ている。2. Description of the Related Art Conventionally, as a facility for treating domestic wastewater and the like, there is a membrane installation facility having a treatment tank 2 in which a membrane separation device 1 is installed as shown in FIG. The membrane separation device 1 is, for example, one in which plate-shaped membrane cartridges 4 are arranged at regular intervals in the upper part of a case 3 that is open at the top and bottom, and a diffuser 5 is installed below the membrane cartridge 4. A permeated water pipe 6 communicating with the membrane permeation side of the cartridge 4 is led out of the tank.

In the state where air is diffused through the gasifier 5, organic matter and nitrogen in raw water are removed by the action of activated sludge.

流している。At this time, the activated sludge mixed liquid 8 in the treatment tank 2
Is filtered by the membrane cartridge 4 by applying a suction pressure to the membrane permeation side of each membrane cartridge 4 through the permeated water pipe 6 by the pump 9 or using the natural head of the activated sludge mixture 8 as a filtration drive pressure. The membrane permeated water that has flowed into 6 is drawn out of the tank, and is discharged after disinfection.

洗、薬洗などしている。At this time, the membrane surface of the membrane cartridge 4 is cleaned by using the diffused air from the diffuser 5.
While the filtration operation is continued, pores are clogged and the filtration resistance is increased. Therefore, the membrane cartridge 4 is appropriately back-washed and washed.
【０００６】その際、定流量濾過方式で運転していれ

できる。At this time, if the operation is performed by the constant flow rate filtration method, the filtration resistance gradually increases in accordance with the contamination of the membrane. Therefore, it is possible to easily determine the membrane cleaning time by measuring the filtration pressure.

A remote monitoring system for a sewage treatment plant that is intended to be monitored has also been reported. As a terminal for remote monitoring in such a system, that is, as a display device, a personal computer or a workstation is generally used. In some cases, a display device specialized in remote monitoring is manufactured and incorporated in a control panel. Some are seen.

示装置としては気軽に利用できないのが現状である。However, commercially available products such as a personal computer that can be used as a display device have a problem in durability because they are not basically supposed to operate continuously for 24 hours. However, manufacturing a dedicated display device for continuous operation is extremely expensive due to the small number of display devices, and it cannot be used easily as a remote monitoring display device for membrane installation facilities such as septic tanks. It is the current situation.

い例も多い。In a sewage treatment facility such as a septic tank, there is a large discrepancy between the planned sewage amount and the actual inflow sewage amount. . For example, the inflow of sewage into a sewage treatment facility is usually about 1 to 16 hours, but in many cases, such as a septic tank in a factory, there is no inflow of sewage on holidays and the membrane separation device does not operate.

And a membrane contamination detecting means for detecting predetermined data serving as an indicator of membrane contamination, and a display provided at a remote monitoring position remote from the membrane separation device and displaying the data detected by the membrane contamination detecting means. The display means is configured to start and stop in conjunction with the start and stop of the intermittent filtration in the membrane separation device.

の問題を排除できる。According to the above construction, the display means for displaying the data detected by the membrane contamination detecting means is started and stopped in conjunction with the membrane separation apparatus for performing intermittent filtration, so that it is assumed to operate continuously for 24 hours. It is also possible to use a commercially available personal computer or the like as the display means, which eliminates the problem of durability.

圧力のみ監視する。In a membrane installation using a drainage pump as a filter driving means, the pressure on the suction side of the drainage pump decreases as the membrane becomes dirty and the filtration resistance increases. Thus, it is possible to easily judge the cleaning time of the membrane separation device. In this case, since no suction pressure is applied during non-filtration when the drain pump is stopped, only the pressure during filtration when the drain pump is driven is monitored.

Also in this case, the liquid level rise does not occur when the raw water supply pump is stopped and the non-inflow is not performed.
