Kanalizatsiya tozalash inshootlarida koagulyantlardan foydalanish ta'siriga qanday omillar ta'sir qiladi?

Kanalizatsiya tozalash inshootlaridan foydalanish jarayonida kanalizatsiya tozalashning koagulyatsion ta'siriga ta'sir qiluvchi ba'zi omillar mavjud va ta'sir etuvchi omillar turli xil bo'lib, ular asosan turi, kontsentratsiyasi, koagulyant miqdori, koagulyatsion tozalash paytida aralashtirish holati, PH qiymati, harorat va uning o'zgarishi va hokazo. Quyidagi kichik seriyalar kanalizatsiya tozalashning koagulyatsion ta'siriga qaysi omillar ta'sir qilishini maxsus kiritadi.

1. The type and amount of coagulant, different humectants should be used for different wastewater. The amount of coagulant affects the coagulation effect to a great extent, and both excess and deficiency will lead to the dispersion and stability of the sol particles. Therefore, the optimal dosage should be determined through experiments. Generally speaking, the dosage of inorganic coagulants is relatively high, often reaching hundreds to thousands of mg/L, while organic polymer coagulants are mainly used for coagulation assistance. , the dosage is small, usually 1·10mg/L, and the maximum does not exceed 25mg/L.

2. Aralashtirish va reaktsiya vaqtining ta'siri, ma'lum bir koagulyant to'liq eriganidan so'ng, hosil bo'lgan kolloid suvdagi asl kolloid va to'xtatilgan modda bilan aloqa qilgandan keyin ko'plab mayda alum gullarini hosil qiladi. Bu jarayon aralash deb ham ataladi. Aralashtirish jarayoni kuchli turbulentlik hosil qilish uchun suv oqimini talab qiladi, shuning uchun agent va suv nisbatan tez vaqt ichida to'liq aralashtirilishi mumkin va aralashtirish vaqti odatda o'nlab soniyadan 2 minutgacha davom etadi. Aralashtirish odatda gidravlik yoki mexanik vositalar yordamida amalga oshiriladi.
