Description

Technical Field

[0001] The invention relates to aquaculture wastewater treatment and reuse equipment, in particular to an aquaculture wastewater automatic treatment device based on neural network accelerated flocculation sedimentation. Background Art

[0002] With the rapid development of aquaculture, the resulting ecological and environmental pollution issues have received increasing attention, especially the wastewater generated by aquaculture. In summary, its harm is mainly to aquatic products and damage to the water environment. With the increase of aquaculture time, the concentration of pollutants such as nitrogen and phosphorus in the water body continues to increase. If they are not properly treated, these nitrogen and phosphorus pollutants will reduce the dissolved oxygen in the water ecological environment, leading to the growth of bacteria and microorganisms, and ultimately causing eutrophication of the water body and polluting the surrounding ecological environment.

[0003] In order to effectively alleviate the problem of ecological and environmental pollution, physical, chemical and biological treatment technologies have been applied to the treatment of aquaculture wastewater. Biological treatment of aquaculture wastewater mainly uses microorganisms and autotrophic plants such as algae and aquatic plants to improve water quality, solve residual bait and aquatic animal metabolites, and thus achieve a decontamination effect. Compared with physical and chemical process technologies that are prone to secondary pollution, high energy consumption and high treatment costs in the treatment of aquaculture wastewater, biological treatment technology has the characteristics of wide adaptability, no secondary pollution, renewability and strong ecology in the treatment of aquaculture wastewater. However, biological treatment lacks experience in large-scale aquaculture wastewater treatment, has a long treatment cycle and occupies a large area, and is easily restricted in actual operation.

[0004] Therefore, the physical and chemical process technologies for treating aquaculture wastewater are prone to secondary pollution, high energy consumption, high treatment costs, and biological treatment is insufficient for large-scale aquaculture wastewater treatment, with long treatment cycles and large floor space, which are easily restricted in actual operation. Magnetic coagulation technology has the advantages of fast treatment speed, high treatment efficiency, large treatment volume, wide adaptability, small floor space, low energy consumption, convenient operation and management, and high degree of automation. It has a wide range of application value, and after treatment, the main indicator substances COD, TP, TN and SS can be quickly removed, and its advantages are incomparable. Therefore, applying magnetic coagulation technology to the study of aquaculture wastewater can improve the treatment and reuse of aquaculture wastewater.

[0005] Intelligent control is a higher control method evolved from automatic control. It integrates intelligent algorithms and control systems and can have self-learning, self-adaptation and self-organization functions. If the intelligent control system can be integrated into the aquaculture wastewater treatment device, it can not only accurately control various devices in the system to quickly treat aquaculture wastewater, but also strictly control the inflow, treatment and discharge of aquaculture wastewater, so as to make the aquaculture wastewater treatment more efficient and better used. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a device for automatically treating aquaculture wastewater by accelerating flocculation and sedimentation based on a neural network.

[0007] In order to solve the above problems, the technical solution adopted by the present invention is:

[0008] A device for automatically treating aquaculture wastewater by accelerating flocculation and sedimentation based on neural networks is characterized in that: in view of the fact that physical and chemical process technologies for treating aquaculture wastewater are prone to secondary pollution, high energy consumption, high treatment costs, and that biological treatment methods are insufficient for large-scale aquaculture wastewater treatment, have long treatment cycles and occupy a large area, and are easily restricted in actual operation, the device can be automatically and accurately regulated according to actual conditions, and has a high degree of integration, is simple to operate and easy to maintain. Through the built-in neural network model, each operating component in the device is accurately regulated, thereby greatly improving the efficiency of treating aquaculture wastewater on the basis of strictly controlling the water quantity and quality. The device consists of an aquaculture wastewater collection unit, a filtration unit, a magnetic coagulation treatment unit, a sewage discharge unit, a water purification unit, and an intelligent allocation unit. It includes a box body, a water inlet pipe, an electric valve, a componentized filter, a water level monitor, an intelligent water pump, a fan-shaped agitator, a magnetic coagulant dosing device, a magnetic coagulant storage tank, a chemical delivery pipe, a COD sensor, an ammonia nitrogen sensor, an electromagnetic relay, a Y-type magnetic plate, a sludge baffle, a sewage pump, a sewage pipe, an activated carbon layer, a water outlet pipe, a control operation panel, and a controller.

The unit is located at the left end of the box body, and the aquaculture wastewater flows into the filter unit through the inlet pipe. The componentized filter net inside the filter unit further filters the impurities contained, and the filtered water flows into the aquaculture wastewater collection unit. When the water level monitor detects that the water volume in the aquaculture wastewater collection unit reaches the corresponding threshold, the information is fed back to the intelligent control unit, and the intelligent controller sends a signal to close the electric valve and drive the intelligent water pump to send the collected wastewater to the next unit for treatment.

The unit is located in the middle of the box, and the intelligent water pump connected by the left water pipe further replenishes the water source for the treatment unit. When the wastewater transported by the intelligent water pump reaches the threshold of the water level monitor in the magnetic coagulation treatment unit, the COD sensor and the ammonia nitrogen sensor detect the water quality information of the treatment unit and transmit the signal to the intelligent allocation unit. The intelligent allocation unit drives the fan-shaped agitator and the magnetic coagulant dosing device to work by analyzing and processing the feedback information.

[0011] The sewage discharge unit is composed of an electromagnetic controller, a Y-shaped magnetic plate, a sludge baffle, a sewage pump and a sewage pipe. The unit is located below the magnetic coagulation treatment unit. The Y-shaped magnetic plate generates a magnetic field under the action of the electromagnetic controller and accelerates the precipitation speed of the flocculent wrapped by the magnetic seed. The high-concentration precipitated waste liquid is discharged through the sewage pipe under the action of the sewage pump.

[0012] The water purification unit is composed of a tank, a water pipe, an activated carbon layer and a water outlet pipe. The unit is located at the right end of the box. The intelligent water pump pumps the wastewater treated by the magnetic coagulation treatment unit into the water purification unit. The activated carbon layer installed inside the tank is used to adsorb and filter the soluble substances and organic pollutants that have not been completely precipitated. The further purified wastewater is discharged to the required place through the water outlet pipe for reuse.

The controller can control the opening and closing of the electric valve, the intelligent water pump, the fan-shaped agitator and the magnetic coagulant dosing device. The central processing unit can integrate the information fed back by the water level monitor, the COD sensor and the ammonia nitrogen sensor, and use the built-in neural network model for precise regulation. The drive controller controls the magnetic coagulant dosing device to add an appropriate amount of medicine, and controls the fan-shaped agitator to evenly mix the medicine with the aquaculture wastewater to be treated.
