Iyo "Invisible Gamba" muSewage Treatment - Biological Filler

Wakambozvibvunza here kuti zvigadziriso zvematsvina zvinoshandura sei tsvina ine tsvina kuita mvura yakachena? Pamusoro pezvipo zvema microorganisms, pane zvakare zvinhu zvinopa chinyararire - biological filler. Zvakafanana ne "imba yezvakatipoteredza" mumvura, ichipa nzvimbo yekugara kune tupukanana uye kaviri kugona kwekunatswa kwetsvina. Nhasi, ngatitarisei iyi "gamba risingaoneki"!

I. Chii chinonzi biological filler?

Tsanangudzo:Biofiller ndiyo yakakosha inotakura zvinhu mubiofilm wastewater treatment process, kazhinji ine porous, yepamusoro-soro-nzvimbo yakasimba zvinhu. Inogona adsorb microorganisms kuti igadzire biofilms uye kubvisa zvinosvibisa kuburikidza ne biodegradation uye yemuviri adsorption.
Core mabasa:
Ipa nzvimbo yekuti ma microorganisms abatanidze uye awedzere biomass pavhoriyamu yeyuniti.
Kurebesa nguva yekugara kwema microorganisms uye kunatsiridza kubviswa kwekuita kwezvakaoma zvinosvibisa (zvakadai seammonia nitrogen uye organic matter).

II. Hunhu hwebiological fillers

1. Hydraulic performance optimization design
Iyo fluid mechanics zvimiro zvebiological fillers zvinonyanya kuratidzwa mumativi mana: chaiyo nzvimbo, pore chimiro, geometric morphology uye kurongedza density. Yakakwirira yakananga nzvimbo ndiyo mamiriro ekutanga ekuchengetedza yakakwira biomass kusungwa mu reactor, uye iyo biomass level inotaridza zvakananga kusvibisa kushatisa kugona kweiyo system. Nekudaro, kuwedzera kweiyo nzvimbo yakasarudzika kuchawedzera panguva imwe chete kupikisa kwemvura, zvichikonzera kuwedzera kwekushandiswa kwesimba reaeration.

Saizi yeporosity inokanganisa zvakananga vhoriyamu kushandiswa kweiyo reactor. Iyo yakakwirira porosity inogona kuwedzera iyo chaiyo yekugara nguva yetsvina, kuderedza kuyerera kwemvura, kuderedza njodzi yekuvharika uye kupfupi-kuyerera, uye kuderedza huwandu hwebiological filler uye mutengo wezvivakwa.

2. Kugadzikana kwemakemikari zvinodiwa
Iyo biofiller inofanira kunge isingadziviriri uye inokwanisa kutsungirira kukukurwa kwezvikamu zvemvura yakasviba uye microbial metabolites. Iyo pachayo inofanirwa kuve inert kudzivirira kunyungudika kwezvinhu zvinokuvadza zvinokonzeresa kusvibiswa kwechipiri, uye haifanirwe kuve nemakemikari anodzivirira kuita kwehutachiona. Iyo yemuviri nhanho inofanirwa kusangana nemichina yesimba zvinodiwa uku uchichengetedza huremu zvivakwa kuti uderedze system mutoro.

3. Nzira dzinosimudzira biofilm attachment
Kubudirira kwekuumbwa kwebiofilm kunoenderana neiyo physicochemical zvimiro zveiyo biofiller:

Zvinhu zvenyama:Surface roughness uye microporous chimiro ndizvo zvakakosha zvinhu. Nzvimbo dzakakasharara dzinogona kumhanyisa maitiro ekugadzira biofilm, nepo zvimiro zvemicroporous zvinosimudzira kuchengetwa kwehutachiona kuburikidza necapillary chiito.

Chemical properties:Surface kuchaja maitiro uye hydrophilic uye hydrophobic zvivakwa zvinoita basa rinotungamira. Kumusoro kwebhakitiriya kunowanzo kubhadhariswa zvisina kunaka, uye iyo yakanaka kugona pamusoro peiyo biofiller inogona kusimudzira sero kubatanidza kuburikidza ne electrostatic adsorption. Hydrophilic surfaces inogona kupfupisa zvakanyanya biofilm yekugadzira kutenderera.

4. Material mechanical properties
Chiyero chinoda kurohwa pakati pekureruka uye simba rakakwirira. Iyo yakanaka biofiller inofanirwa kuve neyakakwana yekumanikidza simba kuti irambe kuyerera kwemvura, uku ichichengetedza yakaderera density kuderedza mashandisiro emagetsi system.

5. Mafungiro ehupfumi
Mutengo webiofillers unowanzo verengera makumi matatu% -40% yekudyara kwese kweiyo biofilm maitiro, saka zvakakosha kusarudza zvinhu zvinodhura. Raw zvinhu zvine huwandu hwakasiyana siyana uye nyore kugadzirisa zvinofanirwa kufarirwa kuti uwane mutengo optimization uchive nechokwadi chekuita.

III. Iyo "Best Partner" Tekinoroji yeBiofillers

1. MBBR (Moving Bed Biofilm Reactor)
Features:Iyo biological filler inoyerera yakasununguka mudziva, uye hapana backwashing inodiwa.
InoshandaHigh-concentration sewage, kukwidziridzwa kwezvigadzirwa zvekare zvekuchenesa tsvina.

2. Biological kusangana oxidation dziva
Features:Biological fillers inogadziriswa mudziva uye inoda kucheneswa nguva dzose.
Inoshandatsvina yemumba, yakaderera-concentration industrial wastewater.

IV. Pfupiso: Sarudza iyo chaiyo biological filler kuti kurapa kwetsvina kushande

Biological filler ndiro "ecological cornerstone" yekuchenesa tsvina. Kusarudza chinhu chakakodzera uye maitiro anogona kuvandudza zvakanyanya maitiro ekurapa. Mune ramangwana, nekuvandudzwa kwezvinodiwa zvekuchengetedza kwezvakatipoteredza, zvinyowani zvinyowani senge graphene uye zeolite zvichave hotspot yekutsvagisa.

Iko kukosha kwehunyanzvi hwemabiological fillers haangoratidziri mukucheneswa kwemvura pachayo, asi zvakare kuburikidza nekubatanidza kwezvinhu zvitsva uye maitiro, inosimudzira kurapwa kwetsvina yakananga yakaderera-kabhoni uye kusimudzira-kwakavakirwa zviwanikwa, uye inova yakakosha tsigiro yehunyanzvi mune yemazuva ano yekutonga nharaunda yemvura.
