The utility model relates to potassium hydrogen sulfate composite powder processing technical field, concretely relates to a kind of potassium hydrogen sulfate composite powder premixing mechanism, including support seat, the potassium hydrogen sulfate composite powder premixing mechanism further includes: cradle is rotationally arranged on the support seat, mixing tank is rotationally arranged in the cradle, the drive part for driving mixing tank autorotation, several helical blades are fixed in the mixing tank inside circumferentially uniformly, and the mixing area is formed by surrounding between adjacent two helical blades.The utility model can autorotate mixing tank under the driving of drive part after raw material is filled and tightened can cover, and cradle is reciprocatingly deflected along mixing tank axial under the driving of reciprocating driving element, so that raw material flows, rolls mixing in mixing tank, greatly weaken the collision, vibration degree in mixing process of raw material, improve mixing effect.

The utility model relates to powder drying technical field, concretely relates to a kind of agitating mechanism for potassium hydrogen peroxodisulfate drying machine, including the stirring tank being located in the inside of drying machine, the stirring rod being located in the top of drying machine is driven by motor, the lower end of stirring rod is equipped with the helical blade that is inserted into the stirring tank, the top of stirring tank is open structure, the bottom of stirring tank is obliquely arranged, agitating mechanism further includes: the rack being located in the inside of drying machine;Lifting inclined plate being located in the lower end of stirring tank, lifting inclined plate is slidably arranged on the rack by guide rod, when using, by stirring rod drive helical blade rotation to continuously agitate potassium hydrogen peroxodisulfate material, simultaneously by drive portion drive lifting inclined plate continuously rotate, and reciprocating lifting action is carried out on the rack along guide rod, so as to realize that helical blade can agitate potassium hydrogen peroxodisulfate material in stirring tank in different positions, under the joint action of agitation and overturning crushing, guarantee consistency of drying.

This invention discloses a method for predicting the dosage of potassium persulfate compound salt in the factory farming of Litopenaeus vannamei, belonging to the field of intelligent disinfection control in aquaculture. The method includes: acquiring the biomechanical parameters of potassium persulfate compound salt's inactivation of pathogenic Vibrio, reactive oxygen species attenuation parameters, Vibrio growth kinetic parameters, and shrimp safety threshold; constructing a microbial growth sub-model, a disinfectant inactivation sub-model, and a disinfectant concentration attenuation sub-model, respectively; and dynamically coupling these three sub-models into a dosage prediction model in system dynamics software. Real-time physicochemical parameters of the aquaculture water are input into the model, and the initial dosage concentration of potassium persulfate compound salt, effective sterilization duration, pathogen regrowth warning, and dosing interval are dynamically output. This invention can dynamically and accurately predict the disinfectant dosage based on the water quality parameters at the aquaculture site, achieving efficient Vibrio control while ensuring shrimp safety, and is suitable for intelligent disinfection management in factory shrimp farming.

This invention belongs to the field of wastewater treatment technology, specifically a method for treating medical wastewater by synergistically removing new pollutants and pathogenic microorganisms. The method includes the following steps: S1, Pretreatment: Inorganic flocculants are added to the medical wastewater to promote the aggregation and sedimentation of suspended particles and colloids; S2, Oxidation Treatment: A composite agent is added to the pretreated medical wastewater while a direct current electric field is applied. The composite agent includes potassium persulfate, aminosulfonic acid, sodium chloride, sodium bromide, surfactant, pH buffer, composite corrosion inhibitor, anti-caking agent, and anhydrous sodium sulfate. After dissolving, the composite agent generates a strong oxidizing component that mineralizes and decomposes organic matter while killing pathogens; S3, Biochemical Treatment: The oxidized medical wastewater is then subjected to biochemical treatment to remove ammonia nitrogen and small molecule organic matter. This invention can effectively decompose various new pollutants and inactivate pathogenic microorganisms, thus improving the treatment effect.
