Njengeshishini elilawulayo longcoliseko, owona msebenzi ubalulekileyo wesityalo sonyango se-loge kukuqinisekisa ukuba amanzi amdaka ahlangabezana nemigangatho. Nangona kunjalo, kunye nemigangatho yokuphumelela engqongqo engqongqo kwaye inobundlobongela abahloli abaKhusela abaKhuselo kwiNdalo, izise uxinzelelo olukhulu lokusebenza kwesityalo se-sebage. Kuyaba nzima kwaye kube nzima kakhulu ukufumana amanzi.
Ngokutsho kombhali, unobangela ngqo wobunzima ekufikeleleni kumgangatho wokukhulula amanzi kukuba kukho ngokubanzi isangqa esithathu kwizityalo zelizwe lethu.
Eyokuqala yisangqa esikhohlakeleyo somsebenzi we-sludge ophantsi (MLVS / MLSS) kunye ne-sludge ephezulu; Okwesibini yisangqa esikhohlakeleyo sexabiso le-phosphorus lokukhupha iphospirus esetyenzisiweyo, kokuphathwa kwe-slulgere eqhelekileyo; Okwesithathu luhlobo lwexesha elide lokuhambisa amanzi amdaka, izixhobo azinakugqithiswa, zibaleka nezifo unyaka wonke, ezikhokelela kwisangqa esikhohlakeleyo sokuncitshiswa konyango.

Isangqa esikhohlakeleyo somsebenzi we-sludge ophantsi kunye ne-sludge ephezulu
Unjingalwazi wang Hongchen wenze uphando kwizityalo ze-467. Makhe siqwalasele idatha yomsebenzi we-sludge kunye noxinzelelo: phakathi kwezi zityalo ze-467, izityalo ezingama-667 ze-SEWAR SIRSS inee-MLVS / MLSS izityalo ezingaphantsi kwe-MLVS / MLSSS ngaphantsi kwe-0.4.
I-sludge gxini ye-2/3 yezityalo zonyango lwe-SEWAR / L, i-Sludge yoNyango yeSityalo idlula i-6000 yezityalo ze-SEWARE / L, kwaye izityalo zonyango lwe-Squage zingaphezulu kwe-10000 mg / l.
Zithini iziphumo zale mibandela ingentla (umsebenzi ophantsi we-sludge, uxinzelelo oluphezulu)? Nangona sibone amanqaku amaninzi obuchwephesha ahlalutya inyaniso, kodwa ngamagama alula, kukho isiphumo esinye, oko kukuthi, ukukhutshwa kwamanzi kudlula kumgangatho.
Oku kunokuchazwa kwiinkalo ezimbini. Kwelinye icala, emva kokuba uxinzelelo lwe-sludge liphezulu, ukwenzela ukuthintela i-Slusciation, kuyimfuneko ukonyusa ukungcungcuthekiswa. Ukonyusa inani le-aeration aliyi kunyusa ukusetyenziswa kwamandla, kodwa kwandise icandelo lebhayoloji. Ukunyuka kweoksijini echithiweyo kuyakuthwaza umthombo wekhabhoni ofunekayo ukuze kulungiswe isibophelelo, esiya kuchaphazela ngokuthe ngqo isiphumo sokususwa kwe-phosphoruri kunye nenkqubo ye-phosphoruor yenkqubo yendalo, ekhokelela kwi-P.
Kwelinye icala, uxinzelelo oluphezulu lwe-slue wenza ukunyuka kodaka, kwaye i-sludge ilahlekile ngokulula kunye namanzi amdaka akwitanki yendlela yesekondari, eya kuthi ithintele iyunithi yonyango okanye ibangele ukuba i-ECHE DOD kunye ne-SS igqithe umgangatho.
Emva kokuthetha malunga nemiphumo, masithethe malunga nokuba kutheni izityalo ezihamba ngenqanawa zinengxaki yomsebenzi we-sludge ophantsi kunye noxinzelelo oluphezulu.
Ngapha koko, isizathu sokuba i-sludge ephezulu yeyona nto iphantsi. Ngenxa yokuba umsebenzi we-SLUDE uphantsi, ukwenzela ukuphucula isiphumo sonyango, uxinzelelo lwe-Sludge kufuneka lonyuswe. Umsebenzi we-sludge ophantsi ngenxa yokuba amanzi anempembelelo equlethe inani elikhulu lesanti ye-SLAG, efaka iyunithi yonyango lwebhayoloji kwaye iquka umsebenzi we-microorganisms.
Kukho i-slag enkulu kunye nesanti kumanzi angenayo. Enye yeyokuba isiphumo sokukhutshwa kwe-grille sihlwempuzeke kakhulu, kwaye enye yeyona nto ingaphezulu kwe-90% yezityalo zonyango lwethayile kwilizwe lam azange zakha iitanki ze-sediment.
Abanye abantu banokubuza, kutheni bengakhe itanki yokuphakamisa? Oku malunga nenethiwekhi yombhobho. Kukho iingxaki ezinje ngokwazi gwenxa, uqhagamshelo oluxubeneyo, kunye nonxibelelwano olushiyekileyo kwinethiwekhi ye-pile kwilizwe lam. Ngenxa yoko, umgangatho wamanzi ophengwe sisityalo se-sewage ngokubanzi uneempawu ezintathu: I-InOrganic yoxinzelelo eqinileyo (i-ISS), i-COD ephantsi, i-C / n I-C / N Inqanaba le-C / N
Ukuxinezeleka kwezinyibilikisi zamanzi aphantsi kwefuthe phezulu, oko kukuthi, umxholo wesanti uphakame kakhulu. Ekuqaleni, itanki eyintloko ye-sediment inokunciphisa izinto ezinamanzi, kodwa ngenxa yokuba i-CoD yamanzi empembelelo iphantsi, izityalo ezixhaphakileyo ziphantsi, uninzi lwezityalo ze-sewage al nje azikhanga itanki ye-sediment.
Kuhlalutyo lokugqibela, umsebenzi ophantsi weSludge lilifa le "izityalo ezinzima kunye neminatha yokukhanya".
Sitshilo ukuba uxinzelelo lwe-sludge kunye nomsebenzi ophantsi luya kukhokelela kwi-N kunye ne-P kwi-Ekrekranve. Ngeli xesha, amanyathelo okuphendula kwezityalo ezininzi zokuntywila zongeza imithombo ye-carbon kunye ne-inorgalic scordcys. Nangona kunjalo, ukongezwa kwenani lemithombo yekhabhoni yangaphandle kuya kukhokelela kulo lonke unyuso lwamandla, ngelixa ukongezwa kwesixa esikhulu se-slucture siya kuvelisa inani le-sludge, okukhokelela ekunciphiseni isangqa se-sludge, senza isangqa esikhohlakeleyo.

Isangqa esikhohlakeleyo apho inani elikhulu kangakanani i-phosphorus yokukhupha i-phosphorus esetyenzisiweyo, kokukhulu kwemveliso ye-SLUM.
Ukusetyenziswa kweekhemikhali ze-phosphorus khupha imichiza yonyuse ukuveliswa kwe-SLUGE nge-20% ukuya kwi-30%, okanye nangaphezulu.
Ingxaki ye-sludge ibe yeyona nto iphambili kwizityalo zonyango zokuhlambela iminyaka emininzi, ikakhulu kuba akukho ndlela yokuphuma kwesahlulo, okanye indlela yokuphuma engazinzanga. .
Oku kukhokelela ekufundisweni kwesahluko se-Sludge, okukhokelela kwi-phenomenon yokwaluphala kwe-sludge, kunye nokungaqhelekanga ngakumbi njengokubulala.
I-sludge eyandisiweyo inesinga lokuzisebenzisa okubi. Ngokulahleka kwamanzi amdaka avela kwitanki yendawo yesibini, iZiko loNyango loNyango eliPhambili livaliwe, isiphumo sonyango incitshisiwe, kwaye inani lokunyuka kwamanzi okunyuka kwamanzi.
Ukunyuka kwenani lamanzi akusemva kuya kukhokelela kwiziphumo ezibini, enye kukunciphisa isiphumo sonyango lwecandelo le-bichemical yangaphambili.
Isixa esikhulu samanzi asemva sibuyiselwa kwitanki yokugcina i-throuling, enciphisa i-hydraulic ixesha lokugcina i-hydraulic, inciphisa isiphumo sonyango lonyango lwesibini;
Okwesibini kukuqhubela phambili ukunciphisa isiphumo senkqubo yokusebenza kubunzulu bendawo yokusebenza.
Kuba isixa esikhulu samanzi okuselwa ngaphezulu kufuneka sibuyiselwe kwinkqubo yokuphela konyango esiqinileyo, izinga elililo liyanda kwaye eyona nto ihlafunayo incitshisiwe.
Iziphumo zonyango zizonke ziyahlwempuza, ezinokubangela iphosphorus iyonke kwaye i-COD kumanzi amdaka agqithe umgangatho. Ukwenzela ukuthintela ngaphezulu komgangatho, isityalo se-logerey siya kwandisa ukusetyenziswa kweearhente zokususa phospirus, eziya kuthi zikwandisa ubungakanani be-sludge.
kwisangqa esikhohlakeleyo.

Isangqa esikhohlakeleyo sexesha elide lokutsala isityalo se-genage kunye nokuncitshiswa komgangatho wonyango
Unyango lwe-logerege luxhomekeke kuphela ebantwini, kodwa nakwizixhobo.
Isixhobo sokuntywila silwe kumgca wangaphambili wonyango lwamanzi ixesha elide. Ukuba ayilungiswa rhoqo, iingxaki ziya kwenzeka kungekudala okanye kamva. Nangona kunjalo, kwiimeko ezininzi, izixhobo zokubiyela ezingenakulungiswa, kuba nje ukuba isixhobo esithile siyekile, ukukhutshwa kwamanzi kunokwenzeka ukuba kube ngaphezulu komgangatho. Phantsi kwenkqubo yeziselo zemihla ngemihla, wonke umntu akanakukwazi ukuyifumana.
Phakathi kwezityalo zonyango ezingama-467 zedolophu zangaphantsi koProfesa wang Hongchen, malunga nesibini kwisithathu sinezigaba zomthwalo ezinama-80%, malunga ne-50% yezityalo, kunye nezityalo ezi-5 zokunyanga ezi-5.
Xa inqanaba lomthwalo we-hydraulic lingaphezulu kwe-80%, ngaphandle kwezityalo ezikhulu zokunyanga eziphezulu, izityalo zonyango ngokubanzi azikwazi ukuzivalela amanzi ogcino kwi-aeffint ifikelela kwimigangatho efihliweyo kunye ne-suckup yetanki kunye nekratshi. Izixhobo ezisezantsi zinokugqithiselwa ngokupheleleyo okanye zitshintshwe xa ikhutshiwe.
Oko kukuthi, malunga ne-2/3 yezityalo ezixhaphakileyo azinakulungisa izixhobo kwi-proses yokuqinisekisa ukuba amanzi amdaka ahlangabezana nomgangatho.
Ngokutsho koProfesa wang Hongchen, ixesha lokuphila kwabantu, kodwa i-1/4 yezityalo eziluhlaza azenzeki ukugcinwa kolondolozo lwangaphezulu kwe-Eerators kangangesithuba seminyaka emi-6. I-DUD CRAPERPER, ekufuneka ikhutshiwe kwaye ilungiswe, ayilungiswa rhoqo ngonyaka.
Ezi zixhobo ziye zabaleka kunye nokugula ixesha elide, kwaye umthamo wonyango lwamanzi uya usiba mandundu ngakumbi. Ukwenzela ukumelana noxinzelelo lwevenkile yamanzi, akukho ndlela yokuyinqanda ukuze igcinwe. Kwisangqa esikhohlakeleyo, kuya kuhlala kukho inkqubo yokunyanga yokunyanga eza kujongana nayo.

Bhala ekugqibeleni
Emva kokukhuselwa kwendalo esingqongileyo njengemigaqo-nkqubo yelizwe lethu elisisiseko, amabala amanzi, igesi, oqinileyo, umhlaba kunye nolunye unyango longcoliseko luye lwathi yinkokeli. Inqanaba elinganeleyo, ukusebenza kwesityalo se-loger siwele kwingxaki, kwaye ingxaki yenethiwekhi ye-piholine kunye ne-sludge iye yaba ziintsilelo ezimbini eziphambili zeli lizwe lokunyanga umthwalo welizwe.
Kwaye ngoku, lixesha lokuba wenze iintsilelo.
Ixesha lasemva: Feb-23 ukuya kwi-2322
