Lobster breeding tail water ecological purification system and operation method

The invention discloses a lobster breeding tail water ecological purification system and an operation method. The system comprises an irrigation and drainage system (1), a water level adjusting system (2), a water quality monitoring system (3), a lobster breeding system (4) and a rice field planting system (5). The irrigation and drainage system (1) conveys a water source to the lobster breeding system (4), the water quality monitoring system (3) detects the water quality of breeding units, the water level adjusting system (2) adjusts the water level and dispatches the water quantity according to the pollutant threshold value of each breeding unit, if the pollutant concentration exceeds the standard, t water enters the rice field planting system (5) for tail water ecological treatment, and finally aquaculture water circulation is achieved. According to the lobster breeding tail water ecological purification system, a shrimp-rice-fish three-in-one ecological breeding purification system is constructed, a water
