The invention relates to the field of river crab aquaculture, in particular to a self
purification system for crab pond aquaculture with air stripping and water retracing flowing
around the whole pond.
River crab is the most important freshwater crab in China. It has tender meat, with
delicious taste and rich nutrition, and it has high economic value. At present, the culture of
river crabs in ponds mainly uses aquatic plants planted in still water ponds to cultivate river
crabs (i.e., planting grass to raise crabs). This model has achieved certain success by
planting grass and changing water regularly to ensure the habitat and growth environment
of river crabs, but there are also some obvious problems: (1) During the process of changing
water, the waste water discharged causes pollution to the surrounding water bodies, and
the utilization efficiency of water resources is low. (2) Water purification makes the
dissolved oxygen in pond water body unsatisfactory, especially the disclosure of oxygen
content in water body at night. (3) Summer is the peak season of crab culture, which is the
key stage of crab growth. However, the high temperature in summer makes the water body
temperature of culture pond high, which threatens the growth and even survival of crab. (4)
There is a significant difference in the living state between the pond still water culture and the river crab in the natural living environment, which hinders the further improvement of the river crab culture quality.
The purpose of the present invention is to provide a self-purification system for crab
pond aquaculture with air stripping and water retracing flowing around the whole pond,
which can realize the cyclic utilization of water resources, self-purification of water bodies
and river crab culture in flowing water without changing water. In addition, the problems
existing in the cultivation of river crabs in still water ponds are solved, such as the slow
growth of river crabs due to poor dissolved oxygen in pond water and the poor growth
environment of river crabs due to high water temperature in summer.
The technical problem solved by the invention can be realized by adopting the
following technical scheme:
The system comprises a pond (1) which is provided with a river crab culture area (2)
and a water purification area (3).
A drainage plate (18) is arranged between the crab culture area (2) and the water
purification area (3), and water in the crab culture area (2) flows to the water purification
area (3) through the drainage plate (18).
The water purification zone (3) comprises a filter pool (11) communicated with the
river crab culture zone (2), wherein the filter pool (11) is used for removing impurities in
water flowing from the river crab culture zone (2); the outlet of the filter pool (11) is communicated with a sterilization pool (12); a sterilization lamp (14) is arranged in the sterilization pool (12) . The outlet of the sterilization pool (12) is communicated with the cooling pool (13), and the top of the cooling pool (13) is covered with a shading net (15), which is used for avoiding sunlight to reduce the temperature of water. A separation wall
(4) is arranged at the junction of the outlet end of the cooling pool (13) and the river crab
culture area (2).
A stripping device (5) is arranged at the separation wall (4), and the stripping device
(5) comprises a compressor (9), an air inlet pipe (8) and a water outlet pipe (10), wherein
the compressor (9) is installed on the separation wall (4), and a compressed gas outlet of
the compressor (9) is communicated with the air inlet pipe (8). The air inlet pipe (8) extends
to the bottom of the outlet end of the cooling pond (13) and is communicated with the water
outlet pipe (10), the diameter of which is larger than that of the air inlet pipe (8), one end
of the water outlet pipe (10) is communicated with the air inlet pipe (8), and the other end
of the water outlet pipe (10) extends to the crab culture area (2).
Further, a plurality of soft enclosures (17) are arranged in the river crab culture area
(2), and the soft enclosures (17) divide the river crab culture area (2) into folded waterways,
the starting point of which is adjacent to the cooling pool (13) of the water purification area
(3), and the ending point of which is adjacent to the filtration pool (11) of the water
purification area (3).
In addition, the self-purification system for crab pond aquaculture with air stripping
and water retracing flowing around the whole pond according to claim 1, which is
characterized in that a plurality of groups of water outlets (16) distributed up and down are arranged on the drainage plate (18), a chute is arranged on the inner wall of the water outlets
(16), and a movable baffle (19) for switching the opening/closing of the water outlets (16)
is arranged in the chute.
Furthermore, the other end of the water outlet pipe (10) is provided with an anti-reflux
plate (7), one side of which is a crab breeding area (2), the other side of which is a water
purification area (3), and the other side of which is also provided with a guide plate (6).
Further, the outlet end of the cooling pool (13) and the depth of the river crab culture
area (2) have a drop of 80-120cm.
Additional, there are some aquatic plants planted in the water body of the filtration
pool (11), as well as aquatic animals cultured in the water body of the filtration pool (11).
Beneficial effect:
It realizes water recycling and reduces the waste of water resources. The water in the
crab aquaculture area is introduced into the water purification area, and then the purified
water is pushed into the aquaculture pond by the multi-level purification process of
filtration, sterilization, and cooling, and then the purified water is retraced into the
aquaculture pond by the air lifting device. The vertical height difference between the
aquaculture tank and the purification tank is designed to push the deep water in the
purification tank into the aquaculture tank, which maintains the temperature of the
aquaculture tank and increases the amount of dissolved oxygen in the water. Crab
excrement and other impurities are collected for vegetable cultivation, and the remaining
bait can be used for aquatic animal consumption.
