Description

Circulating type fishery tail water purifying equipment based on photosynthetic microorganisms Technical Field The invention relates to the technical field of treatment of tail water of fishery cultivation, in particular to circulating type fishery tail water purifying equipment based on photosynthetic microorganisms. Background As aquaculture density increases, the environmental pressure from the discharge of aquaculture tail water increases. The biological restoration treatment is carried out on the tail water by utilizing photosynthetic microorganisms, so that nitrogen and phosphorus nutritive salts in the water can be effectively removed, and the chemical oxygen demand can be reduced, thereby becoming an ecological treatment technology with application prospect. However, the existing photosynthetic reaction devices have some defects in the use process. First, photosynthetic microorganism growth metabolism needs to rely on adequate illumination. The light source component is soaked in the water body rich in microorganisms for a long time, and the surface is extremely easy to attach and grow a biological film and accumulate dirt. These attachments block light penetration, resulting in a great decrease in light energy utilization, and thus seriously affecting purification efficiency. The existing equipment generally lacks a high-efficiency automatic cleaning mechanism, and is time-consuming and labor-consuming by simply relying on manual cleaning, and the cleaning frequency is difficult to ensure. Although some equipment is provided with a simple scraping plate, loose dirt on the surface of the equipment can be removed only, and stubborn biological films are difficult to thoroughly remove, and the cleaning driving mechanism is also easy to erode by water impurities to cause mechanical jamming faults. Second, photosynthetic microorganisms need to consume carbon sources and produce oxygen when they perform metabolic reactions. The existing device generally adopts an open structure, oxygen is generated by reaction and unused carbon dioxide is directly dissipated into the atmosphere, so that carbon sources and oxygen sources are wasted. Meanwhile, biological heat energy generated in the reaction process is lost along with the gas, which is unfavorable for maintaining proper reaction temperature. The lack of a gas recycling mechanism also causes poor stirring and mixing effects of the water body and easy occurrence of reaction dead angles. In addition, if the gas is directly recovered, a large amount of water vapor is carried in the gas, and the back-end air pump and the pipeline are easily corroded and damaged. Finally, the mixed solution contains a large amount of suspended bacteria after the reaction is finished. The solid-liquid separation effect of the existing equipment is unstable, micropores of the filtering component are easily blocked by high-concentration bacterial mud, and the water outlet is unsmooth. For collecting the precipitated bacterial sludge, an effective activity protection and reflux mechanism is lacking. The common conveying pump generates strong shearing force in the conveying process, so that the microbial cell wall is easily damaged, the activity of the reflux strain is reduced, the concentration of dominant bacteria in the reaction system is difficult to maintain stable, and simultaneously, the biomass resource waste is caused. Disclosure of Invention Aiming at the defects of the prior art, the invention provides circulating fishery tail water purifying equipment based on photosynthetic microorganisms, which solves the problems that in the existing photosynthetic reaction device, the light utilization rate is reduced due to the fact that a biomembrane is easy to adhere to the surface of a light source component, the effect of a conventional cleaning mode is poor, a carbon source and heat energy are wasted due to the fact that reaction waste gas is directly discharged, a gas recovery system is easy to corrode by moisture, a solid-liquid separation grid is easy to block, and activity is reduced due to the fact that shear force is easy to damage in a strain backflow process. In order to achieve the above purpose, the invention is realized by the following technical scheme: The circulating type fishery tail water purifying device based on photosynthetic microorganisms comprises a photosynthetic reaction treatment box and a biomass collection box, wherein LED light source modules are fixedly connected to the inside of two ends of the photosynthetic reaction treatment box, lamp tube appearance cleaning components are arranged on the inside of the photosynthetic reaction treatment box, waste gas collecting and circulating components are arranged at the top of the photosynthetic reaction treatment box, a plurality of inclined plate type grating plates are fixedly connected to the inside of the biomass collection box, two driving components are arranged on the outer sides of two ends of the b
