我国西南师大环境化学研究所经过3年艰苦攻关,最近研制成功“煤矸石陶瓷马赛克”。该项成果不仅减少了煤矸石对环境的污染,保护了耕地资源,而且具有造价低,耐酸、碱性强,节约原材料及能源等优点。我国年排放煤矸石大约为1亿吨。目前,我国堆积的煤矸石多达12亿吨,占地约10万余亩,对环境污染十分严重。1986年重庆市环保局将“利用煤矸石制备马赛克”科研课题下达给
After three years of arduous research, the Institute of Environmental Chemistry of Southwest Normal University in China has recently successfully developed a “gangue ceramic mosaic.” This result not only reduces the environmental pollution of coal gangue, protects the cultivated land resources, but also has the advantages of low cost, strong acid and alkali, and saving raw materials and energy. The annual discharge of coal gangue in China is about 100 million tons. At present, China has accumulated up to 1.2 billion tons of coal gangue and covers an area of about 100,000 mu, which is a serious environmental pollution. In 1986, the Chongqing Municipal Environmental Protection Bureau issued a scientific research project on “Using coal gangue to prepare mosaics”.
