The topic of this issue: Activated Sludge Method, Water Treatment Process, Indicating Microorganisms: Oblique TubeWorm.
Today Zhang Gong continues to share with you about the "supporting roles" in the activated sludge method water treatment, although these microorganisms are not directly involved in water purification, but it is precisely because of their existence that we can indirectly judge the status of the entire system, do precautions, and eliminate the upcoming problems and hidden dangers in advance, so although they are "supporting roles", to some extent, they are also indispensable "protagonists"!
So let's take a look at this one today: the oblique tube worm, to understand its insect body characteristics and corresponding indications. Video address Please move to Zhang Gong Matrix Number: Miao Zhi Water Circle To watch, watch address: Environmental Protection Water Treatment Tips: Non-activated Sludge Indicates Microorganisms Oblique Tube Worm, Environmental Engineering Collection
If it's not convenient for you to watch the video, you can use the following brief text explanation to see what there is about the oblique tube worm.
▲ Comic image of the oblique tube worm
The body of the oblique tube worm is between 50 and 100 microns long, ovate in shape, with a pointed protrusion on the top side of the head, and the central part of the body is observed laterally. There is a pharynx in the center of the worm body near the head, and the cell mouth is open to the surface of the body. Usually rely on the cell mouth close to the floc to slide and move.
▲ Live inclinated tubeworm under the microscope
Oblique tubeworm often appears in the middle of the period of good treatment of activated sludge, and can generally be observed when organic matter remains in good condition in the treated water. Most can be observed simultaneously with small amoeba, tail filaria and bagworms. Overall, intrachomatodes are less tolerant of low dissolved oxygen environments.
Well, about today's sharing, we will say here, small partners can leave a message in the message area, Zhang Gong will reply to everyone in the first time, so that we can improve everyone's technical level as quickly as possible!
