Culture tail water treatment system based on ecological ditch water purification principle

Abstract

The invention relates to the technical field of water treatment. The invention provides a culture tail water treatment system based on an ecological ditch water purification principle. The system comprises an ecological ditch, the ecological ditch comprises a settling zone, an aeration zone, a purification zone and a check gate, and a biological floating bed and a biological filtering brush are arranged in each of the settling zone and the purification zone; the inlet of the aeration zone is communicated with the outlet of the sedimentation zone through a first ditch; the outlet of the aeration zone is communicated with the inlet of the purification zone through a second ditch, the inlet of the check gate is communicated with the outlet of the purification zone through a third ditch, and filter dams are arranged on the first ditch, the second ditch and the third ditch. According to the culture tail water treatment system based on the ecological ditch water purification principle, breeding tail water can be effectively treated, and healthy aquaculture and environmental protection are achieved.

Description

Technical field [0001] The invention relates to the technical field of water treatment, in particular to a breeding tail water treatment system based on the principle of ecological ditch water purification. Background technique [0002] After a period of aquaculture, there will be a lot of pollutants in the tail water of aquaculture. These pollutants mainly include three categories: the first category is suspended solids, the second category is organic pollutants, and the third category is inorganic nutrients N and P. If these aquaculture tail waters are not treated in a timely and effective manner, it will not only worsen the aquaculture environment, cause diseases of fish, shrimp, crab and other farmed animals, but also reduce the quality and output of aquaculture products. [0003] Many of the existing aquaculture tail water treatment systems use physical and chemical methods to treat the aquaculture tail water, but the aquaculture tail water treated by the physical and chemical...

AI Technical Summary

Problems solved by technology

If these aquaculture tailwaters are not treated in a timely and effective manner, it will not only deteriorate the aquaculture environment, cause diseases of fish, shrimp, crabs and other aquaculture animals, but also reduce the quality and output of aquaculture products.

[0003] Many of the existing aquaculture tail water treatment systems use physical and chemical methods to treat the aquaculture tail water, but the aquaculture tail water treated by physical and chemical methods is discharged into the outside world, which will have a certain negative impact on the natural environment
