Method and system for monitoring, preventing and treating pollutants in spirulina culture water body

Abstract

The invention discloses a method and a system for monitoring, preventing and treating pollutants in a spirulina culture water body. The method comprises pollutant monitoring, preventing and treating before culture, during culture and after culture. The system comprises a water mixing tank, a sedimentation tank, a zeolite tank and a disinfection tank. New water and cultivation return water are subjected to large-particle impurity treatment, heavy metal treatment, ammonia nitrogen treatment and disinfection, normal cultivation of the spirulina is ensured, and the problems that due to exogenous pollutants, the spirulina is low in yield, poor in quality, substandard in quality and the like are greatly solved; pollutant monitoring measures are set in the front, middle and rear links of breeding, and the water quality condition is known in time. According to the method, after breeding and harvesting are finished, the breeding water is reused, the residual culture medium in the breeding water can be continuously utilized, only the content of each residual component in the culture medium in the water needs to be sampled and detected when the culture water is used in next breeding, and corresponding components are correspondingly supplemented, so that the breeding cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of spirulina culturing, and particularly relates to a method and system for monitoring and preventing and controlling water pollutants in spirulina culturing. Background technique [0002] After decades of development and promotion of spirulina culture technology in my country, the spirulina culture industry has been developed in many provinces and cities in China. Spirulina culture is mainly divided into several methods such as open water culture, culture pond culture and photoreactor culture. Among them, culture pond culture has the advantages of high breeding density, large output and relatively easy control, and is one of the mainstream breeding methods. The main factors affecting the quality and yield of spirulina are various pollutants, which can be divided into exogenous pollutants and endogenous pollutants according to different sources. Exogenous pollutants such as heavy metals, miscellaneous algae...

AI Technical Summary

Problems solved by technology

Exogenous pollutants such as heavy metals, miscellaneous algae, miscellaneous bacteria, pests, etc. in the aquaculture water, the enrichment characteristics of Spirulina itself will enrich the heavy metals in the aquaculture water, and miscellaneous algae will seize the living space and nutrients of Spirulina , when the impact of bacteria and pests is serious, it will even lead to the extinction of Spirulina. The endogenous pollution is mainly in the breeding process. Due to the high breeding density of Spirulina, if the light and nutrition are insufficient, the amount of dead algae will increase, which not only affects the production but also Affects water quality, and the water harvested from aquaculture can only be sent out as wastewater, which has the problem of waste of resources and increases production costs
