Mariculture tail water purification device

Abstract

The invention discloses a mariculture tail water purification device, and relates to the technical field of mariculture. The mariculture tail water purification device comprises a first purification device, a second purification device and a neutralization device, the second purification device is arranged on one side of the first purification device, and the neutralization device is arranged on the side, away from the first purification device, of the second purification device. A second connecting water pipe is fixedly connected between the outer walls of the first purifying device and the second purifying device, and a third connecting water pipe is fixedly connected between the outer walls of the second purifying device and the neutralizing device. Through cooperative use of multiple stages of purification devices, multiple times of purification operation on aquaculture tail water is achieved, and the purification effect is better; the tail water is primarily purified through the first purification box, and suspended large-particle garbage can be conveniently collected and treated; and through cooperative use of a backwashing water inlet pipe, a spray pipe and other devices, the second filter screen can be conveniently washed and cleaned.

Description

technical field [0001] The invention relates to the technical field of mariculture, in particular to a device for purifying tail water of mariculture. Background technique [0002] Seawater pond aquaculture is the main aquaculture model in coastal areas of my country. 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. Some fish, shrimp, shellfish, crabs, etc. with high economic value have the advantages of short production cycle and high output per unit area. 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, which need to be purified. For example, the Chinese patent whose patent number is CN111115915B discloses a kind of purification treatment equipment for mariculture wastewater, whi...

[0005] 2. Through a number of connecting springs, the seawater primary filter screen is driven to vibrate on the seawater filter box, and the impurities in the mesh of the seawater primary filter screen are filtered. Long-term vibration cleaning, although the purpose of cleaning can be achieved, However, it is easy to damage the filter screen, shorten the service life of the filter screen, and the cleaning effect is not good;
