Kayayyakin masana'antun abinci suna da nau'ikan kayayyaki, akwai kayayyakin madara, abin sha, kayan shakatawa, sarrafa kayayyakin gona da sauransu, kayan aiki, hanyoyin aiki, sikelin da sauransu suna da bambanci sosai. Ruwan sharar gida yana canzawa sosai tare da yanayi, tsarin samarwa, ruwan sharar gida yana ƙunshe da adadin abubuwan halitta (furotin, starch, mai), masu lalacewa, amma ba su ƙunshi abubuwa masu cutarwa ba. Hanyoyin sarrafa su sun fi dacewa da ilimin halitta, kuma a lokaci guda sun haɗa hanyoyin da sauran abubuwa. A ƙasa akwai misali na ruwan sharar gida na starch don bayyana tsarin sarrafawa.

2.Waste ruwa fitarwa yanayin da kuma sarrafawa bukatun

Babban matattarar ruwan sharar gida na wani masana'antar starch shine 400m3 / d; CODcr5500 mg / L, BOD3400mg / L, ρ (SS) 1-15g / L, PH darajar ne 4, ruwa zafin jiki ne 45-55.C， Low mataki na kwayoyin ruwa fitarwa ne 100m3 / d; CODcr 100 mg / L, BOD450 mg / L, darajar PH ita ce 6-7, zafin jiki na ruwa 20-22. Tsarin yana amfani da tsarin anaerobic (UASB + AF) - tuntuɓar oxidation - aeroflot. Anaerobic sassa na COD cirewa kudi ne 85%, BOD cirewa kudi ne 90%, lamba oxidation tsari COD cirewa kudi ne 76%, BOD cirewa kudi ne 77%

3. Tsarin aiki

High mayar da hankali na sharar ruwa → daidaitawa tafkin → UASB + AF → tuntuɓar oxide tafkin → Air floating na'urar → isa ga daidaitaccen fitarwa

4. Abubuwa

1, amfani da hanyar iska na iya cire mai daga ruwa da kuma haɗari fitarwa daga babban matakan sunadarai da man fetur a cikin ruwa.

2, Amfani da AF zai iya sa manyan kwayoyin halitta su rushe zuwa ƙananan kwayoyin halitta masu sauƙin lalacewa da kuma cire yawan kwayoyin halitta.
