sewer sludge sludge sintered brick and preparation method thereof
The invention discloses a sewer sludge sludge sintered brick and a preparation method of the sintered brick. The sewer sludge sludge sintered brick is prepared from the following raw materials in percentage by dry basis mass: 20-30% of shale, 20-50% of muck, 20-40% of slag and 0-12% of sewer sludge. According to the physical and chemical properties of the sewer sludge, the shale, the muck, the slag and other raw materials are adopted for plasticity index regulation and control, then aging, brick making and forming, drying and tunnel kiln roasting are sequentially conducted, and the sewer sludge sintered brick is obtained. According to the method, the problem of secondary pollution caused by stacking treatment of the sewer sludge is fundamentally solved, inorganic mineralized substances inthe sewer sludge can be further utilized, finally, resource utilization is achieved, and certain environmental protection benefits, social benefits and economic benefits are achieved.
本发明公开了一种通沟污泥烧结砖及其制备方法，通沟污泥烧结砖的原料包括按干基质量百分比计的以下组分：页岩20～30％，渣土20％～50％，炉渣20～40％，通沟污泥0％～12％。根据通沟污泥的理化特性，采用页岩、渣土、炉渣等原料进行塑性指数调控，之后依次进行陈化、制砖成型、干燥、隧道窑炉焙烧后，得到通沟污泥烧结砖。本发明不仅从根源上解决了通沟污泥堆放处置产生的二次污染的问题，而且能够进一步利用通沟污泥中的无机矿化物质，最终既实现了资源化利用，又具有一定的环保效益、社会效益以及经济效益。
