Controllable laminated aquaculture water treatment device

Abstract

The invention discloses a controllable laminated aquaculture water treatment device and belongs to the field of aquaculture water treatment devices. According to the controllable laminated aquaculturewater treatment device, a laminated filter screen which is controllable in filter degree is formed through a top-layer one-way filter screen, a plurality of middle-layer one-way filter screens and abottom-layer one-way filter screen, on the one hand, the middle-layer one-way filter screens and the bottom-layer one-way filter screen can be properly combined according to the aquaculture water pollution degree, the filter precision of the filter screens can be adjusted to form a required laminated filter screen, and on the other hand, the laminated filter screen formed by the middle-layer one-way filter screens and the bottom-layer one-way filter screen can be separated layer by layer to lose the filter effect by means of detachment, and the middle-layer one-way filter screens and the bottom-layer one-way filter screen, which are arranged in single layer can be cleaned, pollutants accumulated on the surface of the filter screens can be automatically separated under waterflow, and a self-cleaning process is realized, so that the problem that filter plugging is difficult to clean in the prior art can be solved, the dredging state can be restored, and a high efficiency filter process of aquaculture water can be restored.

Description

technical field [0001] The invention relates to the field of aquaculture water treatment devices, and more specifically relates to a controllable stacked aquaculture water treatment device. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. In a broad sense, it can also include the proliferation of aquatic resources. [0003] Aquaculture includes extensive culture, intensive culture and high-density intensive culture. Extensive culture is to put seedlings in small and medium-sized natural waters, and to grow aquatic products completely by natural bait, such as fish culture in lakes and reservoirs and shellfish culture in shallow seas. Intensive farming is the use of bait and fertilization methods to grow aquatic products in smaller water bodies, suc...

Problems solved by technology

[0007] Aiming at the problems existing in the prior art, the object of the present invention is to provide a controllable stacked aquaculture water treatment device, which forms a filter through the top layer one-way filter screen, multiple middle layer one-way filter screens and bottom one-way filter screen. The layered filter with controllable degree, on the one hand, can combine the middle one-way filter and the bottom one-way filter according to the degree of pollution of the aquaculture water, adjust the filtration accuracy of the filter, and form the required laminated filter. On the one hand, by splitting the laminated filter screen combined by the middle lay
