Corrosion Resistant Integrated Domestic Sewage Treatment Equipment, Automatic Control WTP

Our Corrosion Resistant Integrated Domestic Sewage Treatment Equipment is a fully packaged, skid-mounted water treatment plant tailor-made for long-term, high-stability domestic sewage purification in complex and harsh working environments. Different from ordinary sewage treatment devices that are prone to rust, aging and structural damage in humid, saline and corrosive scenarios, this automatic WTP adopts full anti-corrosion structural design and high-grade resistant materials throughout the whole system. It perfectly solves the points of short service life, frequent maintenance and declining treatment efficiency caused by equipment corrosion in coastal areas, mining zones, humid subtropical regions and remote outdoor projects. Highly integrated with biochemical treatment, filtration, disinfection and intelligent control modules, the equipment requires no complicated civil engineering, features plug-and-play installation and fully automatic operation, becoming the ideal cost-effective solution for residential communities, rural settlements, construction camps, resorts and remote domestic sewage treatment projects worldwide.

Corrosion resistance is the core competitive advantage of this integrated sewage treatment equipment. The main body of the tank and shell is made of high-strength fiberglass reinforced plastic (FRP) and thickened carbon steel with multi-layer anti-corrosion coating, abandoning ordinary carbon steel and thin metal materials that are easy to oxidize and corrode. The internal wall adopts professional epoxy anti-corrosion coating, which undergoes high-temperature curing and secondary anti-rust treatment, effectively resisting the corrosion of organic sewage, acidic and alkaline water quality, humid air and salt fog. All external pipelines, valves and accessory components are made of 304/316 stainless steel or anti-corrosion PVC materials, avoiding rust damage and pipeline leakage in long-term outdoor and wet working conditions.

The whole equipment passes strict salt spray and corrosion resistance tests, ensuring no peeling, no rust and no structural deformation after long-term outdoor operation. Compared with traditional ordinary sewage treatment equipment with a service life of only 3-5 years, our corrosion-resistant WTP extends the overall service life to more than 15 years, greatly reducing equipment replacement costs and later maintenance investment for users, realizing long-term stable operation with one-time investment and long-term benefits.

This automatic integrated sewage treatment plant adopts the optimized A2/O biochemical treatment process combined with advanced solid-liquid separation and ultraviolet disinfection technology, covering the complete sewage treatment process from pretreatment, biochemical degradation to standard effluent discharge. Firstly, domestic sewage such as kitchen wastewater, bathing water and toilet sewage enters the pretreatment grid tank to intercept large suspended solids, hair and debris, preventing subsequent pipeline and equipment blockage. Then the sewage enters the anaerobic tank and anoxic tank in sequence, where specialized microbial flora decomposes macromolecular organic pollutants, effectively degrading COD, BOD5 and completing denitrification and phosphorus removal to eliminate water body eutrophication.

After biochemical degradation, the sewage flows into the aerobic tank for further oxidative decomposition of residual organic pollutants and ammonia nitrogen. Through sufficient oxygen supply and microbial circulation, the water quality is fully purified. Finally, the purified water passes through the precision sedimentation and disinfection system to kill harmful bacteria, Escherichia coli and other pathogens. The whole treatment process operates in a closed tank body, which avoids secondary pollution, odor overflow and environmental impact. The effluent stably meets international discharge standards and can be reused for green irrigation, road cleaning and landscape water replenishment.

Equipped with a full-set intelligent PLC automatic control system, this automatic control WTP realizes 24-hour unattended intelligent operation. The system supports automatic water inflow adjustment, automatic aeration control, automatic sludge backflow and regular automatic equipment cleaning, which can intelligently adapt to the fluctuation of domestic sewage volume and water quality concentration. In case of abnormal water volume, equipment failure or pipeline blockage, the system will automatically trigger an alarm and record fault data, facilitating quick inspection and troubleshooting.

The human-machine interaction interface is simple and intuitive, supporting real-time monitoring of water quality indicators, equipment operating status and energy consumption data. Users can also select optional remote wireless monitoring function to view operating data and control equipment remotely. The automatic operation design greatly reduces manual intervention, saves labor operation costs, and solves the problem of difficult daily management of sewage treatment equipment in remote areas and unattended stations.

• Excellent Durability in Harsh Environments: The full anti-corrosion design enables the equipment to adapt to various harsh scenarios including high humidity, heavy rain, salt fog coast, saline-alkali land and mining industrial areas, with strong environmental adaptability and stable long-term performance.
• High Integration & Easy Installation: All treatment units and control systems are highly integrated as a whole, with compact structure and small floor space. No complex civil engineering and pipeline laying are required. The equipment can be put into use after simple connection of water and electricity, with short installation and commissioning cycle.
• Stable Standard Discharge & Water Reuse: The optimized biochemical process ensures efficient removal of organic pollutants, ammonia nitrogen, total phosphorus and other indicators. The effluent is clear and odorless, fully compliant with global environmental protection discharge standards, and supports on-site water resource recycling.
• Low Operation Cost & Labor Saving: The automatic control system realizes precise aeration and energy-saving operation, with low power consumption and low sludge yield. Unattended operation greatly reduces daily operation and maintenance costs, bringing higher economic benefits for users.

This corrosion-resistant automatic sewage treatment equipment is widely applicable for decentralized domestic sewage treatment. It is the best choice for remote villages, rural living communities, suburban residential areas, scenic spots, tourist resorts, highway and railway construction camps, mining field living areas, island settlements and other projects. Especially suitable for high-humidity and coastal corrosive environments where ordinary equipment is easy to be damaged, it provides reliable and professional sewage purification solutions for global decentralized living scenarios.
