Problems solved by technology

In addition, in order to filter wastewater, a filter mesh structure needs to be installed in the holes. Under the action of centrifugal force, granular waste is easily stuck in the filter holes of the filter mesh structure, causing the holes to be blocked.
Therefore, after long-term use, the effect of pore filtering wastewater is not good

Embodiment Construction

[0020] like figure 1 , a solid-liquid separation system of aquaculture wastewater ammonia nitrogen treatment system, including a cylinder 10 and an auger 20 arranged in the cylinder, the cylinder is fixedly arranged, the cylinder is inclined, the shaft 21 where the auger is located is connected to the motor, and the cylinder is From the bottom to the top, the inner diameter gradually increases. The feed port 11 on the cylinder is set above the bottom of the auger, the water outlet 12 on the cylinder is set below the bottom of the auger, and the outlet 13 on the cylinder is located at the bottom of the auger. Set at the top of the auger.

[0021] According to the patent document of Application Publication No. CN 111977902 A, due to the existence of the blades 302 , the waste water and waste enter the opening 401 of the drum 4 in a batch-by-batch manner. The present invention is a substitute for the solid-liquid separation system in the patent document of application publicatio...

Abstract

The invention discloses a solid-liquid separation system of an ammonia nitrogen treatment system for aquaculture wastewater, comprising a cylinder and an auger arranged in the cylinder. From the bottom to the top, the inner diameter gradually increases, the feed port on the cylinder is set above the bottom of the auger, the water outlet on the cylinder is set below the bottom of the auger, and the discharge port on the cylinder is set at the bottom of the auger. Dragon's top position. The waste water entering the cylinder can flow down to the water outlet along the cylinder, and the wastes stay in different positions of the cylinder due to the shape and size. The auger rotates, which drives the waste material to move upward along the cylinder, and leaves the cylinder through the discharge port. Compared with the prior art, the present invention does not open holes on the cylinder, so as to avoid wastes from clogging the holes and affecting the filtration of waste water.

Description

technical field [0001] The invention relates to ammonia nitrogen treatment equipment in waste water. Background technique [0002] The patent document of the application publication number CN 111977902 A discloses a COD and ammonia nitrogen treatment system in aquaculture wastewater. The drum 4 of the solid-liquid separation system is provided with an opening 401, and the circumferential outer wall of the drum 4 is provided with a number of holes 402. The rotating drum 4 is provided with a rotating shaft three 404, the rotating shaft three 404 is provided with an auger 403, the two ends of the rotating shaft three 404 are connected with the motor three 405, and the bottom of the rotating drum 4 is respectively provided with a solid material recovery tank 5 and a liquid material recovery tank 6 ( Description of specific embodiments [0038]). When a batch of waste water flows into the rotating drum 4 along the opening 401, the control motor three 405 drives the rotating shaft ...
