Process Study Of The Adsorption - Mild Oxidation Technology For Treating Polluted Water Body

This text studies technology conditions and mechanism of adsorb - oxide technology dealing with the light polluted water.By way of the captive test we define the feasibility of using adsorb - oxide technology dealing with light polluted water. The result of the captive test indicates : Adsorb- oxide technology can degrade pollutant of the light polluted water rapidly in 2.0 hours, and remain higher effect in degrading CODcr , NHs-N and TP respectively by 79.3% , 88.4% and 80%.The test on field is carried on by stage. It defines the process of the technology, optimizes the adding point for medicament. The technology parameter is also defined: Htr(tinie water staying in tank) with 2.5-3.Oh,gas-water ratio with 2.5 - 3.5:1,capacity of medicament added in with 20-30mg/l,the mud consistency with 7-10g/l, Precipitation time with 1.2 - 1.5h.The study also tests the operating effect of the technology. It's shows that the degradation effect to NHs-N is most stable and list disturbed. The effect to CODCT is influence chiefly of the aeration capacity. With the gas-water ratio of 3.0-3.5:1,the degradation rate of CODCT goes to 70-80%. The degradation rate to TP depends on the capacity of medicament added in With the capacity up to 30mg/l the degradation rate to TP keeps below 0.5mg/l in the discharged water. The study indicates the mud consistency remains very high in the water in the biochemistry pond. The load of precipitating tank keeps larger. The precipitating time needs 1.2-1.5h,even the subsiding capability of mud being very good. At the same time the mud run off must be recirculated to keep the consistency in higher level inside the biochemistry pond.By way of the simulation test we study the feasibility of automatic recirculating of mud. It defines the train of thought to settle the problem of recirculating mud initially.This technology makes the capabilities of physics sticking, chemical flocculating of the new medicament combined organically with the biochemistry capability of microorganism, makes it give play to each superiority. It also makes the processing more efficiency and rapid and simply to light polluted water. It also widens the train ofnAbstractthought for the transformation of active mud technology of convention at the same time.
