1. Project Overview

This project is a key water environment remediation initiative in Nancai Town, Shunyi District, Beijing. With a treatment capacity of 2,000 m³/day, it focuses on intercepting and treating sewage discharged from river outfalls throughout the township. The project eliminates black-odor water bodies, restores aquatic ecosystems, and serves as a core component in building a livable township characterized by clean waterways and green landscapes.

2. Core Project Details

Employs a combined “Hydrolysis + A/O + UF Ultrafiltration” process for efficient degradation of domestic sewage pollutants.

Treated effluent meets Class 1B standards under Beijing’s Integrated Discharge Standard of Water Pollutants (DB11/307-2013).

Establishes an integrated system for outfall interception, collection, and treatment, completely eliminating direct sewage discharge into rivers.

Tailored for decentralized township wastewater treatment with compact equipment design and straightforward operation and maintenance.

Includes coordinated river dredging and ecological restoration efforts, achieving dual benefits in water quality improvement and ecosystem protection.

3. Project Honors & Recognition

Selected as an Outstanding Water Environment Treatment Project in Shunyi District, Beijing.

Township river discharge outlet treatment model promoted by the Beijing Water Authority.

Significantly improved water quality in Nancai Town’s rivers, recognized as a “Demonstration Project for Civilized Urban District Development.”

Successfully passed joint inspection by local residents and government authorities, earning widespread recognition for its substantial environmental benefits.
