Immobilized microorganism water quality improving device

Technical Field

Background

In recent years, the aquaculture industry in China is rapidly developed, and in the aquaculture process, as a large amount of exogenous pollutants such as COD (chemical oxygen demand), ammonia nitrogen and the like are accumulated, aquatic organisms, particularly algae are massively propagated, the eutrophication of a water body is caused, and the survival of the cultured organisms is greatly influenced.

Sewage treatment is a process of purifying sewage to meet the water quality requirement of discharging the sewage into a certain water body or reusing the sewage. Different from common sewage treatment, COD and ammonia nitrogen in aquaculture water are far from being treated by means of the self-purification capacity of the water, and the pollution problem of the aquaculture water cannot be fundamentally solved by means of physical remediation technology, chemical remediation technology and the like, and the residue of chemical agents can cause environmental damage to a pond. Therefore, more and more research is being directed towards microbial communities and some aeration devices.

In recent years, the application of the microbial water quality improver to the domestic polluted water quality improvement field is gradually developed. At present, the mainstream technology adopts the method of directly adding a microorganism water quality modifier into water, and microorganisms exist in a water body in a free state. But adverse reasons such as environmental factors and easy loss can cause the loss of free microorganisms, and the application cost of the microorganism product is increased. Therefore, the immobilized microorganism technology has received high attention from researchers. However, the direct input of immobilized microorganism particles into water body has the problems that the immobilized microorganism particles are not easy to recycle, the microorganism is difficult to form a stable biomembrane and cannot be rapidly proliferated, the slow release capability of the immobilized microorganism is reduced, so that the water body treatment while culture is difficult to achieve, the treatment cost is increased, and the like.
