Analysis and application of dewatering performance of sludge containing alcohol and oil

Gas field exploitation often produce some oil-alcohol-containing components of the sludge generated in the process of gathering and transportation complex,direct emissions will lead to the pollution of the surrounding environment.Experimental research concentrated on the settlement of oily alcoholcontaining sewage to reduce the emissions of harmful sludge to improve the treatment process,sludge samples,the experimental determination of the composition and particle size distribution analysis of the reasons for the poor separation,oil-containing alcohol to a gas field in northern Shaanxi;sludge dewatering performance,screening effective flocculant,to determine the best complex solutions and the dosage.Experimental results show that:mass concentration of 500mg/L of PAC and 30mg/L SC-3formula composite the flocculant sludge dewatering performance sedimentation treatment concentrated oilalcohol-containing sludge volume is reduced,the water content rate decreased,and the processing time is shortened.Field application test:formulation can effectively improve the treatment process and play a good role in the protection of the gas field environment.
