Abstract

The invention discloses a method for cultivating chrysophyceae by utilizing cynoglossus semilaevis cultivation waste water, including the steps of cynoglossus semilaevis cultivation waste water precipitation or filtration, mixed culture solution preparation and isochrysis zhanjiangensis cultivation. The invention adopts culture solution taking cynoglossus semilaevis cultivation waste water as main body, thus greatly reducing cultivation cost, and cultivation waste water purification is realized and carbon emission is reduced while the microalgae is obtained. Besides, cultivation water quality is improved while isochrysis zhanjiangensis with higher economic value is obtained, and the invention has better economic and social benefits.

Description

technical field [0001] The invention relates to a technique for cultivating golden algae by using aquaculture wastewater, in particular to a method for cultivating golden algae by using the wastewater of tongue sole aquaculture. Background technique [0002] Aquaculture wastewater is rich in nutrients such as nitrogen and phosphorus and organic matter. Its excessive discharge is an important factor causing eutrophication of water bodies and environmental pollution of surrounding waters. Although many treatments for aquaculture wastewater have been developed technology and equipment, but because the relevant technology is not perfect and mature enough, as well as high operating costs and energy consumption, the actual application effect is not ideal. [0003] Isochrysis zhan jiangensis (Isochrysis zhan jiangensis) is an important and widely used marine unicellular algae, and it is a high-quality bait for bivalve molluscs and sea cucumber larvae. Therefore, the cultivation of...
