15、r matter apart from the resin, at the same time, make the water go from the catchment equipment at the bottom, let the water line rise and the resin expand. When it expend to about 50% of the water level, lose the air outlet valve. At the same time, open the water discharge valve of UP-SPT and water

16、 discharge valve of DOWN-SPT, to make the medium and the gabby resin out of the tin with the water. Repeat this procedure several times, until the resin is clean again. Then use the 5% alkali and acid respectively to regeneration as normal, until the outlet water conductivity10s/cm. At last, the cat

17、ion resin and anion resin regeneration procedure ends.再生好的陰樹脂從陰樹脂再生罐用水和壓縮空氣輸送到陽樹脂再生罐，進(jìn)行陰、陽樹脂的混合，然后再向陽樹脂再生罐注滿水后，進(jìn)行大流量沖洗直到排水達(dá)到混床的出水指標(biāo)后停止沖洗，樹脂再生合格備用。Use water and compressed air to transport the regenerated anion resin from ART to CRT and mix them. After fulfill the water into the CRT, we should flush

18、them in large flux, until the outlet water meet the MB Outlet Water Quality Standardand then keep the eligible resin as spare used.So the CRT is not only for the cation resin regeneration, but also as a packet to deposit the eligible resin after regenerated.3調(diào)試應(yīng)具備的條件Precondition before commissioning
