The invention discloses a modernized intensive zero-emission intelligent pig raising system. The modernized intensive zero-emission intelligent pig raising system comprises multiple layers of pigsty unit bodies, wherein each pigsty unit body comprises a water feeding mechanism, a feed feeding line, a material tower, dung leaking plates, a waste fermenting area, a comprehensive temperature and humidity detection probe, an automatic temperature and humidity adjusting mechanism, an intaking, exhausting, ventilating and purifying mechanism and a waste stirring mechanism, wherein the tail ends of the water feeding mechanism and the feed feeding line stretch into the material tower; the waste stirring mechanism is arranged above the waste fermenting area. Water and feed automatically enter a material mixing tank, and temperature and humidity are automatically detected and supplied, so that manual operation is basically not needed, and thus the operating efficiency is high, the labor intensity is low, and the labor cost is reduced; wastes automatically drop off and are fermented into an organic fertilizer for secondary use, so that the fermenting decomposition efficiency is high and environmental soil and the like is not affected; vertical ventilation is more smooth and free of a dead corner, so that steam heat and harmful gas generated during fermentation are emitted more thoroughly and the normal growth and the slaughtering cycle of pigs are not affected; therefore, the system is more modern and intelligent and more convenient in operation.
