Landfill leachate mainly comes from the water holding capacity of garbage itself, the liquid produced by garbage decomposition and the rainwater brought in during garbage collection and transportation. Landfill leachate has the characteristics of high ammonia nitrogen content, high concentration of organic pollutants, high salinity, complex components, large fluctuation range of water quality and quantity, […]
In recent years, the cooperative disposal of hazardous waste projects in cement kilns has shown explosive growth, and the market prospects are very broad, but the industrial development is still in its infancy. At present, there are five main problems in the cooperative disposal of hazardous waste in cement kilns in China: project direction, project […]
First, the raw sludge is pumped from the secondary settling tank to the other tank through the sludge pump to be separated from the supernatant. Since the moisture content of the raw sludge can usually reach 99.5%, the sludge must be concentrated and there are many feasible methods for reducing the volume of the sludge. […]
With the upgrading and adjustment of the national industrial structure, the production of machine-made aggregate has entered the industrial era, and the corresponding design, production and quality control standards have gradually improved. As an industrial product, machine-made aggregate not only promotes the change of market consumption concept, but also promotes the development of diversification of […]
I. Overview of Sandstone Aggregate Sandstone aggregate is the most basic component of concrete. Usually, 1.3-1.5m_3 loose aggregate is needed for every m_3 concrete. Therefore, for a project with a large amount of concrete, the requirement of sand aggregate is also quite large. The quality of aggregate directly affects the strength of concrete, cement dosage […]
With the improvement of the living standards of our residents and the development of urban economy, the construction of urban sewage treatment equipment in China has been continuously strengthened, and a large amount of sludge will be produced in the sewage treatment process. The composition of the sludge is extremely complex, and it is bulky, […]
First, What is sludge pyrolysis retorting gasification? Sludge pyrolysis retorting gasification is to use a composite heating mode to heat the sludge to 150 ° C ~ 600 ° C, the organic matter and water are separated from the solid phase and converted into gas phase; then enter the filter device to filter out the […]
Waste heat resource refers to the part of energy that is likely to be recovered and reused but not yet recovered under the current conditions. It is considered to be the fifth largest conventional energy after coal, oil, natural gas and water power. These waste heat resources can be used for power generation, driving machinery, […]
On May 21, Mr. Sadati, a client from East Asia, and his team came to our institute to discuss the construction of a 500-ton cement clinker production line. Accompanied by the relevant personnel of our institute, we inspected the production base and initially reached the intention of cooperation.
In recent years, the ceramisite industry has actively responded to the basic national policy of resources and environmental protection, using construction waste soil, municipal sludge and sludge as the main raw materials to produce ceramisite, which has achieved good economic benefits and greatly relieved the enormous pressure brought by environmental factors. Ceramic is widely used […]
