Le projet global d'utilisation des eaux recycl\u00e9es dans la zone de d\u00e9veloppement \u00e9conomique de Ningyang adopte le mod\u00e8le EPC+O, avec une p\u00e9riode d'exploitation de 20 ans. L'\u00e9chelle de traitement des eaux recycl\u00e9es est de 20 000 m\u00b3\/j \u00e0 court terme et de 50 000 m\u00b3\/j \u00e0 long terme, en utilisant la coagulation, la s\u00e9dimentation, le filtre \u00e0 sable et l'U-RO. Le processus est reli\u00e9 \u00e0 la canalisation d'eau recycl\u00e9e existante et dessert le parc d'industrie chimique de la zone de d\u00e9veloppement du comt\u00e9 de Ningyang.<\/p>","protected":false},"excerpt":{"rendered":"
