What are the ways for sludge recycling?

As people are paying more attention to sustainable economic development, the resource utilization of treated sludge has also attracted more and more attention. In recent years, with the development of Chinas economy and the unceasing advancement of urbanization, urban sludge has gradually increased. The traditional methods are sludge landfill, sludge farming and sludge incineration. But the sludge landfill will cause some environmental problems. In order to meet the three principles of harmlessness, reduction and recycling in sludge treatment, the sludge low-temperature wall-breaking carbonization treatment technology is adopted to fully realize the resource utilization of sludge. The sludge low-temperature wall-breaking carbonization process can recover about 80% of the organic energy in

KOSUN VC-1000 Series Cuttings Dryer playing an important role in drilling waste management

Cuttings dryer is a continuous screen type centrifuge with automatic feed control designed for liquid-solid separation. It is designed to recover drilling fluid from cuttings by exerting very high centrifugal acceleration force on cuttings to improve fluid separation effect from cuttings. The cuttings dryer system catches any lost mud and returns it to active mud system. The recovery system works well with diesel, mineral oil and synthetic oil based mud. The system has proven to be more efficient with synthetic oil based mud due to the ease of oil separation from larger cuttings. Synthetic oil based mud system has a higher mud value, and this cuttings dryer is relatively critical equipment for the system, which makes it more attractive from economical and practical points of view. In addit

Some basic knowledge about heavy metal pollution in soil

In recent years, Chinas emphasis on soil remediation, namely soil ecological environment improvement and soil pollution control, is obvious to all. Soil pollution is concealed and lagging, while soil pollution control and soil remediation are undoubtedly faced with complex pollution components and high technical thresholds. Especially, the soil contaminated by heavy metals is easy to accumulate, difficult to transfer, and has a high level of hazard. Originally, ecology is a whole, and soil contamination prevention needs to clear obstacles from all aspects and overcome difficulties. For example, the standards in the field of soil remediation are not perfect, and experts have been researching, discussing and compiling updated standards. Not long ago, the China Association of Environmental Pr

The environmental protection industry will be further integrated, and technological advantages will be crucial.

In recent years, with the release of pollution control demand, the development of Chinas environmental protection industry has been accelerated, and the number of enterprises has increased dramatically. As the industry competition intensifies, the importance of technology is further highlighted, and the industrial consolidation trends have emerged. According to the Development Report of China Environmental Protection Industry (2018) issued by China Association of Environmental Protection Industry (CAEPI), the total operating income of Chinas environmental protection industry is expected to exceed CNY two trillion in 2020. The growth rate of the environmental protection industry is much higher than that of the national economy. At the 20 th China IE expo held in April 2019, there were 2,047

The function of tailings dry discharge in sludge treatment process

The first stage is sludge concentration to preliminarily reduce the volume of sludge; The second stage is sludge digestion to decompose the organic matter in the sludge; The third stage is sludge dewatering to further reduce the volume of sludge; The fourth stage is sludge disposal to treat the final sludge by some means. The above typical sludge treatment process can achieve the reduction, stabilization, harmlessness and recycling of sludge after treatment. (1) Reduction: Because the sludge has high water content with large volume and fluidity. After the above process, the sludge volume is reduced to one-tenth of its original volume, and its state is converted from liquid into solid, which is convenient for transportation and consumption. (2) Stabilization: The content of organic matter i
