Madzi a m'chipatala amatanthawuza za zimbudzi zopangidwa ndi zipatala zomwe zimakhala ndi tizilombo toyambitsa matenda, zitsulo zolemera, mankhwala ophera tizilombo, organic solvents, acids, alkalis, ndi radioactivity.Ili ndi mawonekedwe a kuipitsidwa kwa malo, matenda owopsa, komanso matenda obisika.Popanda chithandizo chamankhwala, itha kukhala njira yofunika kwambiri yofalitsira matenda ndikuwononga kwambiri chilengedwe.Choncho, kumanga kwa kuchiza zimbudzichomeramzipatala wakhala chinsinsi kuthetsa vutoli.
1.Kutolere zimbudzi m'chipatala ndi kusamalidwa
Ntchitoyi imagwiritsa ntchito mapaipi amadzi am'nyumba ndi madzi amvula, omwe amagwirizana ndi njira zoyendetsera madzi m'mizinda.Zimbudzi zachipatala ndi zimbudzi zapakhomo m'dera lachipatala zimasonkhanitsidwa kudzera mumsewu wapaipi yamadzi, zomwe zimayendetsedwa ndi zida zam'madzi zomwe zimamwazikana (septic tank, separator mafuta, tank septic ndi tank pre disinfection yoperekedwa ku ngalande zama ward opatsirana) chipatala m'dera, ndiyeno kutulutsidwa kwa zimbudzi mankhwala siteshoni m'dera chipatala chithandizo.Pambuyo pokwaniritsa mulingo wotulutsa wa Water Pollutants Discharge Standard for Medical Institutions, amatulutsidwa m'malo oyeretsera zimbudzi zamatawuni kudzera pa mapaipi amadzi am'tawuni.
Main processing unit kufotokoza kwakuchiza zimbudzichomera
① Chitsime cha gridi chimakhala ndi zigawo ziwiri zamagulu owoneka bwino komanso abwino, okhala ndi kusiyana kwa 30 mm pakati pa ma gridi owoneka bwino ndi 10 mm pakati pa ma gridi abwino.Kudula particles lalikulu la inaimitsidwa nkhani ndi finely agglomerated zofewa nkhani (monga mapepala nyenyeswa, nsanza, kapena zotsalira chakudya) kuteteza mpope madzi ndi wotsatira mayunitsi processing.Poyika, grating iyenera kupendekeka pamakona a 60 ° mpaka pamzere wopingasa wa njira yoyendetsera madzi kuti zithandizire kuchotsa zotsalira zotsekeka.Pofuna kupewa kusungunuka kwa mapaipi ndi kubalalika kwa zinthu zotsekeka, kapangidwe kake kayenera kusunga kuchuluka kwa zimbudzi zisanayambe kapena zikatha kugwetsa pakati pa 0.6 m/s ndi 1.0 m/s.Zinthu zomwe zimatsekeredwa ndi grating ziyenera kutetezedwa ndi tizilombo toyambitsa matenda panthawi yochotsa chifukwa cha kupezeka kwa tizilombo toyambitsa matenda.
② Dziwe loyang'anira
iye chikhalidwe cha chipatala ngalande amatsimikiza khalidwe m'njira ya madzi obwera kuchokera zimbudzi mankhwala siteshoni.Choncho, thanki yoyang'anira imakhazikitsidwa kuti iwonetsetse ubwino ndi kuchuluka kwa zimbudzi ndi kuchepetsa zotsatira za katundu pazigawo zotsatila.Panthawi imodzimodziyo, khazikitsani chitoliro chodutsa ngozi ku dziwe langozi.Zipangizo zamagetsi zimayikidwa mu thanki yowongolera kuti zisawonongeke kuti tinthu tating'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono tiwonongeke.
③ Hypoxic aerobic dziwe
Anoxic aerobic tank ndiye njira yayikulu yochizira zimbudzi.Ubwino wake ndi woti kuwonjezera pakuwononga zowononga zachilengedwe, imakhalanso ndi ntchito inayake ya kuchotsa nayitrogeni ndi phosphorous.Njira ya A / O imagwirizanitsa gawo la kutsogolo kwa anaerobic ndi gawo lakumbuyo la aerobic mu mndandanda, ndi gawo A DO osapitirira 0.2 mg / L ndi O gawo DO = 2 mg / L-4 mg / L.
Mu anoxic siteji, mabakiteriya heterotrophic hydrolyze inaimitsidwa zoipitsa monga wowuma, ulusi, chakudya, ndi zosungunuka organic zinthu mu zinyalala mu zidulo zidulo, kuchititsa macromolecular organic kanthu kuwola kukhala ang'onoang'ono molekyulu organic kanthu.Insoluble organic matter imasinthidwa kukhala zinthu zosungunuka.Pamene mankhwala a anaerobic hydrolysis kulowa mu thanki aerobic mankhwala aerobic, ndi biodegradability wa zimbudzi ndi bwino ndi dzuwa mpweya bwino.
Mu gawo la anoxic, mabakiteriya a heterotrophic ammonifies zowononga monga mapuloteni ndi mafuta (N pa organic chain kapena amino acid mu amino acid) kuti amasule ammonia (NH3, NH4 +).Pansi pamikhalidwe yokwanira yoperekera okosijeni, nitrification ya mabakiteriya a autotrophic oxidize NH3-N (NH4+) kupita ku NO3 -, ndikubwerera ku dziwe A kudzera mu reflux control.Pansi anoxic zinthu, ndi denitrification wa mabakiteriya heterotrophic amachepetsa NO3 - kuti maselo asafe (N2) kuti amalize mkombero wa C, N, ndi O mu zachilengedwe ndi kuzindikira chopanda vuto kuchimbudzi mankhwala.
④ thanki yophera tizilombo
Madzi osefa amalowa mu thanki yopha tizilombo kuti asunge nthawi yolumikizana pakati pa zinyalala ndi mankhwala ophera tizilombo, kuwonetsetsa kuti mankhwalawa amapha bwino mabakiteriya m'madzi.Madzi osefukira amatayidwa mu netiweki ya mapaipi a tauni.Malinga ndi "Water Pollutant Discharge Standards for Medical Institutions", nthawi yolumikizana ndi zimbudzi kuchokera kuzipatala za matenda opatsirana siyenera kukhala osachepera maola 1.5, ndipo nthawi yolumikizana ndi zimbudzi kuchokera kuzipatala zonse siziyenera kukhala zosakwana 1.0 ora.
