论述了湖泊污染底泥的环境疏浚工程技术，这是一项当今世界上崭新环保工程技术，作者根据国内湖泊环境疏浚第一例工程的经验和实践，提出了环境疏浚工程技术，包括该技术与工程疏浚技术的区别，疏浚方案的制定，适用机械的选型比较，以及泥浆的脱水干化，余水处理等，同时还提出了防止二次污染的各种技术和措施，为我国湖泊污染治理提供了一个有效的污染底泥疏浚技术。

This paper discussed environmental dredging engineering technology for sediment in lake, which is a new technique of the field in worldwide. The paper presented environmental dredging technique of lake sediment on the basis first environmental dredging engineering — Chaohei engineering of Lake Dianchi, including the nature of environmental dredging, technological process, main dredging facilities selection, the silt and its stockpile and dewater and treatment, as well measures to prevent pollution in environmental dredging. The technique developed is practical one to control pollution and eutrophication for Lakes all over the China.
