The present application relates to sewage treatment technical field, specifically to a kind of acrylonitrile sewage treatment device, comprising: microbial purification tank, exhaust mechanism, the exhaust mechanism has two and symmetrically set in the two sides of the inner wall of microbial purification tank width direction, the exhaust mechanism includes the cavity plate fixedly connected in the inner wall of microbial purification tank. By cavity plate, partition block and air separation assembly in exhaust mechanism, air can be injected and extracted into microbial purification tank, so as to provide corresponding purification environment for aerobic microorganism or anaerobic microorganism to purify sewage, and then realize that when injecting air, air exposure area and immersion area can inject air into microbial purification tank simultaneously to provide sufficient oxygen for aerobic microorganism to purify sewage, help its efficient decomposition of pollutants in sewage, while when extracting air, air separation assembly disconnects the communication of air exposure area and immersion area, so that suction airflow is only discharged from air exposure area, avoid sewage from flowing out with cavity plate, while avoiding suction airflow from immersion area to interfere with anaerobic environment in tank.

This utility model relates to a curling comb with airflow and plasma, comprising a handle and a combing head assembly. A fan is installed inside the handle. The combing head assembly includes an outer tube, an inner tube, a front cover plate, and a rear cover plate. The outer tube is connected to the front and rear cover plates at both ends, and has several air outlets. The inner tube is fixedly disposed between the front and rear cover plates within the outer tube, forming an airflow channel communicating with the air outlets. The rear cover plate is fixedly connected to the front end of the handle and has several ventilation openings connecting the airflow channel to the inner cavity of the handle. Several comb teeth on the inner tube extend through the air outlets. This curling comb with airflow and plasma can more comprehensively cover the hair stuck between the comb teeth, achieving better hair drying results during combing.

The invention provides a method for allele matching of donor mesenchymal stem cells and a receptor. The method comprises the following steps: S10, separating mesenchymal stem cells from perinatal tissue of a donor; s20, extracting genome DNA (deoxyribonucleic acid) of the mesenchymal stem cells, and performing HLA (human leukocyte antigen) genetic typing; s30, performing HLA (human leukocyte antigen) genetic typing on the DNA of the receptor; s40, performing allele spectrum comparison on the HLA gene of the receptor and the HLA gene of the mesenchymal stem cell, and calculating the matching degree; s50, judging the matching degree of the receptor and the mesenchymal stem cells according to the matching degree; and S60, storing the HLA genotyping result of the mesenchymal stem cells and the matching degree in a database, and establishing a matching library for matching the donor mesenchymal stem cells and the receptor. According to the method, a set of standardized system is established, compatibility evaluation of a donor and a receptor at the allele level is achieved, the immunological rejection risk caused by HLA mismatching is effectively predicted and avoided before treatment, and the in-vivo survival and implantation efficiency of MSCs is improved.

The invention relates to the technical field of textile ink-jet digital printing, and discloses a high-color-fastness ink-jet digital printing process which comprises the following steps: S1, fiber surface activation pretreatment: putting a fabric to be printed into plasma treatment equipment for surface activation, then soaking the fabric in a composite pretreatment solution for 20-40 minutes, rolling the fabric by a roller until the liquid rate is 65-85%, and drying the fabric by a drying oven; finally, pre-drying at 70 to 90 DEG C for 8 to 18 minutes; and S2, ink-jet printing: digital ink-jet printing equipment is adopted. According to the high-color-fastness ink-jet digital printing process, double means of plasma activation and composite pretreatment are adopted, fiber surface active sites with sufficient quantity and high stability are constructed, and the modified ink and ammonia gas are matched for synergistic color fixation, so that efficient covalent bond combination of dye and fiber is realized, and the color fastness is improved from the source. Through detection, the washing color fastness of the prepared printed fabric can reach 4.5-5 grades, the dry rubbing color fastness is larger than or equal to 4.5 grades, the wet rubbing color fastness is larger than or equal to 4 grades, and the printed fabric is far superior to existing process products.
