Water circulation treatment system of outdoor high-level shrimp tank

Abstract

The invention discloses a water circulation treatment system of an outdoor high-level shrimp tank. The system comprises a filter, a protein separator, a denitrification degasser and an oxygen-increasing device. The filter, the protein separator and the denitrification degasser are communicated in turn. Cultivation water in the shrimp tank is subjected to solid-liquid separation, dissolved organicmatter separation and decomposition of poisonous ammoniacal nitrogen compound and nitrous acid compound in turn. The treated cultivation water back flows into the shrimp tank to be used. An aeration part of the oxygen-increasing device is positioned in the shrimp tank so that dissolved oxygen in the cultivation water is increased. The water circulation treatment system further comprises a dissolved oxygen detection pen arranged in the shrimp tank. The dissolved oxygen detection pen is used for transmitting a detected dissolved oxygen numerical value of the cultivation water to an electric control system. The electric control system is used for controlling the oxygen-increasing device according to a comparison result of the dissolved oxygen numerical value and a set value. The water circulation treatment system of the outdoor high-level shrimp tank disclosed by the invention is capable of promoting independent self-purification treatment of water for intraregional shrimp cultivation.

Description

technical field [0001] The invention relates to a water circulation treatment system which is especially suitable for cultivating high-level shrimp in the open air. Background technique [0002] The so-called open-air high-level shrimp pond farming is to dig a pond on the land near the sea, and bring in seawater to raise shrimp. The area of ​​a high-level shrimp pond is generally 5 to 8 mu, the depth of each shrimp pond is about 2.5 to 3 meters, and the water storage is about 2,000 tons. Generally, sewage must be discharged once every time shrimp is harvested. Contains unfinished shrimp feed, shrimp excrement and disinfectants and other dirt and toxins, which are discharged into the sea, which not only leads to eutrophication of seawater, but also endangers plankton in the offshore. According to the characteristics of high-level shrimp pond farming, if the water in the shrimp pond cannot be self-purified, it will not only cause waste of water resources, but also bring pollu...
