One of the main disposal ways of permitted discharge is water reclamation and reuse. Problems existing in the water reuse were discussed. The overall concepts of permitted discharge disposal were put forward , and the emphases were on the advanced treatment , the design of pipe network for the transport and distribution of reclaimed water , the disposal method of direct discharge to rivers or sea and estuary disposal , the diversion and design of regional channels , and other
