The johkasou ndi yaing'ono m'nyumba zimbudzi mankhwala zida ntchito zochizira obalalitsidwa zimbudzi m'nyumba kapena zimbudzi zofanana m'nyumba, ndi akasinja osiyana ndi maudindo osiyana, mwachitsanzo: thanki sedimentation kulekana ntchito chisanadze mankhwala kuchotsa particles zazikulu zenizeni mphamvu yokoka ndi zolimba inaimitsidwa, ndi kusintha biochemistry wa zinyalala; tank pre-sefera ili ndi zodzaza, ndipo pansi pa zochita za anaerobic biofilm pa fillers, organics sungunuka amachotsedwa; thanki ya aeration imayikidwa ndi aeration, kuthamanga kwambiri kusefera, Tanki ya aeration imaphatikiza mpweya, kuthamanga kwambiri kusefera, kusungidwa kwa zolimba zoyimitsidwa ndi kubweza nthawi zonse; thanki yothira madzi osefukira ili ndi chipangizo chophera tizilombo toyambitsa matenda m'madzi.
Ntchito ya thanki yoyeretsera ndikuyeretsa zimbudzi zapakhomo, zomwe ndi mtundu wa malo ochitirapo zimbudzi pogwiritsa ntchito ukadaulo wakuthupi ndi wachilengedwe kuti uyeretse bwino zimbudzi zapakhomo, ndikuchitapo kanthu mwamphamvu kwa zimbudzi. The johkasou makamaka amatsuka zimbudzi zonse zapakhomo monga khitchini, kusamba, zovala ndi zimbudzi zofananira kuphatikiza zimbudzi za ndowe. Kapangidwe ka johkasou ndi yosiyana, ntchito ndi yosiyana, kawirikawiri kulankhula, johkasou zikuphatikizapo pretreatment, mankhwala amuzolengedwa mankhwala, sedimentation, kusefera ndi disinfection masitepe, pambuyo johkasou mankhwala madzi akhoza olumikizidwa kwa payipi maukonde kapena mwachindunji anamasulidwa ku mtsinje kapena minda.
Kodi ntchito za johkasou ndi septic tank ndi chiyani? Choyamba, johkasou ndi chipangizo chosonkhanitsira ndi kuyeretsa zimbudzi, zomwe zimagwiritsidwa ntchito posonkhanitsa zimbudzi zapakhomo kuchokera kuchimbudzi, khitchini, shawa, etc. Septic tank imangogwira ntchito yotolera zimbudzi kuchokera kuchimbudzi. Kachiwiri, johkasou makamaka amadalira luso thupi ndi kwachilengedwenso kuyeretsa zimbudzi mogwira ntchito zipangizo aeration kuonjezera kuchuluka kwa kusungunuka mpweya, imathandizira mapangidwe biofilm, potero utithandize zotsatira za zimbudzi kuyeretsa, septic thanki ndi ntchito sedimentation ndi anaerobic nayonso mphamvu kuthana ndi ndowe zinyalala.
Kuphatikiza apo, zimbudzi zakumidzi zakumidzi zomwe zimathiridwa ndi thanki yoyeretsera zimatha kufikira mulingo wa Class B mu Pollutant Discharge Standard for Urban Sewage Treatment Plants (GB18918-2002), ndipo akasinja ena oyeretsera amatha kufikira mulingo wa A Class A, ndipo mtundu wamadzi am'madzi amadzimadzi nthawi zambiri amakhala mu Class B muyezo mu Pollutant Sewage Treatment Plant Discharge Plant. (GB18918-2002). -2002) mu kalasi B muyezo kapena pansipa. Chofunika kwambiri, mtengo wake ndi wosiyana, mtengo wa thanki yoyeretsera uyenera kukhala yuan 3,000, kapena ma yuan zikwi zingapo, ndipo mtengo wa tank septic nthawi zambiri umachokera ku 500-2,000 yuan.
Choncho malinga ndi zosowa zosiyanasiyana za powonekera ndi luso lachuma kulipira, posankha zipangizo, mukhoza kusankha malinga ndi zosowa zawo reagent.
