基于制砖法处置水基钻井废屑和市政污泥
Disposal of water-based drilling waste and municipal sludge based on brick making method
选取水基钻井废屑和市政污泥作为原料,通过改变市政污泥掺量、烧结温度等参数,制备烧结砖,并对其性能进行测试。研究表明,当市政污泥绝干掺量为10%~15%、烧结温度为950℃、保温时间为2 h,制得的烧结砖性能符合国家标准《烧结普通砖》中MU10的要求。市政污泥掺量低于15%时,烧结温度是影响烧结砖性能的主要因素;污泥掺量过高时,烧结砖内部空隙增加,烧结温度对烧结砖的性能没有影响。通过水基钻井废屑和市政污泥的协同处理,不仅减少了它们对环境的危害,实现了工业固废的高效利用,还为可持续能源开发提供了新的思路。
Water-based drilling waste and municipal sludge are selected as raw materials to prepare the fired bricks through changing the dry content of municipal sludge,firing temperature,and so on,and the performance of the fired bricks is tested.Results show that the fired bricks meet the requirements of China’s national standard “Fired Common Bricks” with a MU10 performance when the dry content of municipal sludge is 10%-15%,the firing temperature is 950℃,and the holding time is 2 hours.As the dry content of municipal sludge is less than 15%,the firing temperature is the main factor affecting the performance of fired bricks.As the dry content of municipal sludge is too high,the internal pores of fired bricks increase,and the firing temperature has no effect on the performance of fired bricks.Through synergistic treatment of water-based drilling waste and municipal sludge,not only does it reduce their harm to the environment and achieve efficient utilization of industrial solid waste,but it also provides a new idea for sustainable energy development.
