In this embodiment, the treatment of the flocculated organic wastewater of livestock is mainly described as an example, and the organic wastewater of livestock coagulates soft organic substances in the organic wastewater of livestock into aggregates by the attraction of charges under the action of the biopolymer flocculation and the ionic coagulant aid:

A. and (3) filtering treatment: referring to fig. 1, 4, 7, 9-11, the present invention adopts a flat plate type filtering component, that is, the filtering plate 24, the feeding device 25 pumps the organic waste water of livestock and poultry passing through the pre-treatment device 5 into the groove 242 above each filtering plate 24, the vacuum treatment device 3 is started to make the inner chamber 241 form a negative pressure vacuum state, so that the liquid part (i.e. waste liquid) in the organic waste water of livestock and poultry is sucked into the liquid recycling bin 27 through the inner chamber 241 through the fine holes 243, and the coagulated part (i.e. waste particles) in the organic waste water remains in the groove 242 because the coagulated part (i.e. waste particles) cannot pass through the fine holes 243;

in the process of filtering treatment, the transmission device 1 continuously operates, and the first motor 124 drives one of the tooth blocks 122 to rotate, so that the chain 123 drives each filtering flat plate 24 to rotate, and thus each filtering flat plate 24 can pass through the lower part of the feeding device 25 one by one to receive organic wastewater;

when the transmission device 1 is operated, since each filtering plate 24 is driven, each communicating pipe 23 connected with each filtering plate 24 is also driven to rotate along with the filtering plate 24, then each communicating pipe 23 pulls the second outer disc 212 and the second inner disc 222 to rotate, and therefore each communicating air hole 226 is sequentially communicated with the air suction hole 224 and the air blowing hole 225, when the communicating air hole 226 is communicated with the air suction hole 224, each communicating air hole 226 performs a vacuum pumping action on the filtering plate 24 through the connected communicating pipe 23, so that the inner chamber 241 forms a negative pressure vacuum state, otherwise, when the communicating air hole 226 is communicated with the air blowing hole 225, each communicating air hole 226 performs a reverse pressure action of blowing air on the filtering plate 24 through the connected communicating pipe 23, so as to avoid the fine micro holes 243 being blocked by the granules;

in the present embodiment, the suction holes 224 correspond to eight of the communicating air holes 226, so that, by designing and arranging, the corresponding eight filtering plates 24 communicating with the communicating air holes 226 can simultaneously perform the filtering action of extracting the waste liquid, and eight of the filtering plates 24 horizontally disposed above the transmission device 1, as the filtering plates 24 rotate, when each filtering plate 24 communicates with the air blowing hole 225 and performs the reverse pressure action of air blowing, each filtering plate 24 is already driven to the upper side of the solid recycling bin 26, so that the waste particles on the grooves 242 and the fine particles blown out by the reverse pressure can fall into the solid recycling bin 26, thereby completing the filtering treatment effect of solid-liquid separation.

B. Ultrasonic treatment: referring to fig. 1 and 12, the inlet pipe 45 mixes the waste liquid in the liquid recycling tank 27 with ozone a and enters the first action region 411 in the action tank 41, and through the dispersing and shearing action of the low-frequency ultrasonic wave B generated by the low-frequency ultrasonic device 42 in the horizontal direction, bubbles of ozone a are crushed into smaller micro-bubbles, so as to increase the contact area with the waste liquid, increase the mixing degree and the mass transfer rate of ozone a, enhance the reaction between ozone a and organic matters in the waste liquid, and kill harmful germs in the waste liquid;

then enters the second action zone 412, and the residual ozone is decomposed by the high-frequency ultrasonic wave device 43 under the radiation of the high-frequency ultrasonic wave C generated in the horizontal direction to generate atomic oxygen and hydroxyl free radicals, so that the organic matters in the waste liquid can be further subjected to oxidative decomposition;

after the ozone a is sequentially treated by the low-frequency ultrasonic wave B and the high-frequency ultrasonic wave C, the oxidation capacity is enhanced, the horizontal directions of the low-frequency ultrasonic wave B and the high-frequency ultrasonic wave C can impact and change the flow direction of the ozone a and the waste liquid, the action time in the action tank 41 is prolonged, the organic matter is sufficiently oxidized, the acted ozone a and the acted waste liquid enter the temporary storage area 413, the waste liquid is led out to the recovery and purification device 6 by the liquid leading-out pipe 47, and the ozone a is led out by the gas leading-out pipe 48 and then recovered.

Compared with other prior art, the organic wastewater treatment system provided by the invention has the following advantages:

Referring to fig. 13, at least one ultrasonic oscillation device 28 may be installed below the filtering device 2, and the ultrasonic oscillation device 28 may emit ultrasonic waves to each filtering plate 24 after filtering, so as to vibrate fine waste particles in each filtering plate 24 by the oscillation action generated by the ultrasonic waves, thereby preventing each filtering plate 24 from being blocked.

Referring to fig. 1, the organic wastewater treatment system of the present invention can be connected to the pre-treatment device 5, wherein the pre-treatment device 5 pre-decomposes and acidifies the wastewater, then performs aerobic decomposition, denitrification and desulfurization, and then adds biological flocculation microorganisms to perform flocculation;

the treated waste liquid can enter the recovery and purification device 6 through the liquid delivery pipe 47, the recovery and purification device 6 is used for purifying water by using an activated carbon filter material adsorption method for the waste liquid, organic matters or toxic substances in the water are removed by adsorption, the water is purified, the adsorption of the activated carbon on the organic matters is influenced by the pore size distribution and the characteristics of the organic matters, the activated carbon is generally columnar particles, the specific surface area is large, the micropores are developed, the mechanical strength is high, the adsorption speed is high, the purification degree is high, the powder is not easy to remove, the service life is long, and the device is particularly used for deeply purifying the organic waste water of livestock and poultry to achieve the purposes of removing harmful substances such as odor, chlorine, cyanogen and various heavy metal ions and decoloring.
