This invention discloses a compound traditional Chinese medicine powder inhaler for respiratory tract infections and its preparation method, relating to the field of pharmaceutical formulation technology. The compound traditional Chinese medicine powder inhaler for respiratory tract infections is composed of polysaccharide composite gel microspheres, forsythia, scutellaria, honeysuckle, and isatis root. The polysaccharide composite gel microspheres are composed of seaweed sulfated polysaccharide, lentinan, calcium chloride, and curcumin. Seaweed sulfated polysaccharide, lentinan, curcumin, and calcium chloride cross-link to form a three-dimensional network spherical structure, improving the particle morphology and flowability of the micropowder. Furthermore, due to its good hygroscopic and moisturizing properties, it competitively reduces the moisture absorption of the micropowder, preventing aggregation and further improving flowability. In addition, the gel microspheres have excellent adhesion, adhering to the infection site after entering the respiratory tract, reducing expulsion losses due to respiration, maintaining an effective drug concentration at the infection site, and improving therapeutic efficacy.

The utility model relates to a kind of descaling devices, including mainframe box, processing pipeline is located in mainframe box and multiple groups are arranged in parallel, first closed chamber and second closed chamber are arranged at the both ends of mainframe box, the both ends of processing pipeline are communicated with first closed chamber and second closed chamber respectively, first closed chamber and second closed chamber are communicated with one end of descaling pipeline, the other end of descaling pipeline is communicated with medicament storage tank, medicament storage tank imports descaling reagent by pump, pump circulates reagent along first closed chamber, second closed chamber and processing pipeline, by high efficiency, the scale layer of these parts is removed, avoid the case that water passage flow is small, ensure the entire water system's unobstructed, maintain the purification efficiency of purification mainframe to cooling circulating water, ensure that equipment can be stably and efficiently operated, reduce the risk that equipment efficiency is reduced due to scale layer accumulation, reduce the maintenance cost and energy consumption cost of enterprise.

The present application relates to sewage treatment technical field, disclose a kind of membrane aeration biological membrane reactor's operating method and operating device, sewage treatment system.The operating method has at least one control cycle during the continuous operation of reactor, the cycle includes: pre-control step, provide negative pressure pulse to membrane assembly inside, the normal compressive stress directed to membrane silk inside is applied to the biological membrane attached to the outer surface of membrane, so that the microstrain of outer layer structure is generated;Fluidized cutting step, add and fluidize circulating cutting microparticles to reactor, and microparticles are rolled cutting to the surface of biological membrane under the driving of fluid.By the cutting action of cutting microparticle and negative pressure pulse, the outer layer of biological membrane is selectively stripped from invalid biomass.The present application realizes the fine control from inside to outside to biological membrane under the condition of not interrupting sewage treatment process, can long-term maintain biological membrane in thin, high-activity ideal mass transfer state, effectively solve the problem that mass transfer efficiency attenuates with operating time.

The invention discloses a preparation method of pH gradient active drug loading type maqui berry anthocyanin-curcumin compound lipidosome, belongs to the fields of biological medicines, food science and nutritional health-care products, and particularly relates to a nano drug delivery system and preparation of functional foods and dietary supplements. According to the method, the water-soluble maqui berry anthocyanin and the fat-soluble curcumin are efficiently entrapped at the same time by utilizing a unique double-layer structure of the lipidosome and through a film dispersion-hydration technology. Soybean lecithin and cholesterol are used as main membrane materials, tea polyphenol or vitamin E and other antioxidants are combined, and curcumin is induced to transmembrane-transfer from a lipid bilayer membrane to an internal water phase through precise pH gradient control and mild heating, so that the encapsulation efficiency of curcumin is remarkably improved. Then, through the steps of high-pressure microjet homogenization, low-temperature dialysis and the like, the maqui berry anthocyanin-curcumin compound liposome which is uniform in particle size, high in stability and excellent in encapsulation efficiency is prepared.
