Iyi nyubako ikoresha ikoranabuhanga rigezweho ryo gutunganya amazi yanduye, cyane cyane hakoreshejwe uburyo bwa Sequencing Batch Reactor (SBR). Ubu buryo butanga umusaruro mwiza wo gutunganya, ubushobozi bwo gukora neza, kandi bugakoresha ingufu nke, bigatuma ibintu bikomoka ku bimera, azote, fosifore, n'ibindi bihumanya ikirere bikurwaho neza. Imyanda yavuwe yujuje ibisabwa mu cyiciro cya A byavuzwe mu "Ibipimo ngenderwaho byo Gusohora Imyanya Ihumanya ikirere ku Nganda Zitunganya Amazi yanduye mu Mijyi" (GB18918-2002).

III. Inyungu ku bidukikije n'umusanzu ku mibereho myiza y'abaturage
Imikorere myiza y'uru ruganda rutunganya amazi mabi yateje imbere cyane ibidukikije byo mu mijyi ya Xi'an. Rugira uruhare runini mu kurwanya umwanda, kurinda ubuziranenge bw'amazi yo mu nkengero z'imigezi yo muri ako gace, no kubungabunga ibidukikije. Mu gutunganya neza amazi mabi yo mu mijyi, uru ruganda rwagabanyije umwanda w'imigezi n'ibiyaga, rwongera ibidukikije byo mu mazi, kandi rugira uruhare mu gusana urusobe rw'ibinyabuzima. Byongeye kandi, uru ruganda rwazamuye imiterere y'ishoramari muri rusange mu mujyi, rukurura izindi nganda kandi rushyigikira iterambere rirambye ry'ubukungu bw'akarere.
