摘　　要：采用异位化学氧化及固化稳定化技术联合修复重金属-总石油烃复合污染湖泊底泥,底泥中六价铬、镍、锌和总石油烃4项指标均超出浙江省《污染场地风险评估技术导则》(DB 33/T892-2013)中住宅及公共用地筛选值,修复底泥方量总计1.59×10^(4)m^(3)。项目竣工验收时底泥质量满足《污染场地风险评估技术导则》和《地下水质量标准》Ⅳ类水质标准,可回用作为路基材料。工程的成功实施为类似湖泊污染底泥修复提供了参考和借鉴。Using ex-situ chemical oxidation and solidification stabilization technology to jointly repair heavy metal-total petroleum hydrocarbon composite polluted lake sediment,the four indicators of heavy metal chromium,nickel,zinc and total petroleum hydrocarbon in the sediment all exceeded the screening value of residential and public land in"Regulations"of Zhejiang Province′s"Contaminated Site Risk Assessment Technology Guide"(DB 33/T892-2013)the total amount of repaired sediment is 1.59×10^(4)m^(3).When the project is completed and accepted,the quality of the sediment meets the Grade IV water quality standards in the Technical Guidelines for Risk Assessment of Polluted Sites and the Groundwater Quality Standard,and can be reused as roadbed materials.The successful implementation of the project provides a reference for the restoration of polluted sediments in similar lakes.
