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 […]
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 […]
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 […]
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 […]
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 […]
In recent years, with the development of China’s economy and the continuous advancement of urbanization, the scale of construction of urban sewage plants has been continuously expanded, and the degree of sewage treatment has been gradually improved. The aerobic wastewater treatment technology is generally applicable to medium and low concentration organic wastewater due to short […]
There are two main ways to dispose of hazardous wastes: geological disposal and marine disposal. Marine disposal includes deep-sea abandonment and incineration. Land disposal includes land cultivation, permanent storage or reserve storage, land landfill, deep well filling and deep formation disposal, among which land landfill disposal technology is the most widely used. Marine disposal has […]
In general, the NOX generated by waste incineration can be divided into two types: thermal NOX formed by oxidation of N in air under high temperature fuel condition and waste NOX formed by incineration of N element in waste. When the temperature of fuel in the furnace is low, the NO_x produced by garbage accounts […]
Sludge bricks refer to sludges that have been treated with certain treatments, mixed with other raw materials or admixtures, pressure-formed, and calcined to produce sludge bricks. There are two methods for sludge brick making. One is to use the dried sludge directly for brick making, and the other is to use sludge to burn ash […]
The aerobic fermentation technology of sludge is that under aerobic conditions, microorganisms oxidize a part of the absorbed organic matter into a simple inorganic substance through absorption, oxidation, decomposition and the like, and release the energy required for the growth activity of the microorganism; Another part of the organic matter is synthesized into a new […]
