Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, specifically to a microwave photo-oxygenation aquaculture drinking water filtration and disinfection device. Background Technology

[0002] Water is an indispensable nutrient for the life processes of livestock and poultry, participating in physiological activities such as body temperature regulation, nutrient transport, and waste excretion. All life processes of livestock and poultry are inseparable from water, and the quality of water directly affects their health and productivity. Currently, drinking water sources for livestock and poultry include surface water, groundwater, and tap water.

[0003] However, due to the impact of swine fever and avian influenza, drinking water for livestock and poultry generally requires disinfection and sterilization. Commonly used treatment technologies for livestock and poultry drinking water mainly include physical, chemical, and biological treatment methods. Modern commonly used technology is membrane filtration, a physical method. Membrane filtration technology refers to pressure-driven membrane separation, also known as membrane separation technology, and is an advanced method of deep water treatment. Under certain pressure, when the raw liquid flows over the membrane surface, the numerous tiny pores on the membrane surface only allow water and small molecules to pass through, becoming the permeate. Substances in the raw liquid with a volume larger than the membrane pore size are retained on the feed side of the membrane, becoming the concentrate, thus achieving the separation and concentration of the raw liquid. Membranes can retain large-diameter molecules or fine particles, including bacteria and viruses. Therefore, membrane filtration can effectively remove bacteria, viruses, and other microorganisms from water, as well as remove odors and harmful heavy metals, improving water quality.

[0004] Membrane filtration technology has the following shortcomings in practical applications:

[0005] 1. The input, operation and maintenance costs are high, the process is complex, maintenance is complicated, and concentrated liquid is generated during operation;

[0006] 2. It has a relatively high operating power because membrane filtration technology requires a certain pressure to operate;

[0007] 3. RO membrane filtration also filters out trace elements in the water. Utility Model Content

Detailed Implementation

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] This utility model proposes a microwave photo-oxygenation aquaculture drinking water filtration and disinfection device, such as... Figure 1 and Figure 2 As shown, it includes a filtration system, a primary disinfection system, and a secondary disinfection system arranged in sequence.

[0026] The entire aquaculture drinking water treatment system is made of 304 stainless steel. The equipment as a whole is made of 304 stainless steel plates and adopts a continuous treatment process, which involves three stages of treatment (filtration, primary disinfection, and secondary disinfection).

[0027] 1. Filtration system

[0028] The filtration system includes a filter chamber 1 and a rotary drum filter 2. The inlet of the rotary drum filter is connected to the water source pipeline for the aquaculture drinking water to be treated via flanges and other components. When the liquid enters the drum, particles and suspended solids smaller than the mesh size are separated through physical filtration, thus achieving liquid filtration. The rotary drum filter typically includes a drum that slowly rotates. A backwash pump draws filtered water to backwash the filter screen. The washed-off particulate matter is collected in a backwash water collection tank inside the equipment and discharged through a drain pipe. The filtration system operates normally during backwashing. Particles smaller than the mesh size are trapped inside the drum, while larger particles are discharged through the outlet pipe.

[0029] The filtration chamber is also equipped with a filter cake outlet 17 and a cleaning spray inlet 18, with a drain pipe connected to the filter cake outlet. Each disinfection chamber is equipped with an air vent valve at the bottom.

[0030] Cleaning the drum is an important part of the normal operation of the equipment. There are usually a variety of cleaning methods to choose from, such as mechanical cleaning, chemical cleaning and water rinsing.

[0031] This invention uses a rotary drum filter, which has the following advantages:

[0032] (1) High-precision filtration: It can effectively remove suspended solids in water and is suitable for occasions with high water quality requirements.

[0033] (2) Automatic backwashing: The filter screen is backwashed by drawing water from the filter outlet through a backwashing pump, which reduces manual intervention and improves the automation level of the equipment.

[0034] (3) Simple structure: The structure of the drum filter is relatively simple, and it is easy to maintain and operate.

[0035] (4) Small footprint: The high efficiency of filtration and the compact design result in a relatively small footprint, making it suitable for occasions with limited space.

[0036] (5) Low operating costs: The high utilization rate of filter cloth and the optimization of operating costs result in low overall operating costs.

[0037] 2. Disinfection system

[0038] The primary and secondary disinfection systems have the same composition and working principle. Each disinfection system consists of three parts: disinfection chamber 3, aeration device, and electrical box (electrical control device 6).

[0039] The disinfection room is equipped with a disinfection pool 5 and a microwave electrodeless lamp box 4 located above the disinfection pool. A resonant cavity is formed inside the microwave electrodeless lamp box, and the microwave electrodeless lamp is located in the middle of the resonant cavity.

[0040] The primary disinfection system is equipped with an exhaust port 10, an exhaust pipe 11, and a blower 12. The secondary disinfection system's disinfection tank has an outlet 14 for discharging the treated aquaculture drinking water. The aeration device consists of a microporous aeration disc 7, an air pump, an aeration pipe 8, and a blower 12, used to aerate the water in the disinfection tank. The air inlet of the aeration pipe is located at the bottom side of the disinfection chamber, leading to the blower's outlet. The blower's air inlet leads to the outlet of the secondary disinfection system's disinfection chamber via a pipe. An air supply port 10 is located above the duckbill-shaped waterfall device in the primary disinfection system. Air enters the primary and secondary disinfection chambers through the air supply port, and after being irradiated by the electrodeless lamp, it produces free oxygen. This oxygen combines with oxygen to produce ozone. The ozone is drawn in through the blower's air inlet, pressurized, and released into the water via the pipes into the microporous aeration disc. The lower aeration section includes an electrodeless lamp, an aeration disc, an aeration pipe, an electrodeless lamp box, and an aeration pipe system. The filtered water flows through the upper part of the light box via a duckbill-shaped waterfall device 13, and is uniformly irradiated by ultraviolet light generated by the lamps. Simultaneously, the bottom microporous aeration disc releases ozone into the water. The aeration section increases the contact area between the water surface, the upper ozone chamber, and ultraviolet radiation, and also accelerates the water circulation speed, improving the overall reaction rate of the equipment.

[0041] The electrical box mainly contains a microwave generating module, a control module, and a heat dissipation device 16. The microwave generating module generates microwaves to provide energy for the microwave electrodeless lamp inside the microwave electrodeless lamp box. The control module can monitor and control each electrical component in real time, and the heat dissipation device is used for electrical heat dissipation.

[0042] The microwave emission port is directly opposite the center of the microwave electrodeless lamp holder. The microwave electrodeless lamp works by filling a sealed shell made of quartz glass with a mixture of evaporable metals and rare gases. The rare gases are used to excite plasma discharge. When the electrodeless lamp is placed in a microwave field, the rare gases are excited to generate low-pressure plasma. Through plasma discharge, the evaporable metals become vaporized, generating more plasma, increasing plasma pressure, releasing more energy, and forming UV light. UV light is electromagnetic radiation with a wavelength shorter than visible light but longer than X-rays. The wavelength range of UV light in the electromagnetic spectrum is 10-400 nm. This range begins at the short-wavelength limit of visible light and overlaps with the long-wavelength wavelength of X-rays. UV light is divided into A-rays, B-rays, and C-rays (UVA, UVB, and UVC), with wavelength ranges of 400-315 nm, 315-280 nm, and 280-190 nm, respectively. The present invention uses ultraviolet light with a wavelength of 185nm to generate O3 (ozone) and ultraviolet light with a wavelength of 254nm to lyse bacteria, viruses, etc.

[0043] The microwave generator module produces an electromagnetic field, which kills bacteria through the combined effects of thermal and biological effects. The thermal effect of microwaves on bacteria alters proteins, depriving bacteria of the conditions necessary for nutrition, reproduction, and survival, leading to their death. The biological effect of microwaves on bacteria involves the microwave electric field changing the potential distribution across the cell membrane, affecting the concentration of electrons and ions around the cell membrane, thereby altering the cell membrane's permeability, causing malnutrition and death. Furthermore, microwaves can induce genetic mutations in the RNA and DNA of bacteria, which are normally grown and stably reproduced through the relaxation, breakage, and recombination of numerous hydrogen bonds.

[0044] After being filtered by the filtration system, the water flows through the duckbill-shaped waterfall device into the first-stage disinfection system's electrodeless lamp box and then into the first-stage disinfection pool. It then flows through the duckbill-shaped waterfall device of the second-stage disinfection system again into the second-stage disinfection system's electrodeless lamp box and into the second-stage disinfection pool, before finally flowing out for drinking.

[0045] An air inlet is located at the top of the duckbill-shaped waterfall device in the primary disinfection system. Air enters the equipment through this inlet and is irradiated by the electrodeless lamps of the primary and secondary disinfection systems. This generates free oxygen molecules that combine with oxygen to produce ozone. The ozone and mixed indoor gases are drawn into the blower through the blower inlet. After being pressurized by the blower, the ozone is released into the water in the primary and secondary disinfection tanks through pipes and microporous aeration discs. The equipment adopts an overall sealed design, so there will be no ozone leakage. The microporous aeration discs in the primary and secondary disinfection tanks are at the same depth in the water to balance the pressure and prevent uneven aeration.

[0046] The electrical control part of this utility model also includes sensors, cables, wires, etc., to realize the electrical signal connection of various electrical devices, achieve the purpose of real-time monitoring of data, and real-time adjustment of relevant process parameters, which will not be elaborated here.

[0047] This invention provides a microwave photo-oxidation aquaculture drinking water filtration and disinfection device. It employs multiple technologies to synergistically treat aquaculture drinking water, effectively killing bacteria and viruses while significantly inhibiting their reproduction. The device has a small footprint, is simple and convenient to operate, reducing initial investment and subsequent maintenance costs. No chemicals need to be added during the treatment process, thus eliminating drug residue issues. This microwave photo-oxidation aquaculture drinking water treatment device (unaffected by pH and temperature) maintains good treatment performance even in harsh environments. It utilizes a multi-stage combined treatment process with high integration, facilitating the upgrading and renovation of existing aquaculture drinking water treatment systems. In addition to basic filtration and disinfection functions, it also adds decolorization and deodorization functions. It features low energy consumption, low investment, energy saving, convenient installation, short construction period, and diverse application scenarios.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments do not limit this utility model in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
