[0002] The agricultural aquaculture wastewater refers to the wastewater discharged in the process of aquaculture, which contains a large amount of organic matter, nitrogen, phosphorus and other nutrients and microorganisms, and belongs to a kind of harmful pollutants. If the agricultural aquaculture wastewater is directly discharged without treatment, it will cause serious pollution to water, air and soil, endangering the environment and human health. The existing users of aquaculture will use the aquaculture wastewater treatment device to ensure that the wastewater will not pollute the environment and guarantee the living environment quality of the breeding personnel.

[0003] In the process of treating the agricultural aquaculture wastewater, the conventional method is to first add special reagent, then promote the wastewater to be solid-liquid separated through the stirring device, then transfer the separated liquid and sediment to the sedimentation tank for sedimentation treatment, and finally discharge the liquid and sediment through the separation device. This series of steps means that the wastewater treatment process needs the participation of multiple devices, which not only prolongs the overall treatment time, but also correspondingly increases the treatment cost.
