Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture circulating water or tail water treatment, in particular to a full-automatic sewage discharge vertical flow solid-liquid separator. Background Art

[0002] It is very important to quickly separate and collect the leftover bait and feces of fish and shrimp in aquaculture systems. During production operations, aquaculture enterprises often bring some floating debris (such as plastic bags, fiber ropes, plastic bottles, suspended leftover bait, fish feces, dead aquaculture bodies, etc.) into the water. Although there is a grid at the front end of the microfilter, the grid has a low interception rate for some small floating objects, and there are still floating objects flowing into the microfilter, which has a serious impact on the operation of the microfilter (such as high liquid level alarm shutdown). At the same time, a large amount of leftover bait and fish feces also increase the load on the microfilter and subsequent treatment systems.

[0003] The utility model patent with application number 202222238622.0 and name of aquaculture tailwater purification device discloses an aquaculture tailwater purification device, including multiple tailwater sedimentation tanks, flowmeters, primary sedimentation units, purification units, strengthening units and multiple control switches. Multiple tailwater sedimentation tanks are used to place tailwater with different pollution concentration loads; the flowmeter is connected to the outlet of multiple tailwater sedimentation tanks to control the hydraulic retention time; the inlet end of the primary sedimentation unit is connected to the outlet end of the flowmeter; the inlet end of the purification unit is connected to the outlet end of the primary sedimentation unit; the inlet end of the strengthening unit is connected to the outlet end of the purification unit; and multiple control switches are located at the outlet end of multiple tailwater sedimentation tanks, the primary sedimentation unit and the purification unit, which are used to select the pollution concentration load of the tailwater flowing into the flowmeter and control the ratio of the primary sedimentation unit, the purification unit and the strengthening unit. However, the technical solution adopts the sedimentation method and cannot effectively treat the scum in the aquaculture tailwater. Utility Model Content
