Abstract: Provided are a carbazole-based bis-chalcone, a preparation method and use thereof. The carbazole-based bis-chalcone has a chemical structural formula of Formula I, where in the Formula I, R is selected from the group consisting of —H, —SMe, —OMe, NMe2, NEt2, CF3, and —N(Ph)2.

Abstract: A treatment agent for water quenching and slag flushing of a yellow phosphorus slag using reverse osmosis concentrate (ROC) and a preparation method thereof are provided. The treatment agent for water quenching and slag flushing of the yellow phosphorus slag using ROC includes the following components in mass percentage: 3% to 10% of a dispersant, 1% to 3% of a wetting agent, 3% to 10% of a scale inhibitor, 3% to 8% of a carbon steel corrosion inhibitor, 0.5% to 1% of a copper corrosion inhibitor, 5% to 25% of a complex cleaning agent, and water as a balance.

Abstract: The present disclosure relates to an automatic control system and method for water treatment of a thermal sterilization kettle. The system comprises a sampling module, a monitoring module and a control module, wherein the sampling module is used for respectively sampling hot water and cold water, and the monitoring module is arranged to respectively monitor online fluorescence signals in the sampled hot water and the sampled cold water; the control module is used for respectively controlling whether to add a compound medicament into a hot water area or not according to the online fluorescence signal of the sampled hot water and controlling whether to add the compound medicament into a cold water area or not according to the online fluorescence signal of the sampled cold water; and meanwhile, the monitoring module is further used for monitoring the residual chlorine signal of the sampled cold water.
