Description

[Detailed description of the invention] This invention relates to a microorganism monitoring monitor that allows microorganisms in sewage such as activated sludge to remain stationary on a liquid contact window surface and directly and clearly magnify and observe the microorganisms.

Conventionally, in biological treatment of sewage, human waste, etc., for example, when monitoring the state of microorganisms in activated sludge in an aeration tank, it is necessary to sample each time and observe it using a microscope, which requires a great deal of effort.
Furthermore, it was not possible to observe many people at the same time, and continuous observation was difficult.

Therefore, in order to solve the above-mentioned drawbacks, the present applicant installed a television camera with a microscope lens in waste water to develop a microorganism monitor television that can continuously observe enlarged microorganisms and other objects with clear images. The invention was previously filed (utility model registration application filed on June 8, 1982), but the enlarged screen (Utility Model Registration Application No. 85092 of 1988) shows that even the slightest movement of microorganisms, etc. can be extremely large. The movement made it difficult to obtain a clear image.

The purpose of this invention is to eliminate the above-mentioned drawbacks and provide a microorganism monitoring monitor that can directly and clearly magnify microorganisms in wastewater.

An embodiment of this invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, a diaphragm 3, which will be described later, is installed in a waterproof box 2, which is partially or completely immersed in biologically treated wastewater such as sewage and human waste, and which is penetrated by a sample communication slit 1. A drive device 4 and a television camera 5 are arranged.

A monitor television 7 is connected to the television camera 5 through a cord 6, and its lens 8 is a microscope lens, which is located near the liquid surface side of the liquid contact window 9 provided on the sample communication slit 1 side (1). ~
(approximately 1000μ), and a magnified image can be displayed directly on the monitor TV 7.

Further, a diaphragm (sewage stationary member) 3 is disposed at a position opposite to the liquid contact window 9 and in contact with the liquid surface flowing through the sample communication slit 1, and a transparent or translucent light-transmitting member is disposed in the center of the diaphragm 3. Board 1
0 is set. This diaphragm 3 is formed to be slidable in the direction of the liquid contact window 9, and expands and contracts in the direction of the liquid contact window 9 by a drive device 4, and a part of the waste water is transferred between the liquid contact window 9, the spacer 11, and the diaphragm 3. It is designed to be confined in the created space and kept still.

A lighting device 12 is provided behind the transparent plate 10 of the diaphragm 3.

Next, the operation of this invention will be explained. The sewage flows through the sample communication slit 1, and the enlarged microorganisms are directly visualized on the TV monitor 7, but when the microorganisms in the sewage move due to the water flow, they move extremely quickly on the enlarged screen. As a result, a clear screen may not be obtained. However, in this invention, the diaphragm 3 is moved by a drive device 4 controlled by a timer 13 or the like to expand and contract in the direction of the liquid contact window 9 as necessary, and a part of the waste water is trapped in the vicinity of the liquid contact window 9 and kept stationary. So you can always get clear images. At this time, due to the sliding movement of the diaphragm 3, a strong water flow is generated on the surface of the liquid contact window 9, which not only replaces the waste water but also performs the automatic cleaning effect of the liquid contact window 9.
It is possible to effectively prevent dirt from adhering to the surface of the liquid contact window 9. In addition, a lighting device 12 arranged on the diaphragm 3 side
Since bright field illumination of microorganisms and the like can be performed through the transparent plate 10, an extremely clear screen can be obtained.

FIG. 3 shows a second embodiment in which the illumination device 12 is placed on the side of the liquid contact window 9 to provide dark field illumination. In this case, the inner surface of the waterproof box 2 on the TV camera 5 side is To prevent reflected light, it is preferable to paint the rows black or the like. Also, diaphragm 3
The transparent plate 10 is not necessary.

FIG. 4 shows a third embodiment, in which waterproof box 2
A solenoid 14 connected to a lighting device 12 and a timer etc. is provided inside the waterproof box 2, and a support arm is provided at the lower end of the waterproof box 2 to support the Fe plate 15 so as to be able to slide up and down between it and the liquid contact window 9. 16 is attached. During observation, the solenoid 14 is energized and the Fe plate 15 is sucked in the direction of the liquid contact window 9, and a part of the waste water is transferred to the Fe
A clear screen is obtained by trapping microorganisms between the plate 15 and the liquid contact window 9 and keeping them still. At this time, the dirty water on the surface of the liquid contact window 9 is exchanged by the water flow generated by the vertical sliding of the Fe plate 15 due to the intermittent operation of the solenoid 14, and the liquid contact window 9 is automatically cleaned.

FIG. 5 shows a fifth embodiment in which a cylinder 17 is used as the sewage stationary member that slides up and down, and an electromagnetic coil is used as the drive device 4. It operates in the same manner as the above-mentioned embodiment and provides a clear screen. It will be done.
Incidentally, the sewage stationary member is not limited to the above embodiment, and may be a bellows or other expandable member.

As described above, according to this invention, a part of the wastewater is sealed and kept stationary on the surface of the liquid-contact window, which allows for clear magnification observation on a monitor TV, and eliminates the need for sampling each time. There are other effects.
