Nk’uko bigaragazwa n’umwaka wa 2018 wa Shanghai Municipal Local Standard for Integrated Discharge (DB31 / 199-2018), isohoka ry’amazi mabi y’uruganda rukora amashanyarazi rukoreshwa na Baosteel Co., Ltd. ruherereye ahantu h’amazi yunvikana. Kubera iyo mpamvu, igipimo cyo gusohora ammoniya azote cyaragabanutse kiva kuri mg / L kigera kuri 1.5 mg / L, kandi igipimo cy’ibisohoka kiva kuri 100 mg / L kigera kuri 50 mg / L.

Mu gice cy’amazi y’impanuka: Muri kariya gace hari ibidendezi bibiri byamazi. Sisitemu nshya yo kugenzura byikora kuri azote ya amoniya yashyizweho kugirango ishobore gukurikirana buri gihe urugero rwa azote ya azote mu bidengeri by’amazi. Byongeye kandi, hashyizweho pompe nshya ya sodium hypochlorite ikoreshwa, ihujwe na tanki yo kubika sodium hypochlorite ihari kandi ihujwe na sisitemu yo gukurikirana azote ya amoniya. Iboneza rituma igenzura ryikora kandi ryuzuye kubidendezi byombi byimpanuka.

Muri sisitemu yo gutunganya amazi yicyiciro cya mbere cya sitasiyo itunganya amazi yimiti: Sisitemu yo kugenzura byikora kuri azote ya ammoniya yashyizwe kumurongo wogusobanura, ikigega cy’amazi B1, ikigega cy’amazi B3, ikigega cya B4, n’ikigega cya B5. Izi sisitemu zo gukurikirana zifatanije na sodium hypochlorite yo gupompa kugirango ishobore kugenzura ikoreshwa ryikora mugihe cyose cyo gutunganya amazi.

Ibikoresho Byakoreshejwe ：

NHNG-3010 Kumurongo wa Automatic Ammonia Nitrogen Monitor

YCL-3100 Sisitemu yo guteganya ubwenge kubwamazi meza

Kugira ngo hubahirizwe ibipimo ngenderwaho byavuguruwe, uruganda rukora amashanyarazi rwa Baosteel Co., Ltd. rwashyizeho ibikoresho byo gukuramo azote ya amoniya hamwe n’ibikoresho byo kwitegura ku isoko y’amazi. Sisitemu isanzwe yo gutunganya amazi mabi yarakozwe neza kandi avugururwa kugirango azote azote ya ammonia hamwe n’ibinyabuzima bivurwe neza kugirango byuzuze ibisabwa bishya. Iterambere ryemeza gutunganya amazi mabi mugihe kandi neza kandi bigabanya cyane ingaruka zibidukikije zijyanye no gusohora amazi mabi.

Ni ukubera iki ari ngombwa gukurikirana urugero rwa azote ya ammoniya ku masoko y'amazi yo gusya?

Gupima azote ya amoniya (NH₃-N) ku ruganda rukora ibyuma ni ingenzi cyane mu kurengera ibidukikije no kubahiriza amabwiriza, kuko uburyo bwo gukora ibyuma busanzwe butanga amazi y’amazi arimo amoniya atera ingaruka zikomeye iyo asohotse nabi.

Ubwa mbere, azote ya amoniya ni uburozi cyane ku binyabuzima byo mu mazi. Ndetse no mubutumburuke buke, birashobora kwangiza amafi nubundi buzima bwo mu mazi, bigahagarika imikorere yabyo, kandi biganisha ku rupfu rwinshi. Byongeye kandi, ammonia irenze mumazi yamazi itera eutrophasique - inzira aho ammonia ihinduka nitrate na bagiteri, bigatuma imikurire ya algae ikura. Ururabyo rwa algal rugabanya ogisijeni yashonze mu mazi, bigatuma "ahantu hapfuye" aho ibinyabuzima byinshi byo mu mazi bidashobora kubaho, bikangiza cyane urusobe rw’ibinyabuzima byo mu mazi.

Icya kabiri, uruganda rukora ibyuma rwubahirizwa byemewe n’ibipimo by’ibidukikije by’igihugu ndetse n’ibanze (urugero, Ubushinwa Bwuzuye Bwangiza Amazi y’Ubushinwa, Amabwiriza y’ibyuka bihumanya ikirere). Ibipimo ngenderwaho bishyiraho imipaka igabanya ubukana bwa azote ya azote mu mazi yanduye. Gukurikirana buri gihe byemeza ko urusyo rwujuje izo mipaka, rwirinda ihazabu, guhagarika imirimo, cyangwa inshingano zemewe n'amategeko biturutse ku kutubahiriza.

Byongeye kandi, ibipimo bya azote ya ammoniya ni ikimenyetso cyerekana imikorere ya sisitemu yo gutunganya amazi mabi. Niba urugero rwa ammonia rurenze urwego rusanzwe, rwerekana ibibazo bishobora guterwa mugikorwa cyo kuvura (urugero, imikorere mibi y’ibice bivura ibinyabuzima), bituma abajenjeri bamenya kandi bagakosora ibibazo vuba - kubuza amazi y’amazi adatunganijwe neza cyangwa adakoreshwa nabi kwinjira mu bidukikije.

Muri make, gukurikirana azote ya amoniya ku ruganda rukora ibyuma nigikorwa cyibanze cyo kugabanya ingaruka z’ibidukikije, kubahiriza ibisabwa n’amategeko, no gukomeza kwizerwa mu gutunganya amazi mabi.
