Small aquaculture sewage treatment system

Abstract

The invention discloses a small aquaculture sewage treatment system in the technical field of sewage treatment.The small aquaculture sewage treatment system comprises a purification box, the top of the purification box is fixedly connected with a feeding box, the interior of the feeding box is divided into a plurality of loading areas through partition plates, and the loading areas are arranged at equal intervals in the length direction of the feeding box; a baffle plate is arranged at the bottom of the feeding area, the baffle plate is rotationally connected with the feeding box, and the purification box and the feeding box are jointly provided with a quantitative feeding assembly; the quantitative feeding assembly can automatically add a proper amount of a flocculating agent into the purification box according to the adding amount of sewage in the purification box; according to the invention, the flocculant can be added more simply and efficiently.

Description

Technical field [0001] The present invention relates to the field of sewage treatment technology, specifically a small aquaculture sewage treatment system. Background [0002] Aquaculture is the use of waters available for aquaculture by humans, in accordance with the ecological habits of the breeding object and the requirements of the environmental conditions of the waters, the use of aquaculture technology and facilities, engaged in aquatic economic animal and plant breeding, for one of the agricultural production departments. [0003] The invention patent in the field of sewage treatment technology is disclosed in the prior art, of which the invention patent with application number CN202020927600.3 is disclosed, and the aquaculture sewage treatment equipment is disclosed, involving the field of sewage treatment technology. Including the sedimentation mechanism, the primary filter mechanism and the adsorption mechanism, the side of the sedimentation mechanism is fixed with the...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the flocculant is added manually. When the amount of sewage in the sedimentation tank is small or not full, it is easy to cause too much or too little flocculant. Adding too much flocculant will affect the quality of the flocculant. If it reaches saturation, the water will become very viscous. At this time, the flocculant will not gather together and precipitate in the water, and it will easily block the filters and pipelines and other equipment, which will affect the treatment of sewage; and when the flocculant dosage is too small , the flocculation effect is not obvious, which will lead to the incomplete flocculation of impurities in the sewage, which will easily lead to incomplete sewage treatment; and the addition of flocculant is a one-time overall addition, which will easily cause the flocculant to accumulate in one position and cannot diffuse in the sewage Open, will greatly reduce the flocculation rate of debris in sewage
