Further, an acid-base detector is arranged in the third purifying tank; one side of the third purifying tank is provided with a container for containing quicklime powder.

Because the crayfish prefers a weakly alkaline water environment, the acid-base detector is arranged, when the measured PH value is lower than the measured PH value, quicklime powder is scooped into the third water purification tank from the container until the reading on the acid-base detector is slightly larger, so that the water source meets the requirement of weakly alkaline, and the crayfish growth is more suitable.

Furthermore, baffles higher than the water depth are vertically inserted among the plurality of breeding rice fields and connected with the bank close to one side of the water pump. Through setting up the baffle, restricted the circulation direction of rivers, ensured that the rivers must flow to the farthest end in breed district, avoided being close to the water source exchange of water pump one side frequently, and the water source exchange slow condition of keeping away from water pump one side appears, has promoted the efficiency of whole breed district's water source exchange.

The beneficial effects of the utility model are that:

1. the three-stage purification tank is arranged, and operations such as magazine taking out, oxygen content increasing, alkalescence adjusting and the like are performed on a water source respectively, so that the water source conveyed back to the culture area has the characteristics of cleanness, alkalescence and high oxygen content, and is more suitable for the growth of crayfishes.

2. Through setting up the baffle, limited the water source circulation route in the breed district, let the water environment of keeping away from water pump one side in the breed district also can constantly supply the water source after purifying, avoided the ecological unbalanced condition of water source in the whole breed area.
