[0017] Example 1 Construction of zero-discharge fish and shrimp polyculture system
[0018] (1) The zero-emission fish and shrimp polyculture system can be built into a semi-underground or above-ground structure.
[0019] (2) The fish and shrimp polyculture tank (21) and the multifunctional sedimentation tank (22) are connected through a connecting pipe (23). One end of the connecting pipe (23) is connected to the mud collecting pipe (2), and the other end is connected to the water inlet pipe (13 ), the sediment in the mud collecting pipe (2) flows to the water inlet pipe (13) by the water pressure difference, the solenoid valve (8) is installed on the connecting pipe (23), and the solenoid valve (8) is regulated by the PLC control system Opening and closing frequency.
[0020] (3) The fish and shrimp polyculture pond (21) has a length of 10-15 meters, a width of 2.0-4.0 meters, and a depth of 2.0 meters. The bottom is a jagged mud collection well (7), and the mud collection ...
