Ku saabsan Leachate Qashin-qubka

Ma garanaysaa?Marka laga soo tago qashinka u baahan in la kala saaro, waxa kale oo loo baahan yahay in la kala saaro wasakhda qashinka.

Marka loo eego sifada wasakhda qashin-qubka, waxa si fudud loo kala qaybin karaa: wasakhda wasakhda wasakhda qashin-qubka ee xarunta wareejinta, wasakhda wasakhda jikada, wasakhda wasakhda qashin-qubka, iyo gubista caleenta warshadda qashinka.

Maxay yihiin sifooyinka afartan nooc ee wasakhda qashinka qashinka?

Astaamaha dheecaanka saldhiga wareejinta:

1. Waxa jira ilo badan oo waaweyn oo ay ka helaan biyaha wasakhda ah: inta badan biyaha wasakhda ah ee guriga, daadinta biyaha wasakhda ah, iyo wasakhda qashinka qashinka.

2. Wakhtiga yar ee qashinku ku nool yahay goobta qashinka, waxa ka soo baxaya dheecaanku wuu yar yahay.

3.Isku-duubnaanta wasakhaha ee xarunta wareejinta way ka hoosaysaa tan wasakhowga kale, iyo fiirsashada COD waxay ku saabsan tahay 5000 ~ 30000mg/L.

Astaamaha ugu muhiimsan ee leachate qashin-qubka waa:

①Waxaa jira noocyo badan oo wasakh dabiici ah, tayada biyuhuna waa mid adag (waxaa ku jira daraasiin walxo organic ah)

②Isku-duubnaanta sare ee wasakhowga iyo isbeddello kala duwan (bilawga BOD iyo COD-ururinta ayaa ah kuwa ugu sarreeya, ilaa tobanaan kun oo milligram halkii litir, qiimaha pH waa ama wax yar ka hooseeya 7, B/C waxay u dhaxaysaa 0.5-0.6, iyo guryaha biochemical waa wanaagsan yihiin) , guud ahaan marka la hadlo, saamiga COD, BOD, BOD/COD wuxuu hoos u dhacaa "da'da" qashin-qubka, iyo alkalinityku wuu kordhaa

③Tayada iyo tirada biyuhu aad bay u kala duwan yihiin: tirada biyuhu aad bay u kala duwan yihiin xilliyada (xilliyada roobabku way ka weyn yihiin xilliga qalalan);Isku-dhafka iyo xoojinta wasakhowga ayaa sidoo kale isbeddelaya xilliyada;Isku-dhafka iyo fiirsashada wasakhowga ayaa isbedelaya wakhtiga qashinka.

Astaamaha ugu muhiimsan ee wasakhda qashin-qubka ee dhirta gubidda waa:

①Heerarka sare ee COD, BOD, iyo nitrogen ammonia (COD waxay gaari kartaa 40,000 ~ 80,000)

②Waqtiga halsano ayaa ka badan kan goobta wareejinta.

Tilmaamaha ugu muhiimsan ee wasakhda qashinka jikada:

①Caleenta adag ee sare ee la hakiyey: Caleemaha kala duwani waxay leeyihiin qaybo kala duwan oo ah adkaha la hakiyey ee gobolka la dajin karo iyo kolloidal, ilaa 60,000 ilaa 120,000 mg/L, oo ​​leh kala firdhis sare oo ay adagtahay in la kala saaro;

②Saliida sare: badiyaa saliida xoolaha iyo khudradda, ilaa 3000mg/L ka dib daawayn ka dib

③COD sare, sida caadiga ah way fududahay in biodegrade, ilaa 40,000 ilaa 150,000 mg/L;

④pH yar (badanaa qiyaastii 3);⑤milix badan.
