In the denitrification process of sewage treatment plants, real-time and accurate monitoring of nitrate nitrogen concentration is the key to ensuring that the total nitrogen in the effluent meets the standard and optimizing treatment efficiency. Produced by Xiamen JingchuanSpecial self-cleaning nitrate nitrogen online analyzer for sewage treatment plantsSpecially developed for complex water quality conditions with high turbidity and high sludge content in sewage treatment plants, it has become the core equipment for intelligent monitoring of nitrate nitrogen and reducing operation and maintenance costs in sewage treatment plants with high-precision detection, automatic cleaning function, and stable operating performance.
Special self-cleaning nitrate nitrogen online analyzer for sewage treatment plant, produced in JingchuanofCore technological advantages
Accurate detection of working conditions in sewage treatment plantsBy using dual beam ultraviolet spectrophotometry and combining it with Jingchuan's self-developed water quality interference correction algorithm, the concentration of nitrate nitrogen in the range of 0-100mg/L in sewage treatment plants can be accurately measured. The error in the low concentration range (0-10mg/L) is ≤± 2%, and the error in the high concentration range (10-100mg/L) is ≤± 1.5%. In response to common interference factors such as suspended sludge, dissolved organic matter, and chromaticity in sewage, the built-in turbidity compensation module and spectral analysis technology effectively eliminate interference effects. Even in scenarios with large fluctuations in sludge concentration such as biochemical tanks and nitrification tanks, stable measurement accuracy can be maintained, providing reliable data support for denitrification process adjustment.
Automatic cleaning function reduces maintenanceSpecially designed for monitoring environments prone to pollution in sewage treatment plants, with an integrated water and gas dual flush self-cleaning system. The cleaning frequency can be automatically adjusted according to the turbidity of the sewage (1-24 hours adjustable), or forced cleaning can be triggered when abnormal detection data is detected. The measurement tank and sensor surfaces are alternately flushed with high-pressure water flow and compressed air to remove attached sludge, biofilm, and impurities. The cleaning process only takes 40 seconds, which does not affect normal monitoring, extending the equipment calibration cycle to more than 3 months, reducing 70% of manual maintenance workload compared to traditional analyzers, and reducing the labor intensity of operation and maintenance personnel.
Corrosion and pollution resistance, stable operationThe components that come into contact with water samples are made of 316L stainless steel and PTFE (polytetrafluoroethylene) materials, which can withstand the corrosion of corrosive substances such as acids, bases, and sulfides in sewage. The flow system adopts an anti clogging design, with a sampling tube diameter of 8mm and a built-in blowback device, which can effectively prevent sludge floc blockage and ensure continuous operation in high sludge environments such as aeration tanks and anoxic tanks. The overall protection level of the equipment reaches IP66, suitable for outdoor and workshop environments with high humidity and dust in sewage treatment plants. The working temperature range covers -10 ℃ -50 ℃, with an average time of over 10000 hours.
Intelligent linkage and data managementSupports 4-20mA analog signals, RS485 digital transmission, and Modbus protocol, seamlessly integrating with the central control system and PLC equipment of sewage treatment plants to achieve real-time monitoring and process linkage of nitrate nitrogen concentration. When the concentration exceeds the set threshold, an automatic sound and light alarm will be triggered and pushed to the management personnel's mobile phone for timely adjustment of aeration, dosing and other parameters. Built in large capacity data storage module can store monitoring data and cleaning records for more than 12 months, automatically generate daily/monthly/quarterly statistical reports, provide data basis for energy audit and process optimization of sewage plants, and help achieve a 15% -20% increase in denitrification efficiency.

Domestic Jingchuan nitrate nitrogen online analyzerMultiple application scenarios
Biochemical pool monitoringReal time tracking of the generation and consumption patterns of nitrate nitrogen in biochemical reactions provides a basis for aeration control in activated sludge processes, avoiding a decrease in treatment efficiency caused by the accumulation of nitrate nitrogen. After application in a municipal sewage treatment plant, the denitrification efficiency of the biochemical tank increased by 20% and the electricity consumption decreased by 12%.
Nitrification tank regulationAccurately monitor the nitrate nitrogen concentration at the endpoint of nitrification reaction, optimize the carbon source dosage and reaction time, and reduce reagent waste. In industrial wastewater treatment, the nitrification process can be adjusted through data feedback to reduce treatment costs by 25% for high ammonia nitrogen wastewater.
Online monitoring of effluentInstalled in front of the main discharge outlet, it monitors the concentration of nitrate nitrogen in the effluent in real time, warns in advance of the risk of exceeding the standard, and ensures that the discharged water quality meets the "Pollutant Discharge Standards for Urban Sewage Treatment Plants". Combined with self-cleaning function, it can maintain stable monitoring even when the water quality is turbid during the rainy season.
