Deep Dewatering Technology and Analysis
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 […]
What are the municipal waste solutions?
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 […]
Sludge lime stabilization technology and analysis of its advantages and disadvantages
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 […]
Sludge incineration technology and analysis of its advantages and disadvantages
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 […]
Dioxin purification process in waste incineration
The traditional dioxin treatment method is called PAC method. The core of PAC method is to control the combustion temperature of garbage in the furnace above 850 C, the residence time of flue gas over 2S and the concentration of oxygen over 6%. Activated carbon has a large specific surface area, so long as a […]
Hazard waste solidification process
The solidification method is that cement, plastics, water glass, asphalt and other coagulants are mixed with hazardous waste to solidify, so that the harmful substances contained in sludge are sealed in the solidified body and not leached, so as to achieve the goal of stabilization, harmlessness and reduction. The solidification process can reduce the permeability […]
Comprehensive analysis of 15 industrial wastewater treatment processes
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 […]
Causes and prevention of deformation of rotary kiln cylinder
Equipment is the basis of production. Rotary kiln is the central equipment for cement production and one of the key points of equipment management. The rotary kiln is required to be round and straight, but it will be deformed due to various reasons during production, causing adverse effects such as heat of the tile and […]
Sludge Thermal Drying Technology and Analysis
The thermal drying of sludge refers to the process of removing moisture from the sludge through the heat transfer between the sludge and the heat medium. The sludge thermal drying system mainly includes sludge storage and transportation system, sludge drying system, sludge exhaust gas purification and treatment system, electrical automatic control instrument system and its […]
