WATER PURIFYING APPARATUS

摘要

PURPOSE:To always supply clean water by parallelly arranging a water nitration module and a denitrification module both of which are packed with mineral substance to a forcible circulation flow path and arranging an oxygen supply means on the upstream side of the nitration module. CONSTITUTION:The sewage accumulated at the center of the bottom part of a water tank 2 passes through a water flow path (forward path) 3a from an inflow port 4 to enter a nitration module 7 and a denitrification module 10 both of which are packed with mineral substance 6 by a pump 5 and ammonia of the sewage entering the nitration module 7 is subjected to oxidative decomposition by the aerobic bacteria group bonded to the surface of the mineral substance 6 to become nitrate. Air is sucked in the nitration module 7 by the jet stream apparatus 8 arranged to the inlet of the nitration module 7 through a flow pipe 9 to generate oxygen-containing air bubbles and ammonia is perfectly oxidized by the aerobic bacteria group in the presence of air bubbles to become nitrate. This nitrate enters the denitrification module 10 to be perfectly decomposed into nitrogen and water.
