The project feasibility report mainly investigates, studies and compares the main contents and supporting conditions of the project, such as market demand, resource supply, construction scale, process route, equipment selection, environmental impact, fund raising, profitability, etc., from the aspects of technology, economy and engineering, and makes a comparison of the possible financial, economic and social […]
Sandstone aggregate production line is one of the most upstream production lines in national infrastructure, which provides indispensable raw materials for various types of infrastructure. However, in the production process of sand aggregate, most of the production lines can not meet the original design needs, and at the same time, there will be some problems […]
In recent years, the state has promulgated a large number of regulations and systems on environmental protection and resource utilization. Environmental protection is the most important concern of major enterprises and factories. Once there are any environmental protection problems, enterprises are not only facing fines and rectification, but also likely to face such major events […]
The so-called sludge carbonization is a process that releases the water in the sludge by a certain means, while maximally retaining the carbon value in the sludge, so that the carbon content in the final product is greatly increased. There are four main types of sludge carbonization. 1.High temperature carbonization. It is not pressurized when […]
Biomass energy is the only renewable energy source that can be stored. It can replace fossil energy to reduce CO2. Therefore, it is a renewable energy with industrialization and large-scale utilization prospects. It is of great significance to the optimization of China’s energy structure. The development of biomass power generation is an important way to […]
Summary of Hazardous Waste Hazardous waste mainly includes industrial waste and medical waste. Industrial waste accounts for more than 70% and medical waste accounts for about 14%. Among the industrial hazardous wastes, 30% are waste acid and alkali, 14% are asbestos wastes and 10% are non-ferrous metals smelting wastes. In the source industries, 19% are […]
First、Process flow of sludge resource utilization The sludge resource utilization means that the sludge undergoes a chemical reaction in a closed, anaerobic and high-temperature state, and the sludge is subjected to high-temperature pyrolysis and carbonization to produce combustible gas and bio-carbon.Thereby effectively decomposing the sludge, realizing the resource utilization, protecting the environment and achieving benefits. […]
The rapid development of industrialization has highlighted the problem of environmental pollution on which human beings depend. The unreasonable disposal of various wastes harmful to the natural environment has resulted in the pollution of soil and groundwater. Soil pollution has the characteristics of concealment and irreversibility. It will not only directly or indirectly endanger human […]
Summary of Soil Thermal Desorption Technology Thermal desorption technology in soil remediation technology refers to the process that organic pollutants in soil are heated to a certain temperature by direct or indirect heat exchange under vacuum or when entering air, so that organic pollutants can be volatilized or separated from the polluted medium and enter […]
Most of the oil contained in the sludge is difficult to biodegrade and requires sludge treatment equipment. Many studies have demonstrated the efficient treatment of oil-bearing soils by bioremediation, but only for pollutants with high oil content. Most of the experiments were conducted in the laboratory, and there were few applications in the industry. Bioremediation […]
