Municipal Engineering Sewage Treatment Equipment

Municipal Engineering Sewage Treatment Equipment

Product Overview

SUN EURO POLO integrated sewage treatment equipment adopts a modular design, combining core process units including bar screens, equalization tanks, biological treatment units, sedimentation tanks, and disinfection devices into standardized box-type or steel-structure configurations, forming a compact and highly efficient sewage treatment system. The treatment capacity ranges from 50 m³/day to 10,000 m³/day, with flexible configuration options based on actual project requirements. This equipment is particularly suitable for municipal engineering applications where space is limited, construction schedules are tight, and rapid commissioning is required.

Working Principle

The integrated sewage treatment equipment operates based on Biological Contact Oxidation (BCO) or activated sludge process principles. Sewage first passes through mechanical bar screens to remove larger suspended solids and floating debris, then enters an equalization tank for flow and quality balancing. The pre-treated sewage then flows into the biological treatment unit, where microorganisms attach to the biological carrier media to form a biofilm under aeration conditions. Through aerobic metabolic processes, organic pollutants in the sewage are decomposed into carbon dioxide and water. The biologically treated sewage flows into a sedimentation tank where activated sludge separates from the treated water. The clarified water passes through a disinfection unit (typically ultraviolet or sodium hypochlorite disinfection) to eliminate pathogenic microorganisms before compliant discharge. The settled sludge is partially recycled to the biological tank to maintain system sludge concentration, with excess sludge periodically removed for further treatment. The entire treatment process can be fully automated, equipped with PLC control systems and remote monitoring capabilities.

Product Features

First, highly integrated design. All treatment units are integrated into one or multiple standardized modules, significantly reducing civil engineering work and occupying only 30% to 50% of the land area of traditional sewage treatment plants-particularly suitable for municipal projects with limited land resources. Second, quick and easy installation. Equipment is pre-fabricated and debugged at the factory; on-site work only requires foundation construction and equipment lifting connection, reducing installation time by over 60% for rapid commissioning. Third, high degree of automation. Equipped with intelligent control systems enabling unattended operation with automatic adjustment of aeration rates, recycle ratios, and chemical dosing, reducing operating labor costs. Fourth, stable and reliable operation. Made from high-quality corrosion-resistant materials with mature process technology, the equipment has a service life exceeding 15 years with low failure rates. Fifth, aesthetically pleasing appearance. The equipment enclosure can be designed for landscape integration, harmonizing with the municipal environment and reducing NIMBY (Not In My Backyard) effects. Sixth, flexible expansion capability. Supports parallel operation of multiple units or later capacity upgrades to accommodate growing treatment demands from urban development.

Application Scenarios

This equipment is widely used in urban domestic sewage treatment stations, centralized sewage treatment for residential communities, municipal road supporting sewage treatment facilities, public toilet wastewater treatment in parks and scenic areas, and wastewater management at transportation hubs such as railway stations and subway stations. In municipal projects across Southeast Asia, Africa, and the Middle East, SUN EURO POLO integrated sewage treatment equipment has successfully helped local government departments achieve full coverage of sewage collection and treatment, significantly improving regional water environmental quality. In an African municipal project, a 500 m³/day equipment array achieved stable effluent quality meeting local Grade 1B discharge standards, earning high praise from the municipal administration.
