How to maintain the wastewater online monitoring system?

The wastewater on-line monitoring system is a special equipment for wastewater monitoring. Because the water quality it monitors is relatively poor, the internal devices of the equipment will be polluted by water impurities after long-term operation, which may cause its detection performance to decline. , At this time, it should be maintained. Let me introduce to you how to maintain the wastewater online monitoring system? How to maintain the wastewater online monitoring system 1. Regular calibration of the system: It is necessary to judge its calibration period according to the water quality monitoring of the wastewater online monitoring system. If the monitored wastewater is in poor condition, its calibration period needs to be shortened. Under normal circumstances, every Maintenance once a month can meet the calibration requirements of the wastewater on-line monitoring system, and be careful not to exceed the time limit specified in the manual. 2. Regular cleaning of the system: The wastewater online monitoring system usually has an automatic cleaning function, but in the case of poor water quality, there will be a large amount of suspended solids. After a period of time, the water collection and distribution pipelines, sensors, reaction tanks and Deposits appear in the peristaltic pump tube, which changes the sensor's Ling Mingdu, which leads to deviations in the detection performance of the wastewater on-line monitoring system. 3. Multi-point linearity test: Generally, in the wastewater on-line monitoring system, 4-6 concentration standard solutions are used uniformly in the linear range for testing, and its slope and correlation coefficient are calculated. If there is a significant change between the slope of the standard curve and the correlation coefficient, the performance of the wastewater on-line monitoring system should be checked under the premise of ensuring that the quality of the reagents is qualified and that there are no human factors. Normally, it is enough to check once every six months. It is to ensure that the system can be in good operating condition. Since the water quality detected during the operation of the wastewater online monitoring system contains a large amount of impurities, its maintenance and maintenance should be strengthened to avoid the detection performance degradation after the equipment is polluted.
