Recently, the Suichuan County South Wastewater Treatment Plant, a key construction project of Suichuan County in 2025 undertaken by Tongyong Environmental Protection Group, has successfully entered the trial operation stage. At present, the equipment of all treatment units in the plant area has fully completed installation and commissioning, and the system has officially entered the water quality adaptation and commissioning cycle. Through building a refined and intelligent wastewater treatment system, the Group will continuously enhance the county’s wastewater treatment capacity and build a solid barrier for the protection of Suichuan County’s water ecological environment, the improvement of human settlements, and green and high-quality development.

Breaking Regional Challenges and Building a Full-Chain Water Treatment System

The total construction scale of the Suichuan County South Wastewater Treatment Plant is 50,000 m?/d, with the current implementation scale of 20,000 m?/d. Its service scope fully covers the south area of Suichuan County, Meijiang Town, and Yunling Industrial Park, effectively solving problems such as decentralized regional wastewater treatment and insufficient treatment capacity, and greatly improving the coverage rate of urban wastewater collection and the harmless treatment rate.

The project is equipped with a full set of standardized wastewater treatment structures and buildings, and simultaneously improves the off-site main wastewater pipeline network, building a full-chain, efficient wastewater treatment system of “wastewater collection—biochemical treatment—advanced purification—compliant discharge.”

Cutting-Edge Processes Empower Multiple Purification Barriers

The project core adopts the combined wastewater treatment process of “two-stage A/O reaction tank + secondary sedimentation tank + high-efficiency sedimentation tank + continuous sand filter,” integrating biochemical treatment and physicochemical advanced purification technologies to achieve gradual degradation. It has significant advantages such as strong shock resistance, stable operation, and excellent effluent quality. The effluent strictly implements the Grade A discharge standard of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB18918-2002).

Multiple Purification Barriers

Craftsmanship and Fine Service, Strictly Guarding the Bottom Line of Quality and Safety

After installation was completed, technical personnel immediately carried out comprehensive commissioning, repeatedly verifying operation results under simulated conditions of different water quality and quantity, and promptly troubleshooting hidden dangers. At the same time, the project department integrated safety management throughout the entire process, regularly carried out safety inspections and pre-job training, focused on controlling risks in work at heights, temporary electricity, and confined spaces, and made every effort to safeguard the bottom line of safe production.
