Abstract: The present invention relates to a method for starting a high-salinity wastewater pure-film MBBR with intertidal zone sediment as an inoculation system. The method comprises: a step of inoculating the intertidal zone sediment in a high-salinity wastewater pure-film MBBR, a filler film-culturing step, and a biofilm acclimation step. By means of the method, the inoculation of the intertidal zone sediment can accelerate the attachment to and film-formation of microorganisms on the interior of the bio-filler, shorten the film-culturing period of the MBBR process, promote the structural optimization of the biofilm flora, improve the overall salt tolerance level of the system and expand the application range of the MBBR process in high-salinity wastewater. In the present invention, intertidal zone sediment is inoculated, such that the rapid starting of the MBBR system can be achieved directly under conditions where the salinity is 1-4%, and efficient and stable operation of the system is maintained, thus effectively avoiding the problems of serious biomass loss, large outlet water quality fluctuations, etc., during the inoculation process of traditional activated sludge.

Le compteur d'horloge comprend un module de division de fréquence d'horloge, une pluralité de modules de comptage et un module d'accumulation, le module de division de fréquence d'horloge étant utilisé pour recevoir un signal d'horloge et étant configuré pour effectuer une division de fréquence sur le signal d'horloge, de façon à sortir une pluralité de signaux d'horloge divisés en fréquence, et la somme du nombre d'impulsions de la pluralité de signaux d'horloge divisés en fréquence étant égale au nombre d'impulsions du signal d'horloge ; la pluralité de modules de comptage est connectée au module de division de fréquence d'horloge et chaque module de comptage est configuré pour compter les impulsions de chaque signal d'horloge divisé en fréquence et générer une valeur de comptage initiale ; et le module d'accumulation est connecté à la pluralité de modules de comptage et est configuré pour accumuler les valeurs de comptage initiales de la pluralité de modules de comptage pour générer une valeur de comptage cible. Au moyen des modes de réalisation de la présente divulgation, le retard de fonctionnement de report d'un compteur d'horloge haute fréquence peut être efficacement réduit et une situation dans laquelle une erreur de comptage est provoquée par le retard de fonctionnement de report du compteur dépassant une période d'horloge de comptage est évitée, ce qui permet d'améliorer la fréquence de fonctionnement du compteur d'horloge.

Abstract: A halogen-free flame retardant composition and an application thereof in flame retardancy of glass fiber reinforced engineering plastics. The composition of the halogen-free flame retardant composition comprises, in mass percent: 1%-99% of a phosphorus-containing aluminum salt complex based on aluminum methyl butyl phosphinate, 1%-99% of aluminum phosphite and/or a derivative thereof, 0-80% of aluminum diethylphosphinate, 0-40% of a nitrogen-containing compound, and 0-20% of a zinc salt thermally-stable compound. The halogen-free flame retardant composition is applied to flame retardancy of glass fiber reinforced engineering plastics, and has a low molding shrinkage characteristic; and a halogen-free flame retardant glass fiber reinforced engineering plastic prepared by using the halogen-free flame retardant composition can meet the UL94V-0 flame retardant standard.

Abstract: The present disclosure relates to the field of lithium-ion batteries, and specifically relates to a high temperature resistant adhesive for a ceramic diaphragm of a lithium battery and to a preparation method therefor. The present disclosure further relates to a lithium battery diaphragm comprising the high temperature resistant adhesive. The adhesive is a latex acrylic polymer resin having an interpenetrating network structure, and the adhesive polymer has a glass transition temperature greater than 160°C; the ratio of the thermal shrinkage rate of the lithium battery diaphragm prepared from the high temperature resistant adhesive at 150°C, relative to the heat shrinkage measured at 120°C, is less than 2; there is a relatively small change in the thermal shrinkage rate of the diaphragm even with a steep increase in temperature, thus satisfying requirements for manufacturing a ceramic diaphragm having high safety performance; moreover, the present adhesive is a water-based adhesive, does not contain an organic solvent, and is safe and environmentally friendly.
