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.

In the field of environmental protection, the effective treatment of leachate has always been a very challenging task. Winsonda has achieved remarkable results in leachate treatment projects with its advanced technology and professional solutions. Two typical cases will be introduced in detail below.

At a time when the environmental protection industry is booming, there is a company that focuses on the comprehensive utilization of hazardous waste (hereinafter referred to as "the company"), which is constantly exploring and moving forward in the field of environmental services. With professional technology and perfect disposal lines, it is committed to contributing to environmental protection. However, in terms of wastewater treatment, the company has also faced many challenges.

In response to the current difficulties in oil and gas field wastewater treatment and to overcome the defects and shortcomings of traditional water treatment technology, Winsonda has continued to innovate and was the first to launch a low-temperature evaporation crystallization device, which has technical advantages such as short process flow, high stability, low treatment cost, strong anti-scaling performance, and resource-based disposal.

Common treatment methods for zero discharge of high-salinity wastewater include membrane separation, MVR and multi-effect evaporation technologies. Through these technologies, the salt concentration in the wastewater can be reduced so that the wastewater meets the environmental discharge standards.

In recent years, low-temperature evaporation technology has gradually become an ideal choice for oil and gas field wastewater treatment due to its high efficiency, energy saving and environmental protection.

This guide outlines the primary sources of high-salinity wastewater, the inhibitory effects of inorganic salts on microorganisms, and the latest biological treatment strategies used to manage saline wastewater.

Low-temperature evaporation technology is an efficient and energy-saving evaporation method. Low-temperature evaporation refers to an evaporation process with an operating temperature generally between 35 and 50 °C. It is particularly suitable for treating solutions with high concentrations, high salt content or heat-sensitive substances.

As the demand for energy continues to grow, efficient oil and gas extraction becomes increasingly vital. However, the process generates a significant volume of wastewater, which contains a mix of hydrocarbons, chemicals, and sediments.

Winsonda’s technology has been instrumental in achieving zero-discharge solutions, concentrating mine water, and reducing the concentration of high-salinity wastewater. Our evaporators are highly efficient, designed to meet environmental standards while offering cost-effective, energy-efficient solutions.

We will introduce the typical process route of zero emission of coal chemical wastewater and the key process to help achieve "zero emission" of wastewater.

In the current social ecosystem, pesticides play a vital role in improving the yield and quality of crops. However, the wastewater generated in their production process poses great challenges to the environment, especially the pollution of soil and water sources, which not only seriously threatens the natural ecological balance, but also poses potential risks to human health. Therefore, it is necessary to choose a suitable water treatment method for pesticide removal. Next, through the wastewater treatment case of a large listed agrochemical company in my country, we will explain the efficient treatment process of agrochemical wastewater.
