Application Background of Odor Online Monitoring Station in Sewage Treatment Plants

During the sewage collection and treatment processes in sewage treatment plants, a large amount of odorous gases are generated due to organic matter decomposition and sludge fermentation. Gases such as hydrogen sulfide and ammonia are not only pungent but may also cause damage to the respiratory and nervous systems of nearby residents. This has long plagued the people living in the surrounding areas and is prone to triggering environmental disputes between neighbors.

Traditional odor monitoring mostly relies on manual periodic sampling followed by laboratory analysis. This method not only has low monitoring frequency and delayed data feedback, making it difficult to capture real-time fluctuations and peaks of odor concentration, but also lacks timeliness in accurately locating odor sources and judging diffusion ranges. Moreover, the odor emission from sewage treatment plants is affected by factors such as meteorological conditions and the operation status of treatment processes, resulting in complex concentration changes. The limited coverage of fixed monitoring points is unable to meet the comprehensive and dynamic monitoring needs.
With the increasingly strict environmental protection regulations on odor pollution control and the continuous improvement of the public´s requirements for living environment quality, sewage treatment plants are in urgent need of a means to monitor odor conditions in a real-time, continuous and accurate manner. Against this background, the odor online monitoring station for sewage treatment plants has emerged, which can provide timely and reliable data support for the supervision of environmental protection departments, the optimization of odor treatment in sewage treatment plants, and the protection of the environmental rights and interests of surrounding residents.


Equipment Introduction

Product Principle

The OSEN-OU Odor Online Monitoring System collects gas for detection through a pump-suction method. Its core sensitive components adopt high-quality imported gas sensors, featuring high sensitivity and outstanding repeatability. The instrument is controlled by an embedded microcomputer, with convenient operation, complete functions, strong reliability and various adaptive characteristics. Equipped with a touch LCD screen and an LED display, it enables intuitive and clear data viewing and offers a good human-computer interaction experience.


Monitoring Parameters

To meet the environmental air quality monitoring needs of scenarios such as landfills, this product uses high-sensitivity sensor technology to simultaneously monitor the concentrations of multiple odor factors in the air, including parameters like methyl mercaptan, dimethyl sulfide, dimethyl disulfide, styrene, hydrogen sulfide, ammonia, trimethylamine, and carbon disulfide. Meanwhile, based on the measurement data of these parameters, the odor dimensionless OU value is calculated through the company´s self-developed algorithm. The system integrates functions such as automatic monitoring, statistical analysis, and data transmission, enabling 24-hour real-time monitoring, on-site data collection, exceeding-standard determination and alarm, etc.
