Raws li peb txhua tus paub, kev kho dej phwj hauv nroog nyob deb nroog yuav tsum tau ua ke nrog qhov xwm txheej tiag tiag ntawm tib neeg nyob deb nroog kom coj mus rau hauv ib cheeb tsam, thiab tib lub sijhawm paub txog kev siv peev txheej thiab kev tswj hwm kev ua qias tuaj. Kev siv cov dej phwj tuaj nyob deb nroog tom qab kev kho mob me me tuaj yeem txo qis kev siv dej phwj tuaj, rov ua dua cov dej ua liaj ua teb thiab cov khoom siv nitrogen thiab phosphorus, thiab siv tag nrho cov peev txheej av nyob deb nroog thiab cov dej huv ib puag ncig. Vim tias qhov kev xav tau ceev nrooj los txhim kho qhov chaw nyob deb nroog, kev siv cov dej phwj tuaj nyob deb nroog yuav yog lub hom phiaj mus ntev rau kev txhim kho cov dej phwj tuaj.
Lub chaw ua haujlwm ceev ceev yuav tsum tau tshem tawm ntawm qhov kev xav
Tam sim no, Tuam Tshoj txoj kev kho dej phwj nyob deb nroog, feem ntau yog siv cov chaw sib xyaw + cov txheej txheem ecological, tab sis kev ua haujlwm ntawm cov chaw tsis zoo. Qee qhov chaw kho mob hauv nroog cov dej phwj tuaj 'miniaturisation', kev tsim kho, kev ua haujlwm thiab kev saib xyuas cov nqi siab, cov chaw nyob deb nroog nyuaj rau kev lees txais, tab sis kuj tsis quav ntsej txog kev siv cov dej phwj hauv tsev los tswj lub luag haujlwm ntawm cov av fertility. Vim muaj kev txwv kev lag luam nyob deb nroog thiab kev siv thev naus laus zis, ntau cov dej phwj tuaj kho cov dej num, kom ntau thaj chaw ntawm cov chaw kho mob, cov kav dej sib txuas tsis tuaj yeem tsim, tsis tuaj yeem them taus, tsis muaj cov kws tshaj lij thiab cov neeg ua haujlwm tswj xyuas. Hauv cov ntsiab lus tam sim no ntawm kev loj hlob sai, kev kho cov dej khib nyiab hauv nroog nyob deb nroog yuav tsum txo qis cov nqi sunk xws li kev tsim kho vaj tse thiab cov kav dej sib txuas, tshem tawm ntawm kev xav, thiab txhawb nqa tus nqi qis, yooj yim-rau-tus qauv ntawm kev kho mob me me thiab kev siv peev txheej.
Kev siv cov peev txheej tau hais meej hauv cov qauv tso tawm
Nyob rau hauv cov nqe lus ntawm cov qauv emission tau siv rau kev kho cov dej khib nyiab nyob deb nroog, nyob rau xyoo tas los no, kev kho nruab nrab thiab kev siv cov peev txheej tau maj mam hais meej hauv cov qauv emission. Raws li kev txheeb cais, feem ntau lub hauv paus rau kev siv cov qauv kev kho mob yog GB18918-2002, tab sis nyob rau hauv 2019, Ministry of Ecology thiab ib puag ncig tau tshaj tawm 'Cov Lus Qhia rau Kev Npaj Cov Dej Pleev Emission Control Specifications for Rural Domestic Wastewater Treatment. Cov Tsev Kawm Ntawv (rau kev sim ua tiav)' (Environmental Affairs Office Soil Letter 〔 2019 〕 No. 403), uas txhawb nqa qhov kev xaiv zoo tshaj plaws ntawm nitrogen thiab phosphorus resourcing thiab tail water technologies. Tom qab ntawd, cov qauv tso tawm tshiab tawm hauv cov xeev thiab nroog kuj tau so lawv lub hom phiaj. Kev kho nruab nrab ntawm cov dej khib nyiab nyob deb nroog tau hais txog thiab txhawb nqa los ntawm sab saum toj mus rau hauv qab, tso lub hauv paus rau kev siv cov peev txheej tom ntej.
Regionalised Sewage Resource Utilization Development Direction
Artificial wetland yog tam sim no siv ntau tshaj plaws hauv kev siv dej phwj hauv nroog hauv nroog. Daim ntawv thov ntawm kev siv cov dej phwj tuaj nyob deb nroog hauv Suav teb tseem nyob rau theem ntawm cov av ntub dej, stabilization pas dej thiab ecological av purification. Raws li kev ua liaj ua teb muaj kuab paug nrog rau cov dej phwj hauv nroog nyob deb nroog tau dhau los ua qhov tseem ceeb ntawm cov pa phem nyob deb nroog hauv Suav teb, kev tswj hwm tag nrho cov dej phwj tuaj, qhov chaw txo qis-pre-blocking-resourcefulness-ecological restoration yuav yog txoj kev loj hlob ntawm kev ua liaj ua teb saum npoo av tswj cov pa phem. Ib yam li ntawd, cov dej phwj tuaj nyob deb nroog yuav tsum siv cov peev txheej hauv cheeb tsam. Ntxiv dag zog rau kev pabcuam kev ua haujlwm ntawm cov ecosystems nyob deb nroog los ntawm kev hloov pauv hloov pauv, suav nrog cov chaw kho dej khib nyiab nyob deb nroog, uas tsuas yog tsom mus rau kev txo cov peev txheej, nrog rau kev ua liaj ua teb rov ua dua tshiab, qhia txog cov kev kho mob hauv cheeb tsam sib haum nrog kev ua liaj ua teb, thiab muab kev ua si tag nrho rau lub luag haujlwm ntawm kev tswj hwm, agro -ecosystems lawv tus kheej ua hauj lwm nyob rau hauv ib txoj kev uas txo cov pa phem tiam thiab tso tawm.
Cov lus saum toj no yog tag nrho cov ntsiab lus ntawm qhov teeb meem no, cov ntsiab lus ntxiv thov ua tib zoo saib rau qhov teeb meem tom ntej ntawm Li Ding ib puag ncig tiv thaiv los qhia. Li Ding tau cog lus rau kev tshawb fawb thiab kev tsim kho, kev tsim kho thiab kev ua haujlwm ntawm cov khoom siv dej phwj nyob deb nroog tau kaum xyoo. Los ntawm kev nruam kev thev naus laus zis tshiab, peb siv zog ua kom muaj txiaj ntsig zoo rau kev txhim kho tib neeg ib puag ncig ntawm ib sab. Li Ding ib puag ncig kev tiv thaiv tsev neeg hom dej phwj kho khoom siv scavenger tuaj yeem siv tau zoo heev rau feem ntau ntawm cov chaw nyob deb nroog.
