Foul drainage system at bottom of pond for culture

Abstract

The invention discloses a foul drainage system at the bottom of a pond for culture. The foul drainage system comprises a pond main body, the bottom of the pond main body slopes in a certain degree, a sewage draining exit is arranged at the lowest part of the bottom of the pond main body, an escape-preventing net is arranged at the sewage draining exit, and the pond main body is communicated with a sewage draining pipe system through the sewage draining exit at the bottom of the pond main body. According to the foul drainage system disclosed by the invention, the current drainage work for pond culture is scientifically designed and distributed, and scientific assembly of comprehensive technologies such as physical cleaning, biological cleaning and the like is implemented, so that the pond can desilt automatically; meanwhile, sludge of the pond does not need to be cleared for 5 to 10 years, a good environment is created for the growth of fish, therefore farmers can implement continuous and healthy culture, the quality safety of aquatic products is guaranteed, and a foundation is built for achieving a prosperous and better-off life through scientific fish farming.

Description

technical field [0001] The invention relates to the fields of integrated innovation and matching assembly of pond development environmental protection, ecological breeding engineering equipment and physical and biological purification technologies, and specifically relates to a pond bottom sewage system that realizes "resource saving and good environment". Background technique [0002] In recent years, in most intensive farming ponds in my country, the aquaculture sediment has exceeded the self-purification capacity of the water body, resulting in eutrophication and endogenous pollution of the aquaculture water. Traditional aquaculture ponds become fish cesspools, draining the upper layer of ponds with high dissolved oxygen, high temperature, and a lot of fish natural bait (plankton). The aquaculture sediment decomposes at the bottom of the pond to consume oxygen, release toxic and harmful substances, pollute the water body, and cause fish diseases Frequent occurrence, low f...

Problems solved by technology

[0002] In recent years, in most intensive farming ponds in my country, the aquaculture sediment has exceeded the self-purification capacity of the water body, resulting in eutrophication and endogenous pollution of the aquaculture water.

Traditional aquaculture ponds become fish cesspools, draining the upper layer of ponds with high dissolved oxygen, high temperature, and a lot of fish natural bait (plankton). The aquaculture sediment decomposes at the bottom of the pond to consume oxygen, release toxic and harmful substances, pollute the water body, and cause fish diseases Frequent occurrence, low feed conversion rate, increased breeding costs

The main reason is that the traditional pond construction lacks environmental protection engineering facilities and equipment, which seriously restricts the continuous production of quality and safe aquatic products of my country's blue land resources.
