Description

The next-generation smart filtration system for circulation filtration of fish farms {THE NEXT GENERATION SMART FILTERING SYSTEM FOR RECIRCULATION FILTRATION OF AQUAFARM}

The present invention is a fish that minimizes pollution of the surrounding environment due to fish farming, such as the sea or river, by reducing the use of aquaculture water by filtering and recirculating the aquaculture water in the fish farm, and in particular, significantly reducing the amount of discharged water after use. It relates to a next-generation customized smart filtration system equipped with a communication function to provide the optimal filtration system for aquaculture and to remotely monitor and control all these processes.

Most domestic fish farms exist near water sources such as the sea or rivers, and they are constructed as a one-time circulation system that draws in water for fish culture, circulates the farm, and then discharges it back to the water source. However, since this method is a method in which water is circulated for 24 hours, there is a problem in that the amount of water used is very high and the energy cost is increased accordingly. There has always been a problem of secondary pollution that directly contaminates the ecosystem around the sea or river as pollutants such as excrement and residual antibiotics from the input of antibiotics are included in the discharged water as they are and are discharged to the water source.

In order to improve these problems in advanced fish farming countries such as Denmark and Norway, we have developed and applied aquaculture water recirculation system to which the concept of circulating filtration aquaculture has been applied, greatly reducing water consumption and minimizing discharge water to solve the above problems. Alternatively, since it is possible to farm fish inland rather than near a water source, efficient fish farming facilities have been established regardless of location and competitiveness is secured in economic terms.

However, in the case of Korea, cage-type farms in the sea or river have been relied on because they are very advantageous in terms of installation and maintenance costs. However, recently, they are very vulnerable to temperature changes, green algae, and red algae, and the cost of damage is geometrical every year. Cage-type aquaculture, which is rapidly increasing, is being avoided, and aquaculture methods on land are spreading. However, as mentioned above, domestic land aquaculture farms exist near the water source, and they tried to minimize the damage caused by changes in the external environment that occurs like an annual event by simply changing the location from the sea or river to the land, but a filtration system suitable for this according to the dense aquaculture type. As a result, a secondary problem arises, and there is no way to solve it.

Accordingly, domestic related research institutes and related local governments such as Gyeongsangnam-do and Jeollanam-do are continuously conducting research to solve these problems, but they are looking for solutions through monitoring the occurrence of pollution and upgrading various control functions. In terms of management, it is still at the level of rationalization of the farm management system with a defensive concept, and a fundamental solution to the active concept of an active concept of removing the source of pollution has not been presented. That is, the current aquaculture method of the one-time circulation method uses a very large amount of aquaculture water, so any filtration system that has been developed so far requires a filtration device that costs a lot of money, and there is a problem in the economic feasibility. This is because the filtration system cannot be applied.

In addition, since all processes performed in the fish farm are performed manually by man, there has been a limit in reducing the occurrence of huge labor costs and costs. Therefore, we propose a realistic plan for cost reduction by enhancing the convenience of farm operation by adding a fishbreeding control and monitoring function using the excellent domestic communication network.

An object of the present invention for solving the above-mentioned problems is to reduce the amount of aquaculture water used, minimize pollution due to discharge water, and in particular, provide an automated filtration system that enables efficient and economical remote monitoring and control, thereby burdening the investment cost of aquaculture fishermen It is to provide a next-generation smart filtration system that can be applied and utilized conveniently by minimizing the cost of production and reducing production costs.

The next-generation smart filtration system for purifying fish farms according to the present invention for achieving the above object applies functional ceramic filter disks to each stage and type of pollutants generated in the fish farm by filtering them according to the characteristics of the pollutants. By maximizing the filtration efficiency and recirculating the filtered treated water, the flow rate of the influent from the water source is reduced to reduce the energy cost as well as the production cost. , to provide a next-generation smart filtration system that can reduce management costs by remote monitoring and control with a mobile system, and also reduce labor costs through automation of management.

The next-generation smart filtration system for circulation filtration of a fish farm according to the present invention can reduce the cost of using aquaculture water and its energy cost by significantly reducing the amount of aquaculture water used in the fish farm, and each pollution through a step-by-step multi-stage filtration system It is possible to maximize the filtration efficiency of substances, and in particular, it can suggest a plan to prepare for the increasingly stringent domestic environmental pollution-related laws and regulations by minimizing the amount of discharged water.

In addition, by having control devices and detection devices for each component and function of the filtration system, it is automatically monitored and controlled by a computer, and furthermore, by enabling remote monitoring and control functions through the Internet and mobile devices, labor costs and management costs are reduced at the same time. can do.

Hereinafter, a next-generation smart filtration system for circulation filtration of a fish farm according to a preferred embodiment of the present invention will be described in detail.

In the next-generation smart filtration system for circulation filtration of fish farms according to a preferred embodiment of the present invention, in a first step, each filter manufactured by mixing a functional ceramic material is inserted into a silicon band, and then a perforated metal plate is already perforated. After inserting into the filter, fill the filter and the space around the filter with activated carbon beads, cover the upper surface with a micro-perforated plate through which water can pass, and assemble the filter cartridge.

In the second step, the filter cartridge assembled in a pipe-type metal chamber of a certain standard is installed at intervals equal to the thickness of the cartridge. The reason for installing the cartridge at the same interval as the thickness of the cartridge is that when the cartridge mounted inside the chamber is in full contact, the filtering processing speed is lowered, and in particular, when the water permeability is lowered by the filtered contaminants, replacement or cleaning is required. This is to make it easier to identify the filter cartridge. This has the effect of reducing operating costs such as replacement cost of filter cartridges in the long term.

In step 3, the filtration chamber with each functional filter cartridge is installed in a structure made of a metal profile in consideration of its function and connected with a pipe. At this time, the filtration chamber to filter out solid fine suspended substances from the location close to the receiving part of the polluted water, the filtration chamber to filter out oxidized pollutants that are relatively easy to filter oxidized by ozone such as heavy metals, and trace chemical pollutants such as antibiotics and a filtration chamber to remove residual ozone, etc., installed so that contaminated water can pass through.

At this time, the water acquisition part of the filtration chamber is piped to be located at the upper part of the side of the chamber, and the drain part of the filtration chamber is piped to be located at two places below and above the rear side. During normal operation, the filtered water drained from the chamber is drained through the drain pipe located at the upper part of the back side, so that the stagnation time is allowed so that the contaminated water can be sufficiently filtered in the filtration chamber. The drain pipe located in the lower part of the rear side is provided for the purpose of discharging residual polluted water during emergency stop or during regular maintenance and maintenance period and when necessary. In addition, a manual cock may be provided separately in the drain port at the bottom of the rear side to check the condition of the contaminated water filtered at the site from time to time.

In addition, each filtration chamber is not installed on the profile structure horizontally, but the inlet part is maintained at an inclination of about 1 to 3 degrees from the drain port, so that even when the residual polluted water is discharged, it is installed so that it can be completely discharged without any residue.

A control valve is installed in the drain part of each filtration chamber to remotely select the upper and lower drain pipes, and a signal output sensor is attached to continuously monitor the amount of total oxide contained in the filtered water, and the flow rate of the discharged water By detecting , it is possible to monitor the filtering status inside the filtration chamber.

In addition, a turbidity sensor is installed at the front inlet and rear outlet of the filtration system so that the filtration status can be checked frequently.

A control valve is provided at the rearmost outlet to select whether to discharge the filtered water or to recycle it by returning it to the raw water receiving part of the farm.

The operation panel is equipped with an automatic mode and a manual mode for on-site operation. The automatic mode maintains the specified process flow according to the already programmed state. When set to manual mode, the operation of each pump or valve located in the middle of the operation panel is provided. It can be operated by selectively turning ON/OFF using a switch.

In addition, the field and remote selection switches of the operation panel are set to the field in the case of normal operation, and if necessary, the current operation status can be monitored through a computer or mobile device through the Internet. The mode is switched to the administrator mode given the access right, and the remote control mode is activated through the registered ID and password, and the authentication process that confirms the identity of the person. Since the remote control mode can control all equipment regardless of the situation in the field, it is performed through a reconfirmation procedure every time an operation instruction is made. The operation panel is equipped with the function to connect the cctv screen that may be installed in the field. In addition, the switch for control of pumps and valves should be provided with an extra 50% or more of the minimum number of facilities for opening and intermittent control of various detour lines installed to prepare for failure of driving equipment.

As a result of verifying the performance of the filter cartridge through many in-house experiments, it has been verified that at least 20 minutes is required for the trial calculation of the contact reaction between the contaminated water and the filter as a whole, and a contact time of at least 7 minutes is required for each filtration chamber. Therefore, the design should be designed in consideration of the size of the pipe and the flow rate per minute according to the treatment capacity of the contaminated water. Engineers who are usually engaged in the water treatment field can easily understand and design.
