Abstract

The invention discloses a biological membrane culture system in saline-alkaline water fish aquiculture, belongs to the technical field of water treatment, and aims to solve the problems that a biological membrane in an existing culture device is long in membrane forming time and easy to damage. The biological membrane culture system comprises a fixed biological bed culture pond and a movable biological bed culture pond, an annular water outlet pipeline and an annular back flushing pipe are arranged in the fixed biological bed culture pond, an overflow pipe is vertically arranged at the center of the pond bottom, a pipe port in the top of the overflow pipe serves as an overflow port and higher than a stainless steel mesh arranged on the pond surface, a first annular water spraying pipeline and a second annular water spraying pipeline are arranged in the movable biological bed culture pond, a water outlet is formed in the center of the pond bottom, and an overflow cover covers the water outlet. According to the culture system, biological membranes on floating filter material carriers are continually stimulated by water flow, biological membrane culture is accelerated, the adhesion quality of the biological membranes is improved, and firmness of the biological membranes can resist impact of water pressure ranging from 0.5MPa to 0.7MPa.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a biofilm cultivation device. Background technique [0002] At present, the problems that our country is facing are the lack of water resources, uneven regional distribution, increasing land salinization, a large amount of saline-alkali water and soil resources that are suitable for fishing have been in a state of waste for a long time, and there is a lack of good water that can be directly used by people. Saline-alkaline water that cannot be used directly. As fishery occupies an increasingly important position in my country's agricultural development, the available resources for fishery production are shrinking, and the social demand for aquatic products is increasing. The development of water resource fishery, the development of new fields of saline-alkali fishery production, to solve the problem of using part of saline-alkali water, rational and effective u...
