Kuumbwa kwesludge kwakaoma, kune zvakasiyana-siyana uye marudzi.Parizvino, nzira huru dzekurasa marara pasi rose imarara emarara, kupisa marara, kushandiswa kwezviwanikwa zvevhu, uye dzimwe nzira dzakakwana dzekurapa.Nzira dzinoverengeka dzekurasa dzine zvadzakanakira nekusiyana mukushandisa, pamwe nekukanganisa kwakati.Semuenzaniso, sludge landfill ichava nematambudziko akadai sekuoma kwemagetsi compaction, yakaoma filtrate kurapwa, uye yakakomba kunhuwa kusvibiswa;kupiswa kwedhaka kune matambudziko akadai sekushandiswa kwesimba rakawanda, kudhura kwakanyanya kwekurapa, uye kugadzirwa kweanokuvadza dioxin magasi;Iko kushandiswa kugadzirisa matambudziko akadai sekutenderera kwakareba uye nzvimbo yakakura.Pazere, kuzadzikiswa kwekusakuvadza kwematope, kudzikisira, kushandisa zviwanikwa, uye kugadzirisa kurapwa idambudziko remamiriro ekunze rinoda kuramba richigadziriswa uye kuvandudzwa.
Sludge aerobic composting tekinoroji:
Mumakore achangopfuura, sludge aerobic composting tekinoroji yakashandiswa pakurasa matope.Iyo isingakuvadzi, inoderedza vhoriyamu, uye inodzikamisa sludge yakazara yekurapa tekinoroji.Nekuda kwenzira dzayo dzakawanda dzemashandisirwo ezvigadzirwa zvakaviriswa (kushandiswa kwemasango emasango, kushandiswa kwenzvimbo, ivhu rekuvhara marara, nezvimwewo), mari shoma yekudyara uye mutengo wekushandisa, Ruzhinji rwekushandisa uye humwe hunhu hunobatikana zvakanyanya.Kune matatu akajairwa macompost process, anoti: stacking type, bin/trough type, uye reactor.Chinhu chakakosha ndechekuti nharaunda yemicrobial inoora uye inoshandura iyo organic zvinhu mumatope kuita kabhoni dioxide, mvura, inorganic matter, uye biological cell nyaya pasi pemamiriro akakodzera ehutano, hunyoro uye kufefetera, kuburitsa simba panguva imwe chete, nekuvandudza iyo yakasimba. tsvina muchidyiro.Humus, kunatsiridza sludge fetiraiza.
Zvinodiwa zvekutanga zve sludge composting:
Kune akawanda masosi edhaka, asi mamwe haana kukodzera semidziyo yekugadzira composting.Kutanga, zvinotevera zvinongedzo zvinoda kusangana:
1. Iyo inorema simbi yemukati haipfuure mwero;2. Inoora;3. The organic matter content haigoni kuva yakaderera, inodarika 40%.
Iyo tekinoroji nheyo yesludge composting:
Nheyo iyi ndiyo nzira yekunyorovesa kwemarara akasimba nekuita kwe aerobic microorganisms pasi pemamiriro eaerobic.Muchiitiko ichi, zvinhu zvinonyunguduka mumatope zvinotorwa zvakananga nema microorganisms kuburikidza nemasero emadziro uye masero membranes e microorganisms;chechipiri, iyo insoluble colloidal organic substances inoshambadzirwa kunze kwema microorganisms, yakasvibiswa muzvinhu zvinonyunguduka neextracellular enzymes inovanzwa ne microorganisms, uye yozopinzwa mumasero.Microorganisms dzinoita catabolism uye anabolism kuburikidza nehupenyu hwavo hwega metabolic zviitiko, oxidize chikamu cheiyo yakanyudzwa organic zvinhu muzviri nyore inorganic zvinhu, uye kuburitsa simba rinodiwa pamabasa ekukura kwebiological;gadzira chimwe chikamu cheorganic matter kuita zvinhu zvitsva zvemaserura, kuitira kuti Kukura uye kuberekana kwemicroorganism, kuburitsa zvimwe zvipenyu.
Hybrid preprocessing:
Rongedza saizi yechikamu, hunyoro, uye kabhoni-nitrogen reshiyo yechinhu, uye wedzera mabhakitiriya panguva imwe chete kukurudzira kufambira mberi nekukurumidza kwekuvirisa.
Kuvirisa kwekutanga (composting):
Bvisa zvinhu zvinoputika mumarara, uraya mazai eparasite uye pathogenic microorganisms, uye zadzisa chinangwa chekusakuvadza.Kana hunyoro hukaderedzwa, iyo organic matter inoora uye mineralized kuburitsa N, P, K, uye zvimwe zvinovaka muviri, uye panguva imwecheteyo, zvimiro zveiyo organic zvinhu zvinosunungurwa uye zvinopararira.
Kuvirisa kwechipiri (yakaora):
Iyo organic tsvina yakaoma mushure mekuviriswa kwecompost yekutanga isati yasvika pakukura uye inoda kuenderera mberi nekuvirisa kwechipiri, ndiko kuti, kuchembera.Chinangwa chekuchembera ndechekuwedzera kuora, kudzikamisa uye kuomesa yakasara macromolecular organic matter mu organic matter kuti isangane nezvinodiwa zveinotevera fetiraiza kugadzirwa.
