Soil pollution treatment

The aim of research: Determination of greywater characteristics from some buildings in Hanoi city; Explaination of the principle of removing the main pollutants out of greywater by using laterite with multi soil layering engineering; Determination of decomposition rate coefficients of BOD5, COD and NH4 + -N. The number of laterite layer is calculated based on these coefficients; Successful greywater treatment from building by using laterite with Multi Soil Layering engineering and the treated effluent meet up the National Regulations

Pot and field trials were carried out using sediment dredged from the port of Bremen (Germany) and deposited in a settling basin near Bremen; the sediment is polluted with Cd and Zn. Five iron-bearing materials were added to the soil (1% pure Fe in soil dry matter) to immobilize the heavy metals: ‘Red mud from the aluminium industry, sludge from drinking-water treatment, bog iron ore, unused steel shot and steel shot waste.
