Ungayifumana njani ifilimu yeplastiki

Ukuphinda usebenzise kwakhona kunye nokuhlamba kweIfilimu / ifilimu yezolimo, Ingxowa ye-PPWE BIT / Ingxowa yeTon / Ibhegi ye-Bhanki iphawuleka ngokususwa ngempumelelo kwefilimu yeplastiki equkethe i-sediment.

Ngokuphuhliswa kweTekhnoloji yezoLimo kunye nokuphuculwa kwemigangatho yabantu, ifilimu yezolimo kunye nefilimu yezolimo isetyenziswe ngokubanzi kwitekhnoloji yezolimo, kuzisa izibonelelo ezinkulu kuphuhliso olukhulu kwezolimo kunye nokuphuculwa kwezinto ezahlukeneyo. Nangona kunjalo, ukusetyenziswa okukhulu kwefilimu yezolimo kuzisa neengxaki ezinkulu ukuzola umhlaba kunye nokurisayikilisha kwakhona. Ukongeza, ngenxa yeempawu zesicelo zefilimu yezolimo, kukho i-sediment eninzi; Ikwazisa neengxaki ezinkulu kwinkqubo yokuphinda isebenze. Ngenxa yale meko kunye neempawu zefilimu yezolimo. Siphuhlise ifilimu yeli filimu yezolimo, iphinde isebenze ngokutsha kunye nokusombulula imveliso yokusombulula iingxaki kunye nokusetyenziswa kwamanzi kwifilimu yezolimo iphinde isebenze kwakhona. Kwangelo xesha, isombulula ubunzima bezobugcisa bokuphelelwa ngamanzi emzimbeni, ukomisa, ukuqhutywa kunye nesivuno esikhulu. Okwangoku, ifakwe kakuhle eTshayina. Indlela ethile yenkqubo yile ilandelayo:

Ngenxa yomxholo ophezulu wodaka kunye nentlabathi (50-60%), zininzi ubunzima ekusetyenzisweni kwakhona, kwaye ingxaki yokunxiba zinkulu kakhulu, ngakumbi ukunxiba izixhobo ezityumkileyo, ezichaphazela kakhulu iziphumo. Ngokweempawu zayo, umatshini we-hydraulic bing kunye nomatshini wokucheba ekuqaleni kokuqala ukupakisha ifilimu yomhlaba ongcolileyo, emva koko usike ngokwe-150-200mm. Ibhloko nganye inqunyulwe amaxesha ama-5-7, kwaye emva koko idluliselwa ngumgangatho webhanti yokukhetha izinyithi ze-Drum, kwaye ingena kwiscreen se-Drum ukuze ikhutshelwe i-mesh, emva koko ingene kwi-mentirmer. Ngokujikeleza okuphezulu, i-mesh kwi-barrel ibonelelwe ukususa ubuncwane obuncinci kunye nodaka kunye nesanti. Kwaye izinyithi ezincinci zikhutshiwe, emva koko zingene kumngxunya otyumkileyo. Ngeli xesha, izinto ezinomxholo oqukethe malunga ne-10% ye-sediment, enciphisa kakhulu ukunxila komtyholwa kunye nokusika. Izinto ezitywiniweyo zicocwa ngesantya esiphezulu somoya kwaye sanqulwa sisifo sentlabathi, kwaye emva koko sibethelayo kunye nokuhlamba umakhali. Izinto ezibonakalayo zisasaza emanzini, kwaye isanti isusiwe ngokubekwa kukubetha kweeshafu kabini. Yahlulwe kwi-sediment, kwaye ingena kwi-racing ephantsi yokuhlamba ephantsi ukuze icoceke, kwaye ingena kwitanki yeqonga elilandelayo lokucoca kunye nokwahlukana. Iplastiki yokutyisa iplastiki ingena kwi-squeezer. Isixhobo esikhutshiweyo sikwimeko yeplastiki enesiphatho esenziwe ngomxholo wamanzi malunga ne-7-8%. Ithunyelwe kwigumbi lokugcina ngomoya lokuxhonywa kwamanzi ngokwendalo, emva koko ikhutshiwe. Ukutyiwa ecaleni kokondla okanye ukufihlakala kwamanqanaba amabini kunye negrafu yokukhala kwamanzi ayamkelwa.
