Nrog rau kev nce ntxiv ntawm cov peev txheej dej thoob ntiaj teb, kev siv tshuab kho dej khib nyiab tau txais kev saib xyuas dav dav.Cov khoom siv kho dej khib nyiab PPH sib xyaw ua ke, ua ib qho kev daws teeb meem dej khib nyiab zoo thiab zoo rau ib puag ncig, tau siv dav hauv tsev thiab txawv teb chaws.
Kev tsim kho thiab kev hloov pauv ntawm PPH cov khoom siv kho dej khib nyiab sib xyaw ua ke tuaj yeem taug qab rov qab mus rau xyoo 1970. Lub sijhawm ntawd, nrog rau kev txhim kho sai ntawm kev lag luam thiab kev loj hlob hauv nroog, kev kho dej khib nyiab tau dhau los ua teeb meem loj heev rau ib puag ncig. Ib txwm muajkev kho dej phwj tuajCov txheej txheem feem ntau siv cov txheej txheem lub cev thiab tshuaj lom neeg, nrog rau kev kho mob qis thiab kev siv hluav taws xob ntau. Txhawm rau daws qhov teeb meem no, cov kws tshawb fawb tau pib tshawb nrhiav kev ua haujlwm zoo dua thiab zoo rau ib puag ncigkev kho dej khib nyiabcov thev naus laus zis.
Hauv qhov xwm txheej no, cov khoom siv kho dej khib nyiab PPH tau tsim los. Nws siv txoj kev kho mob biological, kev sib xyaw ua ke ntawm kev kho aerobic, kev kho anaerobic thiab lwm txoj kev kho mob, nrog kev kho mob zoo, cov nqi khiav lag luam qis, thiab lwm yam. Kev tshwm sim ntawm PPH cov khoom siv kho dej khib nyiab sib xyaw ua ke txhawb nqa kev nce qib ntawm cov thev naus laus zis kho dej khib nyiab, thiab dhau los ua cov tshuaj kho dej khib nyiab zoo thiab zoo rau ib puag ncig.
Nrog rau kev nce qib tas mus li ntawm thev naus laus zis thiab kev tiv thaiv ib puag ncig, cov khoom siv kho dej khib nyiab PPH kuj tseem niaj hnub tsim kho thiab hloov pauv. Cov khoom siv thaum ntxov yog rau kev kho dej khib nyiab yooj yim los ntawm cov tsev neeg, cov zej zog me me thiab cov chaw lag luam. Nrog rau kev nthuav dav ntawm lub nroog thiab kev txhim kho sai ntawm kev lag luam, qhov kev thov rau kev kho dej khib nyiab nce ntxiv, thiab qhov loj me thiab kev ua tau zoo ntawm cov khoom siv kho dej khib nyiab PPH kuj tseem niaj hnub hloov kho.
Cov txheej txheem kho kab mob ntawm PPH cov khoom siv kho dej khib nyiab sib xyaw ua ke muaj txiaj ntsig zoo, uas tuaj yeem tshem tawm cov organic teeb meem, nitrogen, phosphorus thiab lwm yam kuab paug hauv cov dej phwj kom ua tiav cov ntsuas dej zoo. Cov khoom siv muaj cov qauv me me thiab qhov chaw me me, uas tsim nyog rau kev siv hauv cov chaw uas muaj qhov chaw tsawg. PPH sib xyaw ua kecov khoom siv kho dej khib nyiabFeem ntau nws muaj lub tshuab tswj tsis siv neeg, uas ua rau koj tuaj yeem saib xyuas thiab kho qhov chaw deb thiab txo tus nqi ntawm kev ua haujlwm tes. Cov khoom siv no siv cov thev naus laus zis ua kom muaj cua nkag tau zoo los txo kev siv hluav taws xob; tib lub sijhawm, nws cov qauv tsim zoo pab txo cov nqi khiav lag luam. Cov txheej txheem kho kab mob yog tus phooj ywg rau ib puag ncig thiab txo qhov cuam tshuam tsis zoo rau lub ecosystem.
Yuav kom xaiv tau cov khoom siv kho dej khib nyiab zoo PPH, kev tsim khoom siv thev naus laus zis thiab kev ua haujlwm hauv qhov project yog qhov tseem ceeb, feem ntau, koj yuav tsum xaiv cov khoom uas tuaj yeem txuas ntxiv mus rau qhov kev xeem ntawm kev ua lag luam, ntawm no kom pom zoo cov khoom siv PPH tsim los ntawm Liding Environmental Protection Company, uas tuaj yeem hloov kho raws li kev thov ntawm kev ua lag luam rau hom khoom tsim nyog.
