Characteristics of activated carbon in Dongguan water treatment process

          There are many kinds of water treatment equipment processes in Dongguan, and biological activated carbon is one of them. Water treatment equipment to introduce to you: biological activated carbon, which refers to a water treatment process combined by ozonation, activated carbon adsorption, etc., let us understand the characteristics of the biological activated carbon method in Dongguan water treatment common sense.

          Complete biological nitrification to convert NH4+-N to NO-4; biological oxidation of dissolved organic matter can remove mg/l concentration of dissolved organic carbon (DOC) and trihalomethane formation potential (THMFP), and ng/l to The purpose of adding a small amount of oxidant (commonly used O3) to the water of μg/l level of organic matter is that the water treatment equipment converts the dissolved and colloidal organic matter into more easily biodegradable organic matter, and oxidizes some higher molecular weight humus to The low molecular weight and easily biodegradable substances become the nourishment source for the microorganisms in the charcoal bed.

          In the activated carbon bed, organic matter is adsorbed on the surface and small pores of the carbon particles, and microorganisms grow in the large pores on the surface of the carbon particles, and some organic matter is degraded through the action of cell enzymes. Therefore, the removal of organic matter lies in the dual of adsorption and biodegradation. effect.
