 35-40°C, and put other lactobacillus under the same conditions at the same time (using typical LBF128 lactobacillus as a comparison). LBF128 started to ferment and sour after 30 minutes, while QV1 started to ferment and sour after 5 minutes. This experiment proves that the awakening and reproduction speed of QV1 of the present invention is obviously better than that of general Lactobacillus, so it can rapidly proliferate in the biochemical reaction system in which urine i...

Embodiment 2

[0053] This embodiment processes fresh human excrement and urine in the Pinghu area, and the treatment process includes the following steps:

[0054] 1) Import the feces and urine into the biochemical treatment tank for aerobic biological treatment, and place them in a place with a specific gravity of 0.98-1.02g / cm 3 The biochemical treatment tank filled with polyurethane sponge is regularly added with bacteria liquid containing Lactobacillus QV1 and compound enzyme MD444, and micro-nano aeration treatment is carried out at the same time. The volume of the biochemical treatment tank is 1000L, and the flow rate of micro-nano aeration is controlled to 70L / min. The number of viable QV1 bacteria in the bacterial solution is 500 million cfu / g, and the dosage is 0.5% of the mass of imported feces and urine. The microbial bacterial liquid contains complex enzymes for microbial activation. The microbial activation compound enzyme is MD444, and the preparation method is as follows: ...

Embodiment 3

[0061] This embodiment processes fresh human excrement and urine in the Pinghu area, and the treatment process includes the following steps:

[0062] 1) Feces and urine are introduced into the excrement and urine circulation treatment device, and then enter the biochemical treatment tank for treatment by the excrement and urine circulation treatment device. The biochemical treatment tank is set with an effective scale for treatment. When the volume of feces and urine treated exceeds the effective scale for treatment, it will automatically overflow to the feces. The urine circulation treatment device performs circulation treatment.

[0063] The process of aerobic biological treatment in the biochemical treatment pool is as follows: place a 3 The biochemical treatment tank filled with polyurethane sponge is regularly added with bacteria liquid containing Lactobacillus QV1 and compound enzyme MD444, and micro-nano aeration treatment is carried out at the same time. The volume of ...

Abstract

The invention discloses a mixed treatment process of feces and urine, and belongs to the field of feces and urine treatment. The treatment process comprises the following steps: 1) introducing feces and urine into a biochemical treatment tank for aerobic biological treatment, periodically adding a microbial bacterial liquid to the biochemical treatment tank, and simultaneously performing micro-nano aeration treatment; 2) introducing the treated water body in the step 1) into a sedimentation tank for solid-liquid separation; and 3) introducing the obtained supernatant liquid after treatment inthe step 2) into a deep treatment tank, introducing a small amount of ozone to generate a large amount of hydroxyl radicals by using a micro-nano aeration apparatus in the deep treatment tank, performing high-efficiency oxidation, and simultaneously performing micro-nano aeration treatment on the water body. The microbial bacterial liquid added in the step 1) comprises lactobacillus QV1, lactobacillus QV1 is deposited in the General Microbiology Center of the China Microbial Culture Collection Management Committee, and the preservation number is CGMCC No.16350. The treatment process has high treatment efficiency, and the discharge can meet the standard after two weeks of treatment.

Description

technical field [0001] The invention belongs to the field of excrement and urine treatment, and more specifically relates to a mixed treatment process of excrement and urine. Background technique [0002] At present, the mixed treatment of feces and urine mainly uses the metabolism and physical and chemical effects of microorganisms to complete the degradation of feces and urine pollutants, making the feces harmless and then returning to the environment. The main principle of microbial strains decomposing feces is to use their growth and reproduction activities to biodegrade the available macromolecular organic compounds in feces and convert them into bacterial biomass, competitively inhibit and kill pathogenic microorganisms in feces, adsorption, Degrade and transform the odorous substances produced in feces. After microbial biochemical treatment, the concentration of organic matter, ammonia nitrogen and other components in feces and urine has been significantly reduced. Ho...
