INDUSTRIAL WASTEWATER

Industrial wastewater refers to the wastewater and waste liquid discharged in the process of production, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water, causing environmental pollution, especially major cause of water pollution. Although the treatment of industrial wastewater has been started as early as the end of the 19th century, due to the complex composition and changeable nature of many industrial wastewaters, there are still some technical problems that have not been completely solved.
According to the degree of pollution, industrial wastewater can be divided into two categories: production wastewater and production sewage. Production wastewater refers to water that is slightly polluted or the temperature increases during use (such as equipment cooling water); production wastewater refers to water that is seriously polluted during use, most of which are seriously harmful.

According to the chemical properties of the main pollutants contained in industrial wastewater, it can be divided into inorganic wastewater mainly containing inorganic pollutants, organic wastewater mainly containing organic pollutants, mixed wastewater containing both organic and inorganic substances, heavy metals Waste water, waste water containing radioactive substances and cooling water contaminated only by heat. For example, wastewater from electroplating and mineral processing is inorganic wastewater, and wastewater from food or petroleum processing is organic wastewater.
According to the products and processing objects of industrial enterprises, it can be divided into papermaking wastewater, textile wastewater, tanning wastewater, pesticide wastewater, metallurgical wastewater, oil refining wastewater, etc.
According to the main components of pollutants contained in wastewater, it can be divided into acidic wastewater, alkaline wastewater, phenol-containing wastewater, chromium-containing wastewater, organic phosphorus-containing wastewater and radioactive wastewater.

Metallurgical Wastewater
The main characteristics of metallurgical wastewater are large amount of water, many types, and complex and changeable water quality. JX Purification can give you a professional design project. Read More
Beneficiation Wastewater
The mineral processing wastewater has the characteristics of large water volume, high suspended solids content and many types of harmful substances.The beneficiation wastewater mainly passes through the tailings dam, which can effectively remove the suspended solids in the wastewater, and the content of heavy metals and flotation reagents can also be reduced. If the emission requirements are not met, further treatment should be carried out. JX Purification can give you a professional design project. Read More
Acid Wastewater
Acid-base wastewater is highly corrosive and needs to be properly treated before it can be discharged. JX Purification can give you a professional design project. Read More
Food and Beverage Industry Wastewater
The food and beverage industry has a wide range of raw materials and a wide variety of products, and the amount and quality of discharged wastewater vary greatly. We have developed a feasible treatment process for soybean protein isolate and whey wastewater, extracting soluble protein and oligosaccharides separately, recycling high-concentration organic matter that cannot be easily degraded by raw materials, and at the same time ensuring that the wastewater can be reused after treatment. during production process. The application of this technology has opened up a new way to solve the problem of protein isolate whey wastewater treatment in the soybean industry. Read More
Chemical Industry Wastewater
Chemical industry wastewater mainly comes from production wastewater discharged from petrochemical industry, coal chemical industry, acid and alkali industry, fertilizer industry, plastic industry, pharmaceutical industry, dye industry, rubber industry, etc. Read More
Printing and Dyeing Industry
The printing and dyeing industry consumes a lot of water, usually 100-200 tons of water per ton of textile printing and dyeing, of which 80%-90% is discharged as printing and dyeing wastewater. Commonly used treatment methods include recycling and harmless treatment. The use of membrane separation technology to remove impurities, purify and concentrate the reaction product liquid in the production of reactive dyes can not only concentrate the product, but also obtain high-quality liquid products. The system implements componentized design, with a high degree of equipment automation, which can realize PLC control, easy operation and maintenance, and easy standardized management. Read More
Pulp and Paper Industry
Papermaking wastewater mainly comes from the two production processes of pulping and papermaking in the papermaking industry. The treatment of paper industry wastewater should focus on improving the recycling water rate, reducing water consumption and wastewater discharge, and at the same time actively exploring various reliable, economical and efficient treatment methods that can fully utilize the useful resources in wastewater. We use Ro ,UF system can decrease the pollution of this industry. Read More
Heavy Metal Industry
We design a closed circulation treatment and reuse system for heavy metal wastewater, which can purify wastewater and recover heavy metals. The concentration, recovery and separation technology of heavy metal wastewater not only solves the problem of environmental pollution in the industry, but also creates economic benefits for enterprises.
