Sezvo kusvibisa Bhizinesi rekudzora, iro rakanyanya kukosha basa rekurima kurapa kurapa ndiko kuona kuti fungidziro inosangana nemitemo yacho. Nekudaro, neyekuwedzera kuwanda zviyero uye nehasha revanoongorora zvakatipoteredza, yakaunza kudzvanywa kukuru kumuchengeti wekurapa kurapwa. Zviri chaizvo kuoma uye zvakaoma kuti mvura isabude.
Zvinoenderana nekuona kwemunyori, iko kukonzera kwakaoma kwekusvika kune iyo mvura yekubvisa mwero ndeyekuti pane kazhinji madenderedzwa matatu edenderedzwa muzvirimwa zvemunyika yangu.
Yekutanga inzvimbo inotyisa yeyakaderera sludge chiitiko (MLVSS / MLSS) uye yakakwira sludge kusungwa; Iyo yechipiri ndiyo inotyisa denderedzwa yeiyo yakakura huwandu hwesposphorus kubvisa makemikari akashandiswa, iyo yakanyanya kutsvedza; Chetatu ndechekureba kweshoko rekurapa rekurapa

Iyo inotyisa denderedzwa yeyakaderera sludge chiitiko uye yakakwira sludge constention
Muzvinafundo Wang Hongchen akagadzira kutsvagisa pa 467 Sewage zvinomera. Ngatitarisei data yeiyo sludge chiitiko uye sludge consturation: Pakati pezvidyarwa zvechiremba 467, 61
Iyo Sludge Constentration ye 2/3 yeiyo Sewage Kurapa Zvirimwa zvinopfuura 4000 MG / L, iyo Sludge Convertration yeChinyorwa chekurapa zvinopfuura 6000 mg / l,
Ndeipi mhedzisiro yemamiriro ekunze (yakaderera sludge chiitiko, yakakwira sludge constention)? Kunyangwe isu takaona zvinyorwa zvakawanda zvehunyanzvi zvinoongorora chokwadi, asi nenzira yakapfava, pane imwe mhedzisiro, kureva kuti, iyo inobuda mvura inopfuura mwero.
Izvi zvinogona kutsanangurwa kubva pane zviviri zvikamu. Kune rimwe divi, mushure mekushungurudzika kwakakwirira kwakakwira, kuitira kuti udzivise kushandurwa, kunokosha kuwedzera kuhurongwa. Kuwedzera huwandu hwesurasation hakuzowedzera kushandiswa kwesimba, asi zvakare wedzera chikamu chebhiriological. Kuwedzera kwekunyungudutswa kweokisijeni kuchabvisa carbon sosi inodiwa pakudengenyeka, iyo inozokanganisa zvakananga kudengenyeka uye phosphorus kubvisa maitiro ezvinyorwa, zvichikonzera kuwandisa n uye P.
Kune rimwe divi, iyo yakakwira sludgege inosimuka interface yekukwira, uye sludge ichirasika zviri nyore neyekuita sedimentation tangi, iyo ichavhara iyo yepamberi yekurapa yekurapa kana kukonzera iyo fungidziro yeiyo uye ss yekupfuura mwero.
Mushure mekutaura nezvemhedzisiro yacho, ngatitaurei nezve nei zvidyarwa zvizhinji zvine dambudziko rekudzikira soludge basa uye rakanyanya kutsvedza sludge.
Muchokwadi, chikonzero cheiyo yakakwira sludge yekuvhara ndiyo yakaderera sludge chiitiko. Nekuti iyo sludge basa rakaderera, kuitira kuti uvandudze kurapwa, iyo sludge yekuvhara inofanira kuwedzerwa. Iyo yakadzika sludge chiitiko chinokonzerwa nenyaya yekuti mvura ine simba ine huwandu hwakawanda hwejecha, iyo inopinda muBiology kurapwa unit uye inounganidza zvishoma nezvishoma, iyo inokanganisa chiitiko chehutachiona.
Kune yakawanda slag nejecha mumvura inouya. Imwe ndeyekuti kurambana kweiyo grille murombo zvakanyanya, uye imwe ndeyekuti kanopfuura kupfuura 90% yezvirimwa zvekurapa mune yangu nyika haina kuvaka matangi epakati.
Vamwe vanhu vangabvunza kuti, nei usingavake tangi rekutanga remhepo? Izvi ndezve pombi network. Pane matambudziko akadai sekusanzwisisika, kubatana kwakasanganiswa, uye kushayikwa kwepombi munzvimbo yangu. Nekuda kweizvozvo, iyo yemvura ine simba yemvura yegungwa kazhinji ine maitiro matatu: High Inorganic solid solid (INS), yakaderera cod, LADL CO / N RATIO.
Kuvhiringidzika kwesorganic solids mumvura ine simba yakakwirira, ndiko kuti, iyo jecha zvemukati zvakakwirira. Pakutanga, iyo yekutanga tangi yedhorobha inogona kuderedza zvimwe zvinhu zvisingaiti
Mukupedzisira kuongorora, zvakaderera sludge basa renhaka ye "zvinomera zvinorema uye mambure emwenje".
Isu tataura kuti yakakwirira sludge soludration uye yakaderera chiitiko ichaendesa kuwandisa n uye p mune effluent. Panguva ino, matanho ekupindura ezvirimwa zvakawanda zvekusanzika ndezvekuwedzera carbon zvinyorwa uye inorganic anofamba. Nekudaro, kuwedzera kwehuwandu hwekunze kwecarbon zvinyorwa zvichatungamira kune imwezve kuwedzera kwekushandiswa kwesimba, zvichikonzera kuwanda kwekusanzwisisika, kuenderera mberi kwekudzikisira kwechiitiko cheshuwa, kugadzira denderedzwa rakaipa.

Denderedzwa rinotyisa umo iyo yakakura huwandu hwePhosphorus kubvisa makemikari anoshandiswa, iyo yakakura iyo sludge kugadzirwa.
Iko kushandiswa kwe phosphorus kubvisa makemikari akawedzera iyo sludge kugadzirwa ne20% kusvika 30%, kana zvimwe.
Dambudziko rekushamwaridzana rave riri kunetseka kukuru kwezvirimwa zvekurapa kwemakore mazhinji, kunyanya nekuti hapana nzira yekubuda nayo sludge, kana nzira yekubuda haina kugadzikana. .
Izvi zvinotungamira kuchiitiko chezera rakanyanyoka, zvichikonzera munyarwa wekunyura kwekukwegura, uye kunyange zvakanyanya kusarongeka kwakadai sekutsvedza.
Iyo yakawedzerwa sludge ine hutano husina kunaka. Nekurasikirwa kwekuzadzwa kubva kune yechipiri sedimentation tank, iyo yepamberi yekurapa yunivhesiti yakavharwa, maitiro ekurapa akaderedzwa, uye huwandu hwemvura inodzokera shure.
Kuwedzera kwehuwandu hwemashure kwemvura kunotungamira kumhedzisiro miviri, imwe ndeyekuderedza kurapwa kweiyo yekutanga biochemical chikamu chikamu.
Mari yakakura yekumashure inodzoserwa kune iyo tangi yeganda, iyo inoderedza iyo chaiyo yekuchengetedza nguva yeiyo chimiro uye inoderedza kurapwa kwekurapa kwekurapa kwechipiri;
Yechipiri ndeyekuenderera mberi kuderedza iyo yekugadzirisa mhedzisiro yeiyo yakadzika yekugadzirisa chikamu.
Nekuti huwandu hukuru hwemvura yekudzosera kumashure hunofanirwa kudzoserwa kune yepamusoro kurapa kwehurongwa hwekurapa system, chiyero chekupedzisira chakawedzera uye chaicho filtation yekuwedzera yakaderedzwa.
Iko kurapwa kwakazara kurapwa kunova murombo, izvo zvinogona kukonzera iyo yakazara phosphorus uye cod mune iyo effluent yekupfuura chiyero. Kuti udzivise kudarika chiyero, chirimwa chekusona chinowedzera kushandiswa kwe phosphorus kubvisa vamiriri, izvo zvichawedzera kuwedzera huwandu hwekutsvedza.
mudenderedzwa rinotyisa.

Denderedzwa rinotyisa renguva refu-term
Kurapa kweSewage kunoenderana kwete chete kuvanhu, asiwo pamidziyo.
Sewage michina yanga ichirwira mumutsara wekumberi kwemvura yekurapa kwenguva yakareba. Kana zvisingawanzo kugadziriswa, matambudziko anozoitika munguva pfupi. Nekudaro, kazhinji, mashura emidziyo haigone kugadziriswa, nekuti kamwe chete mimwe michina inomira, iyo yekubuda kwemvura inogona kupfuura chiyero. Pasi pehurongwa hwezuva nezuva faindi, munhu wese haakwanise.
Pakati pezvibodzwa 467 zvehondo dzekurapa dzinoongororwa naProfesa Wang Hongchen, zvikamu zviviri muzvitatu zvine hydraulic mutoro wakakura kupfuura 80%, zvimedu zvechitatu, zvirimwa zvekurapa zvakakura kupfuura zana nemakumi mashanu muzana.
Kana iyo hydraulic mutakuri mwero wakakura kupfuura 80%, kunze kwezvirimwa zvakakura zvekurapa hazvigone kuvhara mwero, uye hapana mvura yemabhureki yevaridzikekete uye sekondari tangi. Midziyo yepazasi inogona chete kuve yakanyarara zvachose kana kutsiviwa kana ichidururwa.
Ndozviti, dzinenge 2/3 dzezvirimwa zvekusanzika hazvigone kugadzirisa zvishandiso pamidziyo yekuona kuti iyo effluent inosangana nemwero.
Sekureva kwaProfessor Wang Hongchen's Rongchen, makore evateresi kazhinji makore 4-6, asi 1/4 yezvidyarwa zvekusanwa hazvina kuita kuti varidzike pamakore matanhatu. Madhaka madhaka, ayo anoda kudururwa uye akagadziridzwa, kazhinji haagadziriswe gore rese kutenderera.
Midziyo yacho yanga ichimhanya nechirwere kwenguva yakareba, uye kugona kwemvura kuri kuramba kuchiwedzera. Kuti tiregedze kudzvinyirira kweanobuda mvura, hapana nzira yekumisa kuti igadziriswe. Mune denderedzwa rakadaro, pachagara paine nzira yekurapa yekurapa iyo ichasangana nedonhe.

Nyora pakupedzisira
Mushure mekudzivirirwa kwezvakatipoteredza kwakatangwa semagariro emunharaunda yangu yenyika, minda yemvura, gasi, ivhu uye rimwe rekusvibisa, pakati pemunda wekurapa wekurapa kungave mutungamiri. Levelfffford
Uye ikozvino, inguva yekugadzirira zvikanganiso.
