I-Shenyang Daxin ivuza iphrojekthi yokwelashwa kwezimo eziphuthumayo

Isici sephrojekthi

Isikali esikhulu: 0.94 million m ³   i-leachate, iphrojekthi enkulu kunazo zonke yokwelapha izimo eziphuthumayo emhlabeni jikelele.

Inselele enkulu: izinga eliphezulu kakhulu likagesi, ukugxila kwe-ammonia kanye nezinga eliqinile lokulahla ukungcola.

Isheduli yephrojekthi ejulile:

Hola 800 tons/d permeate phakathi nenyanga engu-1

Ikhiqiza amathani ayi-2,000/d ingene phakathi kwezinyanga ezi-3

Ukusebenza kahle okuphezulu: kwahlelwa amasethi angu-18 wezinhlelo zeziqukathi ze-Jiarong. Ikhwalithi ye-permeate ihlangabezane ngokugcwele nezinga lendawo lokuchithwa kwamanzi amdaka.

Imodeli entsha ye-Biz: I-Jiarong itshala imali ekusebenzeni kwephrojekthi futhi ikhokhisa imali yokwelashwa ngethani ngalinye lamanzi angcolile ahlanziwe.
