Domestic tsvina yekurasira marara papuratifomu nzvimbo yekurasira ivhu yekuvhara HDPE Geomembrane ，Zoning marara chivharo zvinoenderana neakakodzera dhizaini firimu HDPE Overlay firimu. Pamusana pemamiriro ezvinhu akaoma ekuvhara, nzvimbo yekuvhara inosvika makumi ezviuru zvemamita emamita, uye majoini emafirimu ekuvhara akareba, hazvidziviriki kuti mamwe mafirimu anovhara achave nekuputika. Vashandi vepaLandfill vanoshandisa nguva yavo yemahara kugadzirisa kuvuza kwemafirimu anovhara. "Firimu racho rakaradzikwa kwemaawa maviri nehafu mangwanani, uye mapepa mashanu akaiswa." Firimu rekuvhara "rinoreva high-density polyethylene geomembrane yakavharwa pamarara." Mushure mokunge marara akazara, kuifukidza nefirimu iyi zvakaenzana nekuisa a'coat'on marara, izvo zvinogona kuderedza kunhuwa. “
Kuisa nzira yekurasa marara inovhara firimu
Sub-unit landfill, marara paving uye compaction haina kuzorora. Nzvimbo yekurashira ivhu ine migumo yepasi yakaganhurwa maviri kuti igovane nzvimbo yese yedhamu kuita nzvimbo nhatu dzekurasira marara. Iyo sub-unit dhishi chirongwa chegore rose inogadzirwa uye iyo yekushanda unit inodzorwa zvinoenderana nezvinodiwa neiyo yakatarwa, iyo leachate drainage pombi pamigero yepasi yakatemwa inogurwa uye yakavharwa, mvura inonaya uye yekugezesa tsvina inoitwa kune hupamhi hwepamusoro, huwandu hweleachate inogadzirwa inodzikiswa, uye njodzi dzenharaunda nemitengo yekugadzira zvinodzikiswa.
Landfill inoshandisa yakakosha muchina, mabulldozer uye ma compactor paving uye compaction. Iyo compaction density yemarara inogara ichiyedzwa, kuumbwa kwemarara kunogara kuchiongororwa, uye yakaturika rolling uye layered paving inoitwa sezvinodiwa. Iyo imwechete-layer paving ukobvu inodzorwa pa 0.5 kusvika 1 mita, uye iyo unit ukobvu inodzorwa pa4 kusvika 6 metres.
3, Uifukidze mazuva ose kuti munhuwi usapararire, uye panguva imwe chete uderedze mvura inonaya kuti isapinda munoraswa marara, udzore kuberekana kweumhutu nenhunzi, uye kudzivirira kupararira kwehwema.
Nzvimbo iri pasi pekuvharidzirwa munzvimbo yekugadzira tsvina ichashandiswa masikati ega ega 1.0 HDPE Iyo membrane yakavharwa kwechinguva, uye nzvimbo dzose dziri kunze kwechiso chekushanda ndeye 1.0 mm Iyo yakafukidzwa nepamusoro-density polyethylene firimu, uye firimu rinovhara munzvimbo. iyo isati yashandiswa kwemazuva anopfuura 15 inobatanidzwa uye yakasungirirwa. Mvura yakachena pafirimu inobudiswa kuburikidza nemateru echisikigo kana mugero wemvura inonaya wakaiswa panzvimbo yacho, kuitira kuti kuderedza mvura inonaya ichipinda mumarara, uye kunyatsogadzirisa kubereka kweumhutu nenhunzi uye kupararira kwekunhuwa. Ichi chinongedzo chakakosha zvikuru, kunyanya pakutsauswa kwemvura inonaya netsvina. Munguva yechando, tichapedza kuchera uye kugadzirisa madhishi ekuvharisa mafashama, kusimbiswa kwemigwagwa kwenguva pfupi munzvimbo dzinoraswa marara, kuongorora nekugadzirisa mafirimu anovhara, kuvakwa kwenzvimbo dzakatemerwa pasi, uye kutamiswa uye kumiswa kwemapombi pamberi. Ita gadziriro dzakazara dzekusimbisa kuchengetedzwa kwekugadzira uye kuderedza njodzi kwezvakatipoteredza munguva yekunaya kwemvura. ”
Iyo yekubatanidza chikamu pakati pekurasa marara uye muteremu munzvimbo yedhamu yakaiswa pa50 CM Sand bhegi yekudzivirira layer, mutsetse unodzorwa pazasi 1: 3, uye murwi wekukwirira kwemurwi wakakamurwa kuita longitudinal kutsetseka uye kuchinjika materu modhi. Iyo nzvimbo yakazadzwa inogamuchirwa HDPE Membranes inovharirwa yepakati-temu.
4, Hapana kusiiwa mukuuraya utachiona hwesaiti. Masprinklers anoshandiswa kuwedzera zvakananga makemikari mumigwagwa iri panzvimbo, uye mhepo dzemhepo dzinoshandiswa kuita otomatiki kupfapfaidza mashandiro ekuuraya hutachiona uye deodorization. Panguva imwecheteyo, kuvhara kwezvikwata zvekushanda kunosimbiswa. Parizvino, kudzora mhedzisiro yeumhutu, nhunzi uye kunhuhwirira munzvimbo yakanaka.
Mambure ekudzivirira kubhururuka anoiswa kumativi ese enzvimbo yekurasira marara kuti avhare zvine hungwaru zvinhu zvinobhururuka.
