Effects of Soil Amendments on In-situ Remediation of River Sediment
River course is an important part of urban construction and development.River course pollution has a negative impact on residents and ecological environment.In this paper,three soils of amendments,calcium nitrate,enzyme and humic acid were introduced into the field of in-situ remediation of river sediment.And,the restoration of river sediment and overlying water quality in each experimental groups were studies by monitoring the seven indicators of pH,EC,DO,ORP,NH4+-N,COD and TP in overlying water and sediment,respectively.This paper aims to preliminarily understand the practical effects of three soil amendments on in-situ remediation of river sediment through actual observation and experimental data.
