Problems solved by technology

The use of microalgae to treat sewage has good development prospects and advantages, but factors such as high concentration of ammonia nitrogen and low transparency in sewage are not conducive to the growth of microalgae, and it is often difficult to achieve the desired effect by using a single microalgae to treat sewage; therefore, the development of a High-efficiency algae preparations are particularly important for treating high-concentration ammonia nitrogen sewage

Abstract

The invention belongs to the technical field of algae, and discloses an immobilized compound algae microsphere, which is prepared according to the following process: step 1) preparing a concentrated liquid of Crescent algae, step 2) preparing a concentrated liquid of Scenedesmus obliquus, and step 3 ) preparing the concentrated solution of Fusarium algae, step 4) preparing algae microspheres. The immobilized composite algae microsphere of the present invention can be applied to the treatment of high ammonia nitrogen sewage through the synergistic effect of various algae.

Description

technical field [0001] The invention belongs to the technical field of algae, in particular to an immobilized compound algae microsphere and its application. Background technique [0002] Fusarium cellulophyta belongs to the phylum Chlorophyta, unicellular, or clusters of 4, 8, 16 or more cells, often sticking to each other at the slightly protruding part of the middle of the cell, and their long axes are parallel to each other. Fascicle-like, sometimes slightly curved and arched or sickle-shaped, gradually tapering from the middle to both ends, chromatophore flake, 1, with 1 protein nucleus. The cells are 20-80 microns long and 1.5-4 microns wide. They are planktonic species that grow in puddles, ponds, lakes, and reservoirs. They are distributed in Guizhou, Yunnan, Jiangxi, Fujian, Zhejiang and other places, and are widely distributed at home and abroad. Small crescent algae, Dinosaceae, Crescent genus, distributed in Zhejiang, Jiangsu, Anhui. Unicellular, crescent-shape...
