Description

Technical Field

[0001] The invention belongs to the technical field of aquaculture, and in particular relates to an aquaculture sewage treatment device. Background Art

[0002] my country is the world's largest aquaculture country, and its aquaculture output accounts for 70% of the world's total. The aquaculture density is generally high, resulting in a large amount of feces, leftover bait and other particulate matter deposited at the bottom of the pond, causing the pond water to deteriorate and reducing the survival rate and growth rate. Therefore, in order to maintain good water quality, a sewage discharge device is needed to discharge the particulate matter deposited at the bottom of the aquaculture pond. Most of the existing sewage discharge devices for aquaculture directly extract the particulate matter, mud and water at the bottom of the aquaculture pond, and discharge them out of the pond together, and then add clean water to the aquaculture pond, which greatly increases the water consumption, not only wastes water resources, but also increases production costs. In addition, most of the existing sewage discharge devices for aquaculture ponds use mud pumps to enter the pond for artificial sewage discharge, and the sewage discharge efficiency is very low, which also poses a certain threat to the personal safety of fishermen. At the same time, the existing sewage discharge devices for aquaculture ponds cannot effectively utilize clean energy and cannot achieve energy conservation and environmental protection. Summary of the invention

[0003] The purpose of the present invention is to propose a reasonable, applicable, easy-to-operate and reliable discharge device for aquaculture residual bait excrement, circulating water, dead fish, dead shrimp and shrimp shells in view of the problems existing in the prior art and the current status of aquaculture at home and abroad. It is a discharge device for treating residual bait excrement, circulating water, dead fish, dead shrimp and shrimp shells in aquaculture, which can effectively discharge the residual bait excrement concentrated at the bottom of the breeding pond in a timely manner, reduce or avoid the pollution of the breeding water body by the residual bait excrement and the diseases caused by the pollution, and discharge the breeding circulating water and residual bait excrement separately, which is convenient for effective treatment respectively. Dead fish, dead shrimp and shrimp shells are extracted in time, which effectively reduces water pollution, improves the breeding water quality, reduces energy consumption, and improves production efficiency and benefits.
