Hurukuro pamakakatanwa ekupiswa kwemarara emanisipala

Mumakore maviri apfuura, kwave kune makakatanwa akawanda eEurope pamusoro pekupiswa kwemarara. Kune rimwe divi, dambudziko remagetsi rakonzera kuti marara akawanda apiswe kuderedza kushandiswa kwemafuta uye kuwanazve simba. Kunyangwe huwandu hwesimba rakadzoserwa hudiki, zvinonzwisiswa kuti inosvika 2.5% yesimba reEurope rinobva kune zvinopisa. Nekune rimwe divi, nzvimbo dzekurasira marara hadzichakwanise kusangana nezvino kugadzirwa kwemarara. Kuti uderedze huwandu hwemarara, kupisa ndiyo yakanyanya nyore uye inoshanda sarudzo.

Kubva muna Zvita 2022, kune makumi mashanu neshanu marara-kune-simba zvidyarwa zviri kushanda muUK, uye gumi nemasere ari kuvakwa kana kutumwa. Kune angangoita mazana mashanu ezvivakwa zvekupisa muEurope, uye huwandu hwemarara hwakapiswa muna 2022 hunosvika zviuru zvishanu nemazana mapfumbamwe ematani, kuwedzera kwakasimba mumakore apfuura. Zvisinei, sezvo zvimwe zvinopisira marara zviri pedyo nenzvimbo dzinogara vanhu nemafuro, vanhu vakawanda vari kunetseka pamusoro pezvakakanganiswa nharaunda neutsi hwazvinobudisa.

Muna Kubvumbi 2024, Dhipatimendi Rezvakatipoteredza reEngland rakamisa kupihwa kwemarezinesi ezvakatipoteredza emidziyo mitsva yekupisa marara. Kurambidzwa kwekanguva kunotora kusvika May 24. Mutauriri weDefra akati panguva yekurambidzwa kwenguva pfupi, kufunga kuchapiwa kuvandudza kushandiswazve, kuderedza kusvibiswa kwemarara kuti kubudirire chinangwa chekutsvaga zero, uye kana zvimwe zvivako zvekupisa marara zvichidiwa. Zvisinei, migumisiro yebasa nemimwe mirairo hazvina kupiwa pashure pokunge kurambidzwa kwenguva pfupi kwapera.

Midziyo yekupisa inogona kupatsanurwa zvakare zvichienderana nerudzi rwemarara anofanira kugadzirwa. Vanogona kukamurwa kuva:

①Mafuro ekupwanya epamusoro-soro eanaerobic pyrolysis uye kudzoreredzwa kwemafuta emafuta epurasitiki imwe chete kana matayi erabha.

②Madhiri echinyakare aerobic incinerators emarara akawanda anopisa akavhenganiswa (mafuta anodiwa).

③High-temperature pyrolysis gasification incinerators inoshandisa marara asara sehuni pasina kudiwa kwehuturu yekuwedzera mushure mekubvisa marara anogona kudzokororwa, asingabatike, uye anoparara (mafuta anongodiwa chete paunotanga choto).

Kudzokororwa uye kushandiswazve kwemarara emumaguta ndiwo maitiro akajairika ekurasa marara. Tsvina yakaoma yasara mushure mekurongedza ichiri kuda kuzoraswa kana kupiswa kuti iraswe kwekupedzisira. Kurongwa kwemarara munzvimbo dzakasiyana-siyana hakuna kuenzana, uye kunongova nemarara akawanda anofanira kuraswa. Zviwanikwa zvevhu zvishoma zvakaderedza kuwanda kwekurasira. Tichifunga nezvezvinhu zvese, kupisa marara ichiri sarudzo yakanaka yekurasa marara mumaguta.

Utsi hunogadzirwa mushure mekupiswa kwemarara hune dioxins, zvidimbu zvidiki zveguruva, uye NOx chinhu chakakosha chinokanganisa hutano hwevanhu uye nharaunda yakasikwa. Ndichowo chikonzero chikuru chinoita kuti vagari varambe kuvakwa kwenzvimbo dzekupisira marara. Iyo yakakwana uye yakakodzera flue gasi yekuchenesa sisitimu ndiyo yakanakisa mhinduro yekudzikisa iyi kukanganisa. Kuumbwa kwemarara akapiswa munzvimbo dzakasiyana kwakasiyana, uye kuwanda kwezvinosvibisa mugasi reflue rinogadzirwa kunosiyana zvakanyanya. Kuti uderedze re-synthesis ye dioxin, midziyo yekudzima inoshongedzerwa; electrostatic precipitators uye bhegi guruva vanounganidza vanogona kuderedza kuwanda kwediki guruva guruva mu flue gasi; iyo scrubber tower yakashongedzerwa nemishonga yekuwachisa kubvisa acidic uye alkaline magasi muflue gasi, nezvimwe.

HYHH ​​inogona kugadzirisa yakazara seti yetsvina yemumba yakakwira-tembiricha yepyrolysis uye gasification masisitimu kwauri zvichienderana nemamiriro chaiwo epurojekiti yenzvimbo, kuti uwane kuderedzwa kwemarara uye kusangana nemiyero yekuburitsa, inova nzira iripo yegirinhi uye ine hushamwari yekurasa marara. . Kugamuchirwa kuti usiye meseji yekubvunzana!
