摘要
在分析污泥的各种处理方法如农用填埋,抛海以及回转窑焚烧等基础上,提出了采用污泥异比重流化床焚烧新技术.着重对污泥能量的利用进行分析,并对污泥在流化床内的结团与着火特性进行试验研究,对污泥焚烧后SO2、NOx、氟、氯以及重金属排放等进行了分析和试验,表明污泥流化床焚烧在技术上可行,污染物排放能满足环保要求,不致引起二次污染。是一种颇具应用前景的污泥处理方法。
On the basis of analysing the various methods for the disposal of sludge, such as agricultural land filling, throwing into sea and burning in revolving kilns,the authors have come up with a new type of sludge heterospecific-gravity based fluidized bed combustion technology with emphasis on the analysis of sludge energy utilization. An experimental investigation is performed of the sludge caking and ignitioncharacteristics when burned in the fluidizecl bed. Also analysed and tested are the emissions of SO2, NOx, fluorine, chlorine and heavy metals following the combustion of sludge, which show that the sludge combustion in the fluidized bed is technically feasible and the emissions of POllutants are within the limits demanded by environmental protection requirements with no risk of secondary pollution arising there from. One can therefore conclude the above-mentioned technology can be advantageously applied for the disposal of sludge.
