Abstract
Because the sludge treating technology is at low level and the phosphorus sludge had polluted the environment seriously, the advantages and shortcomings about some kinds of processes to treat phosphorus sludge are compared in this article. It has put forward a clean and economical process to produce sodium hypophosphite product from phosphorus sludge.
Keywords
