この発明は、水処理、純水製造などの水質管理
用の濁度測定装置にかんする。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a turbidity measuring device for water quality control such as water treatment and pure water production.
低濁度の水質を要求される工業用水、膜法によ
る脱塩装置への給液の水質管理は、工業用水試験
方法JISK0101の５乃至７頁に記載されている光
透過法の測定限界以下の濁度が要求されている。 For industrial water that requires low turbidity water quality, water quality control for water supplied to desalination equipment using the membrane method is to ensure that the water quality is below the measurement limit of the light transmission method described on pages 5 to 7 of the industrial water test method JISK0101. Turbidity is required.
このため逆浸透装置への給液の濁度測定には、
光透過法を使用することができず、精密過膜の
目塞りを利用した過法による測定方法が広く利

空気圧力タンク、直径47mmの精密過膜およびそ
れを取付ける過器からなる装定器を使用し、圧
力2.1Kg／cm2Ｇの下で四定量過する時間を測定
し、つぎの式によつて濁度FI値を求めている。 Therefore, when measuring the turbidity of the liquid supplied to the reverse osmosis device,
Since it is not possible to use a light transmission method, a measurement method based on a transmission method that utilizes the clogging of a precision membrane is widely used. An example of this turbidity measurement method is to use a device consisting of an air pressure tank, a precision filtration membrane with a diameter of 47 mm, and a filtration device to which it is attached. The turbidity FI value is calculated using the following formula.
ここでt1：最初の500mlの過時間
t2：Ｔ時間（通常15分）後の500mlの過逆浸
透装置へのFI値は３以下が要求されており、こ

よいが、廃水、かん水のように濁度の変動が著じ
るしい場合、また前処理設備の運転状態の変化に
よる濁度の急増などが予想される場合は逆浸透装
置の運転にトラブルを生じるため運転を停止せね
ばならない。 Here, t 1 : Elapsed time for the first 500 ml t 2 : After T time (usually 15 minutes), the FI value of 500 ml into the reverse osmosis device is required to be 3 or less, and the stock solution should be adjusted to meet this index. Pretreatment is fine if the raw solution is seawater where the turbidity changes over time, but if the turbidity changes significantly like wastewater or brine, or if the operating status of the pretreatment equipment is If a sudden increase in turbidity is expected due to changes, trouble will occur in the operation of the reverse osmosis device, and the operation must be stopped.

浄が手作業であり精度が低下するなどの欠点があ
つた。 Therefore, an attempt has been made to use a tape-like membrane as a membrane and sequentially feed the tape to perform the same operations as the conventional method, but this method has a yield of 2.1Kg/cm 2
G is carried out under constant pressure, resulting in delays in separating the measurement liquid from the process line and putting it into the constant pressure tank
Difficulty measuring 500ml with high precision;
Disadvantages include the large number of liquid supply and drain valves, and the manual cleaning of the filter and piping, which reduces accuracy.

A buffer chamber 23 is provided downstream of the metering pump 3, and a pressure gauge 22 (pressure transmitter) is connected thereto. Further, the branch pipe 2 is branched into a cleaning water pipe 5 on the liquid supply cell 7 side, and the cleaning liquid is introduced into the liquid supply cell by switching valves 4 and 6.
The overcell 9 is cylindrical like the liquid supply cell 7, and by being placed on the liquid supply cell 7, both cells form a cylindrical overcontainer 24. A paper support plate 10 is attached to the bottom of the overcell 9. This support plate 1
0 is preferably a glass pass plate. An O-ring 8 is fitted around the inner edge of the liquid supply cell 7,
When the overcell 9 and the liquid supply cell 7 come into pressure contact, a liquid-tight function is exhibited. The vertical movement of the overcell 9 is performed by a combination of an air cylinder 21 and a compressor 19.
The overcell 9 is provided with a liquid pipe 11 communicating with its inner chamber. A paper 16 is held between the overcell 9 and the liquid supply cell 7.
One end of the paper 16 is wound around a paper cartridge 15 and the other end is wound around a take-up roll 17. paper 1
The feeding of 6 is performed by rollers 18. A cleaning drainage liquid receiving tray 13 is provided around the overcell 9, and a cleaning drainage liquid outlet 14 is connected to the bottom thereof.

る。 When measuring turbidity, the liquid supply cell 7 and the overcell 9 squeeze the paper 16, and the overcell 9 is pushed down by the air pressure of the air cylinder 21 to prevent water from leaking between the two cells. I'll keep it. The air cylinder 21 receives pressurized air from the compressor 19, but instrument air is generally used and the compressor 19 is not needed in this case.

４に供給することになる。 First, valve 4 is opened, valve 6 is closed, and liquid is supplied by metering pump 3 to start filtration. Here, it is preferable that the metering pump is one that does not cause a change in flow rate at a pressure of about 2 kg/cm2, and since there is a buffer chamber 23, the stock solution is transferred to the filter chamber 23 after degassing.
It will be supplied to 4.

度レベルにより変化するが、１回の測定時間は５
乃至10分程度で充分である。 Here, since the pressure gauge 22 is attached to the buffer chamber 23, there is no liquid contact and no corrosion occurs. Immediately after completing the measurement, stop the metering pump 3,
The valve 4 is closed and the air in the air cylinder 21 is evacuated to push up the cell 9 according to a command from the computer. Furthermore, the valve 6 is opened so that the cleaning water 5 enters the liquid supply cell 7 and overflows while pushing up the paper tape 16. When the supply of cleaning water is stopped, the water in the liquid supply cell 7 flows out from the valve 6, and cleaning is completed. After the paper tape 16 has moved a predetermined distance, the cell 9 is pressed down and a second measurement is started in the same manner as described above. Overload and overtime vary depending on the turbidity level, but one measurement time is 5
About 10 minutes is sufficient.

It becomes possible to automatically manage Momotozuki turbidity removal equipment, freshwater generation equipment, etc.
また従来の定圧法自動濁度指数計と比較して、
計装機器の数が少なく、極めて単純なため、総合
誤差が少くなり、高精度の測定値が得られる。 Also, compared to the conventional constant pressure automatic turbidity index meter,
Because the number of instrumentation devices is small and extremely simple, the overall error is small and highly accurate measurements are obtained.
