This article focuses on the environmental protection and development of the coal chemical industry. The core content includes: the country's environmental protection regulations for the industry in terms of wastewater (including zero emission requirements), waste gas, solid waste treatment, energy efficiency, monitoring, etc.; the standards, treatment processes, technical bottlenecks and breakthrough strategies for zero wastewater discharge; the environmental impact of each link in the industrial chain; new pollution control technologies; the environmental, economic and social significance of zero emissions; the required environmental protection equipment, industrial distribution characteristics, and the development prospects of the industry relying on technological innovation to transform to a green and low-carbon environment. It emphasizes the need to balance environmental protection and economic benefits to achieve sustainable development.

Winsonda pure electric single-effect low-temperature evaporation concentration system relies on the heat pump principle to achieve efficient evaporation driven by electricity. It is widely used in solvent concentration in traditional Chinese medicine, food, chemical and other industries. It has high recovery rate, high COP value and explosion-proof intelligent characteristics. ​

Wastewater from oil and gas field development includes drilling mud, fracturing flowback fluid, oil and gas production wastewater, etc. After treatment, it can be reused in fracturing fluid and drilling fluid configuration, or used for urban miscellaneous water and cross-industry industrial water when it meets the standards. However, in actual implementation, due to the "cross-professional, cross-departmental, and cross-leadership" barriers and differences in government and enterprise positions, cross-reuse and cross-industry reuse are difficult. In addition, the contradiction between the high cost of water treatment and environmental protection standards and industry development needs is prominent, and the government, enterprises and environmental protection enterprises need to work together to solve it with new technologies and new management to achieve green development and resource circulation.

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.

In modern industry, liquid concentration is a key link in optimizing resource utilization, reducing transportation costs and increasing product value. As the industry's leading concentration technology solution, Winsonda low-temperature evaporator provides reliable and environmentally friendly support for various liquid concentration needs with its efficient low-temperature evaporation technology. Whether in the chemical, food, pharmaceutical or environmental protection fields, Winsonda low-temperature evaporator can bring significant improvements to your liquid concentration process.

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.
