With the large-scale development of the sewage treatment industry and increasingly strict environmental control, key links such as the grid room, anaerobic tank, sludge concentration tank, and dewatering room of sewage treatment plants are prone to continuously release odorous pollutants such as hydrogen sulfide, ammonia, methyl mercaptan, VOCs, etc. These gases have the characteristics of low odor threshold, strong diffusion, and high corrosiveness. They not only seriously endanger the respiratory health of frontline workers, but also easily spread to sensitive areas such as residential areas and schools around the factory area, causing high-frequency environmental complaints, exacerbating people's livelihood conflicts, and meeting the environmental protection operation requirements of the sewage treatment industry. The traditional odor monitoring mode has obvious shortcomings: manual inspection is limited by harsh environments such as high humidity, high corrosion, and high dust, resulting in low efficiency and safety risks, making it difficult to achieve 24-hour continuous monitoring; The conventional fixed-point monitoring data lags behind and cannot dynamically capture the real-time fluctuations and diffusion trends of odor concentration, resulting in delayed warning of exceeding standards and delayed response of governance measures; At the same time, the environmental protection department lacks dynamic data support for off-site supervision of sewage treatment plants, making it difficult to accurately trace pollution sources and evaluate treatment effects.

Dynamic monitoring station for excessive odor warning in sewage treatment plantsEquipment Introduction

Product Principle
The OSEN-OU odor online monitoring system collects gases through a pump suction method for detection, and its core sensitive components use high-quality imported gas sensors with high sensitivity and outstanding repeatability; The instrument is controlled by an embedded microcomputer, which is easy to operate, fully functional, highly reliable, and has various adaptive characteristics; Paired with a touch LCD screen and LED display screen, data viewing is intuitive and clear, providing a good human-computer interaction experience.
monitoring parameters
In response to the environmental air quality monitoring needs of landfill sites and other scenarios, this product uses high-sensitivity sensor technology to simultaneously monitor the concentrations of various odor factors in the air, including parameters such as methyl mercaptan, methyl sulfide, dimethyl disulfide, styrene, hydrogen sulfide, ammonia, trimethylamine, carbon disulfide, etc. Meanwhile, based on the measurement data of these parameters, the dimensionless OU value of the odor was calculated using 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, over limit determination, and alarm operations.
