At the beginning of 2024, in the bustling city of Shanghai, an important action on sewage treatment is underway at a power plant in Shanghai. A group of professional and dedicated engineers gathered by the sewage treatment pool of the power plant, focusing on a critical task of installing chloride ion monitoring equipment. This sewage treatment tank is responsible for the treatment of sewage generated during the production process of the power plant, and the content of chloride ions is crucial for the effectiveness of sewage treatment and whether the subsequent discharge meets the standards.

Under the careful guidance of the on-site supervisor, the chloride ion monitoring equipment was successfully installed. It will be like a loyal guardian, constantly monitoring the chloride ion content in the sewage treatment tank, providing accurate data support for the sewage treatment work of the power plant, ensuring that the sewage can be effectively treated and discharged in compliance with standards, and contributing to the protection of Shanghai's ecological environment.

Installation location:Circulating water treatment process section of sewage treatment tank

Monitoring factors:Chloride ion concentration in water

Installation of instruments:Online ion analyzer

Project principle introduction:

The circulating water system of the power plant is an important cooling system to maintain the normal operation of the power plant. Cooling towers are commonly used to cool down power plants. The principle of cooling towers is to introduce cold water into the cooling tower and continuously circulate it to cool down the unit. Considering that the circulating cooling system is a key component of gas power plants, and the Cl -, Ca2+, SO42- ions in water quality can cause difficulties such as corrosion and scaling of machinery and equipment, river raw water can be used for the power plant's circulating water system only after being treated to meet standards.

Instrument Introduction:

The chloride ion electrode of Lanjing Instrument is composed of high-performance single crystal membrane, annular liquid interface, and solid electrolyte composite, which has the characteristics of pressure resistance and pollution resistance. The online chloride ion electrode is an indicator electrode for measuring the concentration of chloride ions in aqueous solutions or indirectly determining the concentration of ions that can form latent complexes with chloride ions. Widely used in discharge monitoring fields such as sewage treatment, hot springs, mineral development, metallurgical industry, and industrial wastewater treatment process control.
