The invention provides a conductivity-adjustable bird droppings simulant as well as a preparation method and application thereof. The bird droppings simulant comprises the following raw materials: 3-7% of sodium chloride, 0.5-3% of sodium bicarbonate, 8-9% of uric acid, 11-14% of flour, 0.8-2% of xanthan gum and the balance of deionized water. The conductivity of the bird droppings simulant can be regulated and controlled, so that the conductivity can be regulated in a range of 0.6-1.2 mS / cm, the conductivity of bird droppings in different environments can be simulated more accurately, the influence of different conductivity of the bird droppings on a pollution flashover mechanism can be researched, and a scientific basis is provided for anti-pollution flashover measures of a power transmission line. The bird droppings simulant provided by the invention can maintain stable conductivity under different temperature and humidity environments, and is suitable for research on bird droppings flashover of power transmission lines under different climate conditions in Inner Mongolia areas.

The present application relates to a complex probiotic preparation containing Lactobacillus acidophilus WP285 and its use in the preparation of a product for inhibiting the formation of bird stone in pets, the strain in the complex probiotic preparation is composed of Bacillus coagulans Bacillus coagulans BC66 strain and Lactobacillus acidophilus Lactobacillus acidophilus WP285 strain. The present application finds that both BC66 strain and WP285 strain have excellent effect in inhibiting the formation of bird stone in pets, and they can synergistically enhance each other, the complex probiotic preparation can effectively reduce the pH value of the simulated stone formation environment and inhibit the formation and deposition of bird stone crystals in vitro; through pet clinical test, it is confirmed that the complex probiotic preparation can effectively and continuously adjust the urine pH value of susceptible cats to the weak acidic range which is not conducive to the formation of bird stone, and significantly reduces the number of bird stone crystals in urine.

The invention relates to the field of agricultural planting, and provides a soil conditioner as well as a preparation method and application thereof. The soil conditioner is prepared from the following raw materials in parts by mass: 30 to 80 parts of guano phosphorite, 10 to 20 parts of zeolite, 10 to 20 parts of shell, 10 to 20 parts of volcanic ash, 10 to 20 parts of activated carbon, 5 to 10 parts of silicon fertilizer, 5 to 10 parts of humic acid and 10 to 20 parts of rice husk. The soil conditioner provided by the invention not only can remarkably reduce the content of heavy metals such as cadmium, lead, chromium, mercury and the like in crops, but also can effectively increase the content of selenium and strontium in the crops, meanwhile, the soil conditioner has the effects of promoting crop growth and increasing crop yield, and double improvement of soil improvement and crop quality and yield is realized.

The invention relates to a compound probiotic preparation containing lactobacillus acidophilus WP285 and application of the compound probiotic preparation in preparation of a product for inhibiting formation of pet struvite. A bacterial strain in the compound probiotic preparation is composed of a bacillus coagulans BC66 bacterial strain and a lactobacillus acidophilus WP285 bacterial strain. The invention finds that the BC66 strain and the WP285 strain both have excellent effects on inhibiting formation of pet struvite stone, and the BC66 strain and the WP285 strain can achieve synergistic interaction, and the composite probiotic preparation can effectively reduce the pH value of a simulated stone forming environment in vitro and inhibit formation and deposition of struvite crystals; clinical tests of pets prove that the composite probiotic preparation can effectively and continuously adjust the pH value of urine of a susceptible cat to a weak acid range which is not beneficial to formation of struvite, and the number of struvite crystals in the urine is remarkably reduced.

The invention provides a culture wastewater treatment method and device based on red mud-boric sludge synergistic struvite petrifaction, and the method comprises the following steps: firstly, adjusting the pH value of culture wastewater subjected to solid-liquid separation to 5.5-7.0, adding boric sludge accounting for 1-5% of the volume of the wastewater and having a particle size of less than or equal to 200 meshes, stirring for 10-60 minutes, promoting the boric sludge to release active Mg < 2 + > by using a weak acid environment, and synchronously separating out amorphous silicic acid / silica gel. Then adding a red mud-boric sludge compound, maintaining the pH value to be 8.5-9.5, and reacting for 20-60 minutes, so that NH4 < + >, PO4 < 3-> and Mg < 2 + > are combined to generate struvite; the pH of the compound agent is continuously increased to 9.0-10.0 to create an optimal crystallization window, red mud free Ca < 2 + > promotes sedimentation and forms calcium-doped struvite, and hematite induces Fe < 3 + > and PO4 < 3-> to generate FePO4 heterogeneous coprecipitation cores. The inner layer is a Fe-O-P chemical bonding layer, the middle layer forms a 50-200nm amorphous silica gel coating layer, and the outer layer establishes a Ca-O-Si bridging network, so that the nitrogen and phosphorus release period is remarkably delayed.
