Abstract
Description
Technical Field
[0001] This utility model relates to the field of reclaimed water treatment technology, and specifically to a reclaimed water treatment device. Background Technology
[0002] Aquaculture wastewater contains a large amount of organic pollutants. Upon entering water bodies, it severely impacts water quality, first causing turbidity, turning the water yellow, and imparting a foul odor. The wastewater also contains significant amounts of nitrogen and phosphorus pollutants. Most nitrogen compounds are oxidized into nitrates, some of which remain in the topsoil, while others seep into the ground, accumulating over time and polluting groundwater sources. Excessive phosphorus in wastewater flowing into rivers, ditches, and ponds leads to eutrophication, causing algae and other plankton to proliferate uncontrollably, reducing dissolved oxygen levels and producing various toxins, directly affecting the growth of aquatic plants and animals.
