In industrial production processes such as electroplating, metallurgy, chemical engineering, and pickling, a large amount of complex-component and highly-polluting mixed heavy metal waste liquid containing phosphoric acid and sulfuric acid is inevitably produced. If these waste liquids are not handled properly, they will cause serious and long-lasting harm to the environment. How to safely, efficiently and economically handle such waste liquids has become a severe challenge for many industrial enterprises.
I. Challenges in the Treatment of Phosphoric Acid-Sulfuric Acid Heavy Metal Waste Liquids
Such waste liquids usually have the following characteristics, which result in inefficient or costly traditional treatment methods:
High acidity: A highly acidic environment places extremely high demands on the corrosion resistance of the equipment material.
High salt content: High levels of phosphate and sulfate ions, prone to causing scaling and blockage.
There are many types of heavy metals: they contain various heavy metal ions such as copper, nickel, chromium, zinc, and cadmium, and are highly toxic.
Complex composition: May contain organic substances, suspended solids, etc. The treatment process must have strong resistance to shock loads.
II. Advantages of Baihuipu Environmental Evaporation Treatment Technology
In response to these challenges, Baohupu Environmental Protection, leveraging its years of technological expertise, has introduced an efficient and stable equipment for the evaporation treatment of phosphoric acid, sulfuric acid and heavy metal-containing waste liquids. This equipment employs the evaporation crystallization process and is a key technology for achieving the reduction of waste volume, resource utilization, and "zero discharge" of the waste liquids.
Core technical highlights:
1. Corrosion resistance and scale prevention design:
High-quality materials: The main equipment and core components are made of special metals such as titanium, Hastelloy alloy, and high-grade stainless steel, or non-metallic materials such as graphite and fluoroplastics, ensuring long-term stable operation in strong acid and high salt environments.
Anti-scaling technology: Through unique fluid dynamics design, online cleaning system and seed crystal technology, it effectively delays and removes scale formation within the equipment, ensuring heat transfer efficiency and continuous operation cycle.
2. Efficient energy utilization:
MVR evaporation technology (mechanical vapor recompression): The secondary steam generated during evaporation is heated and pressurized by a compressor, and then reused as a heat source. This significantly reduces the consumption of fresh steam, with energy consumption being only one-third of that of traditional multi-effect evaporation, and the operating cost is extremely low.
Multi-effect evaporation technology (such as triple-effect evaporators): Multiple evaporators are connected in series. The secondary steam generated by the first effect serves as the heat source for the second effect, effectively recovering thermal energy. This technology is suitable for enterprises with stable and inexpensive steam sources.
3. Complete resource utilization and harmless disposal:
Wastewater reduction: After evaporation, over 90% of the water is separated out. After condensation, it can be reused in production or discharged in compliance with standards.
Heavy metal enrichment and recovery: The heavy metal ions in the waste solution, after evaporation and concentration, form concentrated solutions or crystalline salts, which significantly reduce the volume and make it easier to further extract valuable metals or safely landfill them as hazardous waste, greatly reducing the cost of hazardous waste disposal.
