Closed circulation water system culture pond full-automatic and timing pollution discharging method and apparatus

Abstract

The invention relates to a closed circulation water system culture pond full-automatic and timing pollution discharging method and apparatus. The method comprises the following steps of building a pollution discharging pond outside the culture pond, forming a dirt collection pond on a recessed bottom of the culture pond, laying a pollution discharging pipe, communicating the dirt collection pond and the pollution discharging pond, and discharging dirt via a siphon principle of the pollution discharging pipe. The apparatus achieving the method comprises a circulating water supplying pipeline and a water discharging pipe in the culture pond, the dirt collection pond and the pollution discharging pond, wherein the pollution discharging pipe is arranged on the bottom of the dirt collection pond; the other end of the pollution discharging pipe extends to the external side of the culture pond and forms an inverted U-shaped pipe to be communicated with the pollution discharging pond; the upmost part of the inverted U-shaped pipe is further connected with a vacuum breakdown pipe and a vacuum pipeline; the vacuum breakdown pipe extends to the culture pond; and the vacuum pipeline is connected with a vacuum pump controlled by a computer program. Automatic pollution discharging can be achieved for the culture pond via the siphon principle; an evacuation protection function is further provided; and problems of much labor and time use for culture pond pollution discharging and accidental evacuation can be effectively solved.

Description

technical field [0001] The invention relates to an industrialized closed circulation aquaculture facility, in particular to a method and device for fully automatic timing sewage discharge of a closed circulation water system aquaculture pond. Background technique [0002] The closed circulation aquaculture system is the representative of the current international advanced aquaculture mode, and it is also the main direction of the future development of the aquaculture industry, which has attracted the attention of the world. my country's land-based industrial fish farming started relatively late, with relatively low levels of technical equipment and automation control. After years of development, my country's closed industrial recirculating aquaculture has reached a certain scale. As of 2013, the area of ​​industrial recirculating aquaculture Nearly 400,000 m2, with a rapid development momentum. However, according to the follow-up investigation on the development and operatio...
