Water quality circulation purification and oxygen supply for aquaculture ponds

摘要

PROBLEM TO BE SOLVED: To provide a water quality circulating purification and oxygen supply device for an aquaculture pond, which has a high purification rate for aquaculture wastewater, a high oxygen content, realizes recycling of water resources, and reduces water pollution. A drainage device connected to an aquaculture pond via a water pump, a filter connected to the drainage device, and a membrane separation purification mechanism connected to the filter and used for deep purification of wastewater. The membrane separation and purification mechanism is composed of multiple membrane purification modules connected in series, and after being processed by the membrane purification module, the wastewater flows into the circulating water tank, then enters the filter and circulates, and the membrane purification module After being treated in, the purified water is sterilized and disinfected by the UV module, flows into the blast aeration mechanism, and returns to the aquaculture pond.
