Device for purifying aquaculture waste water

Abstract

The invention discloses a device for purifying aquaculture waste water, which comprises a water culture tank, a water feeding pipeline and a draining pipeline, wherein the water feeding pipeline and the draining pipeline are connected with the water culture tank; the water feeding pipeline is provided with a water pump controlled by a relay; stone filler is put on the bottom of the water culture tank; and the upper part of the water culture tank is provided with a floating bed unit used for culturing economic plants. The device for purifying the aquaculture waste water has the advantages that the purification processing effect on aquaculture waste water is good, the cost is low, the popularization is easy, and certain economic benefit is obtained by the way that the economic plants adsorb nutrient elements, such as nitrogen, phosphorus and the like in the aquaculture waste water.

Description

technical field [0001] The invention relates to the technical field of aquaculture and water treatment, in particular to a device for purifying aquaculture wastewater. Background technique [0002] In recent years, the aquaculture industry has developed rapidly, and the aquaculture model has gradually transitioned from the original extensive farming model to the intensive farming model. Intensive farming is a high-density farming system characterized by high input of artificial bait. Compared with the traditional farming model, intensive farming has the advantages of high output per unit of water body, short breeding cycle, and high labor efficiency. However, in this intensive and high-density farming, the amount of residual bait and excrement exceeds that of microorganisms in the farming pond. The natural decomposition ability of the water often breaks the micro-ecological balance of the water body, resulting in the increase of organic matter, nitrogen, and phosphorus in th...

AI Technical Summary

Problems solved by technology

Although the water environment of aquaculture ponds can be improved by adding microbial agents and chemical water quality treatment agents, the effect is often unstable and unsatisfactory; although the restoration of plants alone saves energy, the efficiency is low, the restoration period is long, and the plants are harmful to the environment. High-concentration wastewater is often unsuitable and cannot be purified; while the industrialized circulating water purification system has high requirements for breeding technology, breeding scale, breeding species and economic strength, etc., it is not easy to promote

[0004] The invention overcomes the shortcomings of high technical requirements for aquaculture wastewater restoration, high difficulty in popularization, and unsatisfactory effects, and proposes an economical plant ecological floating bed technology system, which can degrade organic matter, nitrogen, phosphorus and others produced in the aquaculture process. Pollutants, improve the water quality of aquaculture wastewater, achieve the effect of recycling, and can obtain certain economic benefits
