Embodiment 2
[0027] Utilize the equipment in embodiment 1 to carry out the cultivation and storage of sewage treatment active flora, concrete steps are as follows:
[0028] a. The equipment for cultivating and storing the sewage treatment active flora described in Example 1 is set.
[0029] b. Put the activated sludge bacteria source into the culture tank 1 through the bacteria source input port 4, and inject the nutrient solution into the culture tank 1 through the nutrient solution supply interface 5 at the same time, and turn on the driving device, so that the bacteria source and the nutrient solution are stirred Mix well under the action of stick 13.
[0030] c. Turn on the selective lighting device 3, and select a matching spectral light source to cast light on the culture tank 1; turn on the aeration device, and control the aeration water-air ratio to be 1:1~3; turn on the electric hot water bath insulation device 10, and control the culture tank 1. The internal temperature is 20~30...

The invention relates to an equipment and method for cultivating and storing active bacterial flora for sewage treatment. The structure of the equipment includes a culture tank, a process control and parameter acquisition device for monitoring process parameters in the culture tank, and a selective illumination device arranged above the culture tank. The device and the aeration device installed at the bottom of the culture tank; the outer side of the culture tank is equipped with an electric hot water bath insulation device, and the top of the culture tank is provided with a bacteria source input port and a nutrient solution supply interface. There is a sewage outlet on one side, and a discharge outlet on the other side of the bottom of the culture tank. The present invention can realize the cultivation of the dominant active flora, the continuation and storage of the activity of the flora, and when the biochemical pool of the sewage treatment system is abnormal, it can replenish the effective flora for it in time, and quickly restore the quantity and quality of the microbial flora in the biochemical pool active.
Description
technical field [0001] The invention relates to equipment and method for cultivating microbial flora for sewage treatment, in particular to equipment and method for cultivating and storing active flora for sewage treatment. Background technique [0002] In the process of organic sewage treatment, the biologically activated sludge method is widely used because of its high effective removal of pollutants. The biologically activated sludge method is based on the type of pollution source to select the applicable dominant bacteria to treat organic sewage. method, which has strong adsorption and oxidation capabilities for organic matter and high treatment efficiency. [0003] Biologically active bacteria exist in the sludge and sewage in the sedimentation tank in the form of spores. It takes a few days or more than ten days for the culture period to transform from the spore form to the dominant activated sludge flora. Because the cultured active flora also has certain Therefore, ...
