A. aiki ka'idar na iska biofilter

Air Biofilters (BAF - Biological Aerated Filters) an ci gaba shi ne bisa ga al'ada biofilter tafkin, high load biofilter tafkin, biofilter hasumiya, biocontact oxidation hanyar da sauran biofilm hanyar, da aka sani da na uku tsara biofilter tafkin. A cikin ci gaban tsari, cikakken amfani da ruwa sarrafawa tuntuɓar oxidation hanyar da kuma ruwa samar da sauri tacewa tafkin zane ra'ayoyin, wato, bukatar iska, high tacewa gudun, kama dakatarwa, bukatar lokaci-lokaci backwashing da sauran halaye. Ka'idar tsari ita ce cika wasu ƙananan ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin Lokacin da ruwa ya gudana ta hanyar, amfani da high rabo farfajiyar yanki na tacewa kawo da high taro biofilm oxidation lalacewa ikon tsabtace ruwa da sauri, wannan ne biooxidation lalacewa tsari; A lokaci guda, lokacin da ruwan datti ke gudana, kayan tacewa suna da matsin lamba, amfani da ƙananan siffofin ƙwayoyin matata da tasirin biocoagulation na biofilm, don tsare abubuwan dakatarwa a cikin ruwan datti, kuma tabbatar da cewa biofilm da ya fadi ba zai tashi tare da ruwa ba, wannan shine tasirin tsarewa; Bayan wani lokaci na aiki, saboda karuwar asarar ruwa, ana buƙatar sake wanke tafkin tacewa don sakin dakatarwa da sabunta biofilm, wannan tsari ne na sake wanke.

Gabaɗaya, iska biofilter yana da wadannan halaye:
(1) Yi amfani da granular cikawa a matsayin biological carriers, kamar abubuwan da aka yi amfani da su, kwartas yashi, aiki carbon, da dai sauransu.
(2) bambanci daga gaba ɗaya biofilter da biofilter hasumiya, a cire BOD, ammonia nitrogen bukatar iska.
(3) High karfin ruwa kaya, high girman kaya da kuma high biofilm aiki.
(4) Tare da aikin biyu na lalacewar oxidation da tsare SS, ba a buƙatar sanya tafkin ruwa na biyu ba bayan rukunin sarrafawa na halitta.
(5) Ana buƙatar yin wanka a kai a kai, tsaftace SS da aka tsare a cikin tace da sabunta biofilm.

Babban amfanin Air Bio Filter Tsarin
(1) Air halitta tacewa tafkin ne na uku tsara halitta tacewa tafkin, da amfani da kananan particle size, mafi girma fiye da farfajiyar yanki, muhimmanci inganta halitta matattarar; Amfani da hanyar haɗin gwiwar maganin halitta da tacewa don ceton tafkin ruwa na biyu; Yin amfani da hanyar anti-rinse, kawar da yiwuwar toshewa, yayin da yake inganta aikin biofilm; Yin amfani da biofilm da bioflocculation haɗin gwiwa, a lokaci guda wasa amfanin biofilm da aiki mud hanyar. Babban inganta ingancin ruwa na fitarwa, aiki da kaya.
Air biofilter yana da tasirin lalacewa da tacewar oxidation, don haka za a iya samun ingancin ruwa mai girma, wanda zai iya cimma ƙa'idodin ingancin ruwa na sake amfani. Ga ruwan sharar gida na masana'antu, ko da a cikin yanayin da ba shi da ƙarfin sinadarai, tasirin sarrafa dakin tacewar halittu na iska ya fi kyau fiye da tsari na gaba ɗaya, saboda sarrafa dakin tacewar halittu na iska ba kawai ya dogara ne akan oxidation na halittu ba, har ma akwai mahimmanci da tasirin tacewar halittu, saboda girman ƙwayoyin da za a iya cirewa yana da girma, kuma za a iya cirewa daga wasu kayan da ba su da ƙarfin sinadarai. Saboda kwarewar cikawa da kanta da tasirin flocculation na farfajiyar biofilm, yana safitarwa SS ne kasa, yawanci ba fiye da 10mg / l,fitar da ruwa sosai m da kuma m; Saboda ci gaba da kwarara, an sabunta biofilm yadda ya kamata, yana nunawa a matsayin biofilm mai ƙaranci (yawanci kimanin 110 micron), aiki mai girma. Babban aikin biofilm ba kawai yana bayyana a cikin ɓangaren oxidation, lalacewa ba, amma kuma yana bayyana a matsayin flocculation na halitta, tasirin absorption. Ga wasu abubuwa masu wuya da za su lalace, za a iya sha su, a riƙe su a cikin tafkin, kuma a cire su.
Air Bio tace yana da babban aiki nauyi: karfin ruwa nauyi, girman nauyi sosai mafi girma fiye da gargajiya tsabtace ruwa aiki tsariRuwaKarfin kaya zai iya kai 6-8m3 / m2h; Girman kaya zai iya kai 3-6kgBOD5 / m3d), da kuma zama lokaci mai ɗan gajeren (daya mataki zai iya kai 0.5-0.66h).
(2) karamin yankin da aka rufe, ma'aikatar zuba jari ta kayan aiki. Ba tare da dakin ruwan sama na biyu ba bayan dakin tacewar halittu na iska, zai iya ceton yankin da zuba jarin dakin ruwan sama na biyu.Air Bio tace dauki yankin kawai 1/10-1/5 na yau da kullun tsari. High aiki kaya, da kuma lokacin zama na gajeren lokaci, saboda haka pool karfin karami, da kuma kayan aiki zuba jari tanadi akalla 20-30% fiye da al'ada tsari.
(3) low aiki kudi. Gas samar da makamashi amfani da kashi mai yawa a cikin aiki kudin duk aerobic bioprocessing, da iska biofilter tsari oxygen watsa amfani da inganci ne mai girma, da iska karami, da kuma samar da oxygen makamashi amfani da low.Amfani da oxygen inganci zai iya zuwa 20-30%. Injiniya aiki ya nuna cewa iska yawa ne na gargajiya aiki lakar hanyar 1/20, da oxidation rami 1/6, da SBR1/4-1/3,Ana adana kuɗin aiki sosai. Air bio tace ruwa mutum asara karami, da sauran mud yawa da sauki sarrafawa, da kuma kulawa kadan yawa, wannan zai tabbatar da aiki kudin low.
(4) Mai ƙarfi mai juriya da ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin. Kwarewar aiki ta nuna cewa tashar halitta na iska na iya aiki a ƙarƙashin ɗan gajeren lokaci mai girma sau 2-3 na al'ada, yayin da ingancin ruwan fitarwa yana da ƙananan canji. Wannan bangare ya dogara da high rabo farfajiyar yankin tacewa, a lokacin da kara da organic load karuwa, biomass na tacewa farfajiyar iya sauri kara darajar; A gefe guda, ya dogara da ikon buffering na biofilter na gaba ɗaya. Bugu da ƙari, bioventilation tace da zarar hanging nasara, za a iya aiki a 6-10 ° C ruwa zafin jiki, kuma yana da mafi kyau aiki sakamako.
(5) Easy hanging film, fara da sauri. Air bio tace a kusan ruwa zafin jiki na 15 ℃, 2 zuwa 3 makonni za a iya kammala hanger tsari. A lokacin da ba a yi amfani da shi ba, za a iya kashe aiki, a lokacin da biofilm na matattarar farfajiyar ba ta mutu ba, maimakon haka a cikin nau'i na spores, da zarar an saukar da ruwa, za a iya dawo da al'ada a cikin ɗan gajeren lokaci. Wastewater zafin jiki ne game da 15 ℃, dakatar da aiki rabin wata (a cikin madaidaicin madaidaicin ruwa kuma ba tare da iska), bayan dawo da aiki, bayan kwanaki uku shi ne gaba daya dawo da al'ada. Wannan fasalin ya sa tashar halitta ta iska ta dace da sarrafa ruwa a wasu manyan yankuna masu canjin ruwa. A yankunan yawon shakatawa, yawan ruwan sharar gida ya shafi canje-canje na yanayi da yawan yawon shakatawa sosai, a lokacin da yawon shakatawa ke ƙasa da yanayi, za a iya kashe wani ɓangare na biofilters na iska don rage farashin aiki da ba a so ba, a lokacin da ake buƙata, za a iya dawo da ƙirar sarrafawa a cikin ɗan gajeren lokaci.
(6) Air Bio tace ta amfani da modular tsari, sauki daga baya canji, fadada. Akwai rashin amfani a cikin tsarin sarrafa ruwan datti na yanzu a cikin gida: Lokacin da aka ƙara yawan sarrafa ruwan datti, dole ne a gyara tsarin asali sosai, saboda babban dalilin shi ne cewa ba su da tsarin tsari. Air Bio tace cikakken modular, sosai m ga baya fadada da gyare-gyare, kawai bukatar kara yawan tace tafkin tare, ba tare da tasiri da akwai tsari aiki.
(7) Amfani da sarrafa kansa iko, sauki management. Air biofilter za a iya amfani da cikakken sarrafa kansa sarrafawa, management ne sosai sauki. A lokaci guda saboda tsarinsa ba shi da rikitarwa, don haka babu buƙatar kayan aikin sarrafa kansa masu rikitarwa, kuma babu buƙatar horo mai yawa na fasaha na ma'aikata.
(8) ba samar da wari, muhalli high quality. Ingancin muhalli na gida na yanzu mai tsabtace ruwa masana'antu gabaɗaya ba shi da kyau, wari ya yadu, ƙwayoyi da sauran kwayoyi da yawa, tashar halitta ta iska ba ta samar da wari ba, amfani da wannan tsarin na masana'antun ruwa mai tsabtace ruwa yana da ingancin muhalli mai girma.
