Progresses of Remediation Techniques for Polluted Sediment

Remediation techniques for polluted sediment are discussed in this paper. The remediation techniques contain physical treatment, such as dredging, capping, and bioremediation. Physical treatment can control contaminated sediment relatively easily, but cost too much, while bioremediation is just reversed. To access legal criterion and reduce cost, various techniques must be applied to treat the contaminated sediments according to their properties. Break down products were suggested to be reused after biodegradation.
