Kuita microbial kurapwa kwekusimuka kwekutanga kuisa huwandu hwekushanda kwecroiniki. Pollutants inogona kurapwa uye nekushandiswa zvakanyanya zvinobudirira, uye nekudaro maketani mazhinji ekudya anogona kuumbwa, achiumba chikafu-chekuyambuka chikafu chebhusaiti. Iyo yakanaka uye yakagadzikana exiological balance system inogona kusimbiswa kana huwandu hwakakodzera uye simba ratios dzinochengetwa pakati pematare emabhuruku. Kana imwe huwandu hwesungwa hunopinda iyi ecosystem, iyo organic Pollutants mairi haina kungocherwa uye yakanatswa. . kudzora outropotopu yemuviri wemvura.
1. Kurapwa kwemicrobial kwegungwaKunyanyabvisa organic Pollutants (Bod, cod zvinhu) muCollodal uye isina kunyungudika mamiriro muSangano, uye chiyero chekubvisa chinogona kusvika 90%, kuitira kuti organic Pollutants inogona kusangana neiyo discharge.
(1. Izvo zvinowanzo kureva chimwe chikamu chekushandisa zvinhu zviri nyore zvirimo zvine 1L yegungwa kana sampuli yemvura kuti iongororwe. Kana microorganisms oxidize uye oda iyo, iyo yakanyungudika oksijeni mumvura inopedzwa mumamiriyoni (iyo unit ndeye mg / l). Mamiriro ezvinhu ekuyera okusvirwa anowanzoonekwa pa 20 ° C kwemazuva mashanu nehusiku, saka chiratidzo bod5 chinowanzoshandiswa.
(2. (unit ndeye mg / l). Inowanzoshandiswa makemikari Oxidants are k2cr2o7 kana Kmno4. Pakati pavo, K2CR2O7 inowanzoshandiswa, uye cod yakayerwa inomiririrwa ne "COD CR".
2. Microbial yekurapa seage inogona kukamurwa kuita aerobic kurapwa system uye anaerobic kurapwa system zvinoenderana neiyo mamiriro eokisijeni mukurapa.
1. Aerobic kurapwa system
Pasi pemamiriro ezvinhu aErobic, Microorganisms adsorb organic zvine basa munharaunda, oxidize uye oda iyo muchinhu chisikwa, kuchenesa sewage, uye synthesize nyaya yemari panguva imwe chete. Mukuita kwekunatswa kwekunatswa, microorganisms kuvapo muchimiro chekushandurwa kwakasarudzika uye zvinhu zvikuru zve biofilm.
Iyi nzira ndiyo nzira yekubatwa biological yekurapa ine biofilm semuviri mukuru wekuzvinatsa. Biofilm ndeye mucous membrane yakasungirirwa pamusoro peiyo inotakura uye inonyanya kuumbwa nemabharikiti micelles. Basa reBiofilm rakafanana neiyo yeiyo yakagadziriswa sludge mune yakagadziriswa sludge maitiro, uye midziyo yayo microbial yakafananawo. Nheyo huru yekucheneswa kwekunyepedzera ndeyekushambidzika uye oxidative kuora kweiyo organic nyaya mune sewage neiyo biofilm yakabatanidzwa kune iyo inotakura inotakura. Maererano nemaitiro akasiyana ekuonana pakati nepakati nepakati uye mvura, iyo biofilm nzira inosanganisira nzira yebhizimusi uye iyo shongwe yetsiva yebhuruu nzira.
Pasi pemamiriro ezvinhu ezasi, nzira yekushandisa anaerobic bacteria (inosanganisira faeerobic bacteria) yekuita organic bawiyo muSangano zvakare inonzi anaerobic kujaya kana anaerobic filectation. Nekuti chigadzirwa chekufema chinobereka methane, chinonziwo methane fermentation. Iyi nzira haigone kungobvisa kusvibiswa kwezvakatipoteredza, asi zvakare kukudziridza bio-simba, saka vanhu vanoteerera zvakanyanya. Aaerobic Fermentation yeSewage inonyanya kuoma ecosystem, iyo inosanganisira akasiyana emapoka ezvipfuyo, imwe neimwe inoda kusiyana siyana uye mamiriro ezvinhu, achiumba ecosyx yakaomarara. Methane Fermentation inosanganisira matanho matatu: Liquefiction Stage, hydrogen kugadzirwa uye acetic acid yekugadzira nhanho uye methane kugadzirwa nhanho.
Sewage kurapwa kunogona kukamurwa kuita zvekutanga, sekondari uye kuseteriya kurapwa zvinoenderana neyero yekurapwa.
Kurapa kwekutanga: Zvinonyanya kubvisa zvakamiswa zvakasvibiswa zvakasvibiswa muSellutants muSuwage, uye mazhinji emhando dzekurapa dzinogona kungozadzisa zvinodiwa pakurapwa kwekurapwa kwekurapwa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapwa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa kwekurapa. Mushure mekurapa kwekurapa kwesangano, bod inogona kuwaniswa neanosvika makumi matatu muzana, iyo isingasviki mwero wechirango. Iyo yekutanga kurapwa ndeyekutanga kurapwa kwechipiri kurapwa.
Maitiro ekurapa ekurapa ari: Sangano remukati rakapfuura nepakati pegrid inosimudzwa neiyo sew Basa rekamuri rekunakisa kubvisa malorganic zvidimbu zvine hombe chaiyo gravity. Kazhinji inoshandiswa grit makamuri anofarira makamuri, akaomeswa grit makamuri, dole grit makamuri uye bhero-mhando grit makamuri.
Kurapa Sekondari: Zvinonyanya kubvisa colluidal uye yakanyungudutswa organic pollutants (bod, cod zvinhu) muSuege, uye chiyero chekubvisa chinogona kusvika 90%, kuitira kuti organic Pollutants inogona kusangana neyakawana mwero.
Iyo yechipiri kurapwa maitiro ndeyekuti: Mvura inoyerera ichibva kune yekutanga tangi inopinda mumidziyo yeBiology, ( Kubva pane zvekurapa zvekurapa zvinopinda zvechisimba tangi, uye fungidziro kubva kune yechipiri sedimentation tangi inodzingwa mushure mekurapwa kana kupinda kurapwa kwetertiary.
Kurapa kweTertiary: Kunyanya kubata neRefractor En organic zvinhu, sluluble inormac zvinhu zvakadai se nitrogen uye phosphorous inogona kutungamira
kusvika pakutenderera kwemuviri wemvura. Nzira dzaishandiswa dzinosanganisira biological deditrization uye coigerusus yekubvisa, coagoration sedimentation, yakagadziriswa carbon adsorption nzira, ion exchange nzira uye Electroosmosis yekuongorora maitiro.
Maitiro ekurapa ekurapa ari seinotevera: Chikamu cheSludge mune yechipiri Tangi inodzoserwa Tangi yeTank Mushure mekusvibiswa uye kuomesa michina, iyo sludge yakazoshandiswa.
Kunyangwe iri mutengi mutsva kana mutengi wekare, isu tinotenda mukugadzirwa kwakakosha kweAmbimoni Defirtia yekurapa neChina.
Marara emakemikari kurapwaChina Bactia Special Dhizaini, Buttial Water Creat Agent, semuvengi waakarairwa, mutsva, isu tanga tiri kutarisira zvinhu zvese zvekutsvagisa, dhizaini, kugadzira, kutengesa uye kugovera. Nekutsvagira nekukudziridza tekinoroji matsva, isu hatiteveri chete asi tungamira maFashoni indasitiri. Isu tinoteerera nokungwarira kumhinduro yevatengi uye tipe kutaurirana nekukurumidza. Iwe uchangodaro unonzwa hunyanzvi hwedu uye sevhisi yekuteerera.
