Introduction

一、Product Introduction

The buried integrated sewage treatment equipment from Haipuo Environmental Protection Group is a comprehensive organic wastewater treatment system developed by combining years of practical engineering experience and proprietary research with advanced domestic and international technologies. Constructed from high-quality, corrosion-resistant materials such as fiberglass (FRP) and stainless steel, the unit integrates mature and stable biological treatment processes to efficiently remove pollutants—including COD, BOD5, and ammonia nitrogen—from wastewater. Specifically designed for domestic sewage and similar industrial organic wastewater, the system ensures effluent quality consistently meets national discharge standards and supports optional reclaimed water reuse systems to facilitate resource recovery.

As an integrated unit designed for full underground installation, the system features a compact, modular structure that eliminates the need for a dedicated equipment building; the main unit can be completely buried, preserving valuable surface space. It overcomes the drawbacks associated with traditional civil-engineered sewage stations—such as long construction periods, large footprints, complex O&M, and high energy consumption. Thanks to its stable performance, low investment cost, superior treatment efficiency, and ease of maintenance, it has become a mainstream solution for treating domestic sewage and small-to-medium-scale industrial organic wastewater. Highly adaptable to diverse settings—including towns, rural areas, residential communities, healthcare facilities, tourism sites, and industrial/mining zones—it offers a cost-effective, high-value solution for decentralized sewage treatment.

二、Product Advantages

1. Fully underground installation: space-saving, aesthetically pleasing, and practical

The entire unit is designed for fully underground installation, eliminating the need for dedicated equipment rooms or auxiliary heating and insulation facilities. The surface area above the unit can be utilized for landscaping, roadways, or other purposes, thereby maximizing land resource efficiency. This solution perfectly addresses the needs of projects with limited space or tight land constraints, offering far superior site utilization compared to traditional wastewater treatment facilities.

2. Advanced biochemical process: stable treatment performance and high shock resistance

The system employs a plug-flow, two-stage biological contact oxidation process, delivering performance superior to traditional completely mixed or series-mixed biochemical processes. Compared to activated sludge systems, this unit features a more compact footprint and greater adaptability. It utilizes novel elastic 3D media characterized by a large specific surface area, facilitating rapid microbial biofilm formation and shedding; this ensures high pollutant removal rates under standard organic loads while effectively increasing dissolved oxygen levels. The system demonstrates excellent resilience against fluctuations in influent water quality and flow rates, ensuring stable operation, fundamentally preventing sludge bulking, and guaranteeing consistent compliance with effluent quality standards.

3. Low sludge production via endogenous oxidation: extended maintenance intervals and reduced costs

The biochemical system operates using a low volumetric load biological contact oxidation process; microorganisms exist in a state of endogenous oxidation, resulting in minimal sludge generation. Under normal operating conditions, sludge removal is required only once every 90 days or longer—accomplished via vacuum truck extraction or sludge dewatering and off-site transport. This significantly reduces the frequency of sludge disposal as well as the labor and material costs associated with operation and maintenance, resulting in minimal daily operational demands.

4. Dual-stage odor control design: eco-friendly and odorless

The equipment features a professional odor control system utilizing a dual-process approach—combining standard high-altitude exhaust with soil-based deodorization. This effectively decomposes and adsorbs odorous gases generated during sewage treatment, preventing odor dispersion and improving the surrounding environment. It resolves the common issue of odor nuisance associated with traditional sewage equipment, offering superior environmental performance suitable for locations with strict environmental standards, such as residential areas, hospitals, and scenic spots.

5. Fully automated intelligent control: unattended operation with safety and reliability

The sewage treatment system is equipped with a fully automated electrical control system and an intelligent fault alarm mechanism. Start/stop functions, process operations, and water treatment run automatically, eliminating the need for 24-hour on-site personnel. The system monitors operational status in real-time and triggers automatic alarms upon detecting faults; maintenance staff need only perform routine inspections and servicing. This high level of intelligence ensures safe and stable operation.

6. Corrosion-resistant, durable, and long-lasting; simple installation and rapid deployment

The main unit is constructed from high-quality, corrosion-resistant materials such as fiberglass (FRP) and stainless steel, offering exceptional resistance to corrosion, aging, and rust. It is highly adaptable to various environments and boasts a service life of over 50 years. Designed as an integrated, all-in-one unit, it simplifies on-site construction and installation. With its highly integrated design and advanced mechanical automation, the system can be rapidly deployed and put into operation.

三、Scope of Application

Haipuou buried integrated sewage treatment equipment is suitable for a wide range of scenarios. Capable of efficiently treating various types of mixed domestic sewage and similar industrial organic wastewater, it offers great versatility and flexible installation options, making it an ideal choice for decentralized sewage treatment. Specific application scenarios include:

1. Commercial and Healthcare Settings: Treatment of domestic sewage from hotels, restaurants, sanatoriums, hospitals, and similar facilities.

2. Urban and Rural Residential Settings: Treatment of domestic sewage from residential complexes, villa communities, rural areas, market towns, and villages.

3. Transportation Hubs: Treatment of public domestic sewage from railway stations, airports, seaports, and vessels.

4. Industrial, Mining, Cultural, and Tourism Settings: Sewage treatment for factories, mines, military camps, tourist attractions, and scenic resort areas.

5. Industrial Wastewater Settings: Purification and treatment of small-to-medium-scale industrial organic wastewater with characteristics similar to domestic sewage; supports upgrades for meeting discharge standards and implementing reclaimed water reuse.
