Abstract

The present invention relates to photosynthetic bacteria curing particles and a preparation method thereof, and belongs to the technical field of environmental protection. In the prior art, the preparation process for the photosynthetic bacteria curing particles has the disadvantage of long time consumption, the concentration degree of the prepared photosynthetic bacteria curing particles is not sufficient, the adhesion of the photosynthetic bacteria curing particles is not good, the bacteria loss during the sedimentation process is large, the divergence area after pouring in the water is small, and the purification effect is not good. The purpose of the present invention is to solve the technical problems in the prior art. The technical scheme of the present invention is to provide the photosynthetic bacteria curing particles, which comprise the following components, wherein the components comprise, by weight, 900-1000 parts of diatomite, 30-50 parts of bentonite and 1000 parts of a photosynthetic bacteria liquid.

Description

technical field [0001] The invention relates to photosynthetic bacteria solidified particles and a preparation method thereof, belonging to the technical field of environmental protection. Background technique [0002] Photosynthetic bacteria (Photosynthetic bacteria, PSB) are a class of microorganisms that use light as energy and can use organic matter, sulfide, ammonia, etc. in nature as hydrogen donors and carbon sources to perform photosynthesis under anaerobic light or aerobic dark conditions. . According to the "Berger's Bacteria Identification Manual" (8th Edition, 1974), the photosynthetic bacteria that do not produce oxygen and photosynthesis are listed as Rhodospirillales (Rhodospirillales) of the bacterial phylum Eubacteria, and the bacterial phylum Rhodospirillales are under Divided into Rhodospirillineae (Rhodospirillineae) and Chlorobiineae (Chlorobiineae). (Chlorobiaceae) and green filamentous bacteria (Chloroflexaceae) a total of 18 genera, about 45 species...
