FRP Integrated Sewage Treatment System for Hospital School Community Domestic Wastewater Purification Equipment
Product Spotlights
1. Basic Product Information
Product Name: FRP Integrated Sewage Treatment System
Applicable Water Quality: Domestic sewage generated in hospitals, schools, communities, and other similar small and medium-sized civil organic wastewater
Product Positioning: A modular, underground-installed, low-maintenance and fully automatic domestic sewage purification complete equipment. It serves as a standardized sewage treatment solution specially designed for small and medium-sized centralized residential areas and public buildings, effectively solving the problems of daily domestic sewage discharge, purification and standard reuse.
2. Product Core Overview
It overcomes the drawbacks of traditional concrete tanks such as complicated construction, severe leakage and short service life. Featuring integral anti-corrosion, compression resistance and aging resistance, the equipment can be buried underground without occupying ground space and requires no full-time on-duty personnel.
The process logic is optimized according to the water quality characteristics of sewage from hospitals, schools and communities, realizing efficient degradation and treatment of COD, BOD, ammonia nitrogen, total phosphorus, suspended solids and other pollutants in domestic sewage. In view of the high disinfection requirements and trace pathogenic bacteria contained in hospital sewage, a special enhanced disinfection module is equipped. The effluent quality stably meets multiple standards for municipal discharge, farmland irrigation and landscape water reuse, making it a preferred complete equipment for small and medium-sized civil sewage treatment scenarios.
3. Core Advantages of FRP Fiberglass Material
1. Superior Corrosion Resistance: The FRP fiberglass material is resistant to acid, alkali, sewage corrosion and humid aging. It will not rust or peel after long-term contact with sewage and sludge, completely solving the problems of rusty carbon steel equipment and leakage, weathering and cracking of concrete tank structures.
2. Ultra-long Service Life: The integral molding structure has no splicing gaps with stable overall performance, resisting geological settlement and surface pressure. Under normal operation and maintenance conditions, the service life can exceed 30 years, which is far longer than that of traditional sewage treatment equipment.
3. Lightweight and High Strength: The equipment features light overall weight and convenient transportation and installation. No large-scale civil engineering support is required, and the whole project can be completed through on-site hoisting and pipeline connection, greatly shortening the construction cycle.
4. Closed and Odor-free: The fully enclosed integrated structure achieves excellent airtightness, effectively preventing odor overflow, mosquito and fly breeding, as well as soil and groundwater pollution caused by sewage leakage, which is highly suitable for residential communities, campuses and other scenarios with high environmental requirements.
4. Core Process and Working Principle
The equipment adopts a combined process of modified A/O biological treatment, physical-chemical sedimentation and advanced disinfection with fully automatic closed-loop operation. The core treatment process is as follows:
1. Homogenization and Regulation Unit: Collect fluctuating daily sewage from hospitals, schools and communities, balance water quality and water volume, buffer the impact of peak sewage discharge, ensure stable operation of subsequent processes and avoid treatment efficiency fluctuation caused by instantaneous high-concentration sewage.
2. Anaerobic Degradation Unit: Anaerobic microorganisms decompose macromolecular organic matters and suspended pollutants in sewage, degrade part of COD, break the colloidal structure of sewage, reduce the treatment load of subsequent processes, and realize preliminary sludge reduction.
3. Anoxic Denitrification Unit: Complete denitrification reaction of sewage, efficiently remove excessive pollutants such as ammonia nitrogen and total nitrogen in water bodies, solve the eutrophication problem of domestic sewage, and meet strict municipal discharge standards.
4. Aerobic Biochemical Unit: As the core treatment unit, it uses high-efficiency activated sludge flora to deeply degrade BOD, COD and organic pollutants, thoroughly decompose most organic impurities in sewage and realize the purification of core water quality indicators.
5. Sedimentation and Separation Unit: Adopt an inclined tube sedimentation structure to rapidly separate the mud-water mixture after biochemical treatment, trap suspended sludge. The supernatant flows into the next unit, while the sludge is automatically refluxed, and a small amount of residual sludge is discharged periodically.
6. Advanced Disinfection Unit: Tailored for hospital and public service scenarios, it adopts a dual disinfection mode of sodium hypochlorite or ultraviolet sterilization to kill Escherichia coli, pathogenic bacteria and other harmful microorganisms in sewage, eliminate the risk of pathogen transmission and ensure safe effluent discharge.
