Zero Discharge of Heavy Metal Industrial Wastewater
The combined process of Shangchen Environment can increase the reuse rate of heavy metal wastewater to 99.6%, achieving efficient recycling of water resources
Heavy metal wastewater contains harmful ions such as lead and mercury, which are highly toxic and easy to accumulate. If discharged without treatment, it will seriously pollute the environment and threaten health
Pain point analysis
Heavy metal wastewater has a complex composition, and    traditional treatment is difficult to be efficient and costly.
There are various treatment technologies, but a single technology    is unable to cope with complex wastewater, making it difficult for    companies to choose.
As discharge standards are enhanced, corporate compliance    pressure increases dramatically and risks increase.
The technology is complex and costly, which puts high pressure on    enterprises and makes it unbearable for small and medium-sized    enterprises.
Necessity analysis
Effective wastewater treatment is the responsibility of the    company in environmental protection and is essential to improving    the environment.
Compliance treatment can improve the competitiveness of the    enterprise, win trust, and promote the enterprise to obtain policy    support and financing opportunities.
Advanced technologies ensure compliance with standards, prevent    pollution accidents, and reduce legal and economic risks.
Responding to the green development strategy, wastewater    treatment helps enterprises gain policy dividends.

Core Technology for Zero Discharge Treatment of Heavy Metal Wastewater
99.6% of wastewater is reused by adopting the combined process of “pretreatment + OSMMBR + SPNR + MVR" maximizing the recycling of water resources
Heavy metal high-precision removal technologyOSMMBR systemSpecial membrane concentration salt doubling technologySC-MVR evaporation crystallization and salt separation technology
Heavy metal high-precision removal technology ensures the complete removal of heavy metals by precisely controlling pH and ORP, adding chemicals, precipitation, filtration, and deep treatment.
Online monitoring and control: Automatic monitoring of pH and ORP, precise dosing.
Efficient stirring system: Fast stirring speed, reaction efficiency increased by 15 times.
Efficient filtration system: Combine various filter media, 3 times the dirt holding capacity, and long backwash intervals.
OSMMBR system can treat high-salt wastewater with salt-tolerant bacteria, retain activated sludge, and completely remove suspended solids to ensure that the effluent SS is close to zero.
High volumetric load: Strong adaptability and high-quality output water.
Small land occupation: No secondary sedimentation tank is required, small amount of sludge.
Efficient treatment: Rremove high-salt and high-difficult-to-degrade COD wastewater, good denitrification.
Modular design: Easy to expand, moveable, automatic management.
Long-life membrane material: modified PPSU, anti-pollution, easy to clean.
SPNR technology combines crude and refined desalination to concentrate wastewater 20-50 times, and the treated water can be directly reused in production.
It still has high desalination rate at high flow rate.
It has high mechanical strength and service life.
It is able to function at lower operating pressures.
It is less affected by factors such as pH value and temperature.
It has good chemical stability and high cost performance.
SC-MVR technology can achieve zero discharge of high-salt wastewater and salt separation and resource utilization through steam compression, which is energy-saving and efficient.
Efficient heat balance: Optimize heat energy utilization, and reduce the evaporation cost to 40~50 yuan/ton.
High-precision salt separation: Fractional crystallization to achieve industrial-grade by-product salt.
Fully automatic monitoring: Video monitoring and data transmission, accurate prediction and correction.
Stable operation: Multiple technologies are adopted to ensure long-term stable operation of the system.
