preparation example Construction

[0151] The preparation of microbial litter of the present invention comprises the steps:

[0152] (a) Bacteria preparation:

[0153] In the present invention, the combined use of Bacillus licheniformis, Bacillus subtilis, Pediococcus pentosaceae, and Trichoderma longifolia is mainly used to realize the biochemical decomposition and reuse of human excrement and solid organic waste; and The above four strains are beneficial bacteria.

[0154] Among them, Bacillus licheniformis and Bacillus subtilis were respectively inoculated in the culture medium for the bacteria, and then fermented and multiplied in the fermenter; then, the strains were placed in the tank when they were most vigorous (the number of multiplied bacteria > 20 billion / ml) , and adding a dry adsorbent for adsorption, drying at normal temperature (preferably 20-28° C.), and pulverizing into powder; respectively obtaining Bacillus licheniformis powder and Bacillus subtilis powder.

[0155] Pediococcus pentosacea b...

Embodiment 1

[0235] This embodiment provides a kind of microbial litter toilet system, wherein the microbial litter is prepared by the following method:

[0236] (1) Preparation of microbial agents:

[0237] (i) Mix 60-80 mesh wheat bran / rice husk powder with 100-120 mesh medical stone / sepiolite at a mass ratio of 7:3 to obtain a dry adsorbent.

[0238] (ii) Inoculate Bacillus licheniformis and Bacillus subtilis in the culture medium for bacteria respectively, and then carry out fermentation and multiplication in the fermenter; then, put the strains in the tank when they are most vigorous (the number of multiplication bacteria > 20 billion / ml), add a dry adsorbent for adsorption, dry at room temperature, and pulverize into powder to obtain Bacillus licheniformis powder and Bacillus subtilis powder respectively;

[0239] Pediococcus pentosacea was inserted into the MRS medium, and then multiplied in the fermenter. The optimum growth temperature of the fermenter was controlled at 35°C, and...

experiment example 1

[0249] The microbial bedding material that embodiment is made is filled in volume respectively and be 3m 3 , and in a litter tank with the same shape, and then the resulting litter tank is connected with a flap squatting device to obtain the microbial litter toilet system of Example 1, and then randomly conduct experimental tests in a certain place in the north, and the experimental tests are carried out in autumn , carried out in families with similar population composition and age; at the same time, the common dry toilet without microbial bedding was used as a comparison; the results are shown in the following table:

[0250] project Temperature / ℃ Humidity / % Airflow / (m / s) Illumination / lx Ammonia concentration in air / 1×10-6 Concentration of hydrogen sulfide in air / 1×10-6 Concentration of microorganisms in the air (million units / m3) Concentration of carbon dioxide in the air / 1×10-6 Noise / dB Particles / (mg / m3) Suitable range 15-25 50-80...

Abstract

The invention provides a microbial bedding toilet system, which relates to the technical field of biology and sanitary ware. The microbial bedding toilet system provided by the invention includes a toilet, a bedding device and a microbial bedding located inside the bedding device. Biochemically decompose feces and urine through the microbial bedding in the bedding device, and produce small molecular simple substances that can be absorbed by crops. Moreover, the maintenance of the microbial litter toilet system is relatively simple, and it only needs to stir the litter every few days to disperse the excrement, and fully contact and mix with the litter to speed up decomposition. In addition, the above microbial litter toilet system can be further used for the decomposition of solid organic waste. After a period of use, the waste microbial bedding can be composted to achieve high-temperature maturity, and organic fertilizers for agricultural planting can be obtained to achieve effective recycling of waste bedding.

Description

technical field [0001] The invention relates to the technical field of biology and sanitary ware, in particular to a microbial litter toilet system. Background technique [0002] At present, urban public toilets and rural toilets are mostly designed to use dead pits or water to flush septic tanks, and where conditions permit, they enter the municipal sewage pipe network; There will be pipe blockage and biogas generation, prone to explosion accidents, secondary pollution and investment in sewage treatment costs, high operating costs, and waste of resources. Moreover, flushing the toilet with water magnifies the dirt by more than 6 times and transfers it. The transfer process pollutes the surrounding environment and increases the difficulty of treatment. [0003] Generally, new excrement and urine are not very smelly, but decompose in a natural environment at a slow rate. When old excrement and urine decay, they release foul odors—ammonia, hydrogen sulfide, skatole, etc. Many...
