Kunyangwe kupfuya huku kwave kuwedzera kukurumbira muAfrica mumakore apfuura, chave chiri chiitiko chidiki.Mumakore mashoma apfuura, zvakadaro, rave danho rakakomba, nevazhinji vechidiki mabhizinesi vachinanga purofiti inoyevedza painopihwa.Huku dzehuku dzinodarika 5 000 dzave kuwanda asi danho rekuuchika kwaita kuti veruzhinji vazeye nenyaya yekuraswa kwemarara.Iyi nyaya, inofadza, inopawo mikana yakakosha.
Kugadzirwa kwakakura kwakaunza matambudziko mazhinji, kunyanya ane chekuita nekuraswa kwemarara.Mabhizinesi madiki haakwezve kutariswa kwakawanda kubva kune zviremera zvezvakatipoteredza asi mashandiro ebhizinesi ane nyaya dzezvakatipoteredza anodiwa kuti ateedzere iwo akafanana kuchengetedzwa kwemamiriro ekunze.
Sezvineiwo, dambudziko remarara emupfudze riri kupa varimi mukana wekugadzirisa dambudziko guru: kuwanikwa uye mutengo wemagetsi.Mune dzimwe nyika dzemuAfrica, maindasitiri mazhinji ari kunyunyuta nekudhura kwemagetsi uye vagari vemumaguta vakawanda vanoshandisa majenareta nekuti magetsi haavimbike.Kushandurwa kwendove yemarara kuva magetsi kuburikidza nekushandisa biodigester kwazova tarisiro inokwezva, uye varimi vazhinji vari kutendeukira kwairi.
Kushandurwa kwemarara emupfudze kuita magetsi kunopfuura bhonasi, nekuti magetsi chinhu chinoshomeka mune dzimwe nyika dzemuAfrica.Iyo biodigester iri nyore kubata, uye mutengo unonzwisisika, kunyanya kana iwe uchitarisa mabhenefiti enguva refu
Pamusoro pekugadzirwa kwemagetsi ebiogas, zvakadaro, tsvina yebiogas, inogadzirwa neprojekti yebiodigester, ichasvibisa nharaunda zvakananga nekuda kwehuwandu hwayo, huwandu hweammonia nitrogen uye organic matter, uye mutengo wekufambisa, kurapwa uye kushandiswa. high.Nhau dzakanaka ndedzekuti marara ebiogas anobva kubiodigester ane kukosha kwekudzokorodza zviri nani, saka tinoita sei kushandisa zvizere tsvina yebiogas?
Mhinduro ndeye biogas fetireza.Biogas tsvina ine marudzi maviri: imwe imvura (biogas slurry), inoverengera 88% yehuwandu.Chechipiri, zvakasara zvakasimba (biogas residue), inoverengera inenge 12% yehuwandu.Mushure mekunge marara ebiodigester abviswa, anofanirwa kunayiswa kwekanguva (secondary fermentation) kuita kuti yakasimba uye mvura iparadzanise zvakasikwa.Yakasimba - mvura inoparadzanisainogona zvakare kushandiswa kupatsanura mvura uye yakasimba zvisaririra biogas tsvina.Biogas slurry ine zvinovaka muviri zvakaita senitrogen inowanikwa, phosphorus uye potassium, pamwe nekutsvaga zvinhu zvakaita se zinc ne iron.Maererano nekutsunga, iyo biogas slurry ine yakazara nitrogen 0.062% ~ 0.11%, ammonium nitrogen 200 ~ 600 mg/kg, inowanikwa phosphorus 20 ~ 90 mg/kg, inowanikwa potassium 400 ~ 1100 mg/kg.Nekuda kwekukurumidza kuita kwayo, chiyero chekushandisa chekudya chakanyanya, uye chinogona kukurumidza kunyudzwa nezvirimwa, imhando yemhando yepamusoro yakawanda inokurumidza kuita musanganiswa fetereza.Yakasimba biogas yakasara fetireza, zvinovaka muviri uye biogas slurry zvakangofanana, zvine 30% ~ 50% organic matter, 0.8% ~ 1.5% nitrogen, 0.4% ~ 0.6% phosphorus, 0.6% ~ 1.2% potassium, asiwo yakapfuma muhumic asidhi inopfuura 11%.Humic acid inogona kusimudzira kuumbwa kweivhu aggregate dhizaini, kusimudzira kuchengetedza kubereka kwevhu uye kukanganisa, kuvandudza ivhu remuviri uye kemikari zvimiro, ivhu remelioration mhedzisiro iri pachena.Hunhu hwebiogas residue fetireza yakafanana neyakajairwa organic fetireza, inova yeanonoka kuita fetireza uye ine yakanyanya kunaka kwenguva refu.
Tekinoroji yekugadzira yekushandisa biogasslurrykugadzira fetereza yemvura
Iyo biogas slurry inopombwa mumuchina wekuberekesa utachiona hwekubvisa hwema nekuvirisa, uye ipapo iyo yakaviriswa yebiogas slurry inoparadzaniswa kuburikidza nechakasimba-chimvura chekuparadzanisa mudziyo.Iyo yekuparadzanisa mvura inopomberwa mukati me elemental complexing reactor uye mamwe makemikari fetiraiza zvinhu anowedzerwa kune yakaoma kuita.Iyo yakaoma reaction liquid inoputirwa mukati mekuparadzanisa uye kunaya system kuti ibvise iyo isinganyungudika tsvina.Iyo yekuparadzanisa mvura inopombwa mu elemental chelating kettle, uye zvinhu zvekuteedzera zvinodiwa nezvirimwa zvinowedzerwa kune chelating reaction.Mushure mekuita kwapera, chelate fluid ichapombwa mutangi rapera kuti ipedze kubhodha nekurongedza.
Tekinoroji yekugadzira yekushandisa zvisaririra zvebiogas kugadzira organic fetereza
Iyo yakaparadzaniswa yebiogas inosara yakasanganiswa nemashanga, fetiraiza yekeke nezvimwe zvinhu zvakapwanyika kusvika pakukura, uye hunyoro hwakagadziriswa kusvika 50% -60%, uye C / N reshiyo yakagadziridzwa kusvika 25:1.Mabhakitiriya ekuvirisa anowedzerwa mune yakasanganiswa zvinhu, uye ipapo zvinhu zvinogadzirwa kuita murwi wecompost, hupamhi hwemurwi hausi pasi pe2 metres, kureba hakusi pasi pe1 metres, kureba hakuna kuganhurirwa, uye tangi. aerobic fermentation process inogona kushandiswa zvakare.Ngwarira kushanduka kwemwando uye tembiricha panguva yekuvirisa kuchengetedza aeration mumurwi.Muchikamu chekutanga chekuvirisa, unyoro hahufaniri kunge huri pasi pe40%, kana zvisina kudaro hazvibatsiri kukura uye kubereka kwema microorganisms, uye unyoro haufaniri kunge wakanyanyisa, izvo zvinokanganisa mhepo.Kana tembiricha yemurwi ikakwira kusvika 70 ℃, iyo compost turner muchinainofanira kushandiswa kushandura murwi kusvikira waora zvachose.
Kugadziriswa kwakadzika kwe organic fertilizer
Mushure mekuvirisa zvinhu uye kukura, unogona kushandisaorganic fertilizer kugadzira michinanokuda kwekugadzirisa kwakadzika.Chekutanga, inogadzikwa kuita powdery organic fertilizer.Thenzira yekugadzira powdery organic fertilizeriri nyore.Kutanga, zvinhu zvinopwanyika, uye ipapo tsvina iri muzvinyorwa inoongororwa nekushandisa ascreening machine, uye pakupedzisira kurongedza kunogona kupedzwa.Asi processing kupindagranular organic fertilizer, granular organic production process yakanyanya kuomarara, chinhu chekutanga kupwanya, kuvhara kunze tsvina, zvinhu zvegranulation, uyezve zvimedu zve.kuomesa, kutonhora, coating, uye pakupedzisira kupedzakurongedza.Iwo maviri maitiro ekugadzira ane zvawo zvakanakira uye zvazvakaipira, iyo poda organic fertiliza yekugadzira maitiro iri nyore, mari yacho idiki, inokodzera ichangobva kuvhurwa organic fekitori, iyogranular organic fertilizer kugadzira maitiroyakaoma, iyo mari yakakwira, asi iyo granular organic fetireza haisi nyore kuunganidza, iko kushandiswa kuri nyore, kukosha kwehupfumi kwakakwira.
