Description

Marine aquaculture wastewater recycling treatment system Technical field

The invention relates to a wastewater treatment system, in particular to a marine aquaculture wastewater treatment system.

Background technique

With the improvement of marine aquaculture technology and the expansion of market demand, marine aquaculture has become an intensive, high-density, high-output farming model. At the same time, the environmental pollution caused by marine aquaculture cannot be ignored. The pollution in the environment restricts the development of the marine aquaculture industry. On the other hand, the discharge and deposition of the cultured pollutants can cause eutrophication of the water body, causing the water quality to deteriorate, which in turn leads to imbalance, disorder and even complete collapse of the aquaculture ecosystem. In the past 20 years, due to the rapid development of China's factory-based marine aquaculture industry, the discharge of coastal nursery and aquaculture wastewater has increased day by day, and the environment in the offshore waters has deteriorated severely, resulting in imbalance of ecosystems in the offshore waters, frequent red tides and disease breeding.

It can be seen that the marine aquaculture system needs to be improved, which can reduce seawater pollution and improve the quality of marine aquaculture for sustainable development.

Summary of the invention

The object of the present invention is to provide a marine aquaculture wastewater recycling and treatment system for reducing waste water discharge, reducing seawater pollution and improving culture quality.

The present invention is achieved by the following technical solutions:

A marine aquaculture wastewater recovery treatment system comprising a filtration chamber, a primary sedimentation tank, a biological filtration chamber and a water quality detector, wherein the filtration chamber is provided with an inlet pipe, and the filtration chamber is The primary sedimentation tank is connected to the bio-filter chamber, and the filter chamber is provided with a filter membrane. The upper end of the bio-filter chamber is provided with a motor, and the motor is connected. There is a stirring shaft that drives the stirring blade provided in the biological filtering chamber to rotate, and a water quality detector is arranged at the water outlet of the lower end of the biological filtering chamber.

Further, an air compressor is disposed at an upper end of the biological filter chamber, and the air compressor is connected to the biological filter chamber through an air guiding tube.

Further, a control switch is disposed at a lower end of the water quality detector, a return pipe is disposed on a left side of the control switch, and a water recovery pipe is disposed on a right side of the control switch, and the return pipe is connected to the primary sinking tank.

Further, the water quality detector cooperates with the control switch.

Further, the inlet pipe is provided with an on-off valve.

The invention has the advantages that the system has the advantages of simple structure, can recover and reuse the waste water generated by marine aquaculture, and reduces the discharge amount of the drainage wastewater, thereby effectively reducing the pollution of seawater, saving energy and reducing consumption, and improving the system. Breeding the environment and contributing to the sustainable development of marine resources.

detailed description

The invention will now be further described with reference to the accompanying drawings.

As shown in Fig. 1, a marine aquaculture wastewater recovery and treatment system comprises a filter chamber 2, a primary sedimentation tank 3, a biological filtration chamber 4 and a water quality detector 11, and the filtration chamber 2 is provided with an inlet pipe 1, a filtration chamber 2 and a primary sedimentation tank. Correspondingly, the primary sedimentation tank 3 is connected to the biological filter chamber 4, and the filter membrane 5 is arranged between the filter chamber 2 and the primary sedimentation chamber 3. The upper end of the biological filter chamber 4 is provided with a motor 6, and the motor 6 is connected with a stirring shaft 7 The stirring shaft 7 drives the stirring blade 8 provided in the biological filter chamber 4 to rotate, and the water detecting device 11 is disposed at the water outlet of the lower end of the biological filtering chamber 4. An air compressor 9 is disposed at an upper end of the biological filter chamber 4, and the air compressor 9 is connected to the biological filter chamber 4 through the air guiding tube 10. The lower end of the water quality detector 11 is provided with a control switch 12, and the return switch 14 is disposed on the left side of the control switch 12. A water recovery pipe 13 is disposed on the right side of the control switch 12, The return pipe 14 is connected to the primary settling tank 3, the water quality detector 11 is matched with the control switch 12, and the inlet pipe 1 is provided with an on-off valve 15.

When the wastewater passes through the biological filter chamber, it passes through the water quality tester. If the water quality does not meet the standard, the water quality tester transmits the information to the control center, and the control center transmits the signal to the control switch, and the control switch opens the return pipe to make the water not reach the standard. Return to the primary settling tank and re-treat; otherwise, the control switch opens the water recovery pipe so that the treated water can be recycled.

The system has a simple structure, can recycle and reuse the wastewater generated by marine aquaculture, and reduces the discharge of wastewater discharged by the drainage, thereby effectively reducing the pollution of seawater, saving energy and reducing consumption, improving the breeding environment, and benefiting the ocean. Sustainable development of resources.

The above is only the embodiment of the present invention, and is not intended to limit the scope of the invention, and the equivalent structure or equivalent process transformation of the present invention and the contents of the drawings may be directly or indirectly applied to other related technologies. The fields are all included in the scope of patent protection of the present invention.
