The invention discloses a double-fishpond circulating water ecological culture
system. The
system comprises a
natural environment area, a convergence area, a central
sewage discharge area, a
precipitation filtration area, a comprehensive air floatation area and an original ecological regulation area, and is characterized in that the convergence area is arranged on the inner side of the
natural environment area, the central
sewage discharge area is arranged in the middle of the convergence area, an overflow
pipe is arranged at the center of the central
sewage discharge area, the bottom end of the overflow
pipe is connected with a drainage
pipe, a
sewage discharge pipe is laid at the bottom end of the central
sewage discharge area, the drainage pipe is connected to the
precipitation filtration area through a water pump, the
sewage discharge pipe is connected to the
precipitation filtration area through a sewage suction pump, and the precipitation filtration area is connected to the comprehensive air floatation area through a pipe. Culture water is purified more thoroughly, purification pressure of a
water diversion area is reduced, so that
water quality of the whole circulating waterbody is more stable,
organic matter in ponds can be timely removed, the problems of
oxygen consumption and release of toxic substances during
organic matter degradation are solved, and the
culture environment is better.
