Malangizo pa mankhwala a zimbudzi - Masitepe khumi kuchimbudzi

1. Zowoneka bwino komanso zowoneka bwino

Zojambula zowoneka bwino komanso zowoneka bwino ndizomwe zimachitika m'malo opangiratu. Ntchito yawo ndikuchotsa ndi kutsekereza zinyalala ndi m'mimba mwake kuposa 5mm m'chimbudzi kuti zitsimikizire kuti njira yonyamulira zimbudzi zikuyenda bwino.

2. Chipinda cha grit cha Aerated

Ntchito yayikulu ndikuchotsa mchenga ndi mafuta ena m'zimbudzi, kuteteza zida zotsatsira madzi, kupewa kutsekeka kwa mipope ndi kuwonongeka kwa zida, ndikuchepetsa mchenga mumatope.

3. Thanki yoyamba ya sedimentation

Zolimba zoyimitsidwa m'chimbudzi zomwe zimakhala zosavuta kukhazikika zimatenthedwa ndikutulutsidwa m'malo opangira matope mu mawonekedwe a sludge kuti achepetse katundu woipitsa m'madzi.

4. Dziwe lachilengedwe

Tizilombo tating'onoting'ono mu sludge yomwe imakula kwambiri mu dziwe lachilengedwe imagwiritsidwa ntchito kusokoneza zowononga organic m'madzi, kuchotsa nayitrogeni ndi phosphorous, kuti akwaniritse cholinga choyeretsa madzi.

5. thanki yachiwiri ya sedimentation

Madzi osakanikirana pambuyo pa mankhwala am'chilengedwe amawalekanitsa kukhala olimba ndi madzi kuti atsimikizire mtundu wa madzi amadzimadzi.

6. Tanki ya sedimentation yapamwamba kwambiri

Kupyolera mu kusakaniza, flocculation ndi sedimentation, phosphorous yonse ndi zolimba zoyimitsidwa m'madzi zimachotsedwanso.

7. Chipinda chothira madzi a sludge

Mogwira kuchepetsa madzi zili sludge ndi kuchepetsa kwambiri kuchuluka kwa matope.

8. Sefa ya bedi lakuya

Kapangidwe kamankhwala komwe kumaphatikiza kusefera ndi ntchito za biological denitrification. Ikhoza kuchotsa nthawi imodzi zizindikiro zitatu za khalidwe la madzi za TN, SS ndi TP, ndipo ntchito yake ndi yodalirika, yomwe imapanga chisoni cha ntchito imodzi yaukadaulo ya akasinja ena osefera.

9. Ozoni kukhudzana thanki

Ntchito yayikulu yakuwonjezera kwa ozoni ndikuchepetsa zovuta za COD ndi chromaticity m'madzi kuti zikwaniritse zofunikira zamtundu wamadzi otayira.

10. Kupha tizilombo toyambitsa matenda

Onetsetsani kuti gulu lotayirira la coliform ndi mfundo zina zokhazikika zikukwaniritsidwa.

Madzi oyeretsedwa omwe amakwaniritsa "Miyezo ya Pollutant Discharge for Urban Sewage Treatment Plants" (DB12599-2015) akhoza kutayidwa mumtsinje!
