Ozone-BAC Process For Micro-polluted Source Water Runs Effectiveness Analysis And Engineering Applications

Currently, due to the water environment is deteriorating and inadequate sewage treatment, resulting in most of our drinking water sources become micro-polluted water. The traditional conventional water purification process has been unable to effectively remove dissolved organic matter, ammonia and nitrite and other pollutants in raw water, can not meet the state drinking water quality standards, which will not only directly affect people’s health, and also to water treatment process has brought great difficulties, thus improving micro-polluted source water, improve drinking water quality and other issues has become a major task to be solved at present.This paper mainly includes three parts. The first part is mainly Ozone-BAC process technology, process mechanism, process characteristics and its influencing factors and preparation mechanism of ozone. The second part is the water through a comparative study of the effect of water quality analysis and running water before and after transformation of G water plant shows that Ozone-BAC process of micro-polluted water sources capable of water CODMn, ammonia and other organic pollution and Fe, Mn and other metal ions also have a good removal, and can effectively reduce the water mutagenic activity, to ensure residents safety of drinking water. The third part is X water plant Ozone-BAC process engineering example application, research practical engineering application determine of Ozone-BAC process water plant design and operating parameters of the calculation.Ozone-BAC process for micro-polluted water, dissolved organic matter in water, algae, color and disinfection byproducts have a good treatment effect. The G water plant using Ozone-BAC process after conventional treatment of advanced treatment process section and turbidity, color, manganese removal rates were 22%, 30% and 7%, respectively, the average water factory is 0.08 NTU, average value of less than 5 degrees, and 0.029 mg/L, good results. Removal of organic pollution better, CODMn, ammonia, nitrite, UV254 further removal rates reached 40%, 79%, 82% and 63%, respectively, to reduce the average water factory was 1.96mg/L, 0.03mg/L, 0.02mg/L and 0.04mg/L. Since X waterworks is currently under construction, there are no official production run, so this paper is only the starting point for the analysis of water quality as determined using ozone- biological activated carbon treatment process as X water advanced reatment, the main analysis is about Ozone-BAC of the process theory and research methods to determine the operating parameters of the main structures designed to provide some theoretical basis for future water plant construction and process of selection, to provide some reference value for the water plant design. Overall results showed that ozone-biological activated carbon treatment process as slightly polluted source water organic pollutants removal CODMn, ammonia, nitrite and other indicators largely enhance the existing water purification process, as excellent water, energy section, low pollution, green industrial water treatment technology will be widely applied and developed.
