Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] see Figure 1-Figure 3 :

[0033] 1) The combined sedimentation facility 1 is divided into three cavities by the first and second inner partitions 11a, 11b. The top elevation of each cavity is the same as that of the culture tank, and the bottom elevation is the same, and the bottom of each cavity is equipped with a drain . The anterior cavity is communicated with the culture pond through the connecting pipe 12, the upper end of the connecting pipe is inserted into the movable standpipe 13, and the lower end is connected to the plug 14. The length of the moving standpipe is determined according to the required water level in the culture pond; the middle cavity is divided into two layers, the upper layer is the filter material layer, and the lower layer is the water distribution structure layer. The filter material layer is composed of...

Abstract

The invention relates to a culturing recycled-water treatment system. The system comprises a combined precipitation facility, a three-phase internally circulating fluidized bed and an ozone purification device, wherein the inside of the combined precipitation facility is separated into three cavities by a first internal separator and a second internal separator; the front cavity is communicated with a culture pond by virtue of a connecting pipeline, a movable vertical pipe is inserted to the upper end of the connecting pipeline, the lower end of the connecting pipeline is connected with a plug, and the plug is subjected to first-step precipitation; culturing water spilled from the upper end of the movable vertical pipe is freely settled in the front cavity, and the front cavity is subjected to second-step precipitation; the bottom of the front cavity is communicated with the intermediate cavity by virtue of a water distribution pipe, the intermediate cavity is separated into an upper filter material layer and a lower water distribution structure layer, and the intermediate cavity is subjected to third-step precipitation; the rear cavity is subjected to primary water lifting by virtue of a submersible pump, and the water respectively enters the three-phase internally circulating fluidized bed and the ozone purification device; a draft tube is arranged in the three-phase internally circulating fluidized bed, and an air distribution uniform pipeline component is arranged under the draft tube; a cylindrical tank body is filled with a filter material; pure water drained from the liquid outlet flows back to the culture pond; and the pure water drained from the ozone purification device flows back to the culture pond.

Description

technical field [0001] The invention relates to a breeding circulating water treatment system and a process method thereof, belonging to the technical field of breeding circulating water treatment. Background technique [0002] The industrialized recirculating aquaculture characterized by water recycling is the most advanced production method for the industrialized development of aquaculture. Compared with traditional aquaculture methods, it has the characteristics of not being restricted by the external environment, saving water, saving land, high-density intensification, controllable production, and zero discharge of pollutants. It is an inevitable trend in the transformation of aquaculture methods. [0003] The technical key of industrial recirculating aquaculture production mode is the recirculating water treatment system. A typical circulating water treatment system is an integrated system based on a physical purification device for removing suspended solids combined w...
