An integrated multi-trophic aquaculture system (multico) for a primary species, preferably a carnivorous marine species with high market value, secondary, preferably an omnivorous species of medium market value and tertiary species, preferably a detrivorous species with high market value, combined with an unfolding system for the primary species to an open semi-intensive or extensive system, the multico system for the primary species is an intensive closed or semi-closed system. The secondary species is stocked in an intensive closed or semi-closed system, while the tertiary species is stocked in a semi-intensive or closed extensive or semi-closed system. The multico system of the primary species is in communication with the system of the secondary species, while the system of the secondary species is in communication with the system of the tertiary species.

The invention discloses a method for applying pre-ozonation and aerated biological activated carbon processes to feedwater treatment. The method combines ozone pre-oxidation, an aerated biological activated carbon filter tank and a coagulation-sedimentation-sand filtering-disinfection conventional feedwater treatment process to produce drinking water, is a feedwater treatment process for improving water quality of feed water aiming at micro-polluted drinking water sources, and integrates the characteristics of an aerated biofilter biological pre-treatment process and an ozone biological activated carbon advanced water-purifying process. Raw water enters a pre-ozonation contact tank, a coagulation sedimentation tank and the aerated biological activated carbon filter tank orderly, is disinfected, enters a sand filtering tank, and finally flows into a clear water tank. Because the pre-ozonation contact tank and the aerated biological activated carbon filter tank are arranged in the conventional feedwater treatment process, the effect of removing organic matters, ammonia nitrogen, pathogenic microorganism, odor, chroma and the like is greatly improved, and the water quality safety of the method is obviously superior to that of the biological pre-treatment process and the ozone biological activated carbon advanced water-purifying process.

The invention discloses a standardization system for multilingual medical terminology based on deep adversarial learning, including a standard medical terminology database, a file preprocessing module, a candidate term set generation module, and a candidate term set rearrangement module; the file preprocessing module is used to unify The format of the medical term string in the real world, and the long string is divided into individual Chinese and English word tokens; the candidate term set generation module is used to filter out the first n medical terms that are consistent with the real world medical term from the standard medical term set The most similar candidate standard term; the candidate term set rearrangement module: used to form a term pair between the real-world medical term and the screened candidate term, and mark it as a positive example and a negative example according to the degree of matching, as the input of the deep learning model, The model is iteratively optimized to generate an automatic term matching model.
