sludge bricks

“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 […]

biomass power generation

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 […]

biomass 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 […]

Green 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 […]

polluted soil

Similar to the restoration of industrially contaminated sites, the environmental sustainability considerations of farmland restoration are divided into two parts. The first part is the harm to human health caused by the migration and exposure of pollutants in the soil, usually through quantitative analysis of health risk assessment. The second part is the various effects […]

soil polluted

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 […]

particles of sludge

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 […]

sludge particles

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 […]

Preparation of ceramsite from 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 […]
