The harm of leachate in MSW incineration plant
There are a lot of kitchen waste, high moisture content and low calorific value in China’s urban domestic waste. During incineration, fresh waste must be stored in the waste storage pit for 3-5 days for fermentation and ripening, so as to achieve the purpose of draining water and increasing calorific value, so as to ensure […]
Stabilization treatment of waste incineration slag
Curing / stabilizing treatment Before filling, it is usually necessary to solidify and stabilize the incineration ash flow, which can not only reduce the impact of leaching of toxic heavy metals in the ash on the geological environment, but also ensure the engineering safety. (1) curing. Solidification is a process in which hazardous wastes are […]

What regulations should be met for the pulverized coal preparation system of the cement plant production line?
The pulverized coal preparation system of the cement production line should be selected according to the process requirements of the kiln and the types of coal, coal quality and moisture. For the preparation of pulverized coal, a grinding system with drying should be used. Cement production line pulverized coal preparation system design should meet the […]
Optimization measures for rotary kiln process in cement plant
In recent years, coal resources have become tense and price costs have risen. In order to save costs, cement plants have to reduce the quality of raw fuels, coupled with the gradual decline in limestone grades, resulting in simultaneous reductions in the output and quality of rotary kiln systems. In order to improve this situation, […]
How is sludge treated?
Food industry wastewater The food industry has a wide range of raw materials and a wide variety of products. The amount of water and water quality discharged from wastewater are very different. The main pollutants in the wastewater are: solid materials floating in the wastewater, such as vegetable leaves, peels, minced meat, bird feathers, etc.; […]
How industrial waste is treated?
Printing and dyeing industrial wastewater The printing and dyeing industry uses a large amount of water. Generally, it consumes 100 to 200 tons of water per 1 t of textiles for printing and dyeing, of which 80% to 90% is discharged by printing and dyeing wastewater. Commonly used treatment methods are recycling and harmless treatment. […]
Environmental impact of municipal waste solutions
With the acceleration of urbanization and the improvement of residents’ living standards, the number of municipal waste solution has increased. In recent years, municipal solid waste has grown at an annual rate of 8% to 10%, and the growth of urban domestic waste has become a potential factor restricting the sustainable development of various countries. […]
