Sewage discharging system of fish aquaculture pond

Abstract

The invention discloses a swage discharging system of a fish aquaculture pond. The swage discharging system of the fish aquaculture pond comprises a bait table, a sewage collection groove, a swage suction system composed of an immersible pump and a water delivery pipe, a water delivery square groove and a swage settlement pond arranged at the geng (a low bank of earth between fields) of the aquaculture pond; the bait table is a long-strip shaped platform, the bait table extends into the pond, and the far off-bank end of the bait table is provided with a bait feeding machine; the sewage collection groove is located right ahead of the bait table, the lower portion of the sewage collection groove is embedded into the bottom of the pond, the immersible pump is installed in the sewage collection groove, an outlet of the immersible pump is connected with a water delivery pipe, a water outlet of the water delivery pipe extends into the water delivery square groove, a water outlet of the water delivery square groove is connected with a water inlet of the swage settlement pond, the swage settlement pond is provided with an upper lid, the upper portion of the swage settlement pond is provided with a clear water overflow opening, the bottom end of the swage settlement pond is provided with a clean pond sewage draining hole, and a swage draining pipe is arranged in the clean pond sewage draining hole. According to the swage discharging system of the fish aquaculture pond, redundant bait residue and most fish excreta in the pond can be absorbed, and eutrophication in the pond is obviously alleviated; meanwhile, the sewage discharging system is low in production cost, and has high application and popularization value.

Description

Technical field [0001] The invention relates to a fish breeding pond sewage system, in particular to a fish breeding pond residual bait, fish manure and other sewage collection and treatment related facilities. Background technique [0002] my country’s fish farming area has ranked first in the world for many years. The relevant data ("2015 National Fishery Economic Statistics Bulletin") shows that the national aquaculture area in 2015 was 8465K hm 2 , Of which, the marine aquaculture area is 2317.76K hm 2 , Freshwater aquaculture area 6147.24K hm 2 , The area ratio of mariculture to freshwater aquaculture is 27:73. The area of ​​fish farming ponds varies, and the size is less than 1hm 2 , The larger one is more than 100hm 2 . The fishery ponds in the coastal areas of Jiangsu are mostly 6hm 2 -30hm 2 Among them, it is suitable for large-scale and facility cultivation of marine and freshwater aquatic products. [0003] In recent years, with the rapid development of the aquaculture ...

Problems solved by technology

Therefore, most of the feed residues and fish feces in the pond will remain around the bait table, forming the main dirt concentration area for pond farming, causing water pollution, affecting the fish load in the pond and the quality of the cultured species
