Fixing assembly based on riverway remediation microorganism culture dish

Abstract

The invention relates to the technical field of riverway remediation microorganisms, and discloses a fixing assembly based on a riverway remediation microorganism culture dish. The fixing assembly comprises a shell; a support plate is fixedly connected to the left side of the upper end of the shell; a fixing shaft is fixedly connected to the front end of the support plate; a cover plate is movablyarranged on the outer side of the fixing shaft in a sleeving mode; a circular groove is formed in the upper end of the shell; a culture bottle is movably inserted into the circular groove; and a positioning groove is formed in the lower end wall of the culture bottle. A riverway microorganism sample is put into the culture bottle, an adjusting rod continues to be rotated in the reverse directionto adjust the culture bottle to be horizontal, then a lifting rod is rotated in the reverse direction to reset the culture bottle into the circular groove, the cover plate seals the culture bottle tightly, a control rod is rotated, and the control rod moves leftwards under the tangential force of outer side threads and a second circular hole; and the control rod pushes a push plate to move leftwards, and the push plate drives a pressing plate to move leftwards through a movable rod, so that the pressing plate pre-tightens the culture bottle, and the effects of firm fixation and high sewage treatment efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of river restoration microorganisms, in particular to a fixing assembly based on a river restoration microorganism petri dish. Background technique [0002] River channel microbial cleaning technology is a technology for treating black and odorous water in river channels by using microorganisms with short cultivation period, fast reproduction speed, strong adaptability and high conversion efficiency. Since the river channel microbial cleaning technology can effectively clean up organic matter, nitrogen Phosphorus and phosphorus can inhibit the growth of algae, so it has been widely studied and applied, and the petri dish and medium are the basis of the river microbial restoration experiment, which directly affect the results of the microbial restoration experiment. In the river microbial restoration experiment, it is often necessary to prepare A large number of plate media are used for the separation, cultiv...
