Ugutyulo lwasesibhedlele lubhekisa kugutyulo oluveliswa zizibhedlele oluqulethe iintsholongwane ezibangela iintsholongwane, iintsimbi ezinzima, izibulali-ntsholongwane, izinyibilikisi zendalo, iiasidi, iialkali, kunye neradioactivity.Ineempawu zongcoliseko lwesithuba, usulelo olubukhali, kunye nosulelo olufihlakeleyo.Ngaphandle konyango olusebenzayo, inokuba yindlela ebalulekileyo yokusasazeka kwezifo kwaye ingcolise kakhulu imo engqongileyo.Ngoko ke, ukwakhiwa kwe ukucocwa kwamanzi amdakaisityaloezibhedlele iye yaba sisitshixo sokusombulula le ngxaki.
1.Ukuqokelelwa kwelindle esibhedlele kunye nonyango lwangaphambili
Le projekthi yamkela inkqubo yogutyulo lwasekhaya kunye nenkqubo yemibhobho yokuhamba kwamanzi emvula, ehambelanayo nenkqubo yokuhanjiswa kwamanzi ezidolophini.Ugutyulo lwamanzi amdaka ezonyango kunye nogutyulo lwasekhaya kwindawo yesibhedlele ziqokelelwa ngombhobho wombhobho wothungelwano, zilungiswe kwangaphambili zizixhobo zokucocwa kogutyulo lwamanzi amdaka asasazekileyo (itanki yeseptic, isahluli se-oyile, netanki yeseptic kunye netanki yokubulala iintsholongwane kwangaphambili enikezelwe kugutyulo lweewadi ezosulelayo) indawo yesibhedlele, kwaye emva koko ikhutshwe kwisikhululo sokunyanga ilindle kwindawo yesibhedlele ukuze unyango.Emva kokuhlangabezana nomgangatho wokukhutshelwa koMgangatho wokuLahlwa kweziNgcolisi zaManzi kumaZiko oNyango, akhutshelwa kwindawo yokucocwa kogutyulo olusezidolophini ngothungelwano lwemibhobho yogutyulo lwasezidolophini.
Inkcazo yeyunithi yokusetyenzwa engundoqo yeukucocwa kwamanzi amdakaisityalo
① Iqula legridi lixhotyiswe ngemigangatho emibini yeegridi ezirhabaxa kunye nezicolekileyo, kunye nesithuba se-30 mm phakathi kweegridi ezirhabaxa kunye ne-10 mm phakathi kweegridi ezilungileyo.Thinta amasuntswana amakhulu ezinto ezinqunyanyisiweyo kunye nezinto ezithambileyo ezidityanisiweyo (ezifana namalaphu ephepha, amalaphu, okanye iintsalela zokutya) ukukhusela impompo yamanzi kunye neeyunithi zokusetyenzwa ezilandelayo.Xa ubeka, i-grating kufuneka ifakwe kwi-angle ye-60 ° ukuya kumgca othe tyaba wendlela yokuhamba kwamanzi ukuze kube lula ukukhutshwa kweentsalela ezithintelweyo.Ukuthintela ukuchithwa kwemibhobho kunye nokusasazwa kwezinto ezithintelweyo, uyilo kufuneka lugcine umlinganiselo wokuhamba kwamanzi amdaka phambi nasemva kokugalela phakathi kwe-0.6 m/s kunye ne-1.0 m/s.Izinto ezithintelwe yi-grating kufuneka zihlanjululwe nge-disinfected ngexesha lokususwa ngenxa yobukho benani elikhulu le-pathogens.
② Iqula elilawulayo
Ubume bombhobho wokuhambisa amanzi esibhedlele bumisela umgangatho ongalinganiyo wamanzi angenayo asuka kwisikhululo sogutyulo.Ngoko ke, itanki yokulawula imiselwe ukuba i-homogenize umgangatho kunye nobuninzi be-lindle kunye nokunciphisa impembelelo yemithwalo yempembelelo kwiiyunithi zonyango ezilandelayo.Ngexesha elifanayo, misela umbhobho wokugqithisa ingozi kwidama lengozi.Isixhobo sokungenisa umoya sifakwe kwitanki elawulayo ukuthintela ukunyibilika kwamasuntswana amisiweyo kunye nokuphucula ukubola kwamanzi amdaka.
③ Ichibi le-hypoxic aerobic
I-Anoxic aerobic tank yinkqubo engundoqo yokucoca ilindle.Inzuzo yayo kukuba ngaphezu kokuthotywa kwezinto ezingcolileyo eziphilayo, nayo inomsebenzi othile wokususwa kwe-nitrogen kunye ne-phosphorus.Inkqubo ye-A / O idibanisa icandelo langaphambili le-anaerobic kunye necandelo le-aerobic elingasemva kwi-series, kunye ne-A section DO engadluli kwi-0.2 mg / L kunye ne-O icandelo DO = 2 mg / L-4 mg / L.
Kwinqanaba le-anoxic, ibhaktheriya ye-heterotrophic i-hydrolyze ungcoliseko olumisiweyo olufana nesitashi, iifibers, iicarbohydrates, kunye ne-soluble organic matter kwi-lindle ibe yi-organic acids, ebangela ukuba i-macromolecular organic matter ibole ibe yi-molecule encinci yezinto eziphilayo.I-organic matter enganyibilikiyo iguqulwa ibe yi-soluble organic matter.Xa ezi mveliso ze-anaerobic hydrolysis zingena kwitanki ye-aerobic kunyango lwe-aerobic, ukubola kwe-biodegradability ye-lindle kuyaphuculwa kunye nokusebenza kakuhle kwe-oksijini kuphuculwe.
Kwicandelo le-anoxic, ibhaktheriya ye-heterotrophic i-ammonifies ezingcolileyo ezifana neprotheni kunye namafutha (N kwi-organic chain okanye i-amino acid kwi-amino acid) ukukhulula i-ammonia (NH3, NH4 +).Ngaphantsi kweemeko ezaneleyo zokubonelela nge-oksijeni, i-nitrification yebhaktheriya ye-autotrophic i-oxidizes NH3-N (NH4 +) kwi-NO3 -, kwaye ibuyela kwi-pool A ngokusebenzisa ulawulo lwe-reflux.Ngaphantsi kweemeko ezinobungozi, i-denitrification ye-heterotrophic bacteria iyanciphisa i-NO3 - kwi-nitrogen ye-molecular (N2) ukugqiba umjikelo we-C, N, kunye ne-O kwi-ecology kwaye ibone unyango olungenabungozi.
④ Itanki yokubulala iintsholongwane
Amanzi amdaka okucoca angena kwitanki yoqhagamshelwano yokubulala iintsholongwane ukuze kugcinwe ixesha elithile loqhagamshelwano phakathi kogutyulo kunye nesibulali-ntsholongwane, siqinisekisa ukuba isibulali-ntsholongwane sibulala iintsholongwane emanzini.Amanzi amdaka alahlwa kuthungelwano lwemibhobho kamasipala.Ngokutsho "kweMigangatho yokukhutshwa kwamanzi angcolileyo kwiZiko lezoNyango", ixesha lokuqhagamshelana nogutyulo oluvela kwizibhedlele zesifo esosulelayo akufanele libe ngaphantsi kweeyure ze-1.5, kwaye ixesha lokuqhagamshelana nogutyulo oluvela kwizibhedlele ezibanzi akufanele libe ngaphantsi kweyure eyi-1.0.
