Kodi malo oipitsidwawo ataya mtengo wake wogwiritsidwa ntchito mpaka kalekale? Kodi pali njira yosinthira dothi lotayirira kukhala dothi labwino pamtengo wotsika?

Njira yothetsera nthaka ya Yichen imapangitsa kuti zosatheka.
Dothi la Yichen lokhazikika la nthaka limatha kugwira ntchito mamita 10 pansi pa nthaka, jekeseni wothandizira kukonzanso m'nthaka yowonongeka, ndikusakaniza mofanana chothandizira ndi nthaka yowonongeka kupyolera mu kusakaniza kwathunthu kwa chosakaniza mphamvu. Bwezerani thanzi ndi nyonga za nthaka.

Posintha zipangizo ndi chiŵerengero cha kuwonjezera zipangizo zoyenera zokonzetsera malinga ndi kuipitsidwa kwa nthaka, mphamvu zowononga nthaka zikhoza kusinthidwa, ndipo nthaka yokonzedwanso ingagwiritsidwe ntchito kulima mbewu. Zomwe zimachitika kawirikawiri zokonzanso zikuphatikizapo: nthaka acid-base neutralization, nthaka heavy metal kuipitsa kukonzanso, etc.

Kukonzanso nthaka yoipitsidwa ndi acid-base neutralization

Zomwe zili muzitsulo zolemera m'nthaka zimaposa muyezo ndipo ndi zamchere. Acid ndi alkali neutralization imachitika kudzera mu dongosolo lathu lokhazikika la nthaka.

Kukonzanso ndi kukonza nthaka yoipitsidwa ndi zitsulo zolemera
Kukhazikika ndi kukonzanso zitsulo zolemera m'nthaka, chithandizo chaumisiri cha nthaka yoipitsidwa ndi kubwezeretsanso zomera, kuti muchepetse chiopsezo cha zitsulo zolemera mu nthaka yoipitsidwa ku chilengedwe ndi thanzi la anthu.

Ntchito yokonzanso malo amatope ku Mazhuang Village, Xinji City
Pali malo otaya zinyalala mozungulira mudzi wa Mazhuang. Chifukwa cha milu ya zinyalala chaka chonse, nthaka pamalopo ndi yoipitsidwa kwambiri, yomwe sikuti imangotulutsa fungo loipa, ndikuyika thanzi la anthu akumudzi pachiswe. Komanso, malo osagwira ntchito omwe akhalapo kwa nthawi yayitali sangagwiritsidwe ntchito moyenera, ndipo palibe phindu lachuma lomwe lingapangidwe. Pofuna kuthetsa vuto la kuipitsidwa kwa nthaka, Yichen Environment inasankha othandizira oyenerera ndikugwiritsa ntchito nthaka yofewa ya in-situ solidification remediation system kuti athetse nthaka yowonongeka. Pambuyo pokonzanso, nthaka inafika pa mlingo wobzala, ndipo anthu a m’mudzimo anabzalapo tirigu. Njira yokonzanso imagwiritsa ntchito zida za dongosolo lokhazikika la nthaka, zosakaniza za 5m ndi 4m, zopangira 2m ndi 3m zowonjezera zowonjezera zowonjezera, kuya kwake kwakukulu kumafika mamita 7, ndipo cube yonse yomanga imafika 300,000 cubic metres.

Ntchito yokonzanso nthaka ya Wuhan Chemical plant idaipitsidwa
Mu Marichi 2015, Wuhan, m'chigawo cha Hubei, ntchito yokonzanso nthaka yoipitsidwa ya chomera chamankhwala, atasankha chowongolera choyenera cha dothi loipitsidwa, nthakayo idakonzedwanso, kulimba, kusanjidwa, ndikukonzanso wosanjikiza ndi wosanjikiza mpaka kuya pafupifupi. 1 mita. Pangani malo okhalamo. Ma seti atatu a dongosolo lokhazikitsira nthaka adagwiritsidwa ntchito pantchitoyi, ndi ntchito yatsiku ndi tsiku ya 1,200 cubic metres.
