摘要：

Heat treatment followed by vacuum filtration or filter pressing is one method of dewatering sewage sludge. The concentrations of certain heavy metals and polynuclear aromatic hydrocarbons in raw sewage sludge, treated sludge cake and the resultant liquors have been determined in samples collected from three sewage treatment works in the United Kingdom utilising heat treatment. Mass balances have been calculated using the results obtained and the degree of resolubilisation of these materials which occurs during the treatment process has been determined. © 1979.
