Udindo wa Johkasou pa Kusamalira Zinyalala Zakumidzi

Johkasou ndizipangizo zazing'ono zoyeretsera zinyalala zapakhomoamagwiritsidwa ntchito pochiza zinyalala zapakhomo zomwazika kapena zinyalala zofanana zapakhomo, ndipo matanki osiyanasiyana ali ndi ntchito zosiyanasiyana, mwachitsanzo: thanki yolekanitsa sedimentation imagwiritsidwa ntchito pochiza zinyalala zazikulu komanso zolimba zomwe zapachikidwa, komanso kukonza biochemistry ya zinyalala; thanki yoyambira kusefera ili ndi zodzaza, ndipo pansi pa ntchito ya biofilm ya anaerobic pa zodzaza, zinthu zachilengedwe zosungunuka zimachotsedwa; thanki yoyambira imayikidwa ndi mpweya, liwiro lalikulu losefera, Thanki yoyambira imaphatikiza mpweya, liwiro lalikulu losefera, kusunga zinthu zolimba zomwe zapachikidwa komanso kusamba m'mbuyo nthawi zonse; thanki yodzaza madzi ambiri ili ndi chipangizo choyeretsera zinyalala kuti ichotse zinyalala.

Ntchito ya thanki yoyeretsera ndi kuyeretsazimbudzi zapakhomo, yomwe ndi mtundu wa malo oyeretsera zinyalala pogwiritsa ntchito ukadaulo wachilengedwe komanso wachilengedwe kuti ayeretse bwino zinyalala zapakhomo, zomwe zimapangitsa kuti zinyalala zikhale zolimba. Johkasou imasamalira zinyalala zonse zapakhomo monga kukhitchini, kusamba, kuchapa zovala ndi zinyalala zina zofanana kuphatikiza zinyalala za ndowe. Kapangidwe kajohkasouNdi yosiyana, ntchito yake ndi yosiyana, nthawi zambiri, johkasou imaphatikizapo chithandizo chisanachitike, mankhwala a biochemical, sedimentation, kusefa ndi njira zophera tizilombo toyambitsa matenda, madzi okonzedwa ndi johkasou akatha kulumikizidwa ku netiweki ya mapaipi kapena kutulutsidwa mwachindunji ku mtsinje kapena minda.

Kodi ntchito za johkasou ndi thanki ya septic ndi ziti? Choyamba, johkasou ndi chipangizo chosonkhanitsira ndi kuyeretsa zinyalala, chomwe chimagwiritsidwa ntchito kusonkhanitsa zinyalala zapakhomo kuchokera kuchimbudzi, kukhitchini, shawa, ndi zina zotero. Thanki ya septic imangotenga zinyalala kuchokera kuchimbudzi. Kachiwiri, johkasou imadalira kwambiri ukadaulo wakuthupi ndi wachilengedwe kuti iyeretse bwino zinyalala, pogwiritsa ntchito zida zopumira mpweya kuti ziwonjezere kuchuluka kwa mpweya wosungunuka, kufulumizitsa mapangidwe a biofilm, motero kukulitsa mphamvu ya kuyeretsa zinyalala, thanki ya septic ndi kugwiritsa ntchito sedimentation ndi anaerobic fermentation kuti ithane ndi madzi otayira a ndowe.

Kuphatikiza apo, zimbudzi zakumidzi zomwe zimatsukidwa ndi thanki yoyeretsera zitha kufika pamlingo wa Class B mu Pollutant Discharge Standard yaMalo Otsukira Zinyalala ku Mizinda(GB18918-2002), ndipo matanki ena oyeretsera amatha kufikira muyezo wa Class A, ndipo mtundu wa zinyalala za thanki ya septic nthawi zambiri umakhala mu muyezo wa Class B mu Pollutant Discharge Standard for Urban Sewage Treatment Plants (GB18918-2002). -2002) mu muyezo wa class B kapena pansi pake. Chofunika kwambiri, mtengo wake ndi wosiyana, mtengo wa thanki yoyeretsera uyenera kukhala osachepera 3,000 yuan, kapena ngakhale ma yuan masauzande angapo, ndipo mtengo wa thanki ya septic nthawi zambiri umakhala pakati pa 500-2,000 yuan.

Chifukwa chake malinga ndi zosowa zosiyanasiyana za malo ndi kuthekera kwachuma kolipira, posankha zida, mutha kusankha malinga ndi zosowa zawo za reagent.
