Makhalidwe ndi kasamalidwe ka madzi otayidwa m'makampani azaulimi ndi chakudya

Madzi oipa ochokera ku ulimi ndi kukonza chakudyaali ndi mawonekedwe omwe amawasiyanitsa ndi madzi otayidwa wamba am'matauni omwe amayendetsedwa ndi malo oyeretsera madzi oipa a anthu onse kapena achinsinsi padziko lonse lapansi: amatha kuwonongeka komanso alibe poizoni, koma amakhala ndi kuchuluka kwa okosijeni wachilengedwe (BOD) ndi zolimba zoyimitsidwa (SS). Kuphatikizika kwa madzi onyansa a chakudya ndi ulimi nthawi zambiri kumakhala kovuta kuneneratu chifukwa cha kusiyana kwa ma BOD ndi pH m'madzi onyansa kuchokera ku masamba, zipatso ndi nyama, komanso njira zopangira chakudya komanso nyengo.

Pamafunika madzi ambiri abwino pokonza chakudya kuchokera ku zipangizo. Kutsuka masamba kumatulutsa madzi omwe amakhala ndi tinthu tambirimbiri komanso zinthu zina zosungunuka. Itha kukhalanso ndi ma surfactants ndi mankhwala ophera tizilombo.
Malo okhala m'madzi (mafamu a nsomba) nthawi zambiri amatulutsa nayitrogeni ndi phosphorous wambiri, komanso zolimba zoyimitsidwa. Malo ena amagwiritsa ntchito mankhwala ndi mankhwala ophera tizilombo omwe angakhalepo m'madzi oipa.

Zomera zopangira mkaka zimatulutsa zowononga wamba (BOD, SS).
Kupha ndi kukonza nyama kumatulutsa zinyalala zochokera kumadzi amthupi, monga magazi ndi m'matumbo. Zowononga zomwe zimapangidwa ndi BOD, SS, coliform, mafuta, organic nitrogen, ndi ammonia.

Chakudya chogulitsidwa chimapanga zinyalala zophikidwa, zomwe nthawi zambiri zimakhala ndi zinthu zachilengedwe zokhala ndi zomera komanso zimatha kukhala ndi mchere, zokometsera, zopaka utoto ndi ma asidi kapena maziko. Pakhoza kukhalanso mafuta ochuluka, mafuta ndi mafuta (" FOG ") omwe ali okwanira amatha kutseketsa ngalande. Mizinda ina imafuna malo odyera ndi okonza zakudya kuti agwiritse ntchito zoletsa mafuta ndikuwongolera kasamalidwe ka FOG m'mayendedwe otayira.

Ntchito zokonza zakudya monga kuyeretsa mbewu, kusamalira zinthu, kuthira mabotolo ndi kuyeretsa zinthu zimatulutsa madzi oipa. Malo ambiri opangira zakudya amafunikira chithandizo chapamalopo madzi otayira asanayambe kugwiritsidwa ntchito pamtunda kapena kutayidwa munjira yamadzi kapena ngalande. Kuchuluka koyimitsidwa kolimba kwa tinthu ting'onoting'ono kumatha kukulitsa BOD ndipo kumatha kupangitsa kuti achulukitse zimbudzi. Sedimentation, zowonetsera ngati mphero, kapena kusefera kwa mizere yozungulira (microsieving) ndi njira zomwe zimagwiritsidwa ntchito pochepetsa katundu wa zolimba zomwe zaimitsidwa zisanatulutsidwe. Cationic high-efficiency mafuta-water separator amagwiritsidwanso ntchito nthawi zambiri muzakudya zamafuta azimbudzi zopangira mafuta (zolekanitsa zamadzi zokhala ndi mafuta anionic kapena tinthu tating'ono ta zinyalala kapena madzi oyipa, kaya agwiritsidwa ntchito okha kapena ndi inorganic coagulant pawiri, akhoza kukwaniritsa mofulumira, ogwira kulekana kapena kuyeretsa zolinga madzi High dzuwa ndi olekanitsa madzi ali synergistic kwenikweni, akhoza imathandizira flocculation liwiro, kuchepetsa mtengo wogwiritsa ntchito zinthu).
