Fish excrement collecting and discharging system

Abstract

The invention provides a fish excrement collecting and discharging system, which comprises an aquatic product culture pond body, a feeding device, an ultraviolet disinfection device, a rotary pollution discharger and a residue excrement collector, a filter, a dirt collecting tank, and a control device; the ultraviolet disinfection device, the rotary pollution discharger and the residue excrement collector are arranged in the middle of the bottom part of the aquatic product culture pond body and orderly connected through a pipeline; the control device is connected with the feeding device, the ultraviolet disinfection device, the rotary pollution discharger and the residue excrement collector; the control device is used for acquiring feeding amount of the feeding device and sediment amount after passing through the filter and comparing the feeding amount with the sediment amount, and controlling the feeding device, the ultraviolet disinfection device, the rotary pollution discharger andthe residue excrement collector according to the comparison result of the feeding amount and the sediment amount. The system can gradually optimize the collection and discharge of the fish excrement and form a whole set of circulating system, namely, save and use water resource while guarantee the growth environment of the aquatic product.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a fish excrement collection and discharge system satisfying high-density aquaculture. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. In a broad sense, it can also include the proliferation of aquatic resources. Aquaculture includes extensive culture, intensive culture and high-density intensive culture. Extensive culture is to put seedlings in small and medium-sized natural waters, and to grow aquatic products completely by natural bait, such as fish culture in lakes and reservoirs and shellfish culture in shallow seas. Intensive farming is the use of bait and fertilization methods to grow aquatic products in smaller water bodies, such as pond fi...

AI Technical Summary

Problems solved by technology

[0003] In high-density intensive breeding, it is necessary to recycle, filter, purify, oxygenate, and sterilize the backwater and sewage in the aquaculture pond for secondary use, which has achieved the purpose of saving water and maintaining the breeding environment. The sewage of the existing aquaculture pond The sewage drainer is an ordinary floor drain with a filter, which cannot be automatically adjusted according to the actual situation, and the secondary water is not easy to recycle and utilize, resulting in a waste of water resources
