Metsi a litšila a temo ea liphoofolo

(1) Tšilafalo e ngata ea lintho tse phelang
Lintho tse tiileng tse emisitsoeng, lintho tse phelang, le ammonia nitrogen content metsing a litšila a temo ea liphoofolo a batla a le holimo, 'me a tiileng le mokelikeli a kopantsoe, a na le mojaro o phahameng oa ts'ilafalo. Tlhokahalo ea oksijene ea biochemical ea matsatsi a mahlano (BOD5) e lipakeng tsa 600 le 7000 mg/L, 'me tlhokeho ea oksijene ea lik'hemik'hale (COD) e ka fihla ho 13000 ho isa ho 17000 mg/L.
Naetrojene, phosphorus, le lijo tse setseng ka har'a mantle li lebisa habonolo keketsehong e kholo ea bongata ba mokelikeli sebakeng se seng le se seng sa naha. Sena se baka bongata bo feteletseng ba limatlafatsi mobung mme se sitisa botsitso ba tikoloho ea naha.
Haeba naetrojene le phosphorus tsena li tšeloa ka metsing, ho na le tšekamelo ea ho baka eutrophication ea 'mele oa metsi, kahoo e lebisa ho se leka-lekaneng ha ho aroloa ha mefuta ea lintho tse phelang metsing, ka kholo e atileng ea mofuta o le mong, e sitisang phallo ea metsi. taba le matla a tsamaiso, 'me butle-butle li etsa hore tikoloho eohle ea metsing e timele.
Haeba naetrojene ka sebōpeho sa nitrate ka metsing e jeoa ke batho, e tla baka tšenyo bophelong ba batho. Tšenyo ena e boetse e kenyelletsa lintho tse ling tse silafatsang likhoerekhoere, lithethefatsi tse setseng tsa bongaka ba liphoofolo, le likokoana-hloko tsa pathogenic.
(2) Merero ea ho hloekisa metsi a litšila nakong ea temo ea liphoofolo, nako ea ho tsoa ha metsi a litšila e batla e tsepamisitsoe, 'me boima ba tšusumetso bo boholo.
Metsi a litšila a hlahisoang ke temo ea liphoofolo ka kakaretso a ntšoa ka nako e le 'ngoe ka nako e behiloeng, 'me nako le nako ho na le litšila tse ngata tse tsoang metsing a litšila a tsoang. Ka nako e 'ngoe, palo ea metsi a litšila e fokotsehile haholo. Sena se beha litlhoko tse phahameng holim'a matla a taolo ea bophahamo ba metsi a litšila le matla a ho hanyetsa mojaro a sistimi ea ho hloekisa metsi. Ho hlophisoa ha litšila metsing a litšila ho rarahane ebile ho na le palo e kholo ea libaktheria tsa pathogenic; likarolo tse silafatsang tsa metsi a litšila tsa temo ea mehlape ha li akarelletse feela lintho tse bakang eutrophication ea 'mele oa metsi joalo ka nitrogen le phosphorus empa hape le likarolo tse boima tsa tšepe tse kang koporo, mercury, arsenic le selenium, mme ka nako e ts'oanang ho na le palo e kholo ea masala a lithethefatsi tsa bongaka ba liphoofolo tse kang lihomone, lithibela-mafu le li-antioxidants ka metsing a litšila. Libaktheria tsa pathogenic tse arolelanoang pakeng tsa batho le liphoofolo, tse kang Escherichia coli, anthrax, brucellosis, le lefuba, li ngata metsing a litšila.
(3) Mererong ea ho hloekisa metsi a litšila ka temo ea liphoofolo, metsi a litšila a tsoakoa le a tiileng le a mokelikeli, 'me motsoako oa lintho tse tiileng tse emisitsoeng o phahame, le viscosity e kholo; mantle le masala a fepa a nang le palo e kholo ea lintho tse phelang li ntšoa ka har'a metsi a litšila hammoho le metsi a phallang, e leng se lebisang ho palo e batlang e le e phahameng ea lintho tse tiileng tse emisitsoeng ka metsi a litšila a temo ea liphoofolo le viscosity e kholo ea motsoako o tiileng le oa mokelikeli. Lintho tse thata tse emisitsoeng joalo ka masala a mantle le mesaletsa le tsona li na le tšekamelo ea ho koala liphaephe tsa setsi sa kalafo, ho eketsa bothata ba kalafo.
(4) Biodegradability e ntle, tekanyo e phahameng ea BOD / COD
Karo-karolelano ea BOD/COD ea litšila metsing a litšila a temo ea liphoofolo e batla e le 0.45:1, 'me tekanyo ea B:C metsing a litšila e kopana le maemo a ho senyeha ha limela, ka mokhoa o motle oa ho senyeha ha lintho.

1. Khanyetso ea ho Thibela: Li-diffuser tsa li-disc li tlameha ho etsoa hore li se ke tsa koala ka lebaka la boemo bo phahameng ba lintho tse tiileng tse fanyehiloeng metsing a litšila a liphoofolo. Bongata bo boholo ba pore kapa meralo ea ho itlhoekisa e kanna ea hlokahala ho boloka moea o sebetsa hantle.
2. Ho tšoarella nako e telele: Thepa ea diffuser e lokela ho ba matla 'me e khone ho mamella maemo a mabifi a metsi a litšila a mehlape, joalo ka bongata ba ammonia le boteng ba likhase tse senyang (mohlala, hydrogen sulfide). Lisebelisoa tse kang EPDM kapa silicone li atisa ho sebelisoa bakeng sa morero ona.
3. Katleho ea Phetisetso ea Oksijene: Kaha litsamaiso tsa moea tsa bioloji li itšetlehile ka phetisetso e sebetsang ea oksijene, li-diffuser li lokela ho khona ho fana ka lipululana tse ntle ho matlafatsa ho qhibiliha ha oksijene, esita le boteng ba metsoako ea lintho tse phelang le lintho tse tiileng. Sena se tiisa hore libaktheria tsa aerobic li ka senya lintho tse phelang hantle.
4. Boiketlo ba Tlhokomelo: Ka lebaka la tikoloho e thata ea ts'ebetso, li-diffuser li tlameha ho ba bonolo ho li hloekisa le ho li boloka ho netefatsa ts'ebetso e tsitsitseng. Ho fihlella le moralo o thusang ho hloekisa khafetsa ho ka thusa ho boloka ts'ebetso ea nako e telele.
5. Matla a Matla a Matla: Kaha metsi a litšila a temo ea liphoofolo a ka hloka nako e telele ea aeration, li-diffuser tsa disc li lokela ho sebetsa hantle, li fokotsa litšenyehelo tsa ts'ebetso ha li ntse li netefatsa hore mekhoa ea likokoana-hloko e tšehetsoa ka ho lekaneng.
