Icala Lokusetshenziswa Kwesitshalo Sokuhlanza Indle eBeijing

Esinye isikhungo sokwelapha indle eBeijing singenye yezakhiwo ezakhiwe ukuxazulula izinkinga zokwelashwa kwendle edolobheni nasezindaweni ezizungezile. Saqedwa ngokusemthethweni futhi saqala ukusetshenziswa ngoJuni 2009. Njengamanje, indawo ephakathi yedolobha isebenzisa uhlelo lokukhipha amanzi oluhlanganisiwe ngaphandle kwezindawo zokuhlanza indle. Indle ayiphathwa futhi ikhishwe emfuleni ngepayipi elihlanganisiwe elikhona, okubangela ukungcola okukhulu esimweni samanzi esikhona. Njengoba ukwakhiwa kwedolobha kuqhubeka ngokushesha, inani labantu edolobheni likhula ngokushesha, futhi inani lendle liyakhula usuku nosuku. Ngaphezu kwalokho, ukuze kuvikelwe imithombo yamanzi yedolobha, njengengxenye ebalulekile yengqalasizinda yedolobha, kuyadingeka ukwakha isitshalo sokwelapha indle kuleli dolobha. Kuzokwakhiwa indawo entsha emanzi yokwenziwa ezungeze isitshalo sokwelapha indle, futhi amanzi ahlinziwe azosetshenziswa njengomthombo wendawo emanzi yokwenziwa noma akhishwe emfuleni othile. Isikali sephrojekthi singama-20000 m3/ngosuku esikhathini esizayo esiseduze kanye nama-30000 m3/ngosuku esikhathini eside.

Isakhiwo esiyinhloko sihlanganisa: igumbi lokupompa amanzi (kufaka phakathi igumbi le-grille), igumbi lokugaya isiphepho, igumbi lokuwasha isihlabathi, umsele wokuvuvukala kobuso, ithangi lokudaya, igumbi lokupompa amanzi, igumbi lomshini wokukhipha amanzi odakeni kanye nethangi lokugcina udaka, amashede okugcina udaka, iziteshi zokubulala amagciwane ze-UV, izikhungo zokususa iphunga kanye nezakhiwo, kanye namakamelo okulinganisa; ezinye izakhiwo nezakhiwo zifaka igumbi lesiteshi esikhulu, isakhiwo esibanzi, ichibi lomlilo kanye negumbi lokupompa, igumbi lepompo yokushisa, i-warehouse, igumbi lokulungisa, kanye negumbi lokuxhumana. Isakhiwo esibanzi sihlonyiswe ngegumbi lokulawula eliphakathi nendawo kanye nelebhu, elingaqapha futhi lilawule idatha ehlukahlukene ngempumelelo. Ukuze abasebenzi abasendaweni bakwazi ukulungisa amapharamitha enqubo ngesikhathi esifanele. Isikhungo sethu sisebenzisa indlela ye-oxidation ditch esebenzayo yokwelapha indle ngokwesibili, sicabangela izidingo zokususwa kwe-phosphorus ne-nitrogen.

Uimikhiqizo yokucula:

I-Shanghai BOQU Instrument inikeza inhlanganisela yokuqapha okuzenzakalelayo kanye nokuqapha ngesandla kulo msebenzi, Ukuqapha okuzenzakalelayo kuxazulula izinkinga zenkampani zokuzisebenzela kanye nokugcinwa kwesitshalo sokuhlanza indle futhi kuqinisekisa ukuzinza nokuthembeka kwekhwalithi yamanzi ngesikhathi senqubo yokwelapha yenkampani. Ukuqapha ngesandla iBeijing Urban Drainage Monitoring Station ephathiswe ukuqapha kwenza ukuqapha. Ngomsebenzi ophelele wokuqapha nokulawula ikhwalithi yamanzi ukuqinisekisa ikhwalithi yamanzi ezinzile nethembekile.
