          Taking advantage of incineration to disposal sludge holds certain advantages

              Sludge is a kind of organic debris, microorganism, particulate inorganic colloids, such as the composition of non plastids, sludge containing toxic organic pollutants and pathogenic microorganisms and heavy metals, will cause serious harm to the environment, with a sharp increase in sludge production, sludge reduction and by more and more people's attention. The composition of the sludge composition including solid inorganic phase and organic phase, the mobile phase of water and water solution components. Sludge reduction is mainly to reduce the water in the mobile phase, which capillary water, pore water and adsorbed water can by physical and chemical methods of sludge was modified and the reduction or removal, but the internal water only by burning dry processing technology to remove. Sludge incineration is the most thorough processing method, it can decompose the organic matter oxidation, thoroughly to kill pathogens, greatly improve the heavy stability, sludge incineration residual ash volume only mechanical dehydration of sludge volume of 10% and the processing speed of sludge fast and does not need to be stored for a long time, reduce the occupation of the area.
             The main direct incineration of sludge incineration, incineration after drying and burning three, direct incineration technology due to the high moisture content of sludge, thus a large number of fuel consumption, material consumption and high energy consumption, high operation cost; incineration after drying equipment investment cost is larger, but the processing cost is low, considering the economy and safety, has a price advantage; sludge incineration technology refers to sludge and other combustible mixed combustion, not only make full use of the calorific value of sludge, and achieves the purpose of comprehensive recycling of solid waste, only need to establish the sludge delivery system, simple system, convenient operation, considering the comprehensive utilization of solid waste angle of mixed incineration technology has become the preferred technology for sludge incineration.
             In abroad, there are much experience in the sludge incineration technology. Germany is one of the sludge production is the European country with the highest, at present in Germany every year about 250 million tons of sludge generated, 14 of them for incineration, 30% for agricultural compost, 56% for landfill; and sludge landfill disposal rate greatly decline in nearly ten years, incineration ratio increased year by year. Japan because of its small land area, so for the sludge treatment to achieve maximum reduction of as the ultimate goal. According to statistics, using incineration process of sewage treatment plant for disposal of sludge volume accounted for more than 60% of the sludge production in Japan and in the world at the top.
             There are many harmful matters produced in the process of incineration. These harmful matters will cause secondary pollution to environment. Therefore, control incineration temperature in incineration process, burning environment, process parameters and external adsorption agent and other conditions to suppress the generation of pollutants, thereby reducing sludge incineration of the risk of secondary pollution, promote sludge incineration treatment technology. In general the sludge incineration processing still need more long-term development, more need of contemporary science and technology workers continue to work hard.
