Embodiment 1

[0034] The preparation method of the composite photosynthetic bacteria preparation used in sewage treatment adopts the sulfur bacteria species of sulfur tartamen in the purple sulfur photosynthetic bacteria and the rhodopseudomonas palustris in the purple non-sulfur photosynthetic bacteria to cultivate according to the following steps:

[0035] 1. Activation and cultivation of the semi-solid seeds of Thiobacillus tarotrichum: puncture the species of Thiobacillus tarotrichum in the semi-solid medium of Thiobacillus tarotrichum, and culture it under light at 30°C for 8 days, and the bacterium thread to be punctured turns red and grows a lawn, that is It may be an activated Sulfur pericum species;

[0036] 1. Plate activation of Rhodopseudomonas palustris: Streak and activate Rhodopseudomonas palustris strains on the plate, activate and cultivate at 30°C for 4 days, and pick large colonies as activated seeds;

[0037] . Seed culture of Sulfur persicum: inoculate the activat...

Abstract

The invention provides a composite photosynthetic bacteria preparation which is applied to sewage treatment and can quickly degrade sulfuretted hydrogen, ammoniacal nitrogen and COD (chemical oxygen demand) as well as a preparation method of the composite photosynthetic bacteria preparation. A thiocapsa roseopersicina strain in purple sulfur photosynthetic bacteria and a rhodopseudomonas palustris strain in purple non-sulfur photosynthetic bacteria are adopted to obtain thiocapsa roseopersicina and rhodopseudomonas palustris photosynthetic bacteria preparation with high concentration after composite seed activation culture, seed culture, anaerobic fermentor light culture and other culture steps. The composite photosynthetic bacteria preparation can quickly and efficiently degrade sulfuretted hydrogen, ammoniacal nitrogen and COD in a water body during sewage treatment. The invention provides a preparation method of the composite photosynthetic bacteria preparation which is obtained by mixed culturing of thiocapsa roseopersicina and rhodopseudomonas palustris and can quickly and efficiently degrade sulfuretted hydrogen, ammoniacal nitrogen and COD in sewage, the growth speed is high, the thallus content is high, and the culture time is short.

Description

technical field [0001] The invention belongs to the technical scope of sewage treatment, and in particular relates to a composite photosynthetic bacteria preparation capable of rapidly degrading hydrogen sulfide, ammoniacal nitrogen and COD in sewage treatment and a preparation method thereof. Background technique [0002] With the continuous development of urbanization, municipal treatment facilities such as sewage treatment plants, sewage lifting stations, garbage transfer stations, and landfills are getting closer and closer to people's living areas. The foul-smelling exhaust gas generated by these facilities during operation It has become an important factor affecting people's normal life. The malodorous exhaust gas mainly includes sulfur-containing compounds (hydrogen sulfide, methyl mercaptan, methyl sulfide, etc.), nitrogen-containing compounds (ammonia, etc.) and compounds composed of carbon, hydrogen or carbon, oxygen, and oxygen (fatty acids, etc.). It has the cha...
