In addition to this, wastewater disposal basin 3 needs user to configure wastewater treatment equipment, can directly purchase existing wastewater treatment
Device, such as: the wastewater treatment equipment of the model CXWSZ of the poly- Machinery Co., Ltd.'s production of radically reforming in Zhucheng；Water inlet pipe 8 and outer
The connection of water receiving source, can need to be selected according to user with artificial recharge also mechanic water injection, fill the water according to mechanical system, this
Field personnel may be implemented completely, not be related to improving, details are not described herein.
It should be noted that cray fattening period needs to filter the nutrition such as planktonic algae, wheel animalcule, organic debris in drinking water
Body, while seedling can also absorb the middle-size and small-size planktonic organism of breeding water body, therefore the planktonic algae that the fattening period of cray needs
It is placed in floating frame 211, organic debris and the small-sized insects that swim need user to be manually placed into culture pond；Culture pond 23
Quantity be adjusted according to specific circumstances, oxygen supplying tube 16 of going bail for, the first sub-feed tube 12 and the second sub-feed tube 13 can arrive conveying
Into each culture pond 23, it is ensured that other partitions other than first partition 220 are intended to the structure with second partition 221
It is identical.
It is worth supplement, the increasing for the model YX-41D-1 that oxygen increasing pump 15 is produced using Shanghai full blast Industrial Co., Ltd.
Oxygen machine, self priming pump of the water pump 17 using the model 100ZX100-20 of Shanghai Run Ji mechanical equipment Co., Ltd production, stirring electricity
Machine 5 is using the motor of the model YL of Chen Xi Import and Export Co., Ltd., Wenling city production, and matched driving power is by respective
Producer provides；In addition, being related to aerator, water pump and motor in the present invention is the prior art, those skilled in the art are complete
It may be implemented, be not necessarily to superfluous words, the content that the present invention protects is not related to structure and working principle to aerator, water pump and motor yet
It improves.
When in use with biological breeding apparatus, user is by oxygen increasing pump 15 for the freshwater crayfish cultivation fattening period of the present embodiment
External power supply is connected with stirring motor 5 makes its work, and oxygen can be delivered in each culture pond 23 in oxygen supplying tube 16, then make
The raw material that rich water makes is poured into agitator tank 40 by user from feed pipe 7, then injects water source, water and raw material from water inlet pipe 8
It is thoroughly mixed under the action of stirring motor 5 and propeller 10, after waiting rich water stirring parts 4 to complete work, user point
The flow control valve 14 on the first sub-feed tube 12 and the second sub-feed tube 13 is not opened, rich water is in the first sub-feed tube 12 and second point
The tapping of expects pipe 13 enters the bottom space of culture pond 23 from filter ring 20, can control rich water by flow control valve 14
Culture pond 23 slowly is entered, ensure that rich water nutriment always exists in culture pond 23, avoids cray and lacks nutriment
Occur, during fattening, the planktonic algae user that cray needs needs to be placed into the floating frame in each culture pond 23
In 211, other nutriment need user to be placed directly into each culture pond 23；After the fattening period of cray, user
Water pump 17 is opened, because of the effect of the first gauze screen 224, the bottom of each culture pond 23 is connection, in the effect of water pump 17
Under, drinking-water pipe 18 extracts water out of hithermost culture pond 23, then enters in wastewater disposal basin 3 from drainpipe 19.
