System for treating and recycling tail water in aquaculture process

Abstract

The invention discloses a system for treating and recycling tail water in the aquaculture process. The system comprises an aquaculture pool, a sewage pool, a remedying pool, a pebble filter pool, an ecological pool, a water conveying pipe and a water pump, wherein a water inlet and a water outlet are formed in each of the aquaculture pool, the sewage pool, the remedying pool, the pebble filter pool and the ecological pool; the water outlet of the aquaculture pool is connected with the water inlet of the sewage pool; the water outlet of the sewage pool is connected with the water inlet of the remedying pool; the water outlet of the remedying pool is connected with the water inlet of the pebble filter pool; the water outlet of the pebble filter pool is connected with the water inlet of the ecological pool; the water outlet of the ecological pool is connected with the water inlet of the aquaculture pool through the water conveying pipe; the water pump is arranged on the water conveying pipe; water purifying plants are planted in the remedying pool, and a bacillus dispensing device is provided. The tail water produced in the aquaculture pool is treated by the sewage pool, the remedying pool, the pebble filter pool and the ecological pool, and then returns to the aquaculture pool for recycling, so that the recycling of the tail water is achieved.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a tail water treatment and recycling system in the aquaculture process. Background technique [0002] Soft-shelled turtle, commonly known as soft-shelled turtle, turtle and so on. Oviparous amphibian reptiles. Soft-shelled turtle is delicious and has high nutritional value. Because it has many nourishing and medicinal effects, it can clear away heat and nourish yin, calm the liver and relieve wind, soften and harden stagnation, and has curative effects on liver cirrhosis, hepatosplenomegaly, and convulsions in children. Therefore, it is not only a delicacy on the dining table, a high-quality material for a first-class banquet, but also an important traditional Chinese medicine material. [0003] Soft-shelled turtle has been extensively cultured artificially to meet people's needs. Soft-shelled turtles are usually cultured in breeding ponds. During the breeding process, the water qua...

Problems solved by technology

For example: method 1 can reduce the soluble harmful components (ammonia nitrogen, nitroso salt, etc.) At the same time, fish and shellfish themselves also discharge a certain amount of metabolic waste; methods 3 and 4 can remove most of the suspended matter, but cannot reduce the soluble harmful components in the aquaculture water, and the current cost of treating aquaculture water is always too high. High, including device cost, which limits technology promotion
