Pond in-situ culture tail water treatment system

Abstract

According to a pond in-situ culture tail water treatment system, a whole pond is divided into a culture pond and a purifying pond, the area ratio of the culture pond to the purifying pond is 7: 3, thewater depth of the purifying pond is at least 1.5 m, and the purifying pond is equally divided into a first purifying pond body, a second purifying pond body and a third purifying pond body; whereina plurality of stem ropes which are arranged in parallel are arranged on the surface of the first purifying pond body, a plurality of floating balls are arranged on the stem ropes, a plurality of breeding net cages are hung in the first purifying pond body, the top ends of the breeding net cages are tied to the stem ropes, and the bottom ends of the breeding net cages droop into the pond bottom and do not make contact with the pond bottom; a plurality of partition plates and microorganism attachment bases are arranged in the second purifyingpond body; a plurality of floating beds are arrangedon the surface of the third purifyingpond body, and hydroponic plants are planted in the floating beds; and culture tail water in the culture pond is purified by the third purifying pond body, the second purifying pond body and the first purifying pond body in sequence and then returns to the culture pond. The treatment system has the advantages of simple facility, high water treatment efficiencyand low energy consumption, and more importantly, the water purifying cycle is uniform and the treatment cost is low.

Description

technical field [0001] The invention relates to the technical field of tail water purification treatment of aquaculture, in particular to a pond in-situ aquaculture tail water treatment system. Background technique [0002] Pond culture is a production method that uses ponds for aquatic economic animals and plants. With the accumulation of the excrement of the breeding objects and the corruption and deterioration of the residual erbium caused by excessive feeding, the water quality in the pond will continue to deteriorate, affecting the healthy growth of the breeding objects. For the sustainable development of pond culture, the water quality control of pond culture is very important. The existing pond culture water quality control technologies mainly include in-situ control and ex-situ treatment. The methods of in-situ regulation mainly include mechanical oxygenation, installing biological floating beds, installing biological brushes, etc., but there are problems of simple...

AI Technical Summary

Problems solved by technology

In-situ regulation methods mainly include mechanical oxygenation, installation of biological floating beds, installation of biological brushes, etc., but there are problems of simple facilities and low efficiency

Ex-situ treatment is to pump the aquaculture water from the pond to specific water treatment equipment for treatment and then transport it to the aquaculture pond. Although the treatment efficiency is improved, it occupies a large area, consumes a lot of energy, and costs high for water purification and treatment.

Moreover, only suction and discharge at a fixed position will cause uneven water purification cycle, which cannot achieve comprehensive purification, which is not conducive to breeding needs
