Automatic pollution discharge device for aquaculture

Abstract

The invention discloses an automatic pollution discharge device for aquaculture, and relates to the technical field of pollution discharge devices. The device comprises a treatment pond and a sewage discharging pond, wherein the sewage discharging pond is arranged beside the treatment pond; a sewage discharging pipe is arranged on the lower portion of the sewage discharging pond in a penetrating mode; a scraping assembly, a first baffle, a spraying assembly, a transmission assembly, a brushing assembly and a locking assembly are arranged on the treatment pond; a plurality of air inlet holes are evenly formed in the bottom of the treatment pond; a notch is formed in one side of the upper portion of the treatment pond; the first baffle is arranged in the notch in a sliding mode; the spraying assembly is arranged above the sewage discharging pond; the brushing assembly is arranged between the spraying assembly and the sewage discharging pond; and the transmission assembly is arranged between the U-shaped plate and the spraying assembly. According to the device, air is uniformly conveyed into micro-polluted water from the bottom of the treatment tank to provide sufficient dissolved oxygen for a water body, and bubbles can adsorb suspended particles with small particle sizes in sewage in the rising process, so that the effect of removing impurities is achieved, and the practicability of the device is improved.

Description

Technical field [0001] The present invention relates to the technical field of sewage devices, in particular, to a aquaculture automatic sewage device. Background technique [0002] Aquaculture industry is human utilization of waters that can be used in breeding, in accordance with the ecological habit of breeding objects, and use aquaculture technology and facilities to use aquaculture technology and facilities, engage in aquaculture, plant breeding, one of the agricultural production departments. Pollutants in the current cultured water include: organic matter, ammonia nitrogen, nitrite, nitrate, active phosphate, sulfide, and the like. Its characteristics are: high water volume, less variety of pollutants, small content, mainly organic and nitrogen, phosphorus, sulfur and other nutrients, most of the aquaculture wastewater belongs to microbulin, and the pollution load is relatively low. Treatment is also easier, and some farmed wastewater does not even require physical chemica...

AI Technical Summary

Problems solved by technology

[0005] (1) The existing aquaculture automatic sewage discharge device is easy to cause blockage when removing suspended particles in the sewage through the filter screen, which makes the filtering effect poor and the water quality of the sewage treatment is not up to standard
