Culture tail water treatment system

Abstract

The invention discloses a culture tail water treatment system which comprises a primary settling zone, an enhanced settling zone, a biological purification zone and an effluent storage zone, the primary settling zone is used for collecting culture tail water discharged from a seawater pond; the enhanced settling zone comprises a reservoir, a water separation dam and filter dams, the reservoir is divided into a plurality of settling ponds which are arranged side by side in the left-right direction by the water separation dam, the settling ponds on the left side are used for collecting culture tail water subjected to preliminary settling, every two adjacent settling ponds are communicated through the corresponding filter dam, and the settling pond on the right side is communicated with the biological purification zone through the corresponding filter dam; the biological purification zone comprises an animal breeding purification pond and a first plant purification wetland, the animal breeding purification pond is communicated with the sedimentation pond located on the right side through a filter dam, and the animal breeding purification pond is communicated with the effluent storage area through the first plant purification wetland. When the culture tail water is treated, the structure and function of the seawater pond are not changed, the process is advanced, the technology is reliable, economical and reasonable, manufacturing cost and operation cost are low, and management and maintenance are convenient.

Description

technical field [0001] The application relates to the technical field of tail water treatment, in particular to a farming tail water treatment system. Background technique [0002] Seawater pond aquaculture is the main aquaculture model in my country's coastal areas. Seawater pond aquaculture is a production method for raising and breeding marine economic animals and plants. It is one of the important ways for human beings to use marine biological resources and develop marine aquaculture. The development of certain fish, shrimp, shellfish, crabs, etc. with high economic value has the advantages of short production cycle and high output per unit area. [0003] However, in the process of aquaculture in seawater ponds, a large amount of tail water needs to be discharged, and these tail waters contain toxic and harmful substances. At present, they are simply discharged through drainage ditches, which can only cause large-scale pollution; and there is a technology The solution is...

Problems solved by technology

[0003] However, in the process of aquaculture in seawater ponds, a large amount of tail water needs to be discharged, and these tail waters contain toxic and harmful substances. At present, they are simply discharged through drainage ditches, which can only cause large-scale pollution; and there is a technology The solution is to use biospheres to purify the tail water of seawater pond culture, but this method can only filter out large particles of impurities in the tail water, and still fails to achieve the purpose of removing pollution
