Gas Fields In West Water Treatment Process And Its Related Mechanism

In the base of investigate in the locale, we have consulted a lot of information. According to the analysis of the source, water quality characteristics, trend of gas field waste water, present treatment condition and dispose foreground, this paper bring forward the dispose process about gas field wastewater, coagulation and settling is the core of the process. After a series of experiments, we have confirmed the best technological process. The optimal coagulation and settling conditions are as following: [PFS]=300mg/l,[CPAM]=8mg/l,R=250r/p.m at PH=7. The topgallant conditions of Fenton reagent are as following :H2O2:Fe2+=1:1, 70℃ and 90 min. IMC-50S and EDTA were betaken in dispose of gas field wastewater . All mechanisms of the treating method have been studied. In the basis of experiments, we have investigated the microcosmic structure of floc about gas field wastewater in Sichuan province. Fractal dimension of floc have been mensured. In addition, two operation modes for compact floc formation-mechanical syneresis were discussed. It was proved that the technological process was good for the dispose of gas, field wastewater. The process has the advantages of simple fixing, small occ'upied surface area and high efficiency, so this process has definite foreground in the future.
