Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1-3, a step-type trout recirculating aquaculture system comprises a plurality of fish ponds 1 which are arranged in a step-type manner from high to low in sequence, wherein a fish blocking net 2 is arranged at the rear part of each fish pond 1, a dredging area 3 is formed between each fish blocking net 2 and the rear wall of each fish pond 1, a sludge pipe 4 is arranged at the bottom of each dredging area 3, each fish blocking net 2 can prevent fish from being flushed into the sludge pipe 4 when sludge is cleaned, each sludge pipe 4 is buried underground, the top end of each sludge pipe is slightly higher than the bottom of each dredging area 3, each sludge pipe 4 is sleeved with a plugging pipe 5, each plugging pipe 5 is tightly matched with each sludge pipe 4, and the top end of each plugging pipe 5 is higher than the top of each fish pond 1 so as to prevent water from flowing into each plugging pipe 5; the front end of the first-stage fish pond is connected with a circulating water inlet pipe 6 and a fresh water replenishing pipe 7, the rear end of the last-stage fish pond is provided with a sedimentation pond 8 communicated with the first-stage fish pond, one side of the sedimentation pond 8 is provided with a water pump 9, a water inlet of the water pump 9 is connected with a water pumping pipe 10, the water pumping pipe 10 extends into the upper part of the sedimentation pond 8, a water outlet of the water pump 9 is connected with a water return pipe 11, the water return pipe 11 is communicated with the circulating water inlet pipe 6, the circulating water inlet pipe 6 is provided with a first valve 13, and the fresh water; the bottom of the sedimentation tank 8 is connected with a drain pipe 12, the drain pipe 12 is provided with a third valve 15, and the drain pipe 12 and the sludge pipe 4 are respectively communicated with a farmland irrigation canal or a sludge tank; the water level in the fish pond 1 is flush with the top of the fish pond 1, and the water in the upper-level fish pond continuously overflows to the lower-level fish pond.
During operation, the water in the fish pond 1 constantly overflows to the next level fish pond, can form the waterfall stream (as shown by the arrow in fig. 1) between two-stage fish pond during the overflow, and then increase the chance of contact of water with the air, improve the dissolved oxygen volume, water finally flows into the sedimentation tank 8 and deposits, and the clear water of upper portion flows back to the first level fish pond through drinking-water pipe 10, wet return 11 and circulating water inlet pipe 6 extraction through water pump 9 in the sedimentation tank 8, realizes the bad utilization of circulation of water. When new water needs to be supplemented, the second valve 14 on the new water supplementing pipe 7 is opened to supplement the new water into the fishpond 1, and the first valve 13 arranged on the circulating water inlet pipe 6 can adjust the water inflow of the circulating water.
When the silt of 1 bottom in needs clearance fish pond, extract and cup joint the shutoff pipe 5 on sludge pipe 4, the silt of 1 bottom in fish pond is through rivers erode and see through the sludge pipe 4 that blocks in fish net 2 gets into desilting district 3, and then flows to the farmland irrigation canal or the sludge impoundment that are connected with sludge pipe 4 for provide fertilizer for the farmland, realize ecological cyclic utilization.
