| Abstract: | In order to propose an effective method for the reclamation of sewage sludge in Jinhua city,dewater sewage sludges from the typical wastewater treatment plants were sampled and analysed.The results show that all sludge samples are alkalescent with a pH value 6.89,and have a moisture content 75%.The samples have plenty of organic matter,N,P,K,and the heavy metals are relatively low in content and are up to the Control Standards for Pollutants in Sludges from Agricultural Use(China).Basic quality has been ana... |
