The invention discloses a method for repairing soils polluted by heavy metal Cd, characterized in that a plant used for repairing the metal Cd is Cd-tolerant tobacco K326, a used soil chelation inducer is a hydrochloric acid solution of chitosan, microbes used for activating the heavy metal Cd in the soils are bacterial strain obtained by gathering, screening and separation in a laboratory, the three substances are combined to repair the soils polluted by the heavy metal Cd. The method comprises the following steps: cultivating a K326 seedling to the 3-leaf one-heart stage, then transplanting; before transplanting, adding chitosan; before transplanting, carrying out mass fermental cultivation of separated, screened and purified bacterial strain, adding the active bacterial strain of the heavy metal Cd at the logarithmic phase in the soils, and stirring for the subsequent use; and after transplanting the tobacco plant, regularly carrying out management. According to the invention, a plant-microorganism united repair method is adopted, and a certain amount of microbes of the active heavy metal are added in the soils to effect together, thus the repair efficiency is raised, and the efficiency of repairing the soils polluted by the heavy metal Cd is raised.

The invention discloses a method for realizing shortcut nitration of high ammonia nitrogen wastewater. The method comprises the following steps of: culturing nitrosation dominant flora; and performing ammonia sewage treatment by using the flora as an inoculum, namely adding the cultured nitrosation dominant flora into an aeration reactor to treat the ammonia wastewater, wherein the adding amount of the cultured nitrosation dominant flora accords with a condition that: sludge concentration is 800-2,000mg / L after the cultured nitrosation dominant flora is added; and the treatment conditions arethat: the temperature is 18-40DEG C, the dissolved oxygen is 0.1-3mg / L, and the pH is 7- 9. The unique nitrosation dominant flora culture method is adopted, stable and high-efficiency ammonia nitrogen wastewater treatment effect can be achieved, and the problem of instability of the shortcut nitration in actual application is solved.

The invention discloses a method for preparing a probiotic brown lactobacillus beverage product with large amount of bacteria, which comprises the steps of Maillard reaction, probiotic fermentation and post treatment, wherein the probiotic fermentation step comprises: hydrating and sterilizing defatted milk powder or defatted fresh milk, reacting the defatted milk powder or the defatted fresh milk for 2.5 hours at the temperature of between 95 and 98 DEG C till the milky yellow becomes brown at the end point of the reaction, cooling the reaction product to between 37 and 38 DEG C, inoculating the reaction product to a Lactobacillus casei strain, statically fermenting the strain for 48 to 72 hours at the temperature of between 37 and 38 DEG C till the pH reaches 3.8 to 4.0, and cooling the fermentation product to between 2 and 6 DEG C; and the post treatment steps comprises: preparing base solution by using sugar, high fructose corn syrup, pectin and purified water, wherein the weight ratio of the base solution to the probiotic fermentation solution is 1 to 3; and the pH is adjusted to between 3.5 and 3.6; homogenizing the base solution, cooling the base solution to between 2 and 6 DEG C, canning products after passing detection, maturing the products for 4 to 8 hours at the temperature of between 2 and 6 DEG C, and delivery the products from a storage. The number of the living bacteria in the shelf life of the product can reach 1*108 to 1*1,010cfu / ml; and the product has zero fat and super clear mouthfeel, has no viscosity, has high probiotic detection rate, and can effectively keep or recover the intestinal microbial balance.

The invention discloses a dynamic avoidance method for multiple robots in collaborative operation. The method comprises the steps: carrying out the path pre-planning of all tasks in a task pool according to the priorities, and reducing the conflict intervention between robots from a planning layer; monitoring the current operation states of all the robots, dynamically pre-judging the safety distance, generating different types of stop points, coordinating the operation of the robots, and solving the technical problems of collision, delay, interlocking and the like during the cooperative operation of the robots. Overall scheduling is carried out to optimize resource distribution, traffic control and coordinated avoidance are achieved, local peer-to-peer communication solves the overall operation problem after the robot individual is abnormal, and therefore the robustness of the whole scheduling system is guaranteed. The method is suitable for multi-robot scheduling avoidance scenes suchas factory automation and storage commodity transfer.

The invention discloses a method for culturing granular sludge by shortcut denitrification. The method comprises the following steps of putting inoculated sludge into an aerobic reactor, and performing enrichment culture on denitrifying sludge by using high ammonia-nitrogen low COD wastewater; then, performing secondary enrichment screening by wastewater simultaneously containing nitrate nitrogen, nitrite and COD in a facultative anaeration reactor, and performing third enrichment screening by wastewater only containing nitrite and COD; and finally acclimating by wastewater simultaneously containing ammonia-nitrogen, nitrite and COD to obtain the denitrified granular sludge with high removal rate on the nitrite when various forms of nitrogen coexist commonly. By the method, the denitrified granular sludge which can survive in a complicated environment and is capable of effectively treating wastewater nitrous nitrogen under proper condition can be obtained, and the shortcut nitrification-denitrification process can be truly applied to actual engineering conveniently.

A process for producing biological diesel oil by fixed enzyme method is carried out by taking sodium alginate, kaoline, glutaraldehyde, gelatin and lactose as co-fixer, fixing the lipase, piling the spherical fixed enzyme in filled bed columnar reactor naturally, alcoholyzing animal and plant oil fatty with biological diesel oil as solvent and producing biological diesel oil. It is cheap, has less consumption and by product and better quality. It can be used for continuous production.
