The invention provides a penaeus monodon industrialized high-density cultivating technology, comprising a young shrimp coarse standard pond, an intermediate cultivating pond, an adult shrimp cultivating pond, a rotary-drum microstrainer, an air-sifter type protein separator, a positive-negative biological processor, a purifying device, a sedimentation tank, an algae biological processor and a controller. According to the penaeus monodon industrialized high-density cultivating technology, the problems that the prawn survival rate is low, the benefit and yield are not prominent, the occupied area is overlarge, and the environmental pollution is severe are fundamentally solved through cultivating penaeus monodon by utilization of industrialized circulating water; by employment of grading multistage cultivation, the aquaculture water space can be sufficiently utilized, the water quality is guaranteed, the possibility of disease occurrence is reduced, the cultivating success rate is improved, drugs are prevented from being used, and the food safety is guaranteed; organic carbon is added in the aquaculture water through a biological floccules device so as to adjust the proportion of carbon to nitrogen, and sufficient oxygenation is combined at the same time, so that the growth of heterotrophic bacteria in the water can be promoted, ammonia nitrogen and nitrite nitrogen are reduced up to 98-100%, the feed quantity required for cultivating creatures is reduced, and the benefit is increased.
