Sludge turned into a new material for environmental protection — brick making

“In addition to incineration of power generation and fertilizer production, dirty and smelly sludge can also be transformed into an environmentally friendly building material through automated production.” The construction of a comprehensive sludge production line allows more sludge to be comprehensively utilized. New technologies open up new ways of ecological governance. “Slimy and smelly sludge […]

Case Study: 3x140MW Biomass Coupling Retrofitting in a UK Power Plant

A British power plant is located in Ashington, England. In March 1972, a power plant in the United Kingdom was put into operation as a supporting power plant for local smelters. The installed capacity of the power plant is equipped with 3 pulverized coal furnace units, each equipped with a 140MW steam turbine generator, for […]

What are the possible directions and possibilities for China’s biomass energy industry

Unlike the particularity of garbage and livestock manure, biomass fuel for agricultural and forestry waste is most likely to move to a large-scale, high-efficiency, low-cost large-scale coal-fired power plant biomass-coupled power generation model. In terms of technology and operation, because European countries have nearly 20 years of experience in large-scale coal-fired power plant biomass-coupled power […]

Thinking about green sustainable restoration of farmland

Select the best restoration technology through sustainability evaluation Different regions in my country have different climatic conditions, soil properties, and sources of farmland pollution, which may lead to different best ways to rehabilitate contaminated farmland. Sustainability assessment can be used to select the best remediation technology. At the same time, when designing a restoration plan […]

Current status of remediation of farmland contaminated soil in my country

With the rapid development of my country’s social economy, industrial activities and agricultural activities have brought serious soil pollution problems, which have brought huge risks to my country’s ecological environment and human health. According to the “National Survey Report on Soil Pollution Status” issued by the Ministry of Environmental Protection, the actual rate of spot […]

Research on Application of Sludge Ceramsite

As an important product of sludge resources, sludge ceramsite has the characteristics of stable chemical properties, small density, good heat resistance and rich pores. It has been widely used in construction, environmental protection, gardening and other fields. In the use of building materials, the use of lightweight ceramsite for the preparation of lightweight aggregate concrete […]

Analysis of influencing factors of preparing ceramsite from sludge

1. Influence of sludge content The ratio of raw materials is a key step in the preparation of ceramsite. It is necessary to comprehensively consider the influencing factors such as the amount of sludge, the chemical composition, the plasticity of the blank, and the economy. When using urban sludge and coal gangue as raw materials […]

Feasibility of preparing ceramsite with sludge

Sludge preparation of swelled ceramsite must meet two basic conditions: ① The raw material contains enough gas-generating components (such as illite, hematite, pyrite, dolomite, etc.); ② generates enough glass phase under high temperature conditions to encapsulate the generated gas. The main components of raw materials for firing ceramsite are generally SiO2 and Al2O3. Al2O3 produces […]

Preparation of ceramsite by resource utilization of sludge

Sludge is a by-product produced in the process of urban water treatment. It has the characteristics of high water content and low strength, and often contains harmful components such as pathogenic bacteria, heavy metals and toxic, harmful and difficult-to-degrade organic matter. If not properly disposed of, it will easily cause two Secondary pollution. Traditional sludge […]
