The utility model relates to a sewage treatment equipment for environmental protection engineering belongs to sewage treatment technical field, in order to solve the problem that the bubble diameter generated by traditional aeration is usually larger, the rising speed is faster, the oxygen utilization rate is lower, and cannot form the full mixing with sewage, the utility model discloses sewage treatment tank and the oxygen cavity of opening in sewage treatment tank inside, sewage treatment tank both sides are installed with pump body, a plurality of jet elements are fixedly installed in the oxygen cavity, and the pump body is communicated with a plurality of jet elements through the pipeline, and the one end of jet element is installed with suction shell, and the one side of suction shell is communicated with the water outlet pipe, and the rotating part is installed in the water outlet pipe, the utility model discloses through the treatment of jet breaking and rotary shearing, the bubble diameter is significantly reduced, and the specific surface area is greatly increased, and the rising path of bubble is changed by swing plate, prolongs its residence time in sewage, makes oxygen have more sufficient time to dissolve, effectively solves the problem that the oxygen utilization rate of traditional aeration is low.

The application belongs to the technical field of sporogon culture, and particularly relates to a culture method of sporogon of Brychus based on a liquid culture medium, which comprises the following steps: S1, preparing a Brychus sample with mature sporogon; S2, preparing a spore suspension, taking a mature sporangium of the Brychus and taking out spores, and dispersing the spores into distilled water to prepare a spore suspension; and S3, inoculation, inoculating the spore suspension into a culture bottle containing a liquid culture medium, and then culturing the culture bottle after being covered. The application customizes a special liquid culture medium formula according to the physiological characteristics and growth requirements of the sporogon of the Brychus, and matches highly adaptive culture environment parameters, and the two synergistically ensure the smooth culture of the sporogon of the Brychus from the two dimensions of nutrient supply and environment adaptation.

This invention discloses a digital light-processing 3D printing photocurable resin composition, its printing method, and its applications. The digital light-processing 3D printing photocurable resin composition includes a crosslinking agent, a monomer, a chain transfer agent, and a photoacid. By introducing a thioacetal compound as a chain transfer agent, this invention constructs a photoinitiated cationic degenerate chain transfer polymerization system under the action of a photoacid catalyst, achieving active / controllable regulation of the polymerization process. The photocurable resin composition provided by this invention has a simple composition, requires no complex synthetic reagents, and can fundamentally eliminate oxygen inhibition, achieving rapid and high-precision 3D printing with a maximum printing resolution of 57 μm.
