Study on Biological Sand Filtration System and Conventional Water Treatment in Micro-Polluted Source Water
Compared biological sand filtration system with conventional water treatment, taking micro-polluted water river as source water. The results show that biological filtration system is excelled to conventional water treatment, the removal rate of CODMn, NH4+-N, chromaticity and turbidity is 34~56％, 78.7~92%, 53~68%, 90% by biological sand filtration system; however, the removal rate of CODMn, NH4+-N, chromaticity and turbidity is only 11~30%, 4.7~25%, 38~54%, 60~80% by the conventional water treatment and the remval effection is instability; therefore, biological filtration system is pertinency and feasibilty in the micro-polluted source water.
