Composite three-dimensional aquaculture water environment purification device

Abstract

The invention relates to a composite three-dimensional aquaculture water environment purification device (ecological magic ball). The device comprises a hollow ball and a plurality of carrier filaments. An outside surface of the hollow ball is in a mesh shape; and the hollow ball is provided with a central shaft. The carrier filaments are fixed on the central shaft and extrude towards the surface of the hollow ball in radial pattern. The device provided by the invention can stereoscopically comprehensively evenly stretch and spread in an effective area, so that gas, water and a biological membrane can fully mix, infiltrate, contact and exchange; and the biological membrane uniformly implants on each carrier filament and on surface of the intermediate reticular hollow ball, maintains good activity and gap variability for a long time, gains greater specific surface area during running in water, and can well perform metabolism. The device filaments and the magic ball surface are provided with a nutrition activator, in order to make indigenous microorganisms to form a stable biological membrane faster, and the character of the device has incomparable advantages to other devices.

Description

technical field [0001] The invention relates to a composite three-dimensional aquaculture water environment purification device, belonging to an ecological process system for effective ecological restoration and regulation of the aquaculture water environment. Background technique [0002] In recent years, the scale of aquaculture intensification has become larger and larger, resulting in more and more serious water environment problems for aquaculture, which has become a technical bottleneck restricting the aquaculture industry. In traditional aquaculture technology management, microbial preparations are often used to expand the flora. However, due to complex water environment changes, microbial preparations cultivated under such laboratory conditions die quickly due to inadaptability to the environment, causing farmers to spend a few days. It is not possible to directly change the water once a day, which undoubtedly increases the cost of breeding. At the same time, the dis...

Problems solved by technology

In traditional aquaculture technology management, microbial preparations are often used to expand the flora. However, due to complex water environment changes, microbial preparations cultivated under such laboratory conditions die quickly due to inadaptability to the environment, causing farmers to spend a few days. Putting it in once a day, it is impossible to change the water directly, which undoubtedly increases the cost of breeding. At the same time, the discharge of wastewater has a serious impact on the surrounding environment and has become one of the important culprits of rural non-point source pollution.
