1. Project Overview

This project serves as a demonstration initiative for decentralized rural wastewater treatment in Longhai District, Zhangzhou City. Eight treatment stations were constructed, each with a capacity of 100–300 m³/day, covering villages throughout Dongyuan Town. Dedicated to treating rural domestic sewage, the project addresses critical gaps in rural environmental infrastructure and supports the advancement of beautiful countryside development and improved rural living conditions.
