M'madzi processing zimbudzi mankhwala zipangizo

Magwero opangira madzi otayira m'madzi

Njira yopangira: kusungunuka kwa zinthu zopangira → kukhetsa nsomba → kuyeretsa → kuyika mbale → kuziziritsa mwachangu Zopangira madzi oundana kusungunuka, kutsuka madzi, kuwongolera madzi, kupha tizilombo, kuyeretsa ndi njira zina kumatulutsa madzi onyansa, Zoyipa zazikulu zomwe zimatulutsidwa m'madzi ochapira. ndi malo ochitira msonkhano ndi CODcr, BOD5, SS, ammonia nitrogen, etc.

Njira zamakono zamakono

Chifukwa cha kukhetsedwa kosagwirizana kwa madzi owonongeka a m'madzi owonongeka komanso kusinthasintha kwakukulu kwa khalidwe la madzi, m'pofunika kulimbikitsa njira zochizira chisanadze kuti tipeze zotsatira zokhazikika.Madzi otayira amatengedwa ndi gululi kuti achotse zinthu zina m'madzi, ndipo zolimba zoyimitsidwa monga chikopa cha nsomba, zometa za nyama, ndi mafupa a nsomba zimalekanitsidwa asanalowe m'thanki yowongolera.Chida chothandizira mpweya chimayikidwa mu thanki, chomwe chimakhala ndi ntchito monga kununkhira komanso kufulumizitsa kulekanitsa mafuta m'madzi onyansa, kuwongolera kuwonongeka kwamadzi onyansa ndikuwonetsetsa kuti chithandizo chamankhwala chotsatira chachilengedwe chikuyenda bwino.Chifukwa cha kuchuluka kwa mafuta m'madzi otayira, zida zochotsera mafuta ziyenera kuyikidwa.Chifukwa chake njira yochizira isanakwane imaphatikizapo: kusefera ndi kukweza mpope chipinda, thanki yoyandama mpweya, thanki ya hydrolysis acidification.

Kukonza zofuna

1. Mkhalidwe wautsi wamtundu wa zotayira zonyansa umakwaniritsa mulingo woyamba womwe wafotokozedwa mu "Comprehensive Wastewater Discharge Standard" (GB8978-1996).

2. Zofunikira paukadaulo:

① Njira * *, yodalirika mwaukadaulo, komanso yankho labwino kwambiri pazachuma likufunika.Kukonzekera koyenera ndi kaphazi kakang'ono kumafunika.

② Malo akuluakulu apamadzi amadzimadzi amakhala ndi konkriti yachitsulo pamwamba pa nthaka.

③ Madzi olowera amalumikizidwa kudzera papaipi ya konkriti, yokwera pansi -2.0m.Pambuyo podutsa pachitsime cha metering, madzi amaponyedwa mu chitoliro cha tauni kunja kwa fakitale.

Mulingo woyamba wotchulidwa mu "Comprehensive Wastewater Discharge Standard" (GB8978-1996): unit: mg/L suspended solids SS ＜ 70;BOD ＜ 20;KODI <100;Ammonia nayitrogeni <15.
