Embodiment 1
[0016] Embodiment 1, the compound self-circulation culture method of fruits and vegetables and aquatic ecological water is carried out according to the following steps: the first step, the ecological water after feeding in the aquaculture pond is absorbed and decomposed by fish, shrimp and crab to obtain a cycle A part of the primary circulating liquid is returned to the aquaculture pond after disinfection, microbial water purification treatment and oxygen melting in sequence. The remaining part of the primary circulating liquid is electrodialyzed to obtain a primary clear liquid and a primary suspension nutrient solution. Flow to the aquaculture pond; in the second step, the primary suspended nutrient solution is confluent and filled into the ecological water in the hydroponic tube, and pumped from the head into the hydroponic tube connected from top to bottom through the U-shaped elbow. The roots of fruits and vegetables cultivated on the cultivation hole are absorbed to obta...
Embodiment 2
[0017] Embodiment 2, as the optimization of the above-mentioned embodiment, in the first step, 1 / 2 to 9 / 10 of the total flow rate of the primary circulating liquid is returned to the aquaculture pond after being sterilized, microbial water purification treatment and oxygen melting in turn, and the primary circulating liquid The remaining part of the electrodialysis is used to obtain the primary clear liquid and the primary suspension nutrient solution, and the primary clear liquid is returned to the aquaculture pond; or / and, in the second step, 1 / 2 to 9 / of the total flow of the secondary circulating liquid 10 Return the water from the head of the hydroponic tube to the hydroponic tube, and the remaining part of the secondary circulating liquid is electrodialyzed to obtain a secondary clear liquid and a secondary suspended nutrient solution.
Embodiment 3
[0018] Embodiment 3, as the optimization of the above-mentioned embodiment, in the first step, the disinfection treatment adopts ultraviolet disinfection treatment; or / and, the microbial water purification treatment adds 5g to 10g of nitrifying bacteria to each side of the circulating liquid, and performs the microbial water purification treatment ; Or / and, the oxygen content of the primary circulating fluid after melting oxygen is 6mg / L to 10mg / L; each side is 1M 3 .
