Simple circulating water prawn culture pond water processing system

Abstract

The invention relates to a simple circulating water prawn culture pond water processing system characterized by comprising a culture pond and a water processing device. The water processing device is orderly formed by a sediment basin, a particle reverse filter tank, a back water pool and a foam collection pond on one side; a discharging port of the culture pond is communicated with a water inlet of the sediment basin; the particle reverse filter tank is communicated with the bottom of the sediment basin; a reverse sieve plate is installed in the middle of the particle reverse filter tank; a wall of the back water pool close to the sieve plate is provided with a wall-through pipe; one end of the wall-through pipe entering the back water pool is provided with a filter bag; a back water pump and an aeration disc are placed in the back water pool; dirt discharging ports are formed in the bottoms of the sediment basin, the back water pool and the foam collection pond; use area proportion among the sediment basin, the particle reverse filter tank and the back water pool as well as the foam collection pool is 3 to 2 to 4 to 1; and the area proportion of the water processing device and the culture pond ranges from 1to 20 to 1 to 50. The simple circulating water prawn culture pond water processing system is suitable for shrimp; and fish culture and culturing benefits can be improved and culturing water use can be reduced.

Description

technical field [0001] The invention relates to a water treatment system in aquaculture, in particular to a simple circulating water treatment system for shrimp culture ponds. Background technique [0002] my country is a big aquaculture country, and its annual aquaculture production ranks first in the world. Aquaculture has become an important part of my country's fishery. The rapid development of the aquaculture industry has benefited from the improvement of aquaculture technology, such as seedling breeding technology, artificial aeration technology, water quality improvement technology, artificial bait preparation technology, and beneficial microorganism use technology. Especially in recent years, the development of industrialized shrimp farming technology has brought new development direction and driving force for the aquaculture industry. At present, although my country's industrialized shrimp farming is in the initial stage of development, it has shown great potential...

Problems solved by technology

At present, biofloc technology has been widely recognized in industrialized prawn farming. Although the use of biofloc technology to cultivate prawns has many advantages, in the later stage of biofloc culture of prawns, excessive flocs will consume the fish in the culture system. A large amount of oxygen increases the burden of oxygen supply and brings great risks to later breeding

In order to solve the problem of excessive flocs in the later stage of breeding, the technical means used more at present is to increase the amount of water exchange to reduce the concentration of flocs, but this will bring many unfavorable factors, such as reducing the stability of the water environment and increasing the cost of breeding. Heat cost, waste of water resources and flocs, etc.
