High-salinity wastewater from oil/gas fields features high mineralization (4k–150k mg/L), complex ions, high COD, and pollutants like oil/solids. Treatment challenges include microbial inhibition, equipment corrosion, and tech limitations (biological adaptability, physical/chemical energy costs). Solutions: pretreatment, salt-tolerant biological processes, advanced oxidation/membranes, salt/organic recovery. Key techs: evaporation (high desalination, high energy), membranes (efficient, fouling-prone), ion exchange (selective, high regeneration cost), biological methods (eco-friendly, water-quality sensitive). Must comply with China's environmental laws and industry standards.

The treatment of shale gas fracturing flowback fluid wastewater is a complex and critical process aimed at reducing environmental pollution, protecting water resources and realizing the resource utilization of wastewater.In the process of shale gas fracturing flowback fluid treatment, MVR evaporation technology introduces wastewater into the evaporator and uses heat energy to evaporate the water in the wastewater, thereby reducing the amount of wastewater.

To meet increasingly stringent environmental regulations and emission standards, petrochemical enterprises are actively seeking advanced wastewater treatment solutions that enable reduction, reuse, and recycling of industrial effluents. One of the most critical goals in this domain is achieving Zero Liquid Discharge (ZLD)—a process that ensures complete recovery of usable water and solid separation of all dissolved contaminants.

A comparison between Low-Temperature Evaporator (LTE), Mechanical Vapor Recompression (MVR), and Multiple-Effect Evaporator (MEE)

In the fields of industrial wastewater treatment, high-salt waste liquid concentration, biopharmaceutical purification, etc., low-temperature evaporation technology has gradually become the mainstream choice of the industry due to its high efficiency, energy saving and environmentally friendly characteristics. This article will give you a comprehensive understanding of the current mainstream low-temperature evaporation process from the perspectives of technical principles, core processes, and applicable scenarios.

Most methods for treating pesticide wastewater use physical and chemical methods, including adsorption, extraction, hydrolysis, oxidation, membrane separation, etc. Among them, thermal technology, as one of the supporting technologies for zero discharge of wastewater, mainly includes membrane distillation (MD), flash evaporation (MSF) technology, multi-effect evaporation (MED) technology, mechanical compression evaporation (MVR) and other technologies. Thermal method is to use heating and concentration to remove the light components of the solution in the form of fractions, and the heavy components are concentrated to increase the concentration of the solution.

Zinc-nickel alloy wastewater mainly contains harmful substances such as nickel, zinc, ammonia nitrogen, COD, etc. It has complex components and many complexes. Therefore, to treat this kind of wastewater, the complexing agent must be removed first, otherwise the heavy metal ions cannot be precipitated.

Through the case study of fluorine-containing high-salt mother liquor wastewater treatment in a large fine chemical enterprise in my country, the process of high-salt mother liquor wastewater treatment in fine chemical enterprises is explained.

This article will introduce in detail the entire process of wastewater treatment in six major industries, including fine chemicals, coal chemicals, petrochemicals, surface treatment, hazardous waste, mechanical processing and other industries, to help readers fully understand the wastewater disposal process of various industries.
