Box-type biological floating bed and use method thereof

Abstract

The invention relates to an aquaculture facility, in particular to a box-type biological floating bed. The box-type biological floating bed comprises a rectangular frame (1) formed by pipe fittings. A weaving net (2) is arranged in the frame (1), and thereby an upper floating bed floating on the water surface of a sewage discharge channel is formed; the pipe fittings of the frame (1) of the upper floating bed are millimetric PVC (polyvinyl chloride) pipes; the length-width ratio of the rectangular frame (1) is 1:1.5; the frame can be extended and superposed in the length direction in the proportion of 1; a net cage is weaved by the weaving net below the upper floating bed to form a lower floating bed; and the mesh dimension of the weaving net (2) of the lower floating bed is 0.8-1.5cm. The invention also provides a use method of the box-type biological floating bed, which is characterized in that aquatic plants (3) are planted on the weaving net of the upper floating bed; small filter-feeding fishes (4) are cultured in the net cage of the lower floating bed; and shellfishes (5) are cultured on the bottom of the net cage. The box-type biological floating bed is divided into a water part and an underwater part and can carry out water quality regulation and purification treatment on different water layers; polluted elements can be absorbed by biological species and the water body purification effect is achieved.

Description

technical field The invention relates to aquaculture facilities, in particular to a purification facility for aquaculture sewage discharge channels. Background technique Aquatic organisms have a strong ability to accumulate harmful substances in waters. To ensure the quality of aquatic products, we must start from the source of production—aquaculture waters. With the development of the economy, the ecological environment of the water area has been severely damaged. According to data, more than 70% of the lakes in my country are polluted to varying degrees, about 1 / 3 of the lakes are eutrophic, and more than 3,000 kilometers of rivers Segment fish and shrimp are basically extinct. Facing the serious situation of deteriorating fishery ecological environment, in addition to environmental protection and other departments to strengthen law enforcement and reduce various land-based pollution, marine and fishery departments should first take various effective measures to minimize t...

Problems solved by technology

The river channel pollution is mainly from aquaculture sewage discharge. Therefore, to control the river channel, it is necessary to control and treat the discharge of aquaculture. In addition, traditional aquaculture consumes a lot of water resources. In order to improve the water quality of the river channel, comprehensive utilization To improve the water resources of the river, the present invention proposes a technical solution for the purification treatment of the sewage discharge channel flowing from the aquaculture pond into the river
