Relevant Technology and Key Points of Waste Leachate Treatment

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, […]

What are the sludge treatment steps?

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. […]

Optimum Design of Manufactured Sandstone Aggregate Production Line

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 […]

Planning of gravel aggregate yard

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 […]

Treatment of heavy metals in municipal sludge

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, […]

Brief introduction of sludge pyrolysis retorting gasification process

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 […]

The Difference between Traditional Ceramic Granule Preparation and Sludge Ceramic Granule Preparation

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 […]
