The invention discloses a technique for preparing a mushroom nutrition pot by a biogas residue steam explosion technique. The technique comprises the following steps: mixing fresh biogas residue and manure powder in a ratio of 7:3 (with the water content of 40%), sending the mixture into a steam explosion tank, and carrying out steam explosion treatment; after the raw materials are mixed, stamping in the steam explosion tank, and keeping the pressure at 1.8 MPa for 2-3 minutes; and mixing 1% of calcium superphosphate, 1% of urea, 1% of lime powder, 1% of gypsum powder and 1% of calcium carbonate into the raw materials subjected to steam explosion, adding 1.5% of adhesive, controlling the water content at 35% or so, and finally, carrying out pressure molding. The biogas residue has rich nutrients, and thus, has close nutrient content to the edible fungus culture medium; and the biogas residue has fewer infectious microbes, and is very suitable for the growth of edible fungi after being subjected to steam explosion. By using the biogas residue for culturing the edible fungi, the mushroom nutrition pot has the advantages of wide material sources, simple technique, low cost, high quality, high yield and the like, implements high value utilization of the biogas residue, and has obvious social benefits and economic benefits.

The invention discloses a preparation method of a plant compound high-efficiency antibacterial deodorant based on HQ22 bean extract. Process into powder; mix the above two powders evenly according to a certain mass ratio, and inoculate with a certain inoculation amount of Bacillus natto seed liquid; ferment the mixture to obtain a dark brown fermented liquid; separate the fermented liquid Purify to obtain the active ingredients of high-efficiency antibacterial deodorant; mix the active ingredients with a certain proportion of surfactants, buffers, solvents, and fragrances to prepare a plant compound type based on HQ22 bean extracts High-efficiency antibacterial deodorant. The invention adopts biological antibacterial deodorization technology, uses safe and harmless HQ22 bean extracts (natto bacteria, nattokinase, soybean amino acid) and plant leaves (polyphenols) as raw materials, and finally forms The plant compound biological fungicide is used as the active ingredient, using natto bacteria and nattokinase to phagocytize and decompose odor and bacteria, and at the same time, using the interface impedance of soybean amino acids and polyphenols formed by it to achieve inhibition The role of surrounding bacteria to reproduce. The advantage of the method is that it has high-efficiency deodorization and antibacterial effects, so it has good application prospects in the fields of safety, harmlessness, environmental protection, antibacterial and deodorization.

The invention discloses a method for removing organic pollutants and synergistically killing and inhibiting bacteria by means of catalytic ozonation. According to the method, ozone is mixed with a sample to be treated, and the mixture is then introduced into a device filled with a catalyst so as to be treated. A preparation method of the catalyst comprises the following steps: (1) putting silica gel into a NaOH aqueous solution for soaking, then putting the soaked silica gel into a nitric acid aqueous solution for dipping, taking out the silica gel, washing to neutral, and then drying to obtain a modified silica gel carrier; (2) dipping the modified silica gel carrier into a metal salt solution; after dipping is completed, drying and aging by means of microwave radiation; finally, calcining to obtain the catalyst. The multi-component catalyst obtained by the preparation method has the advantages of being rapid in reaction rate, more complete in degradation of organic micro-pollutants,free from toxic and harmful by-products, low in ozone demand concentration, high in ozone utilization efficiency, and the like when being used in treatment of tap water with the organic micro-pollutants. The catalytic ozonation also can be used for sterilizing the water body when removing the organic micro-pollutants; furthermore, the method is good in sterilizing effect and rapid in speed.
