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 […]
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, […]
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.; […]
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. […]
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. […]
Industrial wastewater refers to wastewater, sewage and waste liquid produced in industrial production processes, which contain industrial production materials, intermediate products and products that are lost with water, and pollutants produced during the production process, summarizing chemical industrial wastewater, printing and dyeing industrial wastewater. 15 kinds of industrial wastewater treatment processes such as paper industry […]
In recent years, sludge dewatering technology has been greatly developed, and technological breakthroughs have focused on the development of conditioning agents before sludge dewatering and the improvement of dewatering machinery and equipment. At present, using sludge chemical conditioning + mechanical dewatering technology, sludge conditioning agent is added to the wet sludge raw mud to destroy […]
With the development of urbanization, the amount of garbage generated by the city is increasing, and then a problem is caused municipal waste solutions. Now people’s living standards have improved, and the use of some high-end durable goods will increase, which will inevitably increase the difficulty of garbage disposal. The common treatment methods and advantages […]
By adding a certain proportion of quicklime to the dewatered sludge and uniformly blending, the quicklime reacts with the moisture in the dewatered sludge to form calcium hydroxide and calcium carbonate and release heat. Sludge lime stabilization technology can effectively deodorize, sterilize, inhibit corrosion, dehydration, and passivate heavy metal ions. The typical process is as […]
The sludge incineration technology refers to the conversion of organic matter in the sludge to CO2, H2O, N2, etc. under a certain temperature and sufficient aerobic conditions, and the heat released during the reaction is used to maintain the reaction temperature conditions. Sludge incineration technology is the most thorough sludge treatment method. It removes all […]
