Mbuli kkampani iilanganya busofwaazi, mulimo mupati wabusena bwakusofwaazya tombe ngwakubona kuti tombe lilazuzikizya zyeelelo. Nokuba boobo, akaambo kakuyuma kwamilawu yakugwisya tombe alimwi abukali bwabasikulanga-langa zyakukwabilila busena, kwaleta buyumuyumu bupati bwakubeleka kucibaka cakusalazya tombe. Ncobeni cili mukuyuma kapati kugwisya maanzi.
Kweelana akulangisisya kwamulembi, kaambo keni-keni kakapa kuti kube buyumuyumu bwakusika aawo mpokugolela maanzi nkakuti kuli zintu zyotatwe zitali kabotu mumaanda aakusowela tombe muchisi changu.
Chakusanguna nchintu chibi chakubula bulongo (MLVSS/MLSS) akuvwula kwabulongo; chabili nchintu chibi chakuti mweelwe wamakemikalu aakugwisya phosphorus nuuvwula, mpawo bulongo bulazwa; chatatu ninzila yakugwisya tombe lyachiindi chilamfu. Ikubeleka loko, zibelesyo tazikonzyi kubambululwa pe, kakuli malwazi mwaka woonse, eezi zipa kuti kube kucheya kwanguzu zyakusalazya tombe.

Muzinguluko mubyaabi wakubeleka kwabulongo busyoonto antoomwe akuvwula kwabulongo
Mufundisi Wang Hongchen wakachita buvwuntauzi aatala amaanda aakusowela tombe aali 467. Atubone data yakubeleka kwabulongo abunji bwabulongo: Akati kamasena aaya aali 467, 61% yamasena aakusanzya tombe ajisi MLVSS/MLSS munsi aa 0.5, aali 30% yamaanda aasalazya tombe alijisi MLVSS/MLSS munsi aa 0.4.
Bulongo bwa 2/3 bwamasena aakusanzya tombe bulainda 4000 mg/L, bulongo bwa 1/3 bwamasena aakusanzya tombe bulainda 6000 mg/L, mpawo bunji bwabulongo bwamasena aasalazya tombe aali 20 bulainda 10000 mg/L.
Ino nzintu nzi zikonzya kuchitika akaambo kabukkale buli atala aawa (kubeleka kwabulongo buniini, bunji bwabulongo)? Nikuba kuti twabona zibalo zyiingi zyabusongo zilanga-langa kasimpe, pesi mumajwi maubauba, kuli mpindu yomwe, nkokuti, maanzi azwa aayinda aawo mpaayelede.
Eezi zilakonzya kupandululwa kuzwa mumbazu zyobile. Kulubazu lumwi, nikwakamana bunji bwabulongo, kuchitila kutabilila bulongo, kuyandika kuyungizya muya. Kuyungizya mweelwe wamuwo takukonzyi buyo kuyungizya kubelesya manguzu, pesi akuyungizya alubono lwazintu zipona. Kuyungizya kwa oxygen iitegwa dissolved oxygen kuyoobweza kaboni iiyandika kuti kube kugwisya muuya, ooko kuyoojatikizya kugwisya muuya akugwisya phosphorus mumubili, mpawo kuyoopa kuti kube N a P zinji.
Kulubazu lumwi, bunji bwabulongo bupa kuti busena buli akati kamatope amaanzi buyungizigwe, mpawo bulongo bulafwambaana kusweeka antoomwe amaanzi aazwa mutanki lyabili lyakuyobweda bulongo, eezyo zikonzya kusinkila busena bwakusanzya busumpukide naakuti kupa kuti maanzi azwa mu COD a SS aindilile aawo mpobeelede.
Nitwakamana kwaambuula aatala azintu zikonzya kuchitika, atwaambe aatala akuti nkamboonzi maanda manji aakusowela tombe ngaajisi penzi lyakucheya kwabulongo antoomwe akuvwula kwabulongo.
Mubunike, kaambo kakuvwula kwabulongo nkakuti bulongo tabubeleki kabotu pe. Nkaambo kakuti mulimo wa bulongo uli munsi, kuchitila kuti kube kuyaambele kwakusilikwa, bunji bwa bulongo bweelede kuyungizigwa. Ikucheya kwabulongo buli akaambo kakuti maanzi ajisi bulongo bunji, oobo bunjila mubusena bwakusanzya zintu zipona mpawo bulabungika asyoonto-asyoonto, oobo bupa kuti tuzunda tutabeleki kabotu.
Kuli bulongo bunji amusenga mumaanzi aaboola. Chimwi nchakuti kujata kwa grille nchintu chibi loko, mpawo achimwi nchakuti kwiinda 90% yamasena aakusanzya tombe muchisi changu taakwe naakayaka matanki aakusaanguna.
Bamwi bantu balakonzya kubuzya kuti, nkamboonzi ncotutayaki tanki lyakuyobweda bulongo? Eezi zili aatala anzila yamapaipi. Kuli mapenzi aalimbuli kubula kuswaangana, kuswaangana kusanganizidwe, akubula kuswaangana mumapaipi muchisi changu. Mukujana mpindu, bubotu bwamaanzi mumaanda aakusowela tombe buli abube botatwe: bunji bwazintu zitakwe buumi (ISS), COD nsyoonto, C/N nsyoonto.
Bunji bwazintu zitakwe buumi mumaanzi aazwa kulisumpukide, nkokuti, musenga ulisumpukide. Kumatalikilo, nkapu yakusaanguna yakuyobola maanzi yakali kukonzya kucesya zintu zimwi zitaponi, pesi nkaambo kakuti COD yamaanzi aakali kunjila njiiniini, bunji bwamaanda aakusowela tombe taakwe naakayaka nkapu yakusaanguna yakuyobola maanzi.
Mukulanga-langa kwamamanino, bulongo butazungaani nchintu chizwa "kuzisyango zilemu antoomwe atunsabwe tutakatazyi pe".
Twaamba kuti bunji bwabulongo akubeleka kusyoonto kuyoopa kuti kube N a P zinji kapati mumaanzi azwa. Aachiindi eechi, nzila zyakusandula zyamaanda manji aakusowela tombe nkuyungizya zintu zipa kuti kube kaboni azintu zitakwe buumi. Nokuba boobo, kuyungizya mweelwe mupati wa kaboni uuzwa anze kuyoopa kuti kube kuyungizigwa kwakubelesya manguzu, mpawo kuyungizya mweelwe mupati wa flocculant kuyoopa kuti kube bulongo bunji bwamakemikalu, eezi ziyoopa kuti bulongo buvwule akucheya kwabulongo, mpawo bupa kuti kube muzyunguluko mubyaabi.

Muzinguluko mubyaabi oomo mweelwe wamakemikalu aakugwisya phosphorus nuubelesyegwa, mpawo bulongo bulavwula.
Kubelesya makemikalu aakugwisya phosphorus kwayungizya kupanga bulongo a 20% kusika ku 30%, naa kwiinda waawo.
Penzi lyabulongo lyakali penzi pati lyamaanda aakusanzya tombe kwamyaka myiingi, ikapati nkaambo taakwe nzila yakuzwa yabulongo, naakuti nzila yakuzwa tiikkalikene pe. .
Eezi zipa kuti bulongo buzumanane kuchembaala, mpawo eezi zipa kuti bulongo buchembaala, antoomwe azintu zitali kabotu mbuli kuvwula kwabulongo.
Bulongo bwakayungizyigwa tabuli kabotu pe. Aawo kusweekelwa kwamaanzi kuzwa muchibbeeke chabili, bbazu lyakusanzya lilajalwa, mulimo wakusanzya ulacheya, mpawo mweelwe wamaanzi aakusanzya musule ulatanta.
Kuyungizya kwamaanzi aakusanzya musule kuyoopa kuti kube mapenzi obile, yomwe nkucesya busilisi bwachibeela cha biochemical chakayinda.
Meenda manji aakusanzya musule alajokezyegwa muchibbeeke chakuyungizya muya, eecho chicheesya chiindi chakujatilila kwamaanzi muchiyaka mpawo chicheesya busilisi bwabili;
Cabili nchakuyungizya kuchesya mulimo wakubamba zyintu zyaansi.
Nkaambo kakuti maanzi manji aakusanzya musule ayelede kupilusyigwa kunzila yakusefa iisumpukide, mweelwe wakusefa ulayungizyigwa mpawo nguzu zyakusefa zilacheya.
Kusilika koonse kwaba kubi, ooko kukonzya kupa kuti phosphorus yoonse antoomwe a COD mumaanzi azwa mumaanzi ziinde aawo mpozigolela. Kuti kutabi kwiinda aawo mpokugolela, busena bwakusowela tombe buyooyungizya kubelesya misamu iigwisya phosphorus, eezyo ziyooyungizya bulongo.
mumulongo mubyaabi.

Muzinguluko mubyaabi wakuzula kwachiindi chilamfu kwamaanda aakusowela tombe akucheya kwanguzu zyakusalazya tombe
Kusalazya tombe takuyeeme abantu luzutu pe, pesi azibelesyo.
Zibelesyo zyakusowela tombe zyakali kulwana mumulimo wakusanzya maanzi kwachiindi chilamfu. Kuti tiikwabambululwa chiindi choonse, mapenzi alakonzya kuchitika muchiindi chifwiifwi. Nokuba boobo, muziindi zyiingi, zibelesyo zyakusowela tombe tazikonzyi kubambululwa pe, nkaambo zibelesyo zimwi noziima, maanzi azwa alakonzya kwiinda zyeelelo. Mubweendelezi bwakubbadela mali abuzuba, boonse tabakonzyi kuula.
Akati kamasena aakusanzya tombe aali 467 aakavwuntauzyigwa aMufundisi Wang Hongchen, aali zyuulu zyobile akati kazyotatwe aayo ajisi nguzu zyamaanzi ziinda ku 80%, aali chisela chimwi chazyotatwe chiinda ku 120%, mpawo masena aakusalazya tombe ali musanu aayinda ku 150%.
Eelyo mweelwe wa hydraulic load rate nuwiinda 80%, kunze lyamasena mapati aakusalazya tombe, masena aasalazya tombe taalikonzyi kujala maanzi kuti abambululwe nkaambo kakuti maanzi azwa asika aawo mpaayelede, alimwi taakwe maanzi aakubelesya aakubelesya muya alimwi azibelesyo zyakuyoya tombe. Zibelesyo zyaansi zilakonzya buyo kubambululwa naakuti kuchinchwa kuti zyamana maanzi.
Nkokuti, aali 2/3 yamaanda aakusowela tombe taakonzyi kubambulula zibelesyo nkaambo kakusinizya kuti tombe lilazuzikizya zyeelelo.
Kweelana abuvwuntauzi bwa Professor Wang Hongchen, buumi bwama aerators kanjikanji buli myaka iili 4-6, asi 1/4 yamaanda aakusowela tombe tanaakachita mulimo wakubamba muya muma aerators kwamyaka iili 6. Chibelesyo chakugwisya bulongo, chilikuyandika kugwisigwa akubambululwa, kanjikanji tachibambululwi mwaka woonse.
Zibelesyo zyakali kubeleka akuchiswa kwachiindi chilamfu, mpawo nguzu zyakusalazya maanzi zilikuyaabubija. Kuti ukonzye kuliyumya kukusinikizyigwa kwakuzwa kwamaanzi, taakwe nzila yakuyiimika kuti ibambululwe. Mubukkale bubyaabi buliboobu, kuyooba nzila yakusalazya tombe iikonzya kuwa.

lemba kumamanino
Kukwabililwa kwabusena nikwakabikkwa mbuli nzila mpati yachisi changu, milimo yamaanzi, muya, zintu ziyumu, bulongo azimwi zisofweede yakasumpuka chakufwambaana, akati kazeezi mbunga yakusalazya tombe ilakonzya kwaambwa kuti njiisololela. Kakwiina zyeelelo zizulide, kubeleka kwabusena bwakusowela tombe kwawida mumapenzi, mpawo penzi lyamapaipi abulongo bwaba tumpenda tobile tupati twamulimo wakusofwaazya tombe muchisi changu.
Mpawo lino, nceciindi chakubambulula tumpenda.
