It is mainly distributed in the Yangtze River and Pearl River systems in China and their affiliated lakes, reservoirs and ponds. It generally likes to live in the middle and lower layers of water and nearshore areas with abundant aquatic plants. It feeds on zooplankton in the fry stage and insects, earthworms, algae and duckweed in the juvenile stage. During the breeding process of grass carp fry, the water in the breeding pond needs to be circulated and filtered to ensure water quality and improve the stability of the breeding environment. The filtration steps mainly include physical filtration, biological filtration, sterilization and disinfection, oxygenation and temperature control, and water quality monitoring.

[0081] The working principle and use process of the present invention are as follows: when filtering the water in the pond for breeding grass carp fry, the in-and-out electric push rod 205 drives the in-and-out sealing frame 206 and the separation net barrel 208 to slide into the inner side of the interception limit barrel 203, and makes the in-and-out sealing frame 206 fit with the interception limit barrel 203, and the separation net barrel 208 fits with the interception limit barrel 203. The water in the water pool is extracted by the injection pump 225 through the injection linkage pipe 224, and the water is injected into the inner side of the separation net barrel 208. The separation net barrel 208 is driven by the transposition motor 207 to rotate along the in-and-out sealing frame 206, driving the water and the large The granular impurities rotate, separating the water and removing it to the inside of the intercepting and limiting barrel 203, and then injecting it into the inside of the fixed aeration tank 201 through the drainage linkage pipe 204. When the fixed aeration tank 201 is filled with liquid, the treatment pump 210 and the porous air injection pipe rack 209 continuously inject air into the fixed aeration tank 201, and the impurities suspended in the water are removed by aeration, and the mixed impurities in the water are separated from the water, achieving steady slag removal. The water flows along the intercepting and limiting barrel 203 to the position of the external fixed discharge pipe 222, achieving two-step continuous slag removal, and ensuring the efficiency of the slag removal treatment of impurities in the water;

[0082] During the aeration process, the collection net box 305 is magnetically fixed to the bottom end of the switching linkage frame 303 by connecting the electromagnet 304, and the lifting hydraulic cylinder 301 drives the switching motor 302 and the switching linkage frame 303 to rise, and the switching motor 302 drives the switching linkage frame 303 to rotate, so that the collection net box 305 is aligned to the position of the fixed aeration tank 201. At this time, the lifting hydraulic cylinder 301 drives the switching motor 302 and the switching linkage frame 303 to move downward, thereby inserting the collection net box 305 into the inner side of the fixed aeration tank 201. At the same time, the alignment electric slide 310 drives the alignment scraper 311 to move downward and insert it into the inner side of the fixed aeration tank 201. The slag pushing electric slide 308 drives the slag pushing linkage block 309 and the alignment scraper 311 to move, and the alignment scraper 311 pushes the impurities on the water surface into the inner side of the collection net box 305, thereby achieving steady slag cleaning.

[0083] The treatment valve 223 opens the external fixed pipe 222 to discharge the aerated water into the inside of the collection relay box 211. At this time, disinfectant is added into the collection relay box 211 through the fixed feeding barrel 314. The mixing motor 312 drives the mixing frame 313 to rotate, mixing the water and the disinfectant to sterilize the water. At this time, the fixed filter element 215 is inserted into the side end of the closing operation frame 214. The opening and closing electric push rod 213 drives the closing operation frame 214 and the fixed filter element 215 to move into the inside of the filtration treatment barrel 212. The fixed filter element 215 is steadily inserted into the inner side of the filter treatment barrel 212. The sterilized water is pumped into the inner side of the filter treatment barrel 212 by the injection linkage pipe 224 and the injection pump 225. The sterilized water gradually rises and is filtered through the fixed filter element 215 in the filter treatment barrel 212. The fixed filter element 215 is continuously filtered to intercept the small particles contained therein, so that the water is further filtered and treated. The filtered water flows along the external fixed pipe 222 into the inner side of the gas mixing treatment barrel 216. At this time, the condensation processor 217 cools the water to 20°C. At this time, the ozone generator 220 and the injection operation pipe 219 are used to inject ozone into the gas mixing treatment barrel 216. The mixing motor 312 drives the mixing rack 313 to promote the mixing of water and ozone to achieve ozone sterilization and algae removal. The treated water is injected into the inner side of the second gas mixing treatment barrel 216 through the injection linkage pipe 224 and the injection pump 225. At this time, the temperature control processor 218 raises the water temperature to 40°C, and cooperates with the mixing motor 312 drives the mixing rack 313 to stir the water, so that ozone is decomposed into oxygen, realizing ozone cleaning treatment. The treated water is injected into the third gas mixing treatment barrel 216 through the injection linkage pipe 224 and the injection pump 225. Oxygen is injected into the gas mixing treatment barrel 216 by the oxygen pump 221 and the injection operation pipe 219, and the water temperature is controlled at 27°C in conjunction with the temperature control processor 218 to achieve steady water treatment, and the external fixed pipe 222 is used to return the water to the breeding pool to ensure continuous purification and continuous water supply treatment.
