A tail water treatment device for intensive cultivation of Litopenaeus vannamei in greenhouses

Abstract

The invention discloses a tail water treatment device for intensive culture of Litopenaeus vannamei in greenhouses, aiming to provide a tail water treatment device that can not only make the culture tail water meet the standard discharge, but also provide reference for other breeding enterprises, and at the same time controllable operating costs Tail water treatment device for intensive culture of Litopenaeus greenhouse. It includes a culture pond; a water collection channel, the tail water of the culture pond is discharged into the water collection channel from the head end of the water collection channel; The first water pump is provided on the water lifting pipe; the aeration treatment tank, the aeration treatment tank and the sedimentation treatment tank are connected through the second water lifting pipe, and the second water pump is provided on the second water lifting pipe; the microbial adsorption treatment tank, the microbial adsorption treatment The pool is connected with the aeration treatment pool through the first overflow pipe; the biological wetland treatment pool is connected with the microbial adsorption treatment pool through the second overflow pipe.

Description

technical field [0001] The invention relates to a tail water treatment device, in particular to a tail water treatment device for intensive culture of Litopenaeus vannamei in greenhouses. Background technique [0002] Litopenaeus vannamei (Penaeus vannamei), also known as Litopenaeus vannamei, is naturally distributed along the Pacific coast from Peru to Mexico. Since the introduction of the species by the Institute of Oceanology, Chinese Academy of Sciences in 1988, with the successful breakthroughs in technologies such as seed breeding, breeding mode, nutritional bait, and disease prevention and control, Litopenaeus vannamei farming has grown from Hainan, Guangdong, Guangxi and Fujian provinces in the south of my country. Rapidly develop to Zhejiang and Jiangsu in the central and eastern provinces, as well as Shandong, Hebei and Liaoning in the northern regions. Litopenaeus vannamei has become the most important farmed shrimp species in my country, with an annual output of...

Problems solved by technology

For every ton of shrimp produced, 0.2t of N elements and 0.05t of P elements will be added to the water body. If the tail water of aquaculture cannot be treated in a timely and effective manner, not only will the aquaculture water environment deteriorate, but it will also lead to abnormal reproduction of algae and frequent red tides. Serious pollution of the marine environment

[0003] In recent years, scholars at home and abroad have done a lot of related research on the tail water treatment of aquaculture, but there are few studies on the design examples of the tail water treatment of intensive culture of Litopenaeus vannamei in seawater.
