Product Overview
This high-efficiency sewage treatment plant integrates lamella clarifier technology with biological treatment, achieving rapid solid-liquid separation and deep pollutant removal . The lamella clarifier—composed of inclined parallel plates (60° angle)—increases the sedimentation area by 5-8 times compared to traditional horizontal clarifiers, reducing the plant’s footprint by 60% . The system handles sewage volumes from 50m³/d to 5000m³/d, with effluent meeting national Grade A discharge standards (GB 18918-2002) . It is suitable for large residential communities, industrial parks, and urban fringe areas lacking centralized sewage infrastructure, featuring automatic operation and low maintenance costs .
Product Features
Efficient Solid-Liquid Separation
The lamella clarifier’s inclined plates shorten the sedimentation distance of suspended solids (SS), enabling SS removal rates of over 98% . It also incorporates a sludge scraper system that automatically collects settled sludge, reducing manual cleaning frequency .
Enhanced Biological Treatment
Combines anoxic-oxic (A/O) biological reaction with the lamella clarifier: the A/O module decomposes organic matter (BOD removal rate ≥95%) and denitrifies nitrogen (ammonia nitrogen removal rate ≥90%), while the clarifier ensures clear effluent . The biological tank uses porous polyurethane filler, which increases microbial attachment area by 30% compared to conventional fillers .
Weather Adaptability
The plant’s enclosed structure with thermal insulation maintains stable operation in extreme temperatures (-20°C to 50°C) . In cold regions, an internal heating system keeps the biological tank temperature above 10°C, preventing microbial activity decline .
Smart Monitoring
Equipped with online sensors for pH, COD, SS, and turbidity, which transmit real-time data to the PLC control system . The system automatically adjusts aeration volume and sludge discharge frequency based on water quality changes, ensuring consistent treatment efficiency .
Applications
Large Residential Communities
Serves communities with 5,000-50,000 residents, treating domestic sewage and reusing part of the effluent for landscape irrigation and road cleaning—saving 30% of tap water consumption for the community .
Industrial Parks (Light & Heavy Industry)
Treats mixed wastewater from machinery manufacturing, electronics, and chemical industries. For example, it reduces SS in machinery cleaning wastewater from 800mg/L to ≤10mg/L, meeting industrial discharge requirements .
Urban Sewage Pumping Stations
Acts as a pre-treatment unit for large urban sewage systems, reducing the load on central treatment plants by separating suspended solids and partially decomposing organic matter .
FAQ
How often does the lamella clarifier need cleaning?
The automatic sludge scraper operates daily, and the plates require chemical cleaning (using 5% hydrochloric acid) every 6 months to remove scale. The system alerts operators when cleaning is needed via the control panel .
Can it handle shock loads (sudden increase in sewage volume)?
Yes, the plant has a 20% buffer capacity. When sewage volume exceeds the design capacity by up to 20%, the lamella clarifier’s high sedimentation efficiency and the biological tank’s microbial reserve maintain stable effluent quality .
What is the sludge disposal method?
The collected sludge has a moisture content of 95%, which can be dewatered to 60% using a plate-and-frame filter press (optional accessory). The dewatered sludge is suitable for landfill or composting .
Is the plant noisy during operation?
The main noise sources are aeration blowers, which are installed in sound-insulated enclosures. The noise level at the plant boundary is ≤55dB, complying with residential area noise standards .
