Monitoring project of a certain cigarette factory

Water Quality Monitoring Project in a Cigarette Factory

Based on the production process characteristics, water consumption node distribution, and environmental compliance requirements of the cigarette factory, this project integrates professional online water quality monitoring equipment with an information‑based control platform. With a core focus on precise monitoring and scientific management, it achieves comprehensive water quality monitoring of the entire production process, covering both process water use and wastewater discharge.

The project focuses on key nodes of production water use and wastewater discharge, with scientifically deployed monitoring points covering critical areas such as the inlet of the tobacco leaf drying workshop, the water use point of the tobacco shred production line, the recirculating cooling water system, the domestic water outlet of the factory, the inlet of the wastewater treatment station, and the compliant discharge outlet. This ensures full capture of water quality dynamics for both process water and wastewater.

Core and Auxiliary Monitoring Indicators

Core Indicators: Hardness and alkalinity.

Auxiliary Indicators: pH, electrical conductivity, turbidity, COD, ammonia nitrogen, total phosphorus, and others.

Hardness monitoring focuses primarily on calcium and magnesium ion content. Alkalinity monitoring focuses primarily on bicarbonate and carbonate content. The system strictly follows the water quality standards for the tobacco industry and the Integrated Wastewater Discharge Standard. Monitoring parameters and alert thresholds can be adjusted according to production process requirements, ensuring that the monitoring data are accurate and reliable, and providing precise data support for production water regulation and wastewater treatment process optimization, thereby helping to ensure cigarette production quality and equipment safety.

Hardness/Alkalinity Online Monitoring Equipment

This equipment offers core advantages of high stability, strong anti‑interference capability, and high precision. It effectively handles interfering factors in process water such as trace impurities and chemical residues, ensuring the accuracy of monitoring data for hardness, alkalinity, and other indicators.

The equipment integrates full‑process automation features including automatic sampling, automatic pretreatment, automatic detection, automatic cleaning, automatic calibration, and intelligent quality control. It can operate continuously 24/7, significantly reducing the workload of manual sampling and testing, avoiding human operational errors, and lowering operation and maintenance costs.

The equipment uses a power supply mode with mains electricity as the primary source and a backup power supply as a supplement, ensuring stable operation of monitoring points in both workshop and outdoor environments, and preventing power interruptions from affecting monitoring activities. It supports 4G wireless data transmission, enabling real‑time upload of monitoring data to the platform for real‑time data viewing, historical trend analysis, and automatic alerting for abnormal indicators. When hardness, alkalinity, or other indicators exceed the standard threshold, the system rapidly triggers multi‑level alert signals, allowing staff to promptly identify problems, adjust process water parameters or wastewater treatment parameters, and prevent risks such as equipment scaling, production quality fluctuations, and non‑compliant wastewater discharge.

Additionally, the project includes functions for data integration and analysis, generating water quality monitoring reports that provide intuitive data support for production management and environmental compliance inspections.

Project Outcomes and Significance

The implementation of this project has comprehensively improved the intelligence and precision of water quality control at the cigarette factory, effectively addressing the shortcomings of traditional monitoring methods. It has achieved closed‑loop management of “real‑time monitoring, precise early warning, rapid response, and full‑process control” for both process water and wastewater discharge.

The continuous and stable operation of the online water quality monitoring equipment not only provides accurate data support for the production management department to understand water quality dynamics, identify water quality risks, optimize process water parameters, and regulate wastewater treatment parameters, but also effectively prevents equipment failures and production quality issues caused by abnormal water hardness or alkalinity. This extends the service life of production equipment and reduces operation and maintenance costs. At the same time, it ensures that production wastewater is discharged in compliance with standards, fulfilling the company’s environmental responsibility.

The project helps improve the stability of cigarette product quality and promotes the green, low‑carbon, and high‑quality development of the industry.
