摘要
该工程对重庆沙坪坝区某污染场地进行治理修复,修复内容为污染土壤中单一六价铬污染土壤的量约5432.6m3;场地含有机物污染土壤的量约1930.8m3。工程对采用异位还原稳定化技术对单一六价铬污染的土壤进行无害化处置,处置后的土壤运往填埋场进行安全填埋处置。对混合污染土壤采用水泥窑协同处置技术进行处置,处置量约2000m3。
A contaminated site in Shapingba district of Chongqing was repaired. The amount of single hexavalent chromium contaminated soil in the contaminated soil was about 5432.6 m 3, the amount of contaminated soil containing organic matter in the site was about 1930.8 m 3. An ectopic reduction stabilization technology was used for the treatment of a single hexavalent chromium contaminated soil. After harmless treatment, nearly 5000 m 3 of soil was disposed of in a safe landfill. The mixed contaminated soil was treated by cement kiln co-processing technology, and the disposal amount was about 2000 m 3.
